解决方案三：
求救啊今天还要打个版本那现在出这个问题我去。手贱啊
解决方案四：
问题还得看替换的是什么，可能是拦截器的配置类报错了
解决方案五：
引用3楼cyf282501的回复:
问题还得看替换的是什么，可能是拦截器的配置类报错了
替换的是两个logic类里面就是增加了一个查询条件页面都没改动过就报错了
解决方案六：
你部署的时候不是直接替换.class文件后重启吗？你是如何部署？
解决方案七：
首先给你一点建议，动态替换部署前，先备份原来的class，万一出错可以及时还原。接着帮你解决这个问题：出现这个错误两个可能，servlet没有对空指针异常进行捕获，另外检查下你的ｊｓｐ，有没有为ｎｕｌｌ的请求。
解决方案八：
eclipse下重新部署下程序。可能是没有编译类文件！也可以吧代码退回原来的在试着看看，如果可以运行了那么就说明你的代码编写有问题查查空指针可能出现的地方！
