我愛java系列---【springboot項目集成zookeeper作為注冊中心】

1.引入maven依賴

    <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-starter-zookeeper-discovery</artifactId>
            <version>2.1.1.RELEASE</version>
            <exclusions>
                <exclusion>
                    <groupId>org.apache.zookeeper</groupId>
                    <artifactId>zookeeper</artifactId>
                </exclusion>
            </exclusions>
        </dependency>
        <dependency>
            <groupId>org.apache.zookeeper</groupId>
            <artifactId>zookeeper</artifactId>
            <!-- 與服務器安裝的Zookeeper版本相同 -->
            <version>3.4.6</version>
            <exclusions>
                <exclusion>
                    <groupId>org.slf4j</groupId>
                    <artifactId>slf4j-log4j12</artifactId>
                </exclusion>
            </exclusions>
        </dependency>

上面的依賴放到<dependencies>標簽中，下面的放到<dependencies>標簽同級目錄中

    <!--SpringCloud所有依賴管理的坐標-->
    <dependencyManagement>
        <dependencies>
            <dependency>
                <groupId>org.springframework.cloud</groupId>
                <artifactId>spring-cloud-dependencies</artifactId>
                <version>Greenwich.SR1</version>
                <type>pom</type>
                <scope>import</scope>
            </dependency>
        </dependencies>
    </dependencyManagement>

2.在springboot啟動類上加上注解：@EnableDiscoveryClient

3.在yml中加上配置

spring:
  application:
    #本地測試
    name: dblocalhost
    #測試服務器
    #name: db201
  cloud:
    zookeeper:
      connect-string: 190.7.18.193:2181
      #connect-string: localhost:2181
      discovery:
        enabled: true
        register: true
        instance-host: ${spring.cloud.client.ip-address}  //自動獲取啟動服務的ip注冊到zk注冊中心
        #instance-host: 180.8.16.47   //也可以寫死，建議寫上面的那種用法
        root: /sms  //注冊到zk之后的根節點的名稱
