​

 1、在Linux中配置zookeeper

1）解压到安装到 /opt/module 下

2）进入zookeeper

3）进入conf

4）执行：

cp zoo_sample.cfg zoo.cfg

vim zoo.cfg

修改

​

5）改成自己的目录

6）之后修改 /etc/profile中的信息

​

 2、运行

进入到 zookeeper/bin目录下

zkServer.sh start  

zkServer.sh status 查看状态

3、配置springcloud-zookeeper-provider-9003

}

启动类：

@SpringBootApplication
@EnableDiscoveryClient
public class Zookeeper9003 {
    public static void main(String[] args) {
        SpringApplication.run(Zookeeper9003.class,args);
    }
}

4、配置consumer中的zookeeper

​

pom.xml文件：

    <dependencies>
        <dependency>
            <groupId>org.example</groupId>
            <artifactId>springcloud-api</artifactId>

            <exclusions>
                <exclusion>
                    <groupId>tk.mybatis</groupId>
                    <artifactId>mapper-spring-boot-starter</artifactId>

                </exclusion>
            </exclusions>
        </dependency>


        <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-starter-zookeeper-discovery</artifactId>
            <exclusions>
                <exclusion>

                    <artifactId>zookeeper</artifactId>
                </exclusion>
            </exclusions>
        </dependency>

        <dependency>
            <groupId>org.apache.zookeeper</groupId>
            <artifactId>zookeeper</artifactId>
            <version>3.4.11</version>
            <exclusions>
                <exclusion>
                    <groupId>org.slf4j</groupId>
                    <artifactId>slf4j-log4j12</artifactId>
                </exclusion>
            </exclusions>
        </dependency>

    </dependencies>

配置：

server:
  port: 9004
spring:
  application:
    name: zookeeper-consumer-9004
  cloud:
    zookeeper:
      connect-string: ip:port #配置zookeeper的端口号与ip

import org.springframework.cloud.client.loadbalancer.LoadBalanced;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.web.client.RestTemplate;

@Configuration
public class ApplicationConfig {

    @Bean
    @LoadBalanced
    public RestTemplate getRestTemplate(){
        return new RestTemplate();
    }


}

UserController

@RestController
@RequestMapping("/user")
public class UserController {

    @Autowired
    private RestTemplate restTemplate;

    private static final String REST_URL="http://springcloud-zookeeper-provider-9003";

    @RequestMapping("/getAll")
    public Object getAll(){
        ResponseEntity<Object> forEntity = restTemplate.getForEntity(REST_URL + "/movie/getAll", Object.class);
        return forEntity;
    }

    @RequestMapping("/get/{id}")
    public Object getOne(@PathVariable("id") Integer id){
        ResponseEntity<Object> forEntity = restTemplate.getForEntity(REST_URL + "/movie/getOne/"+id, Object.class);
        return forEntity;
    }


}

启动类：

@SpringBootApplication
@EnableDiscoveryClient
public class Zookeeper9004 {
    public static void main(String[] args) {
        SpringApplication.run(Zookeeper9004.class,args);
    }
}

5、启动

​

 正常！！！
