什麼是WebService?webService小示例 點此瞭解html
下面進入正題:java
Java web項目(spring項目)中集成webservice ,實現對外開放接口步驟:web
準備:spring
採用與spring兼容性較好的cxf來實現apache
cxf 的 jar下載地址: http://cxf.apache.org/download.htmlapi
選擇zip格式下載,解壓後的lib目錄下的jar瀏覽器
須要最少的jar以下:服務器
cxf-2.3.3.jar
geronimo-annotation_1.0_spec-1.1.1.jar
geronimo-jaxws_2.2_spec-1.0.jar
geronimo-stax-api_1.0_spec-1.0.1.jar
geronimo-ws-metadata_2.0_spec-1.1.3.jar
jaxb-api-2.2.1.jar
jaxb-impl-2.2.1.1.jar
neethi-2.0.4.jar
wsdl4j-1.6.2.jar
XmlSchema-1.4.7.jar
wstx-asl-3.2.9.jarapp
一:建立webservice服務器測試
1)建立一個服務接口
- package com.service;
-
- import javax.jws.WebParam;
- import javax.jws.WebService;
-
- @WebService
- public interface IHelloWorld {
- public String sayHello(@WebParam(name = "arg0") String text);
- }
2)是接口實現類
- package com.service.impl;
-
- import javax.jws.WebService;
-
- import com.service.IHelloWorld;
-
- @WebService(endpointInterface = "com.service.IHelloWorld")
- public class HelloWorldImpl implements IHelloWorld {
- public String sayHello(String text) {
- return "Hello : " + text;
- }
- }
3)建立spring配置文件,將服務類加入到容器中
webservice.xml
- <?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:p="http://www.springframework.org/schema/p"
- xmlns:jaxws="http://cxf.apache.org/jaxws"
- xmlns:cxf="http://cxf.apache.org/core"
- xsi:schemaLocation="http://www.springframework.org/schema/beans
- http://www.springframework.org/schema/beans/spring-beans-2.5.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" />
-
-
- <bean id="hello" class="com.service.impl.HelloWorldImpl"/>
- <jaxws:endpoint id="helloWorld" implementor="#hello" address="/HelloWorld" />
- </beans>
在web.xml中添加webservice.xml配置文件
- <context-param>
- <param-name>contextConfigLocation</param-name>
- <param-value>
- /WEB-INF/webservice.xml
- </param-value>
- </context-param>
4)在web.xml中加入cxf servlet
- <servlet>
- <display-name>CXF Servlet</display-name>
- <servlet-name>CXFServlet</servlet-name>
- <servlet-class>org.apache.cxf.transport.servlet.CXFServlet</servlet-class>
- <load-on-startup>1</load-on-startup>
- </servlet>
-
- <servlet-mapping>
- <servlet-name>CXFServlet</servlet-name>
- <url-pattern>/webservice/*</url-pattern>
- </servlet-mapping>
至此,webservice服務器就建立好了,
在瀏覽器中訪問:http://localhost:8080/test/webservice/HelloWorld?wsdl,(test是項目名稱)。若是出現了相似與
<wsdl:definitions xmlns:ns1="http://service.com/" xmlns:soap="http://schemas.xmlsoap.org/wsdl/soap/" xmlns:tns="http://impl.service.com/" xmlns:wsdl="http://schemas.xmlsoap.org/wsdl/" xmlns:xsd="http://www.w3.org/2001/XMLSchema" name="HelloWorldImplService" targetNamespace="http://impl.service.com/">
。。。。
就配置成功了。
接下來貼幾個運行時的錯誤解決方法
1:webservice.xml中提示cxf.xml,cxf-servlet.xml not found,我在上面寫的路徑是classpath*:META-INF/cxf/cxf.xml,這裏的classpath後面還跟了一個「*」符號,沒加符號表示只在類路徑下查找cxf.xml文件,加了號表示不只在類路徑下查找xml文件,還在jar包中查找xml文件。因此當咱們在項目類路徑下沒有假如cxf.xml等配置文件時,就必定要在classpath後加*,這樣spring容器纔會去所加入的jar包中找。
2:假如cxf servlet時,映射路徑不要寫成/*,不然會出現訪問不了項目主頁的狀況,能夠寫成/webservice/*或者別的項目中沒有使用過的路徑來做爲cxf servlet的請求路徑。
二:建立webservice客戶端
客戶端能夠和服務器放在同一個項目中用來測試,也能夠新建一個Java項目來進行測試。
新建一個Java項目測試時,要假如對應的jar包,跟服務器同樣,使用spring還要假如spring jar包。
我在這裏新建一個項目,依舊使用spring來測試
1)首先要建立一個和服務器端同樣的服務接口,(若是客戶端和服務器端在同一個項目中則能夠省略這步)
- package com.service;
-
- import javax.jws.WebParam;
- import javax.jws.WebService;
-
- @WebService
- public interface IHelloWorld {
- public String sayHello(@WebParam(name = "arg0") String text);
- }
2)建立spring-client.xml,
- <?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:p="http://www.springframework.org/schema/p"
- xmlns:jaxws="http://cxf.apache.org/jaxws" xmlns:cxf="http://cxf.apache.org/core"
- xsi:schemaLocation="http://www.springframework.org/schema/beans
- http://www.springframework.org/schema/beans/spring-beans-2.5.xsd
- http://cxf.apache.org/jaxws
- http://cxf.apache.org/schema/jaxws.xsd">
-
- <bean id="client" class="com.service.IHelloWorld" factory-bean="clientFactory" factory-method="create" />
- <bean id="clientFactory" class="org.apache.cxf.jaxws.JaxWsProxyFactoryBean">
- <property name="serviceClass" value="com.service.IHelloWorld" />
- <property name="address" value="http://localhost:8080/test/HelloWorld" />
- </bean>
- </beans>
3)測試類
- package com.test;
-
- import org.springframework.context.ApplicationContext;
- import org.springframework.context.support.ClassPathXmlApplicationContext;
-
- import com.service.IHelloWorld;
-
- public class Test {
- public static void main(String[] args) {
- ApplicationContext ctx = new ClassPathXmlApplicationContext("spring-client.xml");
- IHelloWorld client = (IHelloWorld) ctx.getBean("client");
- String result = client.sayHello("你好!");
- System.out.println(result);
- }
- }
運行成功後顯示
Hello:你好!
