springboot集成dubbo(详细配置)

前言:

首先要搭建zookeeper环境并启动,可参照window下搭建zookeeper_半生归来仍少年的博客-CSDN博客

dubbo管理平台搭建:

下载:dubbo-admin-2.5.8.war-互联网文档类资源-CSDN下载

放到tomcat的webapp目录下,注意zookeeper的端口要对应(WEB-INFdubbp.application),启动tomcat访问,账号密码好像是 root/root 或者是guest/guest

1.新建项目dubboapi(接口服务)

 1.1.说明:该项目是存放调用的接口

项目结构大致如下

1.2.pom文件如下

    4.0.0
    
        org.springframework.boot
        spring-boot-starter-parent
        2.5.6
         
    
    com.example
    dubboapi
    0.0.1-SNAPSHOT
    jar
    dubboapi
    Demo project for Spring Boot
    
        1.8
    
    
        
            org.springframework.boot
            spring-boot-starter
        

        
            org.springframework.boot
            spring-boot-starter-test
            test
        
    

    
        
            
                org.springframework.boot
                spring-boot-maven-plugin
            
        
    

1.3.baseService类如下

package com.example.dubboapi.service;

public interface baseService {
    String test(String name);

    String test();
}

2.新建项目dubboprovider(接口提供者)

2.1.说明:给消费者提供接口调用

项目目录大致如下

3.新建项目dubboconsumer(接口消费者)

3.1.说明:调用接口提供者的接口

目录大致如下

 4.在dubboapi(接口服务)项目将dubboprovider(接口提供者)和dubboconsumer(接口消费者)作为模块引入

4.1.操作如下:

 

4.1.以上操作将 dubboprovider(接口提供者)和dubboconsumer(接口消费者)引入进来,此时目录结构大致如下:

 5.配置dubboprovider(接口提供者)

5.1.pom文件配置如下,注意一定要引入dubboapi(接口服务)

    4.0.0
    
        org.springframework.boot
        spring-boot-starter-parent
        2.5.6
         
    
    com.example
    dubboprovider
    0.0.1-SNAPSHOT
    jar
    dubboprovider
    Demo project for Spring Boot
    
        1.8
    
    
        
            org.springframework.boot
            spring-boot-starter
        

        
            org.springframework.boot
            spring-boot-starter-test
            test
        
        
        
            com.example
            dubboapi
            0.0.1-SNAPSHOT
            compile
        
        
        
            com.alibaba.boot
            dubbo-spring-boot-starter
            0.2.0
        
    

    
        
            
                org.springframework.boot
                spring-boot-maven-plugin
            
        
    

5.2.在service目录下新建UserServiceImpl并实现baseService接口,注意:是使用dubbo的@service注解

package com.example.dubboprovider.service;

import com.alibaba.dubbo.config.annotation.Service;
import com.example.dubboapi.service.baseService;

@Service
public class UserServiceImpl implements baseService {
    @Override
    public String test(String name) {
        return name+">--<";
    }

    @Override
    public String test() {
        return "测试测试";
    }
}

5.3.在启动类加上@EnableDubbo

package com.example.dubboprovider;

import com.alibaba.dubbo.config.spring.context.annotation.EnableDubbo;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
@EnableDubbo
@SpringBootApplication
public class DubboproviderApplication {

    public static void main(String[] args) {
        SpringApplication.run(DubboproviderApplication.class, args);
    }

}

5.4.application.yml配置如下

dubbo:
  application:
    name: dubbo-provider
  registry:
    address: 127.0.0.1:2181
    protocol: zookeeper
    check: false
  protocol:
    name: dubbo
    port: 22222
  monitor:
    protocol: register
  consumer:
    check: false
    timeout: 3000
server:
  port: 9998

 5.5.启动启动类

在dubbo的管理平台能 能看到接口的信息

 6.配置dubboconsumer(接口消费者)

6.1.pom文件配置如下,注意一定要引入dubboapi(接口服务)

    4.0.0
    
        org.springframework.boot
        spring-boot-starter-parent
        2.5.6
         
    
    com.example
    dubboconsumer
    0.0.1-SNAPSHOT
    jar
    dubboconsumer
    Demo project for Spring Boot
    
        1.8
    
    
        
            org.springframework.boot
            spring-boot-starter
        

        
            org.springframework.boot
            spring-boot-starter-test
            test
        

        
        
            com.example
            dubboapi
            0.0.1-SNAPSHOT
            compile
        

        
        
            com.alibaba.boot
            dubbo-spring-boot-starter
            0.2.0
        
        
            org.springframework.boot
            spring-boot-starter-web
        
    

    
        
            
                org.springframework.boot
                spring-boot-maven-plugin
            
        
    

6.2.编写service和controller代码

6.2.1.service层,注意这里的@Service是spring的注解了,@Reference注入的是分布式的远程服务的对象

public interface UserService {
    String test(String name);

    String test();
}

package com.example.dubboconsumer.service;

import com.alibaba.dubbo.config.annotation.Reference;
import com.example.dubboapi.service.baseService;
import org.springframework.stereotype.Service;

@Service
public class UserServiceImpl implements UserService{
    @Reference
    private baseService userService;

    @Override
    public String test(String name) {
        return userService.test(name);
    }

    @Override
    public String test() {
        return userService.test();
    }
}

6.2.2.controller层

package com.example.dubboconsumer.controller;

import com.example.dubboconsumer.service.UserService;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

import javax.annotation.Resource;

@RestController
public class UserController {
    @Resource
    private UserService userService;

    @RequestMapping("/test1")
    public String test(){
        return userService.test("测试测试测试测试");
    }

    @RequestMapping("/test2")
    public String test1(){
        return userService.test();
    }
}

6.3.启动类加上@EnableDubbo

@EnableDubbo
@SpringBootApplication
public class DubboconsumerApplication {

    public static void main(String[] args) {
        SpringApplication.run(DubboconsumerApplication.class, args);
    }

}

6.4.配置application.yml

dubbo:
  application:
    name: dubbo-consumer
  registry:
    address: 127.0.0.1:2181
    protocol: zookeeper
    check: false
  monitor:
    protocol: register
  consumer:
    check:  false
    timeout: 3000

server:
  port: 9999

6.5.启动启动类

 在dubbo的管理平台能 能看到接口的信息

 6.6.浏览器访问127.0.0.1:9999/test1 和127.0.0.1:9999/test2

 接口调用正常
