摘要：本文通过一个实例讲述如何通过Spring2+Hibernate3来快捷操作数据库中的Lob字段。
环境：oracle10g、Srping2、Hibernate3、JUint4
说明：由于时间紧迫，没有详细写出思路。运行一下例子就明白了。
一、创建实体并添加Xdoclet的Hibernate标签
/**
* @author leizhimin
* @hibernate.mapping default-lazy="false"
* @hibernate.meta attribute="class-description" value="工作日志"
* @hibernate.class table="rc_gzrz"
*/
public class WorkNote {
private Long id; //标识
private Date workDate; //日期
private String weather; //天气
private String content; //日志内容(Clob)
private String state; //日志状态
private Long orgId; //机构id
private Long userId; //用户id
private Date createDate; //创建日期
private byte[] image; //图片
public static final String WORKNOTE_BLANK = "00"; //未填写
public static final String WORKNOTE_FULL = "11"; //已填写
/**
* @hibernate.id generator-class="sequence" column="BS"
* @hibernate.meta attribute="field-description" value="标识"
* @hibernate.generator-param name="sequence" value="SEQ_GW"
*/
public Long getId() {
return id;
}
public void setId(Long id) {
this.id = id;
}
/**
* @hibernate.property column="workDate" not-null="false" type="timestamp"
* @hibernate.meta attribute="field-description" value="工作日期"
*/
public Date getWorkDate() {
return workDate;
}
public void setWorkDate(Date workDate) {
this.workDate = workDate;
}
/**
* @hibernate.property column="weather" not-null="false" length="24"
* @hibernate.meta attribute="field-description" value="天气"
*/
public String getWeather() {
return weather;
}
public void setWeather(String weather) {
this.weather = weather;
}
/**
* @hibernate.property column="content" not-null="false" type="text"
* @hibernate.meta attribute="field-description" value="内容"
*/
public String getContent() {
return content;
}
public void setContent(String content) {
this.content = content;
}
/**
* @hibernate.property column="state" not-null="false" length="2"
* @hibernate.meta attribute="field-description" value="状态"
*/
public String getState() {
return state;
}
public void setState(String state) {
this.state = state;
}
/**
* @hibernate.property column="orgId" type="long"
* @hibernate.meta attribute="field-description" value="机构id"
*/
public Long getOrgId() {
return orgId;
}
public void setOrgId(Long orgId) {
this.orgId = orgId;
}
/**
* @hibernate.property column="userId" type="long"
* @hibernate.meta attribute="field-description" value="用户id"
*/
public Long getUserId() {
return userId;
}
public void setUserId(Long userId) {
this.userId = userId;
}
/**
* @hibernate.property column="createDate" not-null="false" type="timestamp"
* @hibernate.meta attribute="field-description" value="创建日期"
*/
public Date getCreateDate() {
return createDate;
}
public void setCreateDate(Date createDate) {
this.createDate = createDate;
}
/**
* @hibernate.property column="image" type="blob" not-null="false"
* @hibernate.meta attribute="field-description" value="图片"
*/
public byte[] getImage() {
return image;
}
public void setImage(byte[] image) {
this.image = image;
}
