整合（一）dubbo+zookeeper+springboot整合

女爷i 2022-05-31 00:10 323阅读 0赞

一、启动zookeeper，这里使用zookeeper单机模式，不用zookeeper集群

1、 解压修改zookeeper/conf里面的配置文件zoo\_sample.cfg为zoo.cfg

2、windows环境下启动zookeeper服务端，运行zkServer.cmd

3、启动zookeeper客户端,运行zkCli.cmd，可以用 “ls /”命令查看哪些服务被注册到了zookeeper

二、启动dubbo-admin

1、下载dubbo，这里使用老版本的，新版本使用方法后面讲[https://github.com/zhangai1989/dubbo.git][https_github.com_zhangai1989_dubbo.git]

首先运行dubbo-admin，它是一个web应用，用来方便查看dubbo的相关状态信息

2、修改配置文件信息，打开WEB-INF中的dubbo.properties

** **dubbo.registry.address ：zookeeper地址

dubbo.admin.root.password :root用户密码

dubbo.admin.guest.password :guest用户密码

3、打包部署

配置Project Structure

运行tomcat，然后访问地址，如下图所示则成功

三、在springboot项目中整合dubbo和zookeeper

使用前面创建好的springboot项目，项目地址[https://github.com/zhangai1989/sprintboot.git][https_github.com_zhangai1989_sprintboot.git]

1、引入dubbo和zookeeper相关的jar包依赖

<dependency>
                <groupId>com.alibaba</groupId>
                <artifactId>dubbo</artifactId>
                <version>2.4.10</version>
                <exclusions>
                    <exclusion>
                        <artifactId>spring</artifactId>
                        <groupId>org.springframework</groupId>
                    </exclusion>
                </exclusions>
            </dependency>
            <dependency>
                <groupId>org.apache.zookeeper</groupId>
                <artifactId>zookeeper</artifactId>
                <version>3.4.6</version>
                <exclusions>
                    <exclusion>
                        <artifactId>slf4j-log4j12</artifactId>
                        <groupId>org.slf4j</groupId>
                    </exclusion>
                </exclusions>
            </dependency>
            <dependency>
                <groupId>com.github.sgroschupf</groupId>
                <artifactId>zkclient</artifactId>
                <version>0.1</version>
            </dependency>

2、添加dubbo服务注册配置文件provider.xml  
![SouthEast 6][]

<?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">
        
        
        <dubbo:application name="dubbo-provider" owner="dubbo-provider"/>
        
        <dubbo:registry protocol="zookeeper" address="localhost:2181" client="zkclient"/>
        
        <dubbo:protocol name="dubbo" port="-1"/>
        
        <dubbo:service interface="com.jz.springbootdemo.producer.TestService" ref="testService" timeout="10000"/>
        
        <bean id="testService" class="com.jz.springbootdemo.producer.impl.TestServiceImpl" />
    </beans>

3、创建需要暴露的接口类TestService、TestServiceImpl

package com.jz.springbootdemo.producer.impl;
    
    import com.jz.springbootdemo.producer.TestService;
    
    public class TestServiceImpl implements TestService {
        @Override
        public String sayHello(String name) {
            return "Hello " + name + "!";
        }
    }

package com.jz.springbootdemo.producer;
    
    public interface TestService {
    
        String sayHello(String name);
    
    }

4、在SpringbootdemoApplication中添加将providers.xml添加到扫描中  
  
![SouthEast 7][]  
5、运行tomcat、在zkServer中  
 在zkclient中输入 ls / ; ls /dubbo查看zookeeper中注册成功的服务

![SouthEast 8][]

在dubbo-admin中查看dubbo服务信息

结语：dubbo+zookeeper+springboot整合完成，对于dubbo实现RPC远程调用后面详讲。
