webservice服务端

定义接口 HelloWorld

import javax.jws.WebService;

@WebService
public interface HelloWorld {
    String sayHi(String text);
}

实现接口 HelloWorldImpl

import me.shenzhun.webservice.service.HelloWorld;
import javax.jws.WebService;

@WebService(endpointInterface = "me.shenzhun.webservice.service.HelloWorld")
public class HelloWorldImpl implements HelloWorld {
    @Override
    public String sayHi(String text) {
        System.out.println("sayHi called");
        return "Hello, " + text;
    }
}

配置服务 cxf-servlet.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="me.shenzhun.webservice.service.impl.HelloWorldImpl"
            address="/HelloWorld"/>
</beans>

WEB服务配置 web.xml

<?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" 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_3_0.xsd" id="WebApp_ID" version="3.0">

webservice客户端

配置要调用的服务 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">

    <jaxws:client
            id="helloClient"
            serviceClass="me.shenzhun.webservice.service.HelloWorld"
            address="http://127.0.0.1:8080/HelloWorld"/>
</beans>

客户端调用 App

public class App {
    public static void main(String[] args) {
        ApplicationContext context = 
            new ClassPathXmlApplicationContext("classpath:config/beans.xml");
        HelloWorld client = (HelloWorld) context.getBean("helloClient");
        System.out.println(client.sayHi("Tom"));
    }
}
