springboot 整合dubbox 

1, 没了,,,

2, 安装zookeeper

可见: http://www.cnblogs.com/wenbronk/p/6636926.html

2.1 下载: 

wget http://mirrors.hust.edu.cn/apache/zookeeper/zookeeper-3.4.8/

解压: 

tar -zxf zookeeper-3.4.8.tar.gz

修改配置文件: 

  cd zookeeper-3.4.8/conf

  cp zoo_sample.cfg zoo.cfg # zookeeper 默认是用../conf/zoo.cfg 如果没有这个文件则报错

  vim zoo.cfg

其他, 能启动就行吧

  cd zookeeper-3.4.8/bin

  ./start.sh start #启动zookeeper 关闭: ./start.sh stop

我的zookeeper是安装在docker上的, 安装方式可见: http://www.cnblogs.com/wenbronk/p/6438492.html

3, maven工程

|--dubbo-prent                   父工程(pom)
|
|_____dubbo-cosumer              消费者(war)  
|
|_____duboo-provide              生产者(pom)
　　　　|
　　　　|_____interface        消费者和生产者都依赖这个, 一个接口, 实现rpc(jar)
　　　　|
　　　　|_____service　　　　　　　　实际的rpc调用的方法(war)

 其中interface 被 dubbo-consumer和service所依赖

4, parent 

parent主要用来统一管理使用的, 在其pom中进行jar包的统一依赖管理

pom.xml配置: 

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">

            </dependency>

        </dependencies>
    </dependencyManagement>
  
  
</project>

5, dubbo-provide, 这儿没什么用, 管理生产者和接口, 实际中还可以用来依赖统一的工具包等

pom.xml中没啥东西

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">

  <modules>
      <module>dubbo-provide-service</module>
      <module>dubbo-provide-interface</module>
  </modules>
</project>

6, interface: 

用来rpc调用的接口, 只有一个类: 

技术分享

TestService.java

package com.wenbronk.dubbo.service;

public interface TestService {
    
    public String test();
}

7, service

服务的生产者:

发布dubbo服务, 在application.properties中加入以下配置: 

server.port=8081

# Dubbo 消费者
spring.dubbo.application.name=provider
spring.dubbo.registry.address=zookeeper://192.168.50.202:2181
spring.dubbo.protocol.name=dubbo
spring.dubbo.protocol.port=20880
spring.dubbo.scan=com.wenbronk.dubbo

注意配置 scan的扫描路径

App.java

package com.wenbronk.dubbo;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

@SpringBootApplication
public class App {

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

 TestServiceImpl.java

package com.wenbronk.dubbo.service.impl;

import com.alibaba.dubbo.config.annotation.Service;
import com.wenbronk.dubbo.service.TestService;

@Service(version="1.0.0")
public class TestServiceImpl implements TestService {

    @Override
    public String test() {
        System.out.println("success");
        return "finally, i am coming";
    }
    
}

 

 8, 最后, 是cosumer

技术分享

pom.xml中配置, 同service中一样, 

application.properties

## 避免和 server 工程端口冲突
server.port=8080

## Dubbo 服务消费者配置
spring.dubbo.application.name=consumer
spring.dubbo.registry.address=zookeeper://192.168.50.202:2181
spring.dubbo.scan=com.wenbronk.dubbo

App.java 同service一样

TestController.java

package com.wenbronk.dubbo.controller;

import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

import com.alibaba.dubbo.config.annotation.Reference;
import com.wenbronk.dubbo.service.TestService;

@RestController
public class TestController {

    @Reference(version="1.0.0")
    private TestService testService;
    
    @RequestMapping("/abc")
    public String test() {
        System.out.println("controller.sucess");
        testService.test();
        return "success";
    }
    
}

 

 最初因为说dubbo-start不支持新的spring了, 所以下载了当当的dubbox自己编译, 后来发现, 还是可以用的

附: dubbox编译

dubbo, 阿里不维护了, 当当继续开源: 因为没有发布在仓库, 所以自己编译

git clone https://git.oschina.net/smarti/spring-boot-mybatis-sample.git

然后跳过test进行编译, 可以发布在本地仓库中

mvn install -Dmaven.test.skip=true

 

 

听说用注解的话, 不支持事物, 还没遇到, 遇到在更新
