Apache CXF是一个开源的WebService RPC框架。

例子:

1. 新建一个maven web项目, 添加pom

如下:

                </executions>
            </plugin>
        </plugins>
    </build>
</project>

 

2. 定义远程服务接口,并用@WebService标明是一个远程的WebService

package com.genesis.architect.cxf.service;

import javax.jws.WebService;

/**
 * @author KG created on 16/12/4
 */
@WebService
public interface HelloService {

    public String sayHello(String content);

}

 

3. 远程服务的实现(通过endpointInterface指明对应的接口)

package com.genesis.architect.cxf.service;

import javax.jws.WebService;

/**
 * @author KG created on 16/12/4
 */
@WebService(endpointInterface = "com.genesis.architect.cxf.service.HelloService")
public class HelloServiceImpl implements HelloService {

    @Override
    public String sayHello(String content) {
        return "hello," + content;
    }
}

 

4. 配置WebService的终结点实现,并配置地址映射

cxf-server.xml

<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-servlet.xml"/>
    <jaxws:endpoint id="helloWorld" implementor="com.genesis.architect.cxf.service.HelloServiceImpl" address="/HelloWorld"/>

</beans>

 

5. web.xml配置WebService监听,添加ws路由映射

<?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_2_5.xsd"
         id="WebApp_ID" version="2.5">

    <display-name>cxf-spring</display-name>

    <context-param>
        <param-name>contextConfigLocation</param-name>
        <param-value>classpath:cxf-server.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>
        <load-on-startup>1</load-on-startup>
    </servlet>
    <servlet-mapping>
        <servlet-name>CXFServlet</servlet-name>
        <url-pattern>/ws/*</url-pattern>
    </servlet-mapping>

</web-app>

 

6. 编写客户端测试

package com.genesis.architect.cxf.client;

import com.genesis.architect.cxf.service.HelloService;
import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;

/**
 * @author KG created on 16/12/4
 */
public class CxfClient {


    public static void main(String[] args) {
        ApplicationContext context = new ClassPathXmlApplicationContext("classpath:cxf-client.xml");
        HelloService client = (HelloService) context.getBean("helloClient");
        System.out.println(client.sayHello("Master HaKu"));
    }

}

 

7. 客户端调用远程服务的配置文件(cxf-client.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">


    <jaxws:client id="helloClient"
                  serviceClass="com.genesis.architect.cxf.service.HelloService"
                  address="http://localhost:8080/cxf-demo/ws/HelloWorld" />
</beans>

 

8. 运行结果

访问:

http://localhost:8080/cxf-demo/ws/HelloWorld?wsdl

可以看到soap的wsdl内容

运行client:

hello,Master HaKu
