spring boot集成dubbo實現rpc調用

dubbo官網： http://dubbo.apache.org
dubbo github 源碼地址：https://github.com/apache/incubator-dubbo
dubbo 運維項目源碼地址：https://github.com/apache/incubator-dubbo-ops

 

首先，zookeeper的安裝過程省略，方法翻看以往博客！！！

其次，新建一個maven空項目，然後在此空項目內新建3個module，分別爲numberone（服務提供方的純接口項目），allnumberone（服務消費方）,one（服務提供方的接口具體實現項目）。

新建maven空項目方法略。

一：numberone項目代碼：

public interface Cost {

        /**
         * 增加接口
         * @return
         */
        Integer add(Integer a);
}

以及maven依賴

		</plugins>
	</build>

</project>

二：服務消費項目代碼：

接口：

package com.example.demo.service;

public interface GetProduct {

    /**
     * 獲得總消費
     * @return
     */
    Integer getCost(Integer a);
}

實現類：

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 "該產品總共消費 ："+getProduct.getCost(a);
    }

}

四：完成以上操作後，啓動allnumberone(服務消費)項目，以及one（服務提供方實現類）項目，在瀏覽器中訪問 http://localhost:8062/add?a=100
