Class DatabaseAwareLobType

  • All Implemented Interfaces:
    Serializable, org.hibernate.type.BasicType, org.hibernate.type.ProcedureParameterExtractionAware<String>, org.hibernate.type.ProcedureParameterNamedBinder, org.hibernate.type.SingleColumnType<String>, org.hibernate.type.StringRepresentableType<String>, org.hibernate.type.Type
    public class DatabaseAwareLobType
extends org.hibernate.type.AbstractSingleColumnStandardBasicType<String>
    A Hibernate @Type used to properly support the CLOB in both Postgres and Oracle. PostgreSQL doesn't have a CLOB type, instead it's a TEXT field. Normally, you'd use org.hibernate.type.TextType to support TEXT, but that won't work for Oracle. https://github.com/hibernate/hibernate-orm/blob/5.6/hibernate-core/src/main/java/org/hibernate/type/TextType.java This Type checks if we are using PostgreSQL. If so, it configures Hibernate to map CLOB to LongVarChar (same as org.hibernate.type.TextType) If not, it uses default CLOB (which works for other databases).
