pom.xml文件添加配置信息
1.添加依赖包
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-devtools</artifactId>
<optional>true</optional>
<scope>true</scope>
</dependency>
2.添加spring-boot-maven-plugin
<build>
<plugins>
<plugin>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-maven-plugin</artifactId>
<configuration>
<!--fork : 如果没有该项配置,肯呢个devtools不会起作用,即应用不会restart -->
<fork>true</fork>
</configuration>
</plugin>
</plugins>
</build>
即可完成springboot热部署
注意不要将build automaticautomatically关闭 否则热部署会失败
