这是我试图坚持的对象
@Entity
@Table(name="Timbre")
public class Timbre implements Serializable{
/**

private static final long serialVersionUID = -8846422129143878578L;
@Id
@Column(name="idTimbre")
@GeneratedValue private int idTimbre;
@Column(name="scott")
private String scott;
@Column(name="formato")

@Column(name="rutaImg")

和Controller类：
@RequestMapping(value="addTimbre", method=RequestMethod.POST)
public String agregarTimbre(@ModelAttribute("t")
Timbre t, BindingResult result){
try {
t.setPais(timbreDAO.searchPais(t.getNombrePais()));
SubirImagen upload = new SubirImagen();
String nombre=t.getPais().getNombre().substring(0,3)+t.getScott()+".jpg";
t.setRutaImg(upload.grabarFicheroALocal(nombre, t.getFile().getFileItem()));
timbreDAO.addTimbre(t);
} catch (Exception e) {
// TODO: handle exception
e.printStackTrace();
}
return "timbre";
}
问题是当尝试在数据库中保存对象时抛出此异常：
org.hibernate.type.SerializationException：无法反序列化
每个对象都有serialVersionUID生成的eclipse，但我不知道是什么原因造成这个错误。
答案 0 :(得分：1)
您可以尝试将'file'属性设置为瞬态，如下所示。 （音色课）
私有瞬态CommonsMultipartFile文件;
