严重: Exception sending context initialized event to listener instance of class org.springframework.web.context.ContextLoaderListener
org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'sessionFactory' defined in class path resource [beans.xml]: Invocation of init method failed; nested exception is java.lang.NoSuchMethodError: org.apache.log4j.Logger.isTraceEnabled()Z

Answer 1

NoSuchMethodError

 

看看log4j.jar是否引入，一般有以下原因：

 

1. jar包冲突

2. jar包版本不对

追问

他全都是myeclipse自带的啊。。
