麻烦各位帮我看下这个错误怎么解决，重装电脑之前还可以正常运行的，昨天一键还原了电脑，再次重试后，发现就报错了，之前程序运行的时候还可以查询数据库的，现在查询没有结果。在百度、谷歌上搜寻无果，只好来发帖寻求帮助了，百度谷歌上搜到的解决方案是将servlet.xml里面的reloadable里面的true换成false，我之前就一直是true,可以正常运行。

重启一下电脑,或运行一下应该服务器的关闭程序,如果你用的是tomcat的话,可以这样..打开tomcat的目录里的bin文件夹,运行里面的shutdown.bat就可以了
this web application instance has been stopped already
重启服务器
this web application instance has been stopped already
这个的意思基本上就是说你的web应用实例已经停止了，自然没办法加载你web应用的相关的类文件，
因为你还原了系统，可能把tomcat的某些服务搞出问题了，我建议你重新安装下tomcat应该就可以解决，
