连接数据库代码有问题
或者是你通过tomcat打开网页过多

是不是maven没有配置,或者配置错误。可以百度一下怎么配置maven

配置问题或者代码问题,可以百度,这方面的问题博客上有解决方案 的具体看下

应该是jdk 版本问题,你检查下版本

配置web.xml过程中

[java] view plain copy


LogFilter1

com.zyx.handler.LogInterceptor





LogFilter

/*

的filter的filter-name和filter-mapping中的filter-name不一样导致出现相同的错误,经过我的测试的确报错如上

在配置web.xml过程中



LogFilter1

com.zyx.handler.LogInterceptor





LogFilter

/*

重装一下tomcat

解决方法:
tomcat中的servlet-api.jar包,servlet版本和开发时用的版本不一致。

原因:
tomcat为其配套的servlet-api.jar不匹配或项目工程lib下有低版本的servlet-api.jar,
tomcat7以前的这个包没有getSessionCookieConfig这个方法,7的包有这个方法,
解决方法,删除项目工程lib文件夹的低版本的servlet-api.jar,tomcat的lib文件夹里用默认带的jar包
或者把tomcat换成6的
