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;
    }
}
