一、IDEA配置
当我们修改了Java类后,IDEA默认是不自动编译的,而spring-boot-devtools又是监测classpath下的文件发生变化才会重启应用,所以需要设置IDEA的自动编译:
(1)File->Settings->Compiler->Build Project automatically
(2)File->Settings->Advanced settings->Allow auto-make to start even if developed application iss currently running
二、Spring Boot XML配置
Spring Boot XML配置文件引入依赖devTools
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-devtools</artifactId>
<scope>runtime</scope>
<optional>true</optional>
</dependency>
XML 配置,build增加fork
<build>
<plugins>
<plugin>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-maven-plugin</artifactId>
<configuration>
<fork>true</fork>
</configuration>
</plugin>
</plugins>
</build>
三、Resources下面的YML配置
spring:
devtools:
restart:
enabled: true
