spring使用Test测试时报错：Singleton bean creation not allowed while singletons of this factory are in destru

一、问题描述

利用Test测试任务时时，启动服务抛出异常：Singleton bean creation not allowed while the singletons of this factory are in destruction (Do not request a bean from a BeanFactory in a destroy method implementation!)

具体的错误信息如下：

Exception in thread "pool-3-thread-1" Exception in thread "pool-3-thread-2" org.springframework.beans.factory.BeanCreationNotAllowedException: Error creating bean with name 'XXXXXX': Singleton bean creation not allowed while the singletons of this factory are in destruction (Do not request a bean from a BeanFactory in a destroy method implementation!)at org.springframework.beans.factory.support.DefaultSingletonBeanRegistry.getSingleton(DefaultSingletonBeanRegistry.java:216)at org.springframework.beans.factory.support.AbstractBeanFactory.doGetBean(AbstractBeanFactory.java:302)at org.springframework.beans.factory.support.AbstractBeanFactory.getBean(AbstractBeanFactory.java:202)at org.springframework.beans.factory.support.DefaultListableBeanFactory.getBeansOfType(DefaultListableBeanFactory.java:534)at org.springframework.beans.factory.support.DefaultListableBeanFactory.getBeansOfType(DefaultListableBeanFactory.java:523)at net.paoding.rose.jade.context.spring.SpringDataSourceFactoryDelegate.getDataSource(SpringDataSourceFactoryDelegate.java:38)at net.paoding.rose.jade.dataaccess.DefaultDataAccessFactory.getDataAccess(DefaultDataAccessFactory.java:46)at net.paoding.rose.jade.statement.SelectQuerier.execute(SelectQuerier.java:60)at net.paoding.rose.jade.statement.SelectQuerier.execute(SelectQuerier.java:56)at net.paoding.rose.jade.statement.JdbcStatement.execute(JdbcStatement.java:112)at net.paoding.rose.jade.context.JadeInvocationHandler.invoke(JadeInvocationHandler.java:143)at com.sun.proxy.$Proxy53.getSapPayDetailList(Unknown Source)at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1149)at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:624)at java.lang.Thread.run(Thread.java:748)

二、原因分析

经过原因分析，是单例的bean在创建的时候，容器已经处于销毁阶段，生命周期不同，不允许再次创建生产Bean。为什么会发生这个问题呢？

具体看了代码，是因为我的任务提交给了线程池，

    @Testpublic void sendNoReadMsg() {ftpCarService.read();}

    @Async@Overridepublic void read() {ExecutorService cachedThreadPool = Executors.newFixedThreadPool(20);long startTime = System.currentTimeMillis();log.info("<<<<<<<执行ftp:xxx.xxx.xxx.xxx的读写!>>>>>>>>" + Thread.currentThread().getName());FtpUtils ftp = new FtpUtils(ip,userName,userPwd,port,path);List<String> str = null;...................

test主线程运行时，启动了线程池，线程池中的任务会加载bean，但因为异步原因，任务提交给线程池后，主线程结束了，开始销毁bean容器，而线程池任务有需要创建出bean，所以出现上述的异常情况。

三、解决方案

1、测试用例中增加线程池的任务判断，如果有线程池任务未完成，当前主线程阻塞。

2、测试时去掉异步。
