Spring与apache CXF结合实例

本文的前提是已经有一个Spring的项目，在此基础上如何跟apache CXF进行结合，开发出WebService服务和调用WebService服务。

1.开发WebService

  1.引入jar包

  下载最新的jar包，并引入：\apache-cxf-3.0.1\lib\*（当然里面有些是不必要的，有兴趣的可以自己删减）。

  2.修改web.xml

<servlet>
        <servlet-name>cxf</servlet-name>
        <servlet-class>org.apache.cxf.transport.servlet.CXFServlet</servlet-class>
        <load-on-startup>2</load-on-startup>
    </servlet>
    <servlet-mapping>
        <servlet-name>cxf</servlet-name>
        <url-pattern>/services/*</url-pattern>
    </servlet-mapping>

  3.引入单独的spring配置文件cxf-servlet.xml

<!-- START SNIPPET: beans -->
<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="UserService"
        implementor="cn.telchina.standard.service.user.UserServiceImpl" address="/UserService" />
</beans>
<!-- END SNIPPET: beans -->

上述代码中：

    jaxsw:endpoint是关键。

在web.xml中加入配置

  4.开发服务接口和服务实现类

接口类：

package cn.telchina.standard.service.user;

import javax.jws.WebService;

/**
 * 必须要有接口
 * @author Administrator
 *
 */
@WebService
public interface UserService {

    public boolean updateTheUser(String user);

    public boolean updateUsersCode(String user);

}

接口实现类：

package cn.telchina.standard.service.user;

import javax.jws.WebService;

@WebService(endpointInterface = "cn.telchina.standard.service.user.UserService")
public class UserServiceImpl implements UserService {

    @Override
    public boolean updateTheUser(String user) {
        // TODO Auto-generated method stub
        return false;
    }

    @Override
    public boolean updateUsersCode(String user) {
        // TODO Auto-generated method stub
        return false;
    }

}

此时发布程序即可：

http://localhost:8080/cxfProject/services

http://localhost:8080/cxfProject/services/UserService?wsdl

2.调用WebService

调用ＣＸＦ服务的方式有三种：

1.配置spring bean的方式

   新增配置文件：client-beans,并在web.xml中配置。

Client-beans.xml内容

<?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:oxm="http://www.springframework.org/schema/oxm"
    xmlns:jaxws="http://cxf.apache.org/jaxws"
    xsi:schemaLocation="http://www.springframework.org/schema/beans
    http://www.springframework.org/schema/beans/spring-beans-3.0.xsd
    http://www.springframework.org/schema/oxm
    http://www.springframework.org/schema/oxm/spring-oxm-3.0.xsd
    http://cxf.apache.org/jaxws
    http://cxf.apache.org/schemas/jaxws.xsd"> 

        <jaxws:client id="client"
        address="http://localhost:8080/cxfProject/services/UserService"
        serviceClass="cn.telchina.standard.service.user.UserService" />
</beans>

java代码：

public static void invokeBySpring(){
        // TODO Auto-generated method stub
                ClassPathXmlApplicationContext context = new ClassPathXmlApplicationContext(
                        new String[] { "client-beans.xml" });

                UserService client = (UserService) context.getBean("client");

                boolean response = client.updateTheUser("Joe");
                System.out.println("Response: " + response);
    }

2.CXF的方式

public static void invokeService(){
            JaxWsProxyFactoryBean factory = new JaxWsProxyFactoryBean();
            factory.setServiceClass(UserService.class);
            factory.setAddress("http://localhost:8080/cxfProject/services/UserService");
            UserService service = (UserService) factory.create();  

            boolean response = service.updateTheUser("Joe");
            System.out.println("#############"+response+"##############");
    }

3.RPC方式

public static void invokeService2() throws Exception{
         //这个是用cxf 客户端访问cxf部署的webservice服务
        //千万记住，访问cxf的webservice必须加上namespace ,否则通不过
        //现在又另外一个问题，传递过去的参数服务端接收不到
        JaxWsDynamicClientFactory dcf = JaxWsDynamicClientFactory.newInstance();
        org.apache.cxf.endpoint.Client client = dcf.createClient("http://localhost:8080/cxfProject/services/UserService?wsdl");
        //url为调用webService的wsdl地址
        QName name=new QName("http://user.service.standard.telchina.cn/","updateTheUser");
        //namespace是命名空间，methodName是方法名
        String xmlStr = "name";
        //paramvalue为参数值
        Object[] objects=client.invoke(name,xmlStr);
        //调用web Service//输出调用结果
        System.out.println(objects[0].toString());
    }

PS：

   cxf的类库和axis2的类库不能放到一个项目中，否者会报错：

Invocation of init method failed; nested exception is java.lang.NoSuchFieldError: REFLECTION
