Bidirectional Many-To-Many Relationship with Join Tables in Hibernate

In bidirectional association, we will have navigation in both direction, i.e, both side of the association will have the reference to the other side. The both side of the association will implement one of the collection interfaces, if it has the reference to the other entity.

In many to many relationship, one multiple objects can have relationship with multiple target objects. Let’s consider CD and Artist. So multiple CDs can be written by multiple Artists or multiple Artists can write multiple CDs. So we will create three tables CD, CDArtist and Artist in the database and we will see how many-to-many relationship works step by step.

Step 1. Create tables

Create table – cd


Create table – artist


Create table – cdartist


Step 2. Create a java project in any Java based IDE and configure for hibernate jars.

Step 3. Create hibernate reverse engineering and configuration file.

Step 4. Create hibernate utility class which creates singleton SessionFactory from which Session object will be created.


Step 5. Create mapping xml file and POJO for artist table. Look at the xml file.




Step 6. Create mapping xml file and POJO for cd table.


Step 7. Now we will create a main class for testing many-to-many using join tables.


Step 8. Run the main class and see the output as shown below. While we save value for artist, the below values are stored into the database tables.

inserted data into artist table

inserted data into cd table

inserted data into cdartist table

Console Output


That’s all. Thanks for your reading.
