Apache CXF 2.7与Spring 3集成
来源:互联网 发布:淘宝买家旺旺 编辑:程序博客网 时间:2024/05/21 12:35
做项目时,涉及到多个异构系统的交互,采用了Apache CXF,下面通过实例演示Apache CXF 2.7与spring集成,发布和调用Web Service。
环境:
win8 64位
tomcat 7 64位
jdk 7 64位
cxf 2.7
spring 3
项目结构
1、在同一个项目中模仿服务端和客户端(实际项目中是不可能的,但是客户端却依赖于服务端的Web Service接口,那么可以通过导出jar的方式)
类库
在apache cxf 官网下载cxf2.7,解压,在lib下即可找到这些jar
几个类的代码
- package com.test.server;
-
- import javax.jws.WebService;
-
-
- @WebService
- public interface IHelloWorldServer {
- public String sayHello(String username);
- }
- package com.test.server;
-
- import javax.jws.WebService;
-
- @WebService(endpointInterface = "com.test.server.IHelloWorldServer", serviceName = "HelloService")
- public class HelloWorldServerImp implements IHelloWorldServer{
-
- @Override
- public String sayHello(String username) {
-
- return username+" : HelloWorld";
- }
-
- }
- package com.test.client;
-
- import org.springframework.context.ApplicationContext;
- import org.springframework.context.support.ClassPathXmlApplicationContext;
-
- import com.test.server.IHelloWorldServer;
-
- public class HelloWorldClient {
- public static void main(String[] args) {
- ApplicationContext context = new ClassPathXmlApplicationContext("applicationContext-client.xml");
- IHelloWorldServer helloService = (IHelloWorldServer) context.getBean("client");
- String response = helloService.sayHello("jialin");
- System.out.println(response);
- }
-
- }
相应的配置文件applicationContext-server.xml

配置完成后,部署到tomcat,成功启动后。
在浏览器中输入
http://localhost:8080/cxf_demo/ws
说明web service发布成功,可以点击进入查看相应的WSDL.
这时运行客户端得到如下结果
以上是在同一个项目中模仿客户端和服务端。下面再看一个服务和客户端不在同一个项目中的,这是符合现实的。
2、
服务端
与上述项目结构一样,只是没有com.test.client这个包和applicationContext-client.xml
客户端
新建一个普通的Java项目即可,项目结构:
注意cxf-serverinterface这个jar,是到处的服务端的接口即为com.test.server.IHelloWorld
HelloWorldClient.java
- package com.test.client;
-
-
- import org.springframework.context.ApplicationContext;
- import org.springframework.context.support.ClassPathXmlApplicationContext;
-
-
- import com.test.server.IHelloWorldServer;
-
-
- public class HelloWorldClient {
- public static void main(String[] args) {
- ApplicationContext context = new ClassPathXmlApplicationContext("applicationContext-client.xml");
- IHelloWorldServer helloService = (IHelloWorldServer) context.getBean("client");
- String response = helloService.sayHello("jialin");
- System.out.println(response);
- }
-
-
- }
applicationContext-client.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.xsd
- http://cxf.apache.org/jaxws http://cxf.apache.org/schemas/jaxws.xsd">
- <!--
- ***注意***
- 手动添加的内容:
- xmlns:jaxws="http://cxf.apache.org/jaxws"
- 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" />
-
- <bean id="client" class="com.test.server.IHelloWorldServer" factory-bean="clientFactory" factory-method="create" />
-
- <bean id="clientFactory" class="org.apache.cxf.jaxws.JaxWsProxyFactoryBean">
- <property name="serviceClass" value="com.test.server.IHelloWorldServer" />
- <property name="address" value="http://localhost:8080/cxf_demo/ws/helloService" />
- </bean>
- </beans>
测试:
部署服务端到tomcat,启动。
启动Web Service服务,然后访问http://localhost:8080/cxf_demo/ws地址来确定web service启动正确。
运行Client测试类,运行结果:
成功!
