Spring 整合 Hessian

一：服务端

web.xml
	<!-- DispatcherServlet -->
	<servlet>
		<servlet-name>Spring-DispatcherServlet</servlet-name>
		<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
		<init-param>
			<param-name>contextConfigLocation</param-name>
			<param-value>/WEB-INF/config/applicationContext-hessianServer.xml</param-value>
		</init-param>
	</servlet>
	
	<servlet-mapping>
		<servlet-name>Spring-DispatcherServlet</servlet-name>
		<url-pattern>*.hessian</url-pattern>
	</servlet-mapping>

package com.xx.service;

/**
 * 服务接口 
 */
public interface ISayHelloService {

	/**
	 * @param name
	 * @return
	 */
	 String doSayHello(String name);
	 
	/**
	 * @param name
	 * @param welcomeStr
	 * @return
	 */
	 String doSayHello(String name, String welcomeStr);
}

package com.xx.service.impl;

import com.xx.service.ISayHelloService;

/**
 * 服务接口实现 
 */
public class DefaultSayHelloServiceImpl implements ISayHelloService {

	public String doSayHello(String name) {
		return doSayHello(name, "hello");
	}

	public String doSayHello(String name, String welcomeStr) {
		return name + "," + welcomeStr;
	}
}

</beans>

二：客户端 调用服务

package com.xx.service;

/**
 * 服务接口 
 */
public interface ISayHelloService {

	/**
	 * @param name
	 * @return
	 */
	 String doSayHello(String name);
	 
	/**
	 * @param name
	 * @param welcomeStr
	 * @return
	 */
	 String doSayHello(String name, String welcomeStr);
}

<?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" xmlns:tx="http://www.springframework.org/schema/tx"
	xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd
		http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-2.5.xsd
		http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.0.xsd
		http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-2.5.xsd">
	
	<!-- 客户端 -->
	<bean id="sayHelloService"  class="org.springframework.remoting.caucho.HessianProxyFactoryBean">
		<!-- 重载方法支持 不然会抛出异常  :Caused by: com.caucho.hessian.io.HessianProtocolException:  is an unknown code -->
		<property name="overloadEnabled"	value="true" />
		<property name="serviceUrl" 		value="http://localhost:8080/spring_hessian/sayHelloService.hessian" />
		<!-- 服务接口 -->
		<property name="serviceInterface" 	value="com.xx.service.ISayHelloService"/>
	</bean>
</beans>

 

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

import com.xx.service.ISayHelloService;

public class ClientMain {
	
	public static void main(String[] args) {
		ISayHelloService sayHelloService = getBean(ISayHelloService.class, "sayHelloService");
		System.out.println(sayHelloService.doSayHello("王五"));
		//客户端必须启用重载方法支持  不然会抛出Caused by: com.caucho.hessian.io.HessianProtocolException: '�' is an unknown code异常
		System.out.println(sayHelloService.doSayHello("李四", "welcome"));
	}
	
	public static <T> T getBean(Class<T> clazs, String beanName) {
		ApplicationContext applicationContext = new ClassPathXmlApplicationContext("applicationContext-client.xml");
		return clazs.cast(applicationContext.getBean(beanName));
	}
}
