SpringBoot应用程序一直在重新启动(重新启动循环) - spring.devtools

2022-09-04 01:29:43

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

我的IDE是Spring工具套件,我切换为“自动构建”,因为我认为这可以在后台更改文件,从而触发重新启动

我的问题是,在tomcat和应用程序ist启动后,它会立即在无限循环中重新启动所有内容:

Workaroud:我知道我可以停止这种行为,但如果真的有必要,我当然希望重新启动。spring.devtools.restart.enabled = false

问题:

  • 如何找出哪个文件更改触发重新启动?
  • 有人有类似的问题吗?

答案 1

好的,我发现与我们的应用程序在应用程序启动后几秒钟后通过Spring Boot DevTools重新启动应用程序相关的问题。

DevTools 扫描了日志文件文件夹,由于应用程序在启动后将日志写入此文件夹,因此每次启动都会通过 DevTools 触发整个应用程序的重新加载。

解决方案是从应用程序的监视中排除日志文件夹。yml:

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

如果您使用的是普通属性文件,则它完全相同,但中间有 (.) 个点。另请参阅 http://www.logicbig.com/tutorials/spring-framework/spring-boot/restart-exclude/ 以供参考。


答案 2

我已经添加了appplication.properties,然后它工作正常。断续器

spring.devtools.restart.additional-exclude=logs/**
