每次修改代码都要重启服务器的痛，别说你不懂。

一、环境

• IntelliJ IDEA 2017.1.4 x64

二、SpringBoot 配置

 
 

   
   

    
    

   
   
   
   

    
    

     
      <dependency>
    
    
   
   

   
   

    
    

   
   
   
   

    
    
			
     
     <groupId>org.springframework.boot
     
     </groupId>
    
    
   
   

   
   

    
    

   
   
   
   

    
    
			
     
     <artifactId>spring-boot-devtools
     
     </artifactId>
    
    
   
   

   
   

    
    

   
   
   
   

    
    
			
     
     <optional>true
     
     </optional>
    
    
   
   

   
   

    
    

   
   
   
   

    
    
		
     
     </dependency>
    
    
   
   
 
 

 
 

   
   

    
    

   
   
   
   

    
    

     
      <build>
    
    
   
   

   
   

    
    

   
   
   
   

    
    
		
     
     <plugins>
    
    
   
   

   
   

    
    

   
   
   
   

    
    
			
     
     <plugin>
    
    
   
   

   
   

    
    

   
   
   
   

    
    
				
     
     <groupId>org.springframework.boot
     
     </groupId>
    
    
   
   

   
   

    
    

   
   
   
   

    
    
				
     
     <artifactId>spring-boot-maven-plugin
     
     </artifactId>
    
    
   
   

   
   

    
    

   
   
   
   

    
    
				
     
     <configuration>
    
    
   
   

   
   

    
    

   
   
   
   

    
    
					
     
     <fork>true
     
     </fork>
    
    
   
   

   
   

    
    

   
   
   
   

    
    
				
     
     </configuration>
    
    
   
   

   
   

    
    

   
   
   
   

    
    
			
     
     </plugin>
    
    
   
   

   
   

    
    

   
   
   
   

    
    
		
     
     </plugins>
    
    
   
   

   
   

    
    

   
   
   
   

    
    
	
     
     </build>
    
    
   
   
 
 

三、IDEA 设置

1. 自动build

2. Register配置

Ctrl+Shift+Alt+/ => Register => 找到并勾选compiler.automake.allow.when.app.running => IDEA重启

四、测试

确认IDEA重启后，debug启动SpringBoot项目，修改第一篇文章的HelloController

 
 

   
   

    
    

   
   
   
   

    
    

     
     @
     
     RequestMapping
     
     (value = 
     
     "sayhello"
     
     , 
     
     method
     
      = 
     
     RequestMethod
     
     .
     
     GET
     
     )
    
    
   
   

   
   

    
    

   
   
   
   

    
    
	
     
     public 
     
     String sayhello(){
    
    
   
   

   
   

    
    

   
   
   
   

    
    
		
     
     return 
     
     "Hello SpringBoot !";
    
    
   
   

   
   

    
    

   
   
   
   

    
    

     
     	}
    
    
   
   
 
 

"Hello SpringBoot !"; == > "Hello SpringBoot 2 !";

测试成功
