In Hibernate Annotation, the annotations of entity BLOB and CLOB types are somewhat different from those of ordinary entity attributes. The specific operations are as follows: BLOB type, declared as byte []:

Private byte [] content

Notes:

@ Lob @ Basic (fetch = FetchType.LAZY) @ Column (name = "CONTENT", columnDefinition = "BLOB", nullable=true) public byte [] getContent () {return this.content;} public void setContent (byte [] content) {this.content = content;}

CLOB type, which can be declared as String:

Private String remark

Notes:

Lob @ Basic (fetch = FetchType.EAGER) @ Column (name= "REMARK", columnDefinition= "CLOB", nullable=true) public String getRemark () {return this.remark;} public void setRemark (String recvdocRemark) {this.remark = remark;}

Follow the notes above to set up the entity class and you are done.
