org.hibernate.hql.ast.tree.PathNode异常解决

java.lang.ClassCastException: org.hibernate.hql.ast.tree.SqlNode cannot be cast to org.hibernate.hql.ast.tree.PathNode

 public Member() {
    }
    public Member(String memberId,String memberName){
        this.memberId = memberId;
        this.memberName = memberName;
    }

     getHibernateTemplate().find("select new Member(mb.memberId,mb.memberName)from Member mb");

Hql语法中提到：
select new Family(mother, mate, offspr) from DomesticCat as mother join mother.mate as mate left join mother.kittens as offspr假设类Family有一个合适的构造函数.
所以你的应该是
select new Member(mb,mb.memberId,mb.memberName)from Member mb或者
select new Member(mb,memberId,memberName)from Member as mb join mb.memberId as memberId left join mb.memberName as memberName

select new Member(mb,mb.memberId,mb.memberName)from Member mb
