WebService--CXF与Spring的整合（jaxws:endpoint形式配置）以及客户端调用（spring配置文件形式，不需要生成客户端代码）

一、CXF与Spring整合（jaxws:endpoint形式配置）

工具要点：idea、maven

1.新建一个maven项目

pom.xml

2.web.xml文件中配置CXFServlet以及Spring容器，配置Spring的配置文件，配置webservice的配置文件

web.xml：

<!DOCTYPE web-app PUBLIC

 "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN"

 "http://java.sun.com/dtd/web-app_2_3.dtd" >

<web-app>

  <display-name>Archetype Created Web Application</display-name>

  <context-param>

    <param-name>contextConfigLocation</param-name>

    <param-value>classpath:applicationContext.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>/*</url-pattern>

  </servlet-mapping>

</web-app>

web.xml

applicationContext.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:context="http://www.springframework.org/schema/context"

       xsi:schemaLocation="

           http://www.springframework.org/schema/beans

           http://www.springframework.org/schema/beans/spring-beans-2.5.xsd

           http://www.springframework.org/schema/context

           http://www.springframework.org/schema/context/spring-context-2.5.xsd">

    <!-- 使用annotation 自动注册bean,并检查@Required,@Autowired的属性已被注入 -->

    <context:component-scan base-package="com.wp.learn.webservice"></context:component-scan>

    <!-- 导入其他配置文件 -->

    <import resource="applicationContext-ws.xml" />

</beans>

applicationContext-ws.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"

       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" />

    <jaxws:endpoint id="helloWebservice" implementor="#helloServiceImpl"

                    address="/hello" />

</beans>

接口HelloService：

Impl类HelloServiceImpl：

情况一、如果Impl类的注解是@Webservice，implementor需要写完全路径

情况二、Impl类注解是@Service，implementor只需“#”号加bean的id名

二、客户端调用（spring配置文件形式，不需要生成客户端代码）

　　Webservice的客户端调用，可以用ajax前端调用，java中可以通过生产客户端代码调用，也可以通过Spring配置文件、写对应接口信息调用。本例介绍配置文件，写接口信息进行webservice调用。

1.spring配置文件信息

<jaxws:client id="helloService" serviceClass="com.wp.learn.webservice.cxf.service.IHelloService"
　　 address="http://localhost:8080/ws/HelloService">

</jaxws:client>

2.写对应接口信息

需要注意两点：

1、targetNamespace的值必须和webservice服务项目中定义的一致，具体信息可以在WSDL文件中查看
2、接口名称可以自己随便起，但是方法名称、参数格式必须保持一致，否则无法找到服务的实现方法。

//注意，该出的targetNamespace的值必须和webService服务项目中定义的必须一致，否则调用不成功

@WebService(targetNamespace = "http://impl.service.cxf.webservice.learn.wp.com/", name = "IHelloService")

public interface IHelloService {

    //接口名称可以不一样，方法名称、参数格式必须保持一致，否则无法找到服务的实现的方法

    public String sayHi(String name);

}

3.加载Spring的配置文件进行测试

public class Test {

    public static void main(String[] args) {

        ApplicationContext context = new ClassPathXmlApplicationContext("applicationContext-ws.xml");

        IHelloService helloService = (IHelloService) context.getBean("helloService");

        String result = helloService.sayHi("帅哥");

        System.out.print(result);

    }

}

4.需要的jar包
