springcloud-支付服务入驻zookeeper

之前采用的注册中心是eureka，现在换成zookeeper，我们重新创建一个模块来演示，嗯，来吧。

　　1.创建支付模块8004

　　2.引入依赖

    <dependencies>
        <dependency>
            <groupId>cn.aib.springcloud</groupId>
            <artifactId>springclud-api-common</artifactId>
            <version>1.0-SNAPSHOT</version>
        </dependency>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-web</artifactId>
        </dependency>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-actuator</artifactId>
        </dependency>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-test</artifactId>
            <scope>test</scope>
        </dependency>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-devtools</artifactId>
            <scope>runtime</scope>
            <optional>true</optional>
        </dependency>
        <dependency>
            <groupId>org.projectlombok</groupId>
            <artifactId>lombok</artifactId>
            <optional>true</optional>
        </dependency>
        <!--   引入zookeeper客户端     -->
        <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-starter-zookeeper-discovery</artifactId>
            <exclusions>
                <exclusion>
                    <groupId>org.apache.zookeeper</groupId>
                    <artifactId>zookeeper</artifactId>
                </exclusion>
            </exclusions>
        </dependency>
        <dependency>
            <groupId>org.apache.zookeeper</groupId>
            <artifactId>zookeeper</artifactId>
            <version>3.4.13</version>
        </dependency>

    </dependencies>

　　在上面的依赖种，我要说明一点：其中我们引入springcloud zookeeper的依赖，它底层还依赖属于zookeeper本身的jar包，如果你zookeeper服务器的版本和它自带的版本不一致，则会版本冲突的问题，我的zookeeper是3.4.13，所以把它自带给排出去了，用对应版本的zookeeper依赖。

　　3.改配置

server:
  port: 8004

# 服务别名---zookeeper注册中心名称
spring:
  application:
    name: cloud-provider-payment
  cloud:
    zookeeper:
      connect-string: 192.168.xx.xxx:2181

　　4.主启动

@SpringBootApplication
@EnableDiscoveryClient
public class PaymentApplication8004 {

    public static void main(String[] args) {
        SpringApplication.run(PaymentApplication8004.class, args);
    }
}

　　eureka那个注解就不再需要了，但是@EnableDdiscoveryClient一定得有，好几个注册中心都需要用到这个注解来保证服务注册到注册中心里

　　5.业务类

@RestController
@Slf4j
public class PaymentController {

    @Value("${server.port}")
    private String serverPort;

    @RequestMapping(value = "/payment/zk")
    public String paymentzk(){
        return "springcloud with zookeeper: " + serverPort + "\t" + UUID.randomUUID().toString();
    }

}

　　6.测试；启动该模块，然后到linux的服务器查看，如下：
