hibernate中Criteria能多表查询吗?

Question

Criteria criteria = session.createCriteria(User.class);criteria.createCriteria("department","d").list();

Answer 1

把你的需求说清楚一些，hbm及相关代码列出来

Answer 2

List result = session.createCriteria(obj1.getClass())
 .add(Example.create(obj1))
 .createCriteria(obj2.getClass())
 .add(Example.create(obj2))
 .list()
你可以试下

Answer 3

Cretiria里有createCretiria(Class clazz)这样的方法么？

Answer 4

不好意思搞错了饿List result = session.createCriteria(Cat.class)
 .add(Example.create(cat))
 .createCriteria("mate")
 .add(Example.create(cat.getMate()))
 .list()
一般对关联对象

Answer 5

DetachedCriteria dc = DetachedCriteria.forClass(TExpert.class);
     dc.addOrder(Order.desc("expertid"));
     dc.createAlias("extype","b");   
     dc.add(Property.forName("b.extypeid").eq(new Long(expertForm.getExtypeId())));
 dc.add(Property.forName("name").like(expertForm.getSearchName(),MatchMode.ANYWHERE));
 dc.add(Property.forName("keyword").like(expertForm.getSearchName(),MatchMode.ANYWHERE));
 }
