Web Service学习-CXF与Spring整合为JavaEE应用发布WebService(三)

CXFSpring整合,分两个方面给大家介绍:

 

1,在传统ssh项目基础上添加Web Service

赋值CXFjar

web.xml配置文件中导入CXF的核心控制器:CXFServlet

Spring配置文件中导入CXF提供Schemaxml配置文件

Spring配置文件中使用jaxws:endpoint元素来暴露Web Service

如果要添加拦截器,在jaxws:endpoint元素里添加

inInterceptors,outInterceptors子元素

2,远程调用Web Service服务(让Action依赖远程Web Service的接口)

复制CXFjar

Spring配置文件中导入CXF提供Schemaxml配置文件

Spring配置文件中使用jaxws:client元素来配置远程Web Service代理

如果要添加拦截器。在jaxws:client元素里添加

inInterceptors,outInterceptors子元素

 

第一个方面:提供Web Service的服务


服务端:

在相应的SSH项目中添加CXF的相关jar包:

以上配置已经完成,对于接口和相应的实现参考之前的博客即可,实现中对于new的内容使用spring管理起来

 

HelloWorldImpl:

package com.tgb.service.impl;

import java.util.Date;
import java.util.List;
import java.util.Map;

import javax.jws.WebService;

import com.tgb.domain.Cat;
import com.tgb.domain.User;
import com.tgb.service.HelloWorld;
import com.tgb.service.UserService;

@WebService(endpointInterface="com.tgb.service.HelloWorld",serviceName="HelloWorldImpl")
public class HelloWorldImpl implements HelloWorld{

	private UserService userService;
	
	public UserService getUserService() {
		return userService;
	}

	public void setUserService(UserService userService) {
		this.userService = userService;
	}

	public String sayHi(String name) {
			
		return name+"您好!现在时间为:"+new Date();
	}
	
	@Override
	public List<Cat> getCatsByUser(User user) {
		//在实际项目中,web service组件自己并不会去实现业务功能
		//它只是调用业务逻辑组件的方法来暴露web service
//		UserService us=new UserServiceImpl();
		
		return userService.getCatsByUser(user);
	}

	@Override
	public Map<String, Cat> getAllCats() {
//		UserService us=new UserServiceImpl();
		return userService.getAllCats();
	}

	
}

新建客户端项目CXF_Spring_Client,生成客户端代码:




注意:

有些版本拷贝后,类中的super()会出错,要加上-frontendjaxws21,参看如上截图

 

客户端调用:


package com.tgb.client;

import java.util.List;

import org.apache.cxf.endpoint.Client;
import org.apache.cxf.frontend.ClientProxy;

import com.tgb.auth.AddHeaderInterceptor;
import com.tgb.service.Cat;
import com.tgb.service.HelloWorld;
import com.tgb.service.User;
import com.tgb.service.impl.HelloWorldImpl;

public class client {

	public static void main(String[] args){
		HelloWorldImpl factory=new HelloWorldImpl();
		//此处返回的只是远程Web Service的代理
		HelloWorld hw=factory.getHelloWorldImplPort();
		
		/**
		 * 添加的拦截器
		 */
		Client client=ClientProxy.getClient(hw);
		//参数为输入的用户名,密码
		client.getOutInterceptors().add(new AddHeaderInterceptor("hejingyuan","hjy"));
		
		
		System.out.println(hw.sayHi("hejingyuan"));		
		System.out.println("--------------------------");
		
		User user=new User();
		user.setId(20);
		user.setName("孙悟空");
		user.setPass("111");
		user.setAddress("花果山");
		
		List<Cat> cats=hw.getCatsByUser(user);
		for(Cat cat:cats){
			System.out.println(cat.getName());
		}
		
		System.out.println("--------------------------");
		
		System.out.println(hw.getAllCats().getEntry().get(0).getKey());
		System.out.println(hw.getAllCats().getEntry().get(0).getValue().getName());
		
	}
}

由于我们在服务端添加了拦截器,故客户端必须要添加相应的拦截器给服务端提供参数,否则客户端调用失败

另一个方面:调用远程的Web Service服务

总结:


     以上与Spring的整合,概括的说,在应用Spring的框架过程中,一种是我们如何对外提供服务,另一种是我们如何获取已经提供好的服务。在整个过程中,只有几个关键点,很简单,但是要注意jar包的版本问题。
