dubbo 2.6.2 + zookeeper 3.4.13 + SpringBoot 2.0.5 搭建

代码地址 :https://github.com/xingxingtx/SpringBoot.git

gitclone：[email protected]:xingxingtx/SpringBoot.git

代码大致结构如下图：

 创建工程名为：

• springboot-dubbo-provide  工程用于提供服务。
• springboot-dubbo-api  工程主要是放一些service接口，用于提供给消费者使用 。
• springboot-dubbo-consume 工程为消费者。

dubbo-admin 安装

参考地址 可以自己百度怎么安装   这里分享一个war包：百度网盘地址 密码：dvq4

工程创建

注意在启动类上添加

@EnableDubboConfig 注解

springboot-dubbo-provide

pom.xml  与

springboot-dubbo-consume pom.xml也是同样引入

 ProvideConfig配置

package com.provide.config;

import com.alibaba.dubbo.config.ApplicationConfig;
import com.alibaba.dubbo.config.ProtocolConfig;
import com.alibaba.dubbo.config.RegistryConfig;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.context.annotation.ImportResource;

/**
 * Created by Administrator on 2018/11/7.
 */
@Configuration
@ImportResource({ "classpath:dubbo/*.xml" })
public class ProvideConfig {

}

UserServiceImpl：

Service是dubbo的注解别引错

package com.provide.impl;

import com.alibaba.dubbo.config.annotation.Service;
import com.api.model.user.UserModel;
import com.api.service.UserService;
import org.springframework.stereotype.Component;

/**
 * Created by Administrator on 2018/11/7.
 */
@Service(version = "1.0")
@Component
public class UserServiceImpl implements UserService {
    @Override
    public void insertUser(UserModel model) {
        //相关处理
    }
}

springboot-dubbo-consume

pom.xml 与springboot-dubbo-provide一样

dubbo-consume.xml

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:dubbo="http://code.alibabatech.com/schema/dubbo"
       xsi:schemaLocation="http://www.springframework.org/schema/beans
	http://www.springframework.org/schema/beans/spring-beans.xsd
	http://code.alibabatech.com/schema/dubbo
	http://code.alibabatech.com/schema/dubbo/dubbo.xsd">

    <!-- 应用配置，用于配置当前应用信息，不管该应用是提供者还是消费者。 -->
    <dubbo:application name="example-consume" />

    <!-- 注册中心暴露服务地址 -->
    <dubbo:registry id="zookeeper" protocol="zookeeper" address="localhost:2181" />

    <!-- 使用注解方式-->
    <dubbo:annotation package="com.consume"/>


    <!--引用服务配置，用于创建一个远程服务代理，一个引用可以指向多个注册中心。 引用com.api.service.UserService服务-->
    <dubbo:reference id="userService" interface="com.api.service.UserService"
                     check="false" version="1.0" registry="zookeeper" protocol="dubbo" timeout="15000"/>
</beans>

Controller调用：

package com.consume.controller.order;

import com.api.model.user.UserModel;
import com.consume.service.OrderService;
import io.swagger.annotations.Api;
import io.swagger.annotations.ApiOperation;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.RestController;

/**
 * Created by Administrator on 2018/11/7.
 */

@RestController
@Api("用户模块")
public class OrderController {
    @Autowired
    OrderService orderService;
    @RequestMapping(value = "/api/user",method = RequestMethod.GET)
    @ApiOperation(value = "用户模块新增", httpMethod = "GET", response = String.class, notes = "用户模块新增，提供用户管理-用户模块新增操作")
    public String insertUser(){
        UserModel model = new UserModel();
        model.setUserName("haha123");
        model.setAddress("怀化");
        orderService.insertUser(model);
        return model.toString();
    }
}

service：

@Reference dubbo注解  属于直连的方式 

package com.consume.service.impl;

import com.alibaba.dubbo.config.annotation.Reference;
import com.api.model.user.UserModel;
import com.api.service.UserService;
import com.consume.service.OrderService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;

/**
 * Created by Administrator on 2018/11/9.
 */
@Service
public class OrderServiceImpl implements OrderService{
    @Reference(version = "1.0")
    UserService userService;
    @Override
    public void insertUser(UserModel model) {
        userService.insertUser(model);
    }
}

springboot-dubbo-api  比较简单 代码就不贴出  截图如下，实体类一定要实现Serializable接口

---

启动:

首先下载对应项目版本的zookeeper  此项目为3.4.13 zookeeper安装请自行百度

这里分享一个3.4.13版本的zookeeper  百度网盘地址 密码：t5yu

1.启动zookeeper服务

2.启动dubbo-admin

3.启动springboot-dubbo-consume

4.启动springboot-dubbo-provide

5.打开地址http://localhost:8080/dubbo-admin-2.5.6/ 如下图表示基础框架搭建已经完成。

提供者界面：

消费者界面：
