  在您要加载表的某些列的情况下，您可能需要 Projection

  Criteria crit = getSession().createCriteria(TestTable.class, "t");
  ProjectionList projectionList = Projections.projectionList();
  projectionList.add(Projections.property("id"));
  projectionList.add(Projections.property("param1"));
  projectionList.add(Projections.property("param2"));
  projectionList.add(Projections.property("param1"));
  crit.setProjection(projectionList);
  List results = crit.list();

  如果你要做的就是查询TestTable的行并获取TestTable的hibernate对象，只需在你想要检索的Hibernate对象的类上创建一个Criteria对象 .

  Criteria crit = sess.createCriteria(TestTable.class);
  List results = crit.list();
