经发现异常提职localSessionFilter文件有问题于是找到
package com.hsit.filter;import java.io.IOException;import javax.servlet.Filter;

import javax.servlet.ServletException;

又发现是java.lang.AbstractMethodError 错，该错误一般是混淆的错。
发现 at org.apache.catalina.core.ApplicationFilterConfig.initFilter(ApplicationFilterConfig.java:285)
于是就重写了初始化方法
@Overridepublic void init(FilterConfig filterConfig) throws ServletException {}@Overridepublic void destroy() {}重新打包部署就可以了
