Apache CXF實現的SOAP形式的webservices

前言:經常使用的web service有兩種形式,SOAP和RESTful。這裏先說SOAP的實現步驟,RESTful的形式後面再說html

一 建項目,導jar包java

(1)項目結構web

wKioL1cKUAPiI8TiAAA4VVm9CRU924.png


(2)在eclipse中新建一個動態web項目「CXFDemo」,並導入cxf中的jar包(路徑:/WEB-INF/lib/)。固然,能夠去官網下載,也能夠直接使用我用過的jar包,連接:http://pan.baidu.com/s/1pKyelAVspring

(3)配置web.xml:apache

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
	xmlns="http://java.sun.com/xml/ns/javaee"
	xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd"
	version="3.0">
	<display-name>CXFDemo</display-name>
	<context-param>
		<param-name>contextConfigLocation</param-name>
		<param-value>WEB-INF/classes/service-beans.xml</param-value>
	</context-param>
	<listener>
		<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
	</listener>
	<servlet>
		<servlet-name>CXFServlet</servlet-name>
		<servlet-class>org.apache.cxf.transport.servlet.CXFServlet</servlet-class>
	</servlet>
	<servlet-mapping>
		<servlet-name>CXFServlet</servlet-name>
		<url-pattern>/*</url-pattern>
	</servlet-mapping>
	<welcome-file-list>
		<welcome-file>index.html</welcome-file>
		<welcome-file>index.htm</welcome-file>
		<welcome-file>index.jsp</welcome-file>
		<welcome-file>default.html</welcome-file>
		<welcome-file>default.htm</welcome-file>
		<welcome-file>default.jsp</welcome-file>
	</welcome-file-list>
</web-app>


二 web service服務端類tomcat

(1)接口CXFService.java:app

package cn.zifangsky;

import javax.jws.WebMethod;
import javax.jws.WebParam;
import javax.jws.WebService;

@WebService
public interface CXFService {
	@WebMethod
	public String sayHello(@WebParam(name="name") String name);
}

說明:
@WebService:標記表示該接口是一個WebService服務
@WebMethod:標記表示WebService中的方法
@WebParam(name=」paramName」)表示方法中的參數,name屬性限制了參數的名稱,若沒有指定該屬性,參數將會被重命名eclipse

(2)具體的實現類CXFServiceImpl.java:jsp

package cn.zifangsky.impl;

import cn.zifangsky.CXFService;

public class CXFServiceImpl implements CXFService {
	
	public String sayHello(String name) {
		return "Hello," + name + "\n" + Test.getExtraMessage();
	}

}

注:Test.java類:ide

package cn.zifangsky.impl;

public class Test {
	public static String getExtraMessage(){
		return "測試";
	}
}

(3)配置service-beans.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:jaxws="http://cxf.apache.org/jaxws" xmlns:soap="http://cxf.apache.org/bindings/soap"
	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">
	
	<bean id="outLoggingInterceptor" class="org.apache.cxf.interceptor.LoggingOutInterceptor" />
	<bean id="loggingFeature" class="org.apache.cxf.feature.LoggingFeature" />
	<bean id="inLoggingInterceptor" class="org.apache.cxf.interceptor.LoggingInInterceptor" />
	<jaxws:server id="sayHelloServices" serviceClass="cn.zifangsky.CXFService" address="/soap/sayHello" >
		<jaxws:serviceBean>
			<bean class="cn.zifangsky.impl.CXFServiceImpl" />
		</jaxws:serviceBean>
		<jaxws:outInterceptors>
			<ref bean="outLoggingInterceptor" />
		</jaxws:outInterceptors>
		<jaxws:inInterceptors>
			<ref bean="inLoggingInterceptor" />
		</jaxws:inInterceptors>
		<jaxws:features>
			<ref bean="loggingFeature" />
			<wsa:addressing xmlns:wsa="http://cxf.apache.org/ws/addressing" />
		</jaxws:features>
		
	</jaxws:server>
		
</beans>

說明:

i)3個bean配置的是日誌,在這裏把日誌相關的配置刪掉也不影響web service服務的正常使用

ii)address指的是發佈後這個服務的路徑問題,好比說我這裏就是:http://localhost:8080/CXFDemo/soap/sayHello

(4)測試

發佈這個項目到tomcat,運行以後的效果以下:

wKioL1cKULbSOMPAAAA-e5SuiHc509.png

點擊那個連接,能夠發現sayHello這個服務的地址是:http://localhost:8080/CXFDemo/soap/sayHello?wsdl

到此,這個web service的服務端已經配置完成


三 web service客戶端配置

服務端提供服務,而客戶端使用服務端提供的服務,所以客戶端只須要調用服務端提供的服務就能夠了

(1)客戶端的項目結構:

wKioL1cKUOWRR2GiAAAtfhKE4Tg645.png

(2)一樣是新建一個動態web工程,而後引入cxf的jar包,同時須要把服務端的CXFService接口打包成一個jar包,而後導入到客戶端的lib中,連接:http://pan.baidu.com/s/1eQVWups

wKiom1cKUF7QAMy_AAB6UBqzXRY701.png

(3)客戶端測試類ClientDemo.java:

package cn.zifangsky.client;

import org.springframework.context.support.ClassPathXmlApplicationContext;

import cn.zifangsky.CXFService;

public class ClientDemo {
	public static void main(String args[]){
		ClassPathXmlApplicationContext context = new ClassPathXmlApplicationContext(new String[] {"client-beans.xml"});
		
		CXFService clientHello = (CXFService) context.getBean("clientHello");
		String response = clientHello.sayHello("javaee");
		context.close();
		
		System.out.println("Response: " + response);   
        System.exit(0);  
	} 
	
}

(4)客戶端配置文件client-beans.xml:

<?xml version="1.0" encoding="UTF-8"?>  
<beans xmlns="http://www.springframework.org/schema/beans"   
       xmlns:jaxws="http://cxf.apache.org/jaxws"   
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"   
       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">  
         
    <bean id="outLoggingInterceptor" class="org.apache.cxf.interceptor.LoggingOutInterceptor" />
	<bean id="loggingFeature" class="org.apache.cxf.feature.LoggingFeature" />
	<bean id="inLoggingInterceptor" class="org.apache.cxf.interceptor.LoggingInInterceptor" />      
    <jaxws:client id="clientHello" serviceClass="cn.zifangsky.CXFService" address="http://localhost:8080/CXFDemo/soap/sayHello?wsdl">
    	<jaxws:inInterceptors>
			<ref bean="inLoggingInterceptor" />
		</jaxws:inInterceptors>
		<jaxws:outInterceptors>
			<ref bean="outLoggingInterceptor" />
		</jaxws:outInterceptors>
		<jaxws:features>
			<ref bean="loggingFeature" />
			<wsa:addressing xmlns:wsa="http://cxf.apache.org/ws/addressing" />
		</jaxws:features>
    </jaxws:client>   
</beans>

說明:

這裏的address須要填寫服務的wsdl絕對地址,所以這裏就是:http://localhost:8080/CXFDemo/soap/sayHello?wsdl


(5)測試

Response: Hello,javaee
測試

能夠發現,最後成功輸出了

Response: Hello,javaee
測試

由於咱們在客戶端中只引用了CXFService.java這個接口,可是卻輸出了預期的內容,說明客戶端的確是調用了服務端的服務併成功返回信息的
