本文解决了一个关于在同一个Tomcat服务器下部署多个Java应用时出现的异常问题。该问题源于不同应用创建了相同的单例对象，导致启动失败。通过在各应用的web.xml文件中配置不同的webAppRootKey参数来区分它们，从而避免了冲突。

场景：同一个tomcat下部署多个java工程。

问题现象： 启动tomcat时报异常Singleton bean creation not allowed while the singletons of this factory are in destruction

问题原因：不同的工程分别创建了同一个单例。

处理方案：1、在应用的web.xml文件中，配置不同的webAppRootKey，<param-value>值可以自定义，只要相同tomcat下的各个工程保持不同即可。

  1. <context-param>  
  2.   <param-name>webAppRootKey</param-name>  
  3.   <param-value>web.sample.root</param-value>  
  4. </context-param>

进入@Configuration，发现@Configuration核心是@Component，说明Spring的配置类也是Spring的一个组件。可以看到它是由 @AutoConfigurationPackage，@Import(EnableAutoConfigurationImportSelector.class)这两个而组成的，我们先说@AutoConfigurationPackage，他是说：让包中的类以及子包中的类能够被自动扫描到spring容器中。他是通过工厂的方式创建的。

spring启动错误Singleton bean creation not allowed while the singletons of this factory are indestruction 错误来由 今天在公司测试线程服务的时候很蛋疼的遇到这个错，网上解释多重多样，最后还是靠我自己猜出来了 原因 其实很简单，就是你的线程里去拿bean，但是你的主线程在调用这个线程后销毁了，所以bean也会随之销毁，这时候你的线程去获取bean就会报这个错拉 解决方法 因为我是调的springboot的test，
