我在将字节数组保存到 Informix 数据库时遇到问题，我将向您展示我是如何尝试的：
在 Fichero.java 中，我有以下内容：
@Column(name="fichero", columnDefinition="blob")
private byte[] contenido;
我必须这样做，因为我无法让 Informix+Hibernate 接受 @Lob 注释（是的，我尝试扩展 Hibernate 的方言解决方法，但它对我不起作用）
然后我读取一个文件并将其转换为字节数组：
文件管理器.java
private byte[] fromFile2ByteArray(String nombreFichero) throws FileNotFoundException, IOException{
File file = new File(nombreFichero);
InputStream is = new FileInputStream(file);
byte[] contenido = new byte[(int)file.length()];
is.read(contenido);
is.close();
return contenido;
}
接下来我尝试使用以下方法将其保存到我的数据库中：
FicheroDAO.java
public void save(Object object) {
getHibernateTemplate().save(object);
}
其中该对象是我的 Fichero 对象。
Buuuuut，我得到以下异常。
Hibernate:
/* insert es.cosas.modelo.datos.dominio.fichero.Fichero
*/ insert
into
cosas_fichero
(fichero, idEnvio, nombrefichero, respuesta)
values
(?, ?, ?, ?)

异常中的下一行指向 FicheroDAO.java 文件以及它尝试保存对象的行号...
有任何想法吗？
