webservice的應用已經愈來愈普遍了,下面介紹幾種在Java體系中開發webservice的方式,至關於作個記錄。html
1.Axis2方式java
Axis是apache下一個開源的webservice開發組件,出現的算是比較早了,也比較成熟。這裏主要介紹Axis+eclipse開發webservice,固然不用eclipse也能夠開發和發佈webservice,只是用eclipse會比較方便。web
(1)下載eclipse的Java EE版本spring
http://www.eclipse.org/downloads/apache
(2)下載axis2api
http://axis.apache.org/axis2/java/core/download.cgi數組
(3)下載eclipse的axis2插件瀏覽器
Axis2_Codegen_Wizardtomcat
Axis2_Service_Archiver服務器
http://axis.apache.org/axis2/java/core/tools/index.html
推薦使用1.3的版本
(4)eclipse安裝axis2插件
1)在任意目錄下新建一個Axis2文件夾,在該文件夾下新建eclipse目錄,在eclipse目錄中新建plugins目錄和features目錄,例如:D:\programSoftware\eclipse-SVN\Axis2\eclipse;
2)把下載的axis2插件解壓,並把解壓的文件放到新建的eclipse的plugins目錄下;
3)在%eclipse_home%的目錄下新建links目錄,並在links目錄下新建axis2.link文件,內容爲:path=D:\programSoftware\eclipse-SVN\Axis2;
4)重啓eclipse,點擊·file-new-other,若是看到Axis2 Wizards,則代表插件安裝成功。
(5)安裝axis2
下載Axis2的WAR Distribution並解壓,把axis2.war包放置到%TOMCAT_HOME%/webapps下,啓動tomcat,訪問http://localhost:port/axis2,Axis2安裝成功。
(6)使用eclipse新建web工程,建立一個普通java類,至少包含一個方法。
(7)發佈webservice
1)點擊eclipse的File-New-other,打開Axis2 Wizards,選擇Axis2 Service Archiver,而後Next;
2)選擇Class File Location,也就是類文件存放路徑,注意:只選到classes目錄,不要包括包文件夾,而後Next;
3)選擇Skip WSDL,而後Next
4)一路Next到Select the Service XML file to be included in the Service archive,勾選Generate theservice xml automatically;
5)Service Name-填寫你的service名稱,Class Name-填寫類名稱,要包括包名,而後點擊load,而後點擊Finish,這時webservice就發佈成功了;
6)而後到%TOMCAT_HOME%/webapps/axis2/WEB-INF/services 看看是否多了一個.aar的文件;
7)訪問http://localhost:8085/axis2/services/類名?wsdl 就可看到生成的wsdl文件了。
注意:以上的方式是發佈到axis2.war包中,你也能夠把生成.aar文件copy到你的實際應用中,同時,你也可使用eclipse的create webservice功能發佈你的webservice,選擇axis2生成你的webservice,這樣webservice就會部署到你的應用中了。
2.Apche CXF方式
CXF開發webservice也是比較方便和簡單的,它和spring的集成能夠說是很是地好。舉一個CXF開發webservice的例子吧。
1)在eclipse中新建一個web工程,導入依賴包,如圖:
2)編寫一個接口,如:
public String test(@WebParam(name="value", targetNamespace = "http://service.cxf.zcl.com/", mode = WebParam.Mode.IN)String value);
注意:CXF開發的webservice,接口中的方法的參數必定要以這種方式,不然客戶端調用的時候CXF服務端會接收不到參數的值,name:參數名稱,可不寫(建議寫上),targetNamespace:命名空間,必定要填寫上,默認是包名反過來的順序,mode:參數類型,IN表示輸入。
3)編寫一個實現類,實現接口的方法;
4)和spring的集成,編寫一個bean文件,如:cxf-beans.xml,內容以下:
- <?xml version="1.0" encoding="UTF-8" ?>
- <beans xmlns="http://www.springframework.org/schema/beans"
- xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
- xmlns:jaxws="http://cxf.apache.org/jaxws"
- xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd
- http://cxf.apache.org/jaxws http://cxf.apache.org/schemas/jaxws.xsd">
-
- <import resource="classpath:META-INF/cxf/cxf.xml" />
- <import resource="classpath:META-INF/cxf/cxf-extension-soap.xml" />
- <import resource="classpath:META-INF/cxf/cxf-servlet.xml" />
-
- <jaxws:endpoint id="vote" implementor="com.zcl.cxf.service.VoteImpl" address="/Vote" />
- </beans>
這個文件比較容易理解,就不解釋了。
5)配置CXFServlet
在web.xml文件中配置CXFServlet,加載cxf-beans.xml文件,內容以下:
- <web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
- xmlns="http://java.sun.com/xml/ns/javaee" xmlns:web="http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"
- xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"
- id="WebApp_ID" version="2.5">
-
- <context-param>
- <param-name>contextConfigLocation</param-name>
- <param-value>WEB-INF/cxf-beans.xml</param-value>
- </context-param>
-
- <listener>
- <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
- </listener>
-
- <servlet>
- <servlet-name>cxf</servlet-name>
- <servlet-class>org.apache.cxf.transport.servlet.CXFServlet</servlet-class>
- <load-on-startup>1</load-on-startup>
- </servlet>
- <servlet-mapping>
- <servlet-name>cxf</servlet-name>
- <url-pattern>/services/*</url-pattern>
- </servlet-mapping>
- </web-app>
把工程部署到中間件,如tomcat,就能夠訪問該webservice了。
3.JDK開發webservice方式
1)編寫一個Java類,以下:
- package demo;
-
- import javax.jws.WebParam;
- import javax.jws.WebService;
- import javax.xml.ws.Endpoint;
-
- @WebService
- public class JdkWebService {
-
- public String doSomething(@WebParam(name="value", targetNamespace = "http://demo/", mode = WebParam.Mode.IN)String value) {
- return "Just do it," + value + "!";
- }
-
- public static void main(String[] args) {
- Endpoint.publish("http://localhost:8080/jdkwsdemo/demo.JdkWebService", new JdkWebService());
- }
- }
2)運行該java類,在瀏覽器上就能夠訪問該webservice了。
注意:開發web工程的時候,這種方法不太友好。咱們能夠編寫一個servlet類,在servlet類的初始化方法中發佈webservice,這樣咱們的中間件服務器啓動的時候就會幫咱們自動webservice了。
4. xfire方式
開發WebService的框架很多,每一個框架都有各自的有點,最近我用xfire練習開發WebService,下面是開發WebService的小例子,但願對入門的人有些小幫助
1.新建一個java web project命名爲TestWebService,將xfire相關的jar包添加到lib目錄中,寫接口類和實現類
- package com.lamp.service;
-
- public interface MessageService {
- public String getName(String name);
- }
實現類
- package com.lamp.service.impl;
-
- import com.lamp.service.MessageService;
-
- public class MessageServiceImpl implements MessageService {
-
- public String getName(String name) {
- return "hellow " + name + ", welcome to WebService world";
- }
-
- }
在src目錄下新建文件夾META-INF,而後再在其下新建文件夾xfire,在xfire目錄下新建配置文件services.xml
- <?xml version="1.0" encoding="UTF-8"?>
- <beans xmlns="http://xfire.codehaus.org/config/1.0">
- <service>
- <name>MessageService</name>
- <serviceClass>com.lamp.service.MessageService</serviceClass>
- <implementationClass>com.lamp.service.impl.MessageServiceImpl</implementationClass>
- </service>
- </beans>
最後在web.xml中配置xfire的servlet
- <servlet>
- <servlet-name>XFireServlet</servlet-name>
- <servlet-class>
- org.codehaus.xfire.transport.http.XFireConfigurableServlet
- </servlet-class>
- </servlet>
-
- <servlet-mapping>
- <servlet-name>XFireServlet</servlet-name>
- <url-pattern>/servlet/XFireServlet/*</url-pattern>
- </servlet-mapping>
-
- <servlet-mapping>
- <servlet-name>XFireServlet</servlet-name>
- <url-pattern>/services/*</url-pattern>
- </servlet-mapping>
項目部署後在瀏覽器中經過http://localhost:8080/TestWebService/services訪問看到遠程訪問的接口,並獲得wsdl爲http://localhost:8080/TestWebService/services/MessageService?wsdl
這樣服務器端開發完畢,如今開始客戶端的開發
新建一個java project也將xfire相關的jar引入,我用ant在客戶端生成代理對象,在項目路徑下新建build.xml,代碼爲
- <?xml version="1.0" encoding="UTF-8"?>
-
- <project name="WebService" basedir="." default="gen-webservice">
-
- <property file="build.properties">
- </property>
-
- <path id="project-classpath">
- <fileset dir="${lib.dir}">
- <include name="**/*.jar" />
- </fileset>
- </path>
-
- <target name="gen-webservice">
- <taskdef name="wsgen" classname="org.codehaus.xfire.gen.WsGenTask" classpathref="project-classpath" />
-
- <wsgen outputDirectory="${src.dir}"
- wsdl="${wsdl.dir}" package="com.lamp.ws.client" overwrite="true"/>
-
- </target>
-
- </project>
其引入的build.properties文件也在項目路徑下
src.dir=${basedir}/src
lib.dir=F:/WebService/xfire-1.2.6/lib
wsdl.dir=http://localhost:8080/TestWebService/services/MessageService?wsdl
其中lib.jar爲我存放xfire的路徑,運行ant獲得代理對象
編寫一個測試類
- package com.lamp.test;
-
- import com.lamp.ws.client.MessageServiceClient;
- import com.lamp.ws.client.MessageServicePortType;
-
- public class TestGetName {
-
- public static void main(String[] args) {
- MessageServiceClient msg = new MessageServiceClient();
- MessageServicePortType portType = msg.getMessageServiceHttpPort();
- String result = portType.getName("張三");
- System.out.println(result);
- }
-
- }
運行在控制檯看到了hellow 張三, welcome to WebService world至此一個簡單的WebService開發完畢
------------------------------------------------------------------------------------------------
webservice的應用已經愈來愈普遍了,下面介紹幾種在Java體系中開發webservice的方式,至關於作個記錄。
如今webservice加xml技術已經逐漸成熟,但要真正要用起來還需時日!!
因爲畢業設計緣故,我看了不少關於webservice方面的知識,今天和你們一塊兒來研究研究webservice的各類使用方法。
1、利用jdk web服務api實現,這裏使用基於 SOAP message 的 Web 服務
1.首先創建一個Web services EndPoint:
![](http://static.javashuo.com/static/loading.gif)
package Hello;
![](http://static.javashuo.com/static/loading.gif)
import javax.jws.WebService;
![](http://static.javashuo.com/static/loading.gif)
import javax.jws.WebMethod;
![](http://static.javashuo.com/static/loading.gif)
import javax.xml.ws.Endpoint;
![](http://static.javashuo.com/static/loading.gif)
@WebService
![](http://static.javashuo.com/static/loading.gif)
public class Hello {
![](http://static.javashuo.com/static/loading.gif)
@WebMethod
![](http://static.javashuo.com/static/loading.gif)
public String hello(String name) {
![](http://static.javashuo.com/static/loading.gif)
return "Hello, " + name + "\n";
![](http://static.javashuo.com/static/loading.gif)
}
![](http://static.javashuo.com/static/loading.gif)
public static void main(String[] args) {
![](http://static.javashuo.com/static/loading.gif)
// create and publish an endpoint
![](http://static.javashuo.com/static/loading.gif)
Hello hello = new Hello();
![](http://static.javashuo.com/static/loading.gif)
Endpoint endpoint = Endpoint.publish("http://localhost:8080/hello", hello);
![](http://static.javashuo.com/static/loading.gif)
}
![](http://static.javashuo.com/static/loading.gif)
}
2.使用 apt 編譯 Hello.java(例:apt -d [存放編譯後的文件目錄] Hello.java ) ,會生成 jaws目錄
3.使用java Hello.Hello運行,而後將瀏覽器指向http://localhost:8080/hello?wsdl就會出現下列顯示
![](http://static.javashuo.com/static/loading.gif)
4.使用wsimport 生成客戶端
使用以下:wsimport -p . -keep http://localhost:8080/hello?wsdl
這時,會在當前目錄中生成以下文件:
5.客戶端程序:
1
![](http://static.javashuo.com/static/loading.gif)
class HelloClient{
2
![](http://static.javashuo.com/static/loading.gif)
public static void main(String args[]) {
3
![](http://static.javashuo.com/static/loading.gif)
HelloService service = new HelloService();
4
![](http://static.javashuo.com/static/loading.gif)
Hello helloProxy = service.getHelloPort();
5
![](http://static.javashuo.com/static/loading.gif)
String hello = helloProxy.hello("你好");
6
![](http://static.javashuo.com/static/loading.gif)
System.out.println(hello);
7
![](http://static.javashuo.com/static/loading.gif)
}
8
![](http://static.javashuo.com/static/loading.gif)
}
9
以上方法還稍顯繁瑣,還有更加簡單的方法
2、使用xfire,我這裏使用的是myeclipse集成的xfire進行測試的
利用xfire開發WebService,能夠有三種方法:
1一種是從javabean 中生成;
2 一種是從wsdl文件中生成;
3 還有一種是本身創建webservice
步驟以下:
用myeclipse創建webservice工程,目錄結構以下:
首先創建webservice接口,
代碼以下:
1
![](http://static.javashuo.com/static/loading.gif)
package com.myeclipse.wsExample;
2
![](http://static.javashuo.com/static/loading.gif)
//Generated by MyEclipse
3
4
![](http://static.javashuo.com/static/loading.gif)
public interface IHelloWorldService {
5
6
![](http://static.javashuo.com/static/loading.gif)
public String example(String message);
7
8
![](http://static.javashuo.com/static/loading.gif)
}
接着實現這個藉口:
1
![](http://static.javashuo.com/static/loading.gif)
package com.myeclipse.wsExample;
2
![](http://static.javashuo.com/static/loading.gif)
//Generated by MyEclipse
3
4
![](http://static.javashuo.com/static/loading.gif)
public class HelloWorldServiceImpl implements IHelloWorldService {
5
6
![](http://static.javashuo.com/static/loading.gif)
public String example(String message) {
7
![](http://static.javashuo.com/static/loading.gif)
return message;
8
![](http://static.javashuo.com/static/loading.gif)
}
9
10
![](http://static.javashuo.com/static/loading.gif)
}
修改service.xml 文件,加入如下代碼:
1
![](http://static.javashuo.com/static/loading.gif)
<service>
2
![](http://static.javashuo.com/static/loading.gif)
<name>HelloWorldService</name>
3
![](http://static.javashuo.com/static/loading.gif)
<serviceClass>
4
![](http://static.javashuo.com/static/loading.gif)
com.myeclipse.wsExample.IHelloWorldService
5
![](http://static.javashuo.com/static/loading.gif)
</serviceClass>
6
![](http://static.javashuo.com/static/loading.gif)
<implementationClass>
7
![](http://static.javashuo.com/static/loading.gif)
com.myeclipse.wsExample.HelloWorldServiceImpl
8
![](http://static.javashuo.com/static/loading.gif)
</implementationClass>
9
![](http://static.javashuo.com/static/loading.gif)
<style>wrapped</style>
10
![](http://static.javashuo.com/static/loading.gif)
<use>literal</use>
11
![](http://static.javashuo.com/static/loading.gif)
<scope>application</scope>
12
![](http://static.javashuo.com/static/loading.gif)
</service>
把整個項目部署到tomcat服務器中 ,打開瀏覽器,輸入http://localhost:8989/HelloWorld/services/HelloWorldService?wsdl,能夠看到以下:
而後再展開HelloWorldService後面的wsdl能夠看到:
客戶端實現以下:
1
![](http://static.javashuo.com/static/loading.gif)
package com.myeclipse.wsExample.client;
2
3
![](http://static.javashuo.com/static/loading.gif)
import java.net.MalformedURLException;
4
![](http://static.javashuo.com/static/loading.gif)
import java.net.URL;
5
6
![](http://static.javashuo.com/static/loading.gif)
import org.codehaus.xfire.XFireFactory;
7
![](http://static.javashuo.com/static/loading.gif)
import org.codehaus.xfire.client.Client;
8
![](http://static.javashuo.com/static/loading.gif)
import org.codehaus.xfire.client.XFireProxyFactory;
9
![](http://static.javashuo.com/static/loading.gif)
import org.codehaus.xfire.service.Service;
10
![](http://static.javashuo.com/static/loading.gif)
import org.codehaus.xfire.service.binding.ObjectServiceFactory;
11
12
![](http://static.javashuo.com/static/loading.gif)
import com.myeclipse.wsExample.IHelloWorldService;
13
14
![](http://static.javashuo.com/static/loading.gif)
public class HelloWorldClient {
15
![](http://static.javashuo.com/static/loading.gif)
public static void main(String[] args) throws MalformedURLException, Exception {
16
![](http://static.javashuo.com/static/loading.gif)
// TODO Auto-generated method stub
17
![](http://static.javashuo.com/static/loading.gif)
Service s=new ObjectServiceFactory().create(IHelloWorldService.class);
18
![](http://static.javashuo.com/static/loading.gif)
XFireProxyFactory xf=new XFireProxyFactory(XFireFactory.newInstance().getXFire());
19
![](http://static.javashuo.com/static/loading.gif)
String url="http://localhost:8989/HelloWorld/services/HelloWorldService";
20
21
![](http://static.javashuo.com/static/loading.gif)
try
22
![](http://static.javashuo.com/static/loading.gif)
{
23
24
![](http://static.javashuo.com/static/loading.gif)
IHelloWorldService hs=(IHelloWorldService) xf.create(s,url);
25
![](http://static.javashuo.com/static/loading.gif)
String st=hs.example("zhangjin");
26
![](http://static.javashuo.com/static/loading.gif)
System.out.print(st);
27
![](http://static.javashuo.com/static/loading.gif)
}
28
![](http://static.javashuo.com/static/loading.gif)
catch(Exception e)
29
![](http://static.javashuo.com/static/loading.gif)
{
30
![](http://static.javashuo.com/static/loading.gif)
e.printStackTrace();
31
![](http://static.javashuo.com/static/loading.gif)
}
32
![](http://static.javashuo.com/static/loading.gif)
}
33
34
![](http://static.javashuo.com/static/loading.gif)
}
35
這裏再說點題外話,有時候咱們知道一個wsdl地址,好比想用java客戶端引用.net 作得webservice,使用myeclipse引用,可是卻出現沒法經過驗證的錯誤,這時咱們能夠直接在類中引用,步驟以下:
1
![](http://static.javashuo.com/static/loading.gif)
public static void main(String[] args) throws MalformedURLException, Exception {
2
![](http://static.javashuo.com/static/loading.gif)
// TODO Auto-generated method stub
3
![](http://static.javashuo.com/static/loading.gif)
Service s=new ObjectServiceFactory().create(IHelloWorldService.class);
4
![](http://static.javashuo.com/static/loading.gif)
XFireProxyFactory xf=new XFireProxyFactory(XFireFactory.newInstance().getXFire());
5
6
7
![](http://static.javashuo.com/static/loading.gif)
//遠程調用.net開發的webservice
8
![](http://static.javashuo.com/static/loading.gif)
Client c=new Client(new URL("http://www.webxml.com.cn/webservices/qqOnlineWebService.asmx?wsdl"));
9
![](http://static.javashuo.com/static/loading.gif)
Object[] o=c.invoke("qqCheckOnline", new String[]{"531086641","591284436"});
10
11
![](http://static.javashuo.com/static/loading.gif)
//調用.net本機開發的webservice
12
![](http://static.javashuo.com/static/loading.gif)
Client c1=new Client(new URL("http://localhost/zj/Service.asmx?wsdl"));
13
![](http://static.javashuo.com/static/loading.gif)
Object[] o1=c1.invoke("HelloWorld",new String[]{});
14
15
![](http://static.javashuo.com/static/loading.gif)
}
3、使用axis1.4調用webservice方法
前提條件:下載axis1.4包和tomcat服務器 ,並將axis文件夾複製到tomcat服務器的webapp文件夾中
這裏我就說一下最簡單的方法:
首先創建一個任意的java類(例如:HelloWorld.java),複製到axis文件夾下,將其擴展名改成jws,而後從新啓動tomcat,在瀏覽器中輸入http://localhost:8989/axis/HelloWorld.jws?wsdl,就會獲得一個wsdl文件,其客戶端調用方法以下:
1
![](http://static.javashuo.com/static/loading.gif)
import javax.xml.rpc.Service;
2
![](http://static.javashuo.com/static/loading.gif)
import javax.xml.rpc.ServiceException;
3
![](http://static.javashuo.com/static/loading.gif)
import javax.xml.rpc.ServiceFactory;
4
5
![](http://static.javashuo.com/static/loading.gif)
import java.net.MalformedURLException;
6
![](http://static.javashuo.com/static/loading.gif)
import java.net.URL;
7
![](http://static.javashuo.com/static/loading.gif)
import java.rmi.RemoteException;
8
9
![](http://static.javashuo.com/static/loading.gif)
import javax.xml.namespace.QName;
10
11
![](http://static.javashuo.com/static/loading.gif)
public class TestHelloWorld {
12
13
14
![](http://static.javashuo.com/static/loading.gif)
public static void main(String[] args) throws MalformedURLException, ServiceException, RemoteException {
15
![](http://static.javashuo.com/static/loading.gif)
// TODO Auto-generated method stub
16
17
![](http://static.javashuo.com/static/loading.gif)
String wsdlUrl ="http://localhost:8989/axis/HelloWorld.jws?wsdl";
18
![](http://static.javashuo.com/static/loading.gif)
String nameSpaceUri ="http://localhost:8989/axis/HelloWorld.jws";
19
![](http://static.javashuo.com/static/loading.gif)
String serviceName = "HelloWorldService";
20
![](http://static.javashuo.com/static/loading.gif)
String portName = "HelloWorld";
21
22
![](http://static.javashuo.com/static/loading.gif)
ServiceFactory serviceFactory = ServiceFactory.newInstance();
23
![](http://static.javashuo.com/static/loading.gif)
Service afService =serviceFactory.createService(new URL(wsdlUrl),new QName(nameSpaceUri, serviceName));
24
![](http://static.javashuo.com/static/loading.gif)
HelloWorldInterface proxy = (HelloWorldInterface)afService.getPort(new QName(nameSpaceUri, portName),HelloWorldInterface.class);
25
![](http://static.javashuo.com/static/loading.gif)
System.out.println("return value is "+proxy.getName("john") ) ;
26
27
![](http://static.javashuo.com/static/loading.gif)
}
28
29
![](http://static.javashuo.com/static/loading.gif)
}
30
4、使用axis2開發webservice(這裏首先感謝李寧老師)
使用axis2 須要先下載
axis2-1.4.1-bin.zip
axis2-1.4.1-war.zip
http://ws.apache.org/axis2/
同理,也須要將axis2複製到webapp目錄中
在axis2中部署webservice有兩種方法,
第一種是pojo方式,這種方式比較簡單,可是有一些限制,例如部署的類不能加上包名
第二種方式是利用xml發佈webservice,這種方法比較靈活,不須要限制類的聲明
下面分別說明使用方法:
1.pojo方式:在Axis2中不須要進行任何的配置,就能夠直接將一個簡單的POJO發佈成WebService。其中POJO中全部的public方法將被髮布成WebService方法。先實現一個pojo類:
1
![](http://static.javashuo.com/static/loading.gif)
public class HelloWorld{
2
![](http://static.javashuo.com/static/loading.gif)
public String getName(String name)
3
![](http://static.javashuo.com/static/loading.gif)
{
4
![](http://static.javashuo.com/static/loading.gif)
return "你好 " + name;
5
![](http://static.javashuo.com/static/loading.gif)
}
6
![](http://static.javashuo.com/static/loading.gif)
public int add(int a,int b)
7
![](http://static.javashuo.com/static/loading.gif)
{
8
![](http://static.javashuo.com/static/loading.gif)
return a+b;
9
![](http://static.javashuo.com/static/loading.gif)
}
10
![](http://static.javashuo.com/static/loading.gif)
}
11
因爲這兩個方法都是public類型,因此都會發布成webservice。編譯HelloWorld類後,將HelloWorld.class文件放到%tomcat%\webapps\axis2\WEB-INF\pojo目錄中(若是沒有pojo目錄,則創建該目錄),而後打開瀏覽器進行測試:
輸入一下url:
http://localhost:8080/axis2/services/listServices
會列出全部webservice
這是其中的兩個webservice列表,接着,在客戶端進行測試:
首先能夠寫一個封裝類,減小編碼,代碼以下:

客戶端調用方法:
2.使用service.xml發佈webservice,這種方式和直接放在pojo目錄中的POJO類不一樣。要想將MyService類發佈成Web Service,須要一個services.xml文件,這個文件須要放在META-INF目錄中,該文件的內容以下:
![](http://static.javashuo.com/static/loading.gif)
<service name="HelloWorld">
![](http://static.javashuo.com/static/loading.gif)
<description>
![](http://static.javashuo.com/static/loading.gif)
HelloWorld webservice
![](http://static.javashuo.com/static/loading.gif)
</description>
![](http://static.javashuo.com/static/loading.gif)
<parameter name="ServiceClass">
![](http://static.javashuo.com/static/loading.gif)
service.HelloWorld
![](http://static.javashuo.com/static/loading.gif)
</parameter>
![](http://static.javashuo.com/static/loading.gif)
<messageReceivers>
![](http://static.javashuo.com/static/loading.gif)
<messageReceiver mep="http://www.w3.org/2004/08/wsdl/in-out"
![](http://static.javashuo.com/static/loading.gif)
class="org.apache.axis2.rpc.receivers.RPCMessageReceiver" />
![](http://static.javashuo.com/static/loading.gif)
<messageReceiver mep="http://www.w3.org/2004/08/wsdl/in-only"
![](http://static.javashuo.com/static/loading.gif)
class="org.apache.axis2.rpc.receivers.RPCInOnlyMessageReceiver" />
![](http://static.javashuo.com/static/loading.gif)
</messageReceivers>
![](http://static.javashuo.com/static/loading.gif)
</service>
其中<service>元素用於發佈Web Service,一個<service>元素只能發佈一個WebService類,name屬性表示WebService名,以下面的URL能夠得到這個WebService的WSDL內容:
http://localhost:8080/axis2/services/myService?wsdl
除此以外,還有直接能夠在其中制定webservice操做方法:能夠這樣些service.xml文件
1
![](http://static.javashuo.com/static/loading.gif)
<service name="HelloWorld">
2
![](http://static.javashuo.com/static/loading.gif)
<description>

![](http://static.javashuo.com/static/loading.gif)
HelloWorld service

![](http://static.javashuo.com/static/loading.gif)
</description>
5
![](http://static.javashuo.com/static/loading.gif)
<parameter name="ServiceClass">
6
![](http://static.javashuo.com/static/loading.gif)
service.HelloWorld
7
![](http://static.javashuo.com/static/loading.gif)
</parameter>

![](http://static.javashuo.com/static/loading.gif)
<operation name="getName">

![](http://static.javashuo.com/static/loading.gif)
<messageReceiver class="org.apache.axis2.rpc.receivers.RPCMessageReceiver" />

![](http://static.javashuo.com/static/loading.gif)
</operation>
11
![](http://static.javashuo.com/static/loading.gif)
<operation name="add">

![](http://static.javashuo.com/static/loading.gif)
<messageReceiver

若是要發佈多個webservice,能夠在文件兩段加上<serviceGroup><service></service>...
