spring boot集成dubbo实现rpc调用
dubbo官网： http://dubbo.apache.org
dubbo github 源码地址：https://github.com/apache/incubator-dubbo
dubbo 运维项目源码地址：https://github.com/apache/incubator-dubbo-ops
首先，zookeeper的安装过程省略，方法翻看以往博客！！！
其次，新建一个maven空项目，然后在此空项目内新建3个module，分别为numberone（服务提供方的纯接口项目），allnumberone（服务消费方）,one（服务提供方的接口具体实现项目）。
新建maven空项目方法略。
一：numberone项目代码：
public interface Cost {
/**
* 增加接口
* @return
*/
Integer add(Integer a);
}以及maven依赖

二：服务消费项目代码：
接口：
package com.example.demo.service;
public interface GetProduct {
/**
* 获得总消费
* @return
*/
Integer getCost(Integer a);
}
实现类：
package com.example.demo.service.impl;
import com.alibaba.dubbo.config.annotation.Reference;
import com.alibaba.dubbo.config.annotation.Service;
import com.example.demo.service.Cost;
import com.example.demo.service.GetProduct;
@Service
public class GetProImpl implements GetProduct {
@Reference
private Cost costService;
@Override
public Integer getCost(Integer a) {
return costService.add(a);
}
}
controller：
package com.example.demo.controller;
import com.example.demo.service.GetProduct;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;
@RestController
public class ProController {
@Autowired
private GetProduct getProduct;
@RequestMapping("/add")
public String getCost(Integer a){
return "该产品总共消费 ："+getProduct.getCost(a);
}
}
依赖pom：
