还是这个错误老师我又整整的找了一天，还是没找到，进度一直卡在这里，还急着看完找工作里，一直卡在这里三四天了，百度这个问题我都能看到第七八页了，还是没解决，我域名访问http://www.lpfyy.fun/o2o/这个路径可以看到Hello World! 要是访问http://www.lpfyy.fun/o2o/frontend/index就报错500了，提示spring-dao错误我看了好久没了也找不出来， @老师你qq微信了什么的我加你你给我弄一下吧，对你来说两三分钟就搞定了，对我来说我都搞了好几天了，还没弄好，

同学好，不好意思我这几天在国外，用mac不支持远程调试，而且也不能开这个口子，否则很多同学都找翔仔远程调试的话就忙不过来了，平时都加班到深夜，望理解一下。这个问题是服务器内部异常，但是光看这些信息只能猜测是jar没有被打进来，同学可以把打包的war解压出来，看看lib里面有没有对应的jar包，也可以将打包出来的war在本地跑一下，看看能不能跑起来，先确保在本地的tomcat目录下，对应的war包在tomcat启动后能够解压出来并访问得到，不行的话需要看看tomcat目录里面的logs/catalina.out最新报了什么异常。

如果是jar包没打进去的问题，可以参考这个
