Generated POJOs

Applies to ✅ Open Source Edition   ✅ Express Edition   ✅ Professional Edition   ✅ Enterprise Edition

Every table and view in your database will generate a POJO implementation that looks like this:

// JPA annotations can be generated, optionally
@jakarta.persistence.Entity
@jakarta.persistence.Table(name = "BOOK", schema = "TEST")
public class Book implements java.io.Serializable

// An interface common to records and pojos can be generated, optionally
, IBook {

    // JSR-303 annotations can be generated, optionally
    @NotNull
    private Integer id;

    @NotNull
    private Integer authorId;

    @NotNull
    @Size(max = 400)
    private String title;

    // Every column generates a getter and a setter
    @Id
    @Column(name = "ID", unique = true, nullable = false, precision = 7)
    @Override
    public Integer getId() {
        return this.id;
    }

    @Override
    public void setId(Integer id) {
        this.id = id;
    }

    // [...]
}

Flags influencing generated POJOs

These flags from the code generation configuration influence generated POJOs:

  • daos: POJOs are a pre-requisite for DAOs. If DAOs are generated, POJOs are generated as well
  • dateAsTimestamp: This influences all relevant getters and setters
  • immutablePojos: Immutable POJOs have final members and no setters. All members must be passed to the constructor
  • interfaces: If interfaces are generated, POJOs will implement them
  • jpaAnnotations: JPA annotations are used on generated records (details here)
  • jpaVersion: Version of JPA specification is to be used to generate version-specific annotations. If it is omitted, the latest version is used by default. (details here)
  • pojosAsJavaRecordClasses: If you're using the JavaGenerator, this will generate POJOs as (immutable) Java 16 record types
  • pojosAsScalaCaseClasses: If you're using the ScalaGenerator, this will generate POJOs as (mutable or immutable) Scala case classes
  • pojosAsKotlinDataClasses: If you're using the KotlinGenerator, this will generate POJOs as (mutable or immutable) kotlin data classes
  • pojosToString: Whether POJOs should have a generated toString() implementation.
  • pojosEqualsAndHashCode: Whether POJOs should have generated equals() and hashCode() implementations.
  • unsignedTypes: This influences all relevant getters and setters
  • validationAnnotations: JSR-303 validation annotations are used on generated records (details here)

Flags controlling POJO generation

POJO generation can be activated using the pojos flag
