Exception occurred during processing request: could not extract ResultSet; SQL [n/a]; nested exception is org.hibernate.exception.SQLGrammarException: could not extract ResultSet

今天在编码的时候遇到了 Exception occurred during processing request: could not extract ResultSet; SQL [n/a]; nested exception is org.hibernate.exception.SQLGrammarException: could not extract ResultSet这个问题，也是找了老半天不懂什么原因，后来找了好多论坛，总结了一下，只要出现了sql的问题，基本都是bean或者XXX.hbm.xml写错了 大家可以检查一下名称和类型是不是和sql中配置不一样。
