idea中springboot的热启动配置方法

1.在pom.xml引入相关依赖



    org.springframework

    springloaded

    1.2.6.RELEASE





    org.springframework.boot

    spring-boot-devtools

    1.3.0.RELEASE

    true

2.“File” -> “Settings” -> “Build,Execution,Deplyment” -> “Compiler”，选中打勾 “Build project automatically” 。

3.组合键：“Shift+Ctrl+Alt+/” ，选择 “Registry” ，选中打勾 “compiler.automake.allow.when.app.running”

在2021版之前的idea一般均可通过上述方法，如若没有可以在setting里面勾选

小细节勾选compiler.document.save.enabled(指定是否启用保存项目响应当文档被更改)，并将它们的对应的保存动作延时时间适当缩小，或者使用默认值也可以、

常见问题

1.启动时出现下图时，该问题是因为组件的版本号而导致的问题
