hessian与spring的结合

对于EJB将被取代的说法已经比比皆是了，虽然我不认同吧，但是实话实说对于大多数的项目来说使用企业级的java bean还真的是没什么必要，因为太重量级了，上篇博客不是说了一下简单的hessian吗，这里就来说说hessian和spring的结合。

1、引入jar包

需要的jar包有：





2、配置remote-servlet.xml文件（在src目录下）

<?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"
       xmlns:aop="http://www.springframework.org/schema/aop"
       xsi:schemaLocation="http://www.springframework.org/schema/beans
       http://www.springframework.org/schema/beans/spring-beans.xsd        http://www.springframework.org/schema/context        http://www.springframework.org/schema/context/spring-context.xsd        http://www.springframework.org/schema/aop        http://www.springframework.org/schema/aop/spring-aop.xsd">        
    <!-- 接口的具体实现类 -->
    <bean id="impl" class="com.tgb.hessian.service.impl.HelloServiceImpl" />
    <!-- 使用Spring的HessianServie做代理 -->
    <bean name="/helloSpring"
    class="org.springframework.remoting.caucho.HessianServiceExporter">
        <!-- service引用具体的实现实体Bean-->
        <property name="service" ref="impl" />
        <property name="serviceInterface" value="com.tgb.hessian.service.HelloServiceSpring" />
    </bean>
    
    <!-- 可以配置多个HessianServiceExporter代理Bean -->
</beans>

3、配置web.xml文件

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://xmlns.jcp.org/xml/ns/javaee" xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-app_3_1.xsd" id="WebApp_ID" version="3.1">
  <display-name>Spring-Hessian</display-name>
  <welcome-file-list>  
    <welcome-file>index.jsp</welcome-file>  
  </welcome-file-list>  
<servlet>  
    <servlet-name>remote</servlet-name>  
    <!-- 使用Spring的代理Servlet -->  
    <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>  
    <init-param>  
        <param-name>namespace</param-name>  
        <param-value>classes/remote-servlet</param-value>  
    </init-param>  
    <load-on-startup>1</load-on-startup>  
</servlet>  
  
<servlet-mapping>  
    <servlet-name>remote</servlet-name>  
    <url-pattern>/remote/*</url-pattern>  
</servlet-mapping>    
</web-app>

4、服务接口和 接口的实现

（1）接口

package com.tgb.hessian.service;
public interface HelloServiceSpring {
    
    /**
     * hellworld 服务类接口
     * @author 陈丽娜
     * @version 2015年7月26日下午6:18:41
     * @return
     */
    public String HellowWorld(String name);
}

（2）实现

package com.tgb.hessian.service.impl;
import com.tgb.hessian.service.HelloServiceSpring;
/**
 * 服务实现类
 * @author 陈丽娜
 * @version 2015年7月26日下午9:17:03
 */
public class HelloServiceImpl implements HelloServiceSpring {
    @Override
    public String HellowWorld(String name) {
        // TODO Auto-generated method stub
        return "hello" + name;
    }
}

5、客户端的相关配置(同样需要引入spring的jar包和hessian的jar包，还有服务接口的jar。这里就不再赘述)

remote-client.xml配置

<?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"
       xmlns:aop="http://www.springframework.org/schema/aop"
       xsi:schemaLocation="http://www.springframework.org/schema/beans
       http://www.springframework.org/schema/beans/spring-beans.xsd        http://www.springframework.org/schema/context        http://www.springframework.org/schema/context/spring-context.xsd        http://www.springframework.org/schema/aop        http://www.springframework.org/schema/aop/spring-aop.xsd">        
    <!-- 客户端Hessian代理工厂Bean -->
    <bean id="clientSpring" class="org.springframework.remoting.caucho.HessianProxyFactoryBean">
        <!-- 请求代理Servlet路径 -->        
        <property name="serviceUrl">
         <value>http://localhost:8080/Spring-Hessian/remote/helloSpring</value>
        </property>
        <!-- 接口定义 -->
        <property name="serviceInterface">
            <value>com.tgb.hessian.service.HelloServiceSpring</value>
        </property>
    </bean>
</beans>

6、测试类的编写

package com.tgb.hessian.test;

import java.net.MalformedURLException;

import org.junit.Test;
import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;

import com.tgb.hessian.service.HelloServiceSpring;

public class TestHessianSpring {
	    @Test
		public void  Test1() throws MalformedURLException {
	    	ApplicationContext contex = new ClassPathXmlApplicationContext(  
	                "remote-client.xml");  
	  
	        // 获得客户端的Hessian代理工厂bean  
	        HelloServiceSpring i = (HelloServiceSpring) contex.getBean("clientSpring");  
	        System.out.println(i.HellowWorld("陈丽娜"));  
		}
	
}

7、运行结果：





是不是很简洁呢？！赶快学起来吧！
