我在将数据存储到PostgreSQL上的OID列时遇到了非常奇怪的问题。应用配置为：
这与字段有关：
@Lob
@Basic(fetch = FetchType.LAZY)
@Column(name = "content", nullable = false, updatable = false)
public byte[] getByteContent() {
return content;
}
public void setByteContent(final byte[] content) {
this.content = content;
}
针对OID的persistence.xml中的配置：
<property name="hibernate.jdbc.use_streams_for_binary" value="true"/>
<property name="hibernate.connection.autocommit" value="false"/>
<property name="hibernate.dialect" value="org.hibernate.dialect.PostgreSQLDialect"/>
以这种方式注释的字段对postgres方言说它是OID类型。因为我们还必须支持MS SQL Server DB，所以它使它更加复杂，因为我们不能使用任何注释组合。我无法在＆＃34;生产＆＃34; env with postgres，但是当我从IDE运行它时它会起作用 - 这很奇怪。要更具体的数据无法保存，但是当数据已经存储在postgres中时（例如从IDE填充DB运行并重新连接生产），可以从OID列中读取。在制作时我收到此错误：

我已经阅读了很多关于Hibernate vs PostgreSQL OID的提示，但到目前为止还没有任何工作。任何帮助将不胜感激。
