Spring Cloud之二 微服务注册

1：Intellij 新建服务 user-service

2：pom.xml

3:启动类

package cn.tigee;import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.cloud.client.discovery.EnableDiscoveryClient;@SpringBootApplication
@EnableDiscoveryClient
public class ApplicationMain {static final Logger logger = LoggerFactory.getLogger(ApplicationMain.class);public static void main(String[] args) {logger.debug("服务启动..start......");SpringApplication.run(ApplicationMain.class, args);logger.debug("服务启动..end......");}}

4：application.xml

package cn.tigee;import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.cloud.client.discovery.EnableDiscoveryClient;@SpringBootApplication
@EnableDiscoveryClient
public class ApplicationMain {static final Logger logger = LoggerFactory.getLogger(ApplicationMain.class);public static void main(String[] args) {logger.debug("服务启动..start......");SpringApplication.run(ApplicationMain.class, args);logger.debug("服务启动..end......");}}

5:restfull 接口

package cn.tigee.controller;import org.springframework.beans.factory.annotation.Value;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;@RestController
public class HelloController {@Value("${server.port}")private int port;@Value("${spring.application.name}")private String serve;@RequestMapping("hello")public String hello(){return "你好:"+serve+":"+port;}
}

6：启动

7：访问 localhost:7003/hello?name=12

8：查看注册中心
