Hessian是一个轻量级的remoting onhttp工具，使用简单的方法提供了RMI的功能。 相比WebService，Hessian更简单、快捷。采用的是二进制RPC协议，因为采用的是二进制协议，所以它很适合于发送二进制数据。

架构

![Center][]

1.hessian-api

hessian-api用于存放对外暴露接口；

![Center 1][]

package com.xiaofeng.hessian.api;
    
    /**
     * @author zhangweixiang
     * @desc 一句话来描述这个类的作用
     * @date $date$ $time$
     */
    public interface UserService {
    
        void addUser();
    
        void updateUser();
    
        void delUser();
    
        String findUser(String username);
    }

2.hessian-server

hessian-server服务端

服务实现类：

package com.xiaofeng.hessianserver.service;
    
    import com.xiaofeng.hessian.api.UserService;
    
    /**
     * @author zhangweixiang
     * @desc 一句话来描述这个类的作用
     * @date $date$ $time$
     */
    public class UserServiceImpl implements UserService {
    
        public void addUser() {
            System.out.println("-------------invoke addUser()---------------");
        }
    
        public void updateUser() {
            System.out.println("-------------invoke updateUser()---------------");
        }
    
        public void delUser() {
            System.out.println("-------------invoke delUser()---------------");
        }
    
        public String findUser(String username) {
            System.out.println("-------------invoke findUser---------------");
            return "return: " + username;
        }
    
    }

3.hessian-client

hessian-client客户端调用

![Center 3][]

![Image 1][]

import com.xiaofeng.hessian.api.UserService;
    import org.junit.Test;
    import org.junit.runner.RunWith;
    import org.springframework.beans.factory.annotation.Autowired;
    import org.springframework.test.context.ContextConfiguration;
    import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;
    
    /**
     * @author zhangweixiang
     * @desc 一句话来描述这个类的作用
     * @date $date$ $time$
     */
    @RunWith(SpringJUnit4ClassRunner.class)
    @ContextConfiguration("/springmvc-servlet.xml")
    public class HessianTest {
        @Autowired
        private UserService userService;
    
        @Test
        public void test() {
            userService.addUser();
            userService.updateUser();
            userService.delUser();
            String user = userService.findUser("ZhangSan");
            System.out.println(user);
            System.out.println("--------- ------------------------finished----------------------------------");
        }
    }

启动服务端，然后通过客户端test调用即可
