非常感谢你的帮助〜
我有一个CLOB数据类型的DB字段。最初我们在POJO中使用了String，它设法使用以下JdbcTypeField将数据存储到DB中
new JdbcTypeField(Types.CLOB, "VALUE_X", String.class, "valueX")
但是，插入更大的数据时会遇到问题。 ORA-01461: can bind a LONG value only for insert into a LONG column-Occurs when querying
现在我们尝试使用以下设置将变量更改为Clob：
new JdbcTypeField(Types.CLOB, "VALUE_X", Clob.class, "valueX"),
但是，我们遇到了以下错误，对此错误有任何想法吗？
