A lightweight Java8 ORM library.

objectos::orm

A lightweight Java8 ORM library.

A simple O/RM

objectos::orm is not meant to be a Hibernate replacement. It is a simpler and lighter weight alternative.

Also, it uses annotation processing to generate code, meaning that, when debugging, all code is visible.

objectos::orm is nothing more than a collection of objectos::pojo plugins leveraging two more projects:

• objectos::schema for Java based database schema definition
• objectos::sql for a Java based SQL query writing

A simple mapping

In its simplest form, you just need to annotate your entity class with a @Pojo annotation and its properties with the corresponding column annotations:

@Pojo
abstract class Employee {

  @EMPLOYEE.EMP_NO
  abstract int emp_no();

  @EMPLOYEE.BIRTH_DATE
  abstract LocalDate birthDate();

  @EMPLOYEE.FIRST_NAME
  abstract String firstName();

  @EMPLOYEE.LAST_NAME
  abstract String lastName();

  @EMPLOYEE.HIRE_DATE
  abstract LocalDate hireDate();

  Employee() {
  }

  // the EmployeeBuilder/Pojo is generated for you 
  public static EmployeeBuilder builder() {
    return new EmployeeBuilderPojo();
  }

}

objectos::orm is at Maven central.
