Question

hibernate 哪个方法是查找一条数据

Answer 1

//获取单个对象
public Object getObjectById(Class cls, int Id) {
Session session = sf.openSession();
try {
Object obj = session.get(cls, Id);
if (obj != null) {
return obj;
}
} catch (Exception e) {
System.out.println("获取" + cls + "失败!" + e.getMessage());
} finally {
session.close();
}
return null;
}
cls 是类名 id不解释

Answer 2

findById();
