Class UlidConverter

  • All Implemented Interfaces:
    javax.persistence.AttributeConverter<String,​String>

    public class UlidConverter
    extends Object
    implements javax.persistence.AttributeConverter<String,​String>
    Serves to pass through the string ULID representation of the field in the Java entity class into a varchar field in the database. This is the most readable option and serves as the easiest option during data troubleshooting. However, the Base32 string representation does use more memory to store the value in the database, which can be important when considering database index size. There is a byte array converting version of this class as well. Which version is used is determined by which library is mounted on the classpath at runtime.

    String fields in an entity class that should receive this persistence behaviour should be annotated with @Convert(converter = UlidConverter.class).
