今天做Tomcat迁移Spring Boot,遇到一个坑。启动没有错误,CPU特别高

经过把堆栈kill -3 打印出来,发现堆栈特别长(没有死循环),所有的堆栈信息都集中在org.springframework.beans.factory.support.DefaultSingletonBeanRegistry#onSuppressedException类。一下是部分截取。

现象:每个类初始化的时候,都会去FactoryBean里跟进类型获取Singleton,而FactoryBean又需要把他管理的XML的所有Bean都初始化,结构初始化的时候都会出错(因为有类不存在或者类名错误),结构所有的类初始化的时候都会走一遍这个出错的过程。最后导致启动。

最后解决办法:debug至org.springframework.beans.factory.support.DefaultSingletonBeanRegistry#onSuppressedException,找到出错的类,解决它然后启动就好OK了。

org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'iDaiRecallDOMapper': Unsatisfied dependency expressed through method 'setSqlSessionTemplate' parameter 0; nested exception is org.springframework.beans.factory.CannotLoadBeanClassException: Cannot find class [com.pajk.promotion.mq.sender.SendMessageManager1] for bean with name 'sendMessageManager' defined in class path resource [META-INF/spring/application-manager.xml]; nested exception is java.lang.ClassNotFoundException: com.pajk.promotion.mq.sender.SendMessageManager1
