MyBatis Generator - collection properties (List<Object) in complex objects

I am using MyBatis Generator to generate POJO objects which resemble my database structure. I would also like to have a list property in every object which has one to many relationships. Is this achievable ("C# alike class generation")? Thanks in advance

Solution

  • Unfortunately, no.

    One to one/many relationships that generator need to acknowledge by using other tables are not supported by MyBatis Generator.

    As stated in the document:

    MBG seeks to make a major impact on the large percentage of database operations that are simple CRUD (Create, Retrieve, Update, Delete). You will still need to hand code SQL and objects for join queries, or stored procedures.

    Regarding the POJOs, MBG generates the following fields/classes:

    a class to match the primary key of the table (if there is a primary key)

    a class to match the non-primary key fields of the table (except BLOB fields)

    a class to include the BLOB fields of a table (if the table has BLOB fields)

    a class to enable dynamic selects, updates, and deletes
