Oracle 休眠 ORA-01461 CLOB

//大家好。 我的问题是我无法在 clob 字段中写入大日期。 currentli 我可以写长度不超过4000的字符串。你能解释一下为什么我不能将 clob 写入 clob 字段吗？ 我在用着：

• Oracle 数据库 11g 企业版版本 11.2.0.1.0
• 列表项 hibernate 4.2.6.Final
• 列表项 ojdbc 11.1.0.7.0

我的实体是：

@Entity
@Table(....)
public class UiViewSettings implements java.io.Serializable {

    private Integer id;
    private String viewName;
    private String userName;
    private Clob data;
        ....
    @Column(name = "VIEW_DATA", nullable = false)
    public Clob getData() {
        return this.data;
    }
        ....
}

我的更新实体的代码：

UiViewSettings viewSettings = new UiViewSettings();
Clob createClob;
//creatind clob
viewSettings.setData(createClob);
session.update(viewSettings);

我尝试了几种创建 Clob 的方法：

createClob = new SerialClob(xml.toCharArray());

and

connection = DriverManager.getConnection(...);
createClob = ((OracleConnection)connection).createClob();
createClob.setString(1, xml);

两种方式都会抛出异常：

这段代码在 SQL Developer 中执行良好

DECLARE
 REALLYBIGTEXTSTRING CLOB := '123';
 i int;
BEGIN

    WHILE LENGTH(REALLYBIGTEXTSTRING) <= 90000 LOOP
        REALLYBIGTEXTSTRING := REALLYBIGTEXTSTRING || '000000000000000000000000000000000';
    END LOOP;
    DBms_output.put_line('I have started inputting your clob: '|| length(REALLYBIGTEXTSTRING)); 
   INSERT INTO UI_VIEW_SETTINGS(view_id , view_name ,user_name, view_data) VALUES(0, 'test', 'test', REALLYBIGTEXTSTRING);
    DBms_output.put_line('I have finished inputting your clob: '|| length(REALLYBIGTEXTSTRING)); 
end ;

尝试添加@LOB(type = LobType.CLOB)注释在你的顶部data访问器方法：

@Column(name = "VIEW_DATA", nullable = false)
@LOB(type = LobType.CLOB)
public Clob getData() {
    return this.data;
}
