How can I transform Entity-Based diagram to a JPA java code

I have class diagram created with "Sparx Enterprise Architect v8.0" and i need to generate JPA-based classes with annotations that reflect relations to use it in the code. The problem is that i can convert it to EJB but not JPA which is required for my task.

G9 plugin from Marketplace in Spring Tool Suit did job.

  1. Install Plugin G9
  2. Select Project (JAVA)
  3. Import "Import Database Model"
  4. Select JDBC Driver (In my case mysql)
  5. Maintain JDBC Connection
    • New
    • Provide Driver Name, Add Jar, Port, Driver Class and connection url along with schema (jdbc:mysql://localhost:3306/{schema_name})
  6. Close JDBC Connection Box
  7. Port, DB Name, User Name and PWD
  8. Fetch

If you export your model to ecore format, then you can use Texo to generate JPA annotated POJO for your model.

I don't know this product, however they claim that it:

supports modeling of database schema and automatic generation of DDL scripts for eleven DBMS targets out-of-the-box

Once you have the database schema I believe there are various tools that can reverse engineer it and generate JPA entities. Few random hits in Google:
