tomcat使用一段时间后报错

tomcat使用一段时间后报错,使用大约一天后某个查询报错,重启tomcat后该查询又可继续使用,但一段时间后还是报同样的错,报错信息如下:
信息: Illegal access: this web application instance has been stopped already. Could not load sun.reflect.GeneratedMethodAccessor79. The eventual following stack trace is caused by an error thrown for debugging purposes as well as to attempt to terminate the thread which caused the illegal access, and has no functional impact.

8080端口应该已经被占用了,参考这个解决吧http://jingyan.baidu.com/article/67662997372ecc54d51b8423.html

是因为在tomcat重启的时候,因为之前的tomcat中的线程还没有完全关闭,新启动tomcat就会报这个异常,不过这个不影响正常使用,只是跳个异常挺烦人的

kkkkkkkkkkkkkk123 感谢回答,你说的这个情况是重启的时候发生的,但是我程序是报这个错、功能无法实现,需要重启tomcat才能正常使用

把tomcat webapps文件夹里文件清空应该就可以了
