上面这个异常,我这边是端口号占用了。 换个端口号就可以。
还有,可以根据栈信息排查下。 从下往上看,可以看到,项目启动时
//这里将bean 销毁 destroy
at org.springframework.context.support.AbstractApplicationContext.destroyBeans(AbstractApplicationContext.java:1032)
然后继续往上看
//这里getBean
at org.springframework.context.support.AbstractApplicationContext.getBean(AbstractApplicationContext.java:1080)
这个错误就发生在从容器中获取单例bean的时候
//获取单例bean
at org.springframework.beans.factory.support.DefaultSingletonBeanRegistry.getSingleton(DefaultSingletonBeanRegistry.java:216)
