Hibernate Annotation中BLOB、CLOB注解写法
在hibernate Annotation中,实体BLOB、CLOB类型的注解与普通的实体属性有些不同,具体操作如下:
BLOB类型,类型声明为byte[]:
private byte[] content;
注解:
?@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类型,类型声明为String即可:
private String remark;
注解:
?? @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;
??? }
按照以上的设置实体类的注解就搞定了。
