Answer 2

lxNews is not mapped [from lxNews]; nested exception is org.hibernate.hql.ast.QuerySyntaxException: lxNews is not mapped [from lxNews]

Answer 3

 nested exception is org.hibernate.hql.ast.QuerySyntaxException: lxNews is not mapped [from lxNews]
lxNews 这是你要查询的类名？ 如果是类的话，要与类名相同，应该首字母大写“LxNews”楼主试试，如果还不行的话把查询方法贴出来看看
