hibernate错误收集

1. java.lang.IllegalStateException: No data type for node: org.hibernate.hql.ast.tree.IdentNode


\-[IDENT] IdentNode: 'userId' {originalText=userId}

比如select userId from Metters where metterstate is null，你这里面使用了大写的Metters，如果你改成小写就没了

//-----------------------------------------------一些查询所用到的

这个是 Work与User关联（id）

from Work w where w.user.id=? and w.sortone=? and w.sorttwo=?

hibernate获取外键的方法， 外键在Metters上 userId，通过查询Metters里面的不为空的内容，来获取以知对应的外键

这个是 Metters与User关联（id）

String sql="select m.user.id from Metters as m where m.metterstate is null";

控制台打印如下：Hibernate: select metters0_.userId as col_0_0_ from metters metters0_ where metters0_.metterstate is null
