SpringBoot中添加Hessian框架

Hessian一般用来做RPC接口，通过http传输二进制文件，用于程序和程序之间的通信。 在这个例子中，有两个项目，客户端(hessianClient)和主项目(asset)

1.新建一个Springboot项目

导入依赖为

org.springframework.boot

spring-boot-starter

org.springframework.boot

spring-boot-starter-test

test

org.springframework.boot

spring-boot-starter-web

com.caucho

hessian

4.0.33

2.写调用的接口文件

MyHessianService.java

package com.ucardemo.asset.api;

import com.ucardemo.asset.model.User;

public interface MyHessianService {

public String justHadEnoughParties();

public boolean checkLogin(User user);

}

MyHessianServiceImpl.java

@Service("myHessianService")

public class MyHessianServiceImpl implements MyHessianService {

[@Override](https://my.oschina.net/u/1162528)

public String justHadEnoughParties() {

System.out.println("task--------------->");

return "Please save me..";

}

[@Override](https://my.oschina.net/u/1162528)

public boolean checkLogin(User user) {

String username=user.getUsername();

String password=user.getPassword();

if(username.equals("tdw") && password.equals("123456")){

System.out.println("登录成功");

return true;

}

System.out.println("登录失败");

return false;

}

}

3.在主Application中注册一个HessianBean

@Autowired

MyHessianService myHessianService;

@Bean(name = "/myHessianService")

public HessianServiceExporter exportHelloService() {

HessianServiceExporter exporter = new HessianServiceExporter();

exporter.setService(myHessianService);

exporter.setServiceInterface(MyHessianService.class);

return exporter;

}

4.写一个服务端的项目，调用接口

关键点：

客户端需要调用服务端的服务，需要将服务端项目打包成jar

客户端引用jar文件，才能调用接口

客户端核心代码：

package com.useapi.hessionclient.Controller;

import com.caucho.hessian.client.HessianProxyFactory;

import com.ucardemo.asset.api.MyHessianService;

import com.ucardemo.asset.model.User;

import org.springframework.beans.factory.annotation.Autowired;

import org.springframework.web.bind.annotation.RequestMapping;

import org.springframework.web.bind.annotation.ResponseBody;

import org.springframework.web.bind.annotation.RestController;

import java.net.MalformedURLException;

@RestController

public class ClientController {

@RequestMapping("/xxxx")

@ResponseBody

public void test() throws MalformedURLException {

String url = "http://localhost:8081/myHessianService";

HessianProxyFactory factory = new HessianProxyFactory();

MyHessianService myHessianService = (MyHessianService) factory.create(MyHessianService.class, url);

User user=new User();

user.setPassword("123");

user.setUsername("123");

Boolean b= myHessianService.checkLogin(user);

System.out.println(b);

}

}
