休眠 - 如何通过注释设置SQL类型的？ [英] Hibernate - How to set sql-type by annotation?

问题描述

我有一个文件为一个byte [] fileContent。由Hibernate和默认Hibernate生成我的MySQL-方案SQL型fileContent的设置为BLOB。

但是，BLOB不是我的文件不够大。我将至少需要MEDIUMBLOM甚至LONGBLOB。

但我怎么可以标注我的领域，这样Hibernate会产生与我作为一个LONGBLOB领域的计划？
我有谷歌搜索当前第2小时，没有得到任何东西...

应该不是这是一个如此简单和常见的任务，它应该被记录的地方??

请帮助失意的程序员！

  @WhatAnnotationCanIUseToForceHibernateToMakeThisALONGBLOB ????
私人字节[] fileContent;
 

解决方案

你试过

  @Column（columnDefinition =LONGBLOB）
私人字节[] fileContent;
 

I have a file as a byte[] fileContent. My mySql-scheme is generated by Hibernate and by default hibernate sets the sql-type of fileContent to BLOB.

But a BLOB is not big enough for my files. I will need at least a MEDIUMBLOM or even a LONGBLOB.

But how can i annotate my field so that Hibernate will generate the scheme with my field as a LONGBLOB? I have search google for 2 hours now without getting anything...

Shouldn't this be a so simple and common task that it should be documented somewhere??

Please help a frustrated programmer!!

@WhatAnnotationCanIUseToForceHibernateToMakeThisALONGBLOB????
private byte[] fileContent;

解决方案

Have you tried

@Column(columnDefinition = "LONGBLOB")
private byte[] fileContent;
