**一 pom**

         </build>
    </project>

**二 启动类**

package org.fkit.devtoolstest;
    
    
    import org.springframework.boot.SpringApplication;
    import org.springframework.boot.autoconfigure.SpringBootApplication;
    
    
    @SpringBootApplication
    public class App
    {
        public static void main( String[] args )
        {
            SpringApplication.run(App.class, args);
        }
    }

**三 控制器**

1 HelloController

package org.fkit.devtoolstest.controller;
    import org.springframework.web.bind.annotation.RequestMapping;
    import org.springframework.web.bind.annotation.RestController;
    @RestController
    public class HelloController {
        
        @RequestMapping("/hello")
        public String hello(){
            System.out.println("测试spring-boot-devtools热部署");
            return "hello,devtools.....!";
        }
        
    }

2 HelloController2

package org.fkit.devtoolstest.controller;
    import org.springframework.web.bind.annotation.RequestMapping;
    import org.springframework.web.bind.annotation.RestController;
    @RestController
    public class HelloController2 {
        
        @RequestMapping("/hellonew")
        public String hello(){
            System.out.println("测试spring-boot-devtools new热部署");
            return "hellonew,devtools new.....!";
        }
        
    }

**四 配置文件**

server.port=8080

**五 测试**

修改类文件或配置文件，系统都会热重启。
