@Converter

You can use @Converter annotation to specify a custom converter for modification of the data value(s) during the reading and writing of a mapped attribute.

@Target({TYPE, METHOD, FIELD})
 @Retention(RUNTIME)
 public @interface Converter {
    String name();
    Class converterClass(); 
 }

The following example shows how to use the @Converter annotation to specify Employee field gender.

Example: @Converter Annotation

@Entity
 public class Employee implements Serializable{
     ...
     @Basic
     @Converter (
         name="genderConverter",
         converterClass=org.myorg.converters.GenderConverter.class
     )
     @Convert("genderConverter")
     public String getGender() {
         return gender;
     }
     ...
 }
