使用特殊主键的Hibernate检索对象

Question

This is how I can retrieve an Object with the primary key 1.

user = null;

session = sessionFactory.openSession();

session.beginTransaction();

user = (UserDetails) session.get(UserDetails.class, 1);

System.out.println(user);

But I want to know, how I can retrieve an Object, that has a primary key like: "Primary:1_Key_1-ID"?

Answer 1

If your primary key is type of String then this works for you.

String key= "1_Key_1-ID";
UserDetails user = (UserDetails) session.get(UserDetails.class, key);
