SpringCloud整合Zookeeper代替Eureka
注册中心Zookeeper
1、关闭Linux服务器防火墙后启动zookeeper服务器（客户端和服务端都要启动）
2、zookeeper服务器取代Eureka服务器，zk作为服务注册中心
服务提供者
1、新建cloud-provider-payment8004
2、改POM
<dependencies>
<dependency>
<groupId>com.sl.springcloud</groupId>
<artifactId>cloud-api-commons</artifactId>
<version>${project.version}</version>
</dependency>
<!-- https://mvnrepository.com/artifact/org.springframework.boot/spring-boot-starter-web -->
<dependency>

</dependency>

<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-devtools</artifactId>
<scope>runtime</scope>
<optional>true</optional>
</dependency>

<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-test</artifactId>
<scope>test</scope>
</dependency>
</dependencies>
3、写yml
server:
port: 8004
spring:
application:
name: cloud-provider-payment
cloud:
zookeeper:
connect-string: 192.168.136.140:2181
4、主启动类
@SpringBootApplication
@EnableDiscoveryClient
public class PaymentMain8004 {
public static void main(String[] args) {
SpringApplication.run(PaymentMain8004.class,args);
}
}
5、Controller
@RestController
@Slf4j
public class PaymentController {
@Value("${server.port}")
private String serverPort;
@GetMapping(value = "/payment/zk")
public String paymentzk(){
return "springcloud with zookeeper:"+serverPort+"\t"+ UUID.randomUUID().toString();
}
}
6、 启动8004注册进zookeeper
启动后问题：
原因：zookeeper版本jar包冲突问题
解决： 更新POM
<dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-starter-zookeeper-discovery</artifactId>
<!--排除zk3.5.3-->
<exclusions>
<exclusion>
<groupId>org.apache.zookeeper</groupId>
<artifactId>zookeeper</artifactId>
</exclusion>
</exclusions>
</dependency>
<!--添加zk 3.4,9版本-->
<!-- https://mvnrepository.com/artifact/org.apache.zookeeper/zookeeper -->
<dependency>
<groupId>org.apache.zookeeper</groupId>
<artifactId>zookeeper</artifactId>
<version>3.4.9</version>
</dependency>
测试
1、http://localhost:8004/payment/zk
2、在Zookeeper客户端
获得json串后可以用json串解析工具看一下
服务消费者
1、新建cloud-consumerzk-order80
2、改pom
<dependencies>
<dependency>
<groupId>com.atguigu.springcloud</groupId>
<artifactId>cloud-api-commons</artifactId>
<version>${project.version}</version>
</dependency>
<!-- https://mvnrepository.com/artifact/org.springframework.boot/spring-boot-starter-web -->
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-web</artifactId>
</dependency>
<!-- https://mvnrepository.com/artifact/org.springframework.boot/spring-boot-starter-web -->
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-actuator</artifactId>
</dependency>
<!-- https://mvnrepository.com/artifact/org.springframework.cloud/spring-cloud-starter-zookeeper-discovery -->
<dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-starter-zookeeper-discovery</artifactId>
</dependency>
<!-- https://mvnrepository.com/artifact/org.springframework.boot/spring-boot-devtools -->
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-devtools</artifactId>
<scope>runtime</scope>
<optional>true</optional>
</dependency>
<!-- https://mvnrepository.com/artifact/org.projectlombok/lombok -->
<dependency>
<groupId>org.projectlombok</groupId>
<artifactId>lombok</artifactId>
<optional>true</optional>
</dependency>
<!-- https://mvnrepository.com/artifact/org.springframework.boot/spring-boot-starter-test -->
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-test</artifactId>
<scope>test</scope>
</dependency>
</dependencies>
3、写yml
server:
port: 80
spring:
application:
name: cloud-consumer-order
cloud:
zookeeper:
connect-string: 192.168.80.33:2181
4、主启动
@SpringBootApplication
@EnableDiscoveryClient
public class OrderZKMain80 {
public static void main(String[] args) {
SpringApplication.run(OrderZKMain80.class,args);
}
}
5、业务类
①配置Bean
@Configuration
public class ApplicationContextConfig {
@LoadBalanced
@Bean
public RestTemplate getRestTemplate(){
return new RestTemplate();
}
}
②Controller
@RestController
@Slf4j
public class OrderZKController {
public static final String INVOME_URL = "http://cloud-provider-payment";
@Resource
private RestTemplate restTemplate;
@GetMapping("/consumer/payment/zk")
public String payment (){
String result = restTemplate.getForObject(INVOME_URL+"/payment/zk",String.class);
return result;
}
}
6、启动80注册进zookeeper（启动会有问题，还是依赖问题，按照服务提供者的解决方案就可以）
验证测试
1、http://localhost:8004/payment/zk
2、访问测试地址：http://localhost/consumer/payment/zk
