@Target(value={METHOD,FIELD}) @Retention(value=RUNTIME) public @interface Lob
Portable applications should use the Lob
annotation
when mapping to a database Lob type. The Lob
annotation may be used in conjunction with the Basic
annotation or the ElementCollection
annotation when the
element collection value is of basic type. A Lob
may
be either a binary or character type.
The Lob
type is inferred from the type of the
persistent field or property, and except for string and
character-based types defaults to Blob.
Example 1: @Lob @Basic(fetch=LAZY) @Column(name="REPORT") protected String report; Example 2: @Lob @Basic(fetch=LAZY) @Column(name="EMP_PIC", columnDefinition="BLOB NOT NULL") protected byte[] pic;
