org.hibernate.exception.SQLGrammarException: could not execute query

引起的错误其实很简单。百度谷歌了好久没用，终于自己发现了问题...
先贴出错误：

解决方法： 项目ftp上传时候必须进行必要的修改

   其实很简单，是【没连接到数据库所以查询不到。】把你的ssh框架中的pojo的映射文件打开把 找到如：<class name="com.pojos.TbUsers" table="tb_users" catalog="tpmob">    把catalog="改成你的服务器上的远程数据库名字";   因为它默认的是你本地项目名称。所以上传时候会报错找不到...
