【Spring Cloud】一、Eureka Server 服务注册中心服务端启动

建立maven工程

工程结构如下：

pom文件如下：

其中注意spring-boot-starter-parent和spring-boot-starter-parent的版本号要对应起来，否则运行可能报错，楼主踩过坑

配置文件中重要配置项如下：

#是否向服务注册中心注册自己
eureka.client.register-with-eureka=false
#是否检索服务
eureka.client.fetch-registry=false
#服务注册中心实例的主机名
eureka.instance.hostname=myinstance


logging.level.com.netflix.eureka=OFF
logging.level.com.netflix.discovery=OFF


#服务注册中心端口号
server.port=23456

启动代码如下：

package com.chiwei.eureka;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.cloud.netflix.eureka.server.EnableEurekaServer;

/**
 * @Type Bootstrap.java
 * @Desc 
 * @author chiwei
 * @date 2017年11月9日 下午5:24:53
 * @version 
 */
/**
 * @author chiwei
 *
 */

@EnableEurekaServer
@SpringBootApplication
public class Bootstrap {

    /**
     * 主函数入口
     * @param args
     */
    public static void main(String[] args) {
        SpringApplication app = new SpringApplication(Bootstrap.class);
        // 不启动web服务
        // app.setWebEnvironment(false);
        app.run(args);
    }

}

启动服务注册中心服务端

至此，eureka的服务注册中服务端启动成功了。
