SpringBoot集成Dubbo+zookeeper
本次搭建是分模块搭建,没下载zookeeper的先下了
---------小记一下
zookeeper及dubbo-admin下载地址：https://pan.baidu.com/s/1hXkoltcpqxj9ouzTTObRTw

创建SpringBoot项目:
创建完了之后的父pom.xml文件是这样:
<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

额,虽然是这个样子,但我还是修剪了一下,并且重新添加了几个依赖,变成了这样:

好了,现在父级的pom.xml已经处理完了,我们开始创建服务提供方:
我不喜欢用骨架,这个按个人喜好来:
完了之后可以看到父级的pom文件里已经把刚刚创建的模块自动添加到了里面:
那接下来开始将服务提供方给他弄完整(pom.xml就不用管了,直接拿他爹的来用):
写个接口:
package com.dubbo.service;
public interface DubboService {
String hello(String name);
}
写个实现类:
package com.dubbo.service.impl;
import com.alibaba.dubbo.config.annotation.Service; ← ← ← ← ←
import com.dubbo.service.DubboService; ↑
↑
@Service //这里这个注解看清楚了,导的是alibaba的包,别整错了 ↑↑
public class DubboServiceImpl implements DubboService {
@Override
public String hello(String name) {
return "hello--" + name;
}
}
springboot的启动类:
package com;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
@SpringBootApplication
public class Application {
public static void main(String[] args) {
SpringApplication.run(Application.class, args);
}
}
服务提供方目录结构如下图:
好了,这服务提供方代码就写完了,下来把resources下的application.yml给他一配就完事了:
server:
port: 8081 #那傻猫的端口号
spring:
dubbo:
application:
name: springboot-dubbo-tgz #提供方名字 不能与消费方相同
registry:
address: zookeeper://localhost #zookeeper的地址
port: 2181 #注册的端口
protocol:
name: dubbo
port: 20890 #dubbo服务暴露的端口
scan: com.dubbo.service.impl #扫描需要暴露的服务
现在直接启动服务提供方Application,打开dubbo的控制台: http://localhost:8080/dubbo-admin-2.6.0,可以看到:
你要是没看到的话,我也不知道咋回事,自己检查吧!!!
至此,服务提供方已经搞定了,现在开始整服务消费方,消费方模块创建我就不贴图了,方法同上:
把提供方接口贴过来,包名给我整对咯!:
package com.dubbo.service;
public interface DubboService {
String hello(String name);
}
写个controller:
package com.dubbo.controller;
import com.alibaba.dubbo.config.annotation.Reference; ← ← ←
import com.dubbo.service.DubboService; ↑
import org.springframework.stereotype.Controller; ↑
import org.springframework.web.bind.annotation.RequestMapping; ↑
import org.springframework.web.bind.annotation.ResponseBody; ↑
↑
@Controller ↑
@RequestMapping("/hello") ↑
public class DubboController {
↑
@Reference //这里注意了,是alibaba的包,导包的时候看清楚了 ↑↑↑
private DubboService dubboService;
@RequestMapping("/visitHello")
@ResponseBody
public String visitHello(String name){
return dubboService.hello(name);
}
}
服务消费方目录结构如下:
好了,服务消费方配置文件搞一下,就完事了,这边的配置比服务提供方要少,少些啥就不赘述了:
server:
port: 8082 #猫的端口
spring:
dubbo:
application:
name: springboot-dubbo-xfz #消费方名字 不能与提供方相同
registry:
address: zookeeper://localhost #zookeeper的地址
port: 2181 #注册的端口
scan: com.dubbo.controller #包扫描
启动服务消费方Application,打开控制台查看:
好了,经过一顿操作,这俩齐活了,现在通过消费方访问提供方,看能不能调到提供方的接口:
http://localhost:8082/hello/visitHello?name=你连不连的通?
好了,连上了
至此,我这笔记就写到这里了,写完,收工
写在最后:
人若成就一道景致,则无关春夏秋冬.
