我在使用 Openjpa (Websphere 应用程序服务器 7) 与数据库互动。 是否有可能在 java 实体文件中指定一个 blob 大小? 它看起来像 :
@Id
@GeneratedValue(strategy = GenerationType.AUTO)
private Long id;
@Lob
@Nullable
private byte[] content;
默认情况下 DB2 的大小为 1MB 。 我想将它更改为 20MB 。

您可以使用
@Id
@GeneratedValue(strategy = GenerationType.AUTO)
private Long id;
@Lob
@Nullable
@Column(length = 20971520)
private byte[] content;
