ssh整合的时候出现了下面的错误，不知道是不是少导入了什么jar包呀？

严重: Exception sending context initialized event to listener instance of class org.springframework.web.context.ContextLoaderListener

Answer 1

不是空指针异常，是报没有这方法错误，你查一下你的配置文件有没配错了，<listener>整合SSH时不用先搞监听器，要一步一步来，比如先整合struts，开服务器看是否整合成功，然后再整合hibernate，再测试，再整合spring，因为这样的整合过程，你可以很快发现问题，很有效的查找问题所在……祝你好运！

Answer 2

java.lang.NoSuchMethodError:

Answer 3
