An example of one-way many-to-one association of hibernate in JSP development

Testing one-way many-to-one correlation based on one-to-many

Definition of hibernate many-to-one relationship:

What is different from one-way one-to-many is that one-to-many is the one who cares about the set set, which is defined in the mapping file.

&lt;set name="" table=""&gt;
&lt;key name="" /&gt;
&lt;one to many class="One more package plus class name"/&gt;
&lt;/set&gt;

: One-way many-to-one, much simpler examples of one-party class that define one-party class in the mapping file:

&lt;many-to-ont name="" class="Permanent Class" column="Class name of foreign key"&gt;

Java code:

Grade g=new Grade(2, "java", "Enterprise Project 2"); 
  Student s=new Student(1, "Wang Shuling"); 
  //Affiliate Relationship  (g); 
   
  Session session=(); 
  Transaction t=(); 
  (g); 
  (s); 
  (); 
  ();

That is, complete the one-way many-to-one relationship
