Solution:
Lob Annotation
A Lob annotation specifies that a persistent property or field should be persisted as a large object to a database-supported large object type. 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. 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.
Since you’re using JPA, use the Lob
annotation (and optionally the Column
annotation). Here is what the JPA specification says about it:
9.1.19 Lob Annotation
A Lob
annotation specifies that a persistent property or field should be persisted as a large object to a database-supported large object type. 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. 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.
So declare something like this (set the length to the max) :
@Lob
@Column(name="CONTENT", length=512)
private String content;
