HIBERNATE 级联查询问题，求教O(∩_∩)O

Java code

//classroom MAPPINGpublic class Classroom {private String id ;private String name;private Student student;//SETTER AND GETTER;

Java code

//student MAPPINGpublic class Student {private String uid ;private String uname;private String upsw;//SETTER AND GETTER;

Java code

//执行方法public List<Classroom > getClassroom (String cid) {String hql = " from Classroom where id="+cid;List<Classroom > classroomlist = getHibernateTemplate().find(hql);return classroomlist ；

现状：getClassroom (String cid)会产生2条语句，一条是查询Class表的。另一条是查询Student 表的。

问：这就是级联查询？如何控制（取消）？请各位帮帮忙，呵呵

[解决办法]
你的classroom里是不是配置了student关联，将配置设置为lazy=true
