SpringBoot应用程序一直在重启(重启循环) - spring.devtools

Question

我有一个带有嵌入式tomcat的spring boot应用程序,并且如果在类路径中发生了某些变化,则使用spring-boot-devtools重新启动应用程序.

我的IDE是Spring Tool Suite,我切换了"自动构建",因为我认为这可能会在后台更改触发重启的文件

我的问题是,在tomcat和应用程序启动后,它立即在无限循环中重启所有内容:

Workaroud:我知道spring.devtools.restart.enabled = false我可以阻止这种行为,但我当然希望重新启动,如果真的有必要的话

题:

• 如何找出哪个文件更改会触发重启？
• 有人有过类似的问题吗？

Answer 1

好的,在应用程序启动后的几秒钟后,我发现问题与我们的应用程序通过Spring Boot DevTools重新启动有关.

DevTools扫描了日志文件文件夹,因为应用程序在启动后将日志写入此文件夹,每次启动都会触发通过DevTools重新加载整个应用程序.

解决方案是从application.yml中的监视中排除日志文件夹:

spring:
  devtools:
    restart:
      exclude: logs/**

如果您使用普通属性文件,它只是相同但中间有(.)点.另请参阅http://www.logicbig.com/tutorials/spring-framework/spring-boot/restart-exclude/以供参考.
