Question

当系统使用@Size验证单个字段时，它会返回错误消息（确定，它是正确的），但它也会返回带有id的实体，然后如果我尝试再次保存此实体，它会获得我是一个EntityNotFoundException错误。

@Entity
@Table(name = "DOCUMENTS")
public class Document {

   private static final long serialVersionUID = 1L;

   @Id
   @SequenceGenerator(name = "DOC_SEQ", sequenceName = "ID_DOCUMENT_SEQ", allocationSize = 1)
   @GeneratedValue(strategy = GenerationType.SEQUENCE, generator = "DOC_SEQ")
   @Column(name = "ID_DOCUMENT")
   private Integer idDocument;

   @Column(name = "NOME_ARQUIVO")
   @NotNull
   @Size(max = 100, message = "Validation message.")
   private String nomeArquivo;
}

按照以下错误消息：

javax.ejb.EJBException: javax.persistence.EntityNotFoundException: Unable to find com.procergs.pra_aj4.ed.Document with id 13172

Answer 1

此问题已解决。如果我使用@Max或@Min代替@Size它可以很好地工作。

Answer 2

您还可以使用以下方式为字符串字段设置最大列长度：

@Column(nullable = true, length = 1000) // max length will be 1000
private String someString;

@Size验证消息后的EntityNotFoundException
