select 属性名1,属性名2 from 类名"); 别名查询:session.createQuery("select 别名 from 类名 别名"); 3、QBC检索方式： 查询全部数据：session.createCriteria...(类名.class).list(); 根据条件查询：session.createCriteria(类名.class).add(Restrictions.条件方法名("属性名",条件)); 分页查询：Criteria...criteria = session.createCriteria(类名.class);----criteria.setFirstResult(起始索引);-----criteria.setMaxResults...(每页显示的记录数); 排序查询：session.createCriteria(类名.class).addOrder(Order.asc/desc("属性名")); 统计查询：session.createCriteria
简单查询 //createCriteria(类名.class) Criteria criteria = session.createCriteria(Course.class); List<Course...c); } 分页查询 //criteria.setFirstResult(行号); //criteria.setMaxResults(条数); Criteria criteria = session.createCriteria...System.out.println(c); } 排序查询 //criteria.addOrder(Order.desc("属性名")) Criteria criteria = session.createCriteria...<= le ne like like in in or or and and //Restrictions.eq("属性名",值) Criteria criteria = session.createCriteria...System.out.println(c); } 统计查询 //setProjection(Projections.rowCount()) Criteria criteria = session.createCriteria
简单来说，Criteria Query可以看作是传统SQL的对象化表示，如： Criteria criteria=session.createCriteria(TUser.class); criteria.add...Criteria criteria=session.CreateCriteria(TUser.class); TUser exampleUser=new TUser(); exapleUser.getName...复合查询 Criteria criteria=session.createCriteria(TUser.class); Criteria addrCriteria=criteria.createCriteria...addrSet){ System.out.println(addr.getAddress()); } } 红色部分就是我们新增的复合查询条件，可以看到，我们可以通过Criteria.createCriteria...C riteria criteria=session.createCriteria(TUser.class); criteria.setProjection(Projections.groupProperty
Criteria时，相关代码如下： final RolePermissionExample example = new RolePermissionExample(); example.createCriteria...().andRoleIdEqualTo(roleId); example.createCriteria().andProjectIdEqualTo(projectId);...经调整，代码修改如下： final RolePermissionExample example = new RolePermissionExample(); example.createCriteria

开发中遇到Mybatis生成的Example通过调用createCriteria()来创建Criteria并设置查询条件的情况。 但是需要换一个查询条件再次查询时发现再次调用该方法“无效果"。...发现问题原因如下，我们看下生成的Exmaple的源码： public Criteria createCriteria() { Criteria criteria = createCriteriaInternal...createCriteriaInternal() { Criteria criteria = new Criteria(); return criteria; } 发现调用createCriteria
