SpringBoot整合Dubbo+Zookeaper

1.安装运行zookeeper

（1）下载zookeeper

官网：http://zookeeper.apache.org/

（2）解压缩

（3）修改配置文件

  1. 拷贝zoo_sample.cfg重命名为zoo.cfg

  2. 修改配置文档

    # The number of milliseconds of each tick
    tickTime=2000
    # The number of ticks that the initial 
    # synchronization phase can take
    initLimit=10
    # The number of ticks that can pass between 
    # sending a request and getting an acknowledgement
    syncLimit=5
    # the directory where the snapshot is stored.
    # do not use /tmp for storage, /tmp here is just 
    # example sakes.
    dataDir=../data
    # the port at which the clients will connect
    clientPort=2181
    # the maximum number of client connections.
    # increase this if you need to handle more clients
    #maxClientCnxns=60
    #
    # Be sure to read the maintenance section of the 
    # administrator guide before turning on autopurge.
    #
    # http://zookeeper.apache.org/doc/current/zookeeperAdmin.html#sc_maintenance
    #
    # The number of snapshots to retain in dataDir
    #autopurge.snapRetainCount=3
    # Purge task interval in hours
    # Set to "0" to disable auto purge feature
    #autopurge.purgeInterval=1

  3. 创建data文件夹

（4）cmd启动zkServer.sh

2.安装dubbo web管理客户端

（1）下载Duboo OPS

下载地址：https://github.com/apache/incubator-dubbo-ops/tree/master

（2）修改配置

4.整合springboot

（1）新建Maven项目：d_api ：一个公用service的api

  1. 新建一个接口：HelloService

    package com.xm.dubbo.service;
    public interface HelloService {
    	String sayHello();
    }

（2）新建Springboot项目：Hello_Producer

参考链接：https://github.com/apache/incubator-dubbo-spring-boot-project

  1. 添加依赖

    <?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"

    				<artifactId>spring-boot-maven-plugin</artifactId>
    			</plugin>
    		</plugins>
    	</build>
    </project>

  2. 修改配置文件

    dubbo.application.name=hello_producer
    dubbo.registry.protocol=zookeeper
    dubbo.registry.address=127.0.0.1:2181
    dubbo.scan.base-packages=com.xm.dubbo.service
    dubbo.protocol.name=dubbo
    dubbo.protocol.port=20080
    dubbo.monitor.protocol=registry

  3. 新建HelloServiceImpl

    package com.xm.dubbo.service.impl;
    import org.springframework.stereotype.Component;
    import com.alibaba.dubbo.config.annotation.Service;
    import com.xm.dubbo.service.HelloService;
    @Service
    @Component
    public class HelloServiceImpl implements HelloService {
    	@Override
    	public String sayHello() {
    		System.out.println("生产者已被调用！");
    		return "Hello dubbo!";
    	}
    }

  4. 项目入口添加@EnableDubbo注解

    package com.xm.dubbo;
    import org.springframework.boot.SpringApplication;
    import org.springframework.boot.autoconfigure.SpringBootApplication;
    import com.alibaba.dubbo.config.spring.context.annotation.EnableDubbo;
    @EnableDubbo
    @SpringBootApplication
    public class HelloProducerApplication {
    	public static void main(String[] args) {
    		SpringApplication.run(HelloProducerApplication.class, args);
    	}
    }

（3）新建Springboot项目：Hello_Consumer

  1. 添加依赖

    <?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"

    				<artifactId>spring-boot-maven-plugin</artifactId>
    			</plugin>
    		</plugins>
    	</build>
    </project>

  2. 修改配置文件

    server.port=8081
    dubbo.application.name=hello_consumer
    dubbo.registry.protocol=zookeeper
    dubbo.registry.address=127.0.0.1:2181
    dubbo.monitor.protocol=registry

  3. 新建HelloController

    package com.xm.dubbo.controller;
    import org.springframework.web.bind.annotation.GetMapping;
    import org.springframework.web.bind.annotation.RestController;
    import com.alibaba.dubbo.config.annotation.Reference;
    import com.xm.dubbo.service.HelloService;
    @RestController
    public class HelloController {
    	@Reference
    	private HelloService helloService;
    	@GetMapping("/hello")
    	public String sayHello() {
    		return helloService.sayHello();
    	}
    }

  4. 项目入口添加@EnableDubbo注解

    package com.xm.dubbo;
    import org.springframework.boot.SpringApplication;
    import org.springframework.boot.autoconfigure.SpringBootApplication;
    import com.alibaba.dubbo.config.spring.context.annotation.EnableDubbo;
    @EnableDubbo
    @SpringBootApplication
    public class HelloConsumerApplication {
    	public static void main(String[] args) {
    		SpringApplication.run(HelloConsumerApplication.class, args);
    	}
    }
