Hibernate in session.load () method error

Session session = sessionFactory.openSession();		
  Transaction transation = session.beginTransaction();		
  //获取需要修改的用户
  Employee emp = (Employee)session.load(Employee.class, 2);

If I only write directly int type , will complain , but if you change the type Integer instance can the code below

Session session = sessionFactory.openSession();		
  Transaction transation = session.beginTransaction();		
  //获取需要修改的用户
  Employee emp = (Employee)session.load(Employee.class, new Integer(2));

Why is there such a situation ? You can not do auto-unboxing boxing ? I use the jdk is 1.7

program is not directly in the eclipse shows a syntax error , it means automatic entry box is ok .
but specific to hibernate in the operation , that depends on your version of itself referenced hibernate support auto dismantling it.
should be your hibernate itself does not allow to do this, so you just have to write the type of object to be queried , and this has nothing to do with jdk

use int tried it, easy to use.

If a syntax error is really the case, make sure that the eclipse window-> Preferences-> java-> Compiler, inside the Compiler compliance level is not selected, the corresponding version of your JDK compiler. JDK7 I have not used , but I want you to choose one which is at least 1.5 , in order to ensure automatic disassembly is correct.

not , JDK1.5 after auto dismantling, my other projects can directly use an int type

I am also the same problem, seemingly only with Integer Package that could be used
