hessian spring实例整合

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

1.hessian-api

hessian-api用于存放对外暴露接口；

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;
    }

}

        <property name="serviceInterface" value="com.xiaofeng.hessianserver.service.UserService" />
    </bean>-->

</beans>

3.hessian-client

hessian-client客户端调用

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
