Question

hibernate session.get报错

package test;
import hibernate.HibernateSessionFactory;
import model.Booktable;
import org.hibernate.Session;
import org.hibernate.SessionFactory;
import org.hibernate.Transaction;
import org.hibernate.cfg.Configuration;

public class Test {

public static void main(String[] args){
Session s=HibernateSessionFactory.getSession();
Booktable bt=new Booktable();
bt=(Booktable)s.get(bt.getBookid(),1);
System.out.println(bt.getBookcb());
HibernateSessionFactory.closeSession();
}

}
}
The method get(Class, Serializable) in the type Session is not applicable for the
arguments (Integer, int)
请问怎么解决

Answer 1

The method get(Class, Serializable)错误里面已经提示你了，get(Class, Serializable)里面2个参数前一个是个java类，你写的是bt.getBookid()，这个返回一个Integer,肯定不对

Answer 2

修改一下：

public static void main(String[] args){
		Session s=HibernateSessionFactory.getSession();
		
		Booktable  bt=(Booktable)s.get(Booktable.class,1);
		System.out.println(bt.getBookcb());
		HibernateSessionFactory.closeSession();
	}
