EclipseLink JPA


The @Convert annotation specifies that a named converter should be used with the corresponding mapped attribute.

 @Target({METHOD, FIELD})
 public @interface Convert {
    String value() default "none";

The @Convert has the following reserved names:

  • serialized – places the org.eclipse.persistence.mappings.converters.SerializedObjectConverter on the associated mapping.
  • none – does not place a converter on the associated mapping.
@Convert Annotation Attributes
Attribute Description Default Required?
value The String name for your converter. "none" String No

The following example shows how to use the @Convert annotation to define the Employee field gender.

Example: @Convert Annotation
 public class Employee implements Serializable{
     public String getGender() {
         return gender;
