忽略保存hibernate实体的瞬态模式

问题描述

例如：

<$ p

@Inheritance（strategy = InheritanceType.SINGLE_TABLE）
@DiscriminatorColumn（name =` @Entity
@Table（name =`REQUEST`接收器，discriminatorType = DiscriminatorType.STRING，长度= 20）
public abstract class Request实现UUIDAble {
@Id @GeneratedValue（strategy = GenerationType.AUTO）
private Integer id;
@Transient
@NotNull
@Pattern（regexp =^（[0-9a-fA-F]）{8} - （[0-9a-fA-F]）{ 4} - （[0-9A-FA-F]）{4} - （[0-9A-FA-F]）{4} - （[0-9A-FA-F]）{12} $）
private String vaucher;

@Enumerated（EnumType.STRING）
@Column（name =name，nullable = false）
private RequestName name;

public RequestName getName（）{
return name;
}
public void setName（RequestName name）{
this.name = name;
}

public String getVaucher（）{
return vaucher;
}
public void setVaucher（String vaucher）{
this.vaucher = vaucher;
}
}


我想保存它：

 请求请求= new Request（）; 
 request.setVaucher（123）; 
 request.setName（RequestName.SYSTEM）; 
  

Spring产生错误：

  javax.validation.ConstraintViolationException：对于组[java.value.groups.Default，]

解决方案

请参阅。默认情况下，Hibernate（ORM）检查默认验证组的每个约束。所以你可以把这个特定的约束放入另一个组中。

参见以获取验证组的解释。

How to save hibernate entity and ignore (not correct)transient pattern.

for example:

@Entity
@Table(name="`REQUEST`")
@Inheritance(strategy=InheritanceType.SINGLE_TABLE)
@DiscriminatorColumn(name="`receiver`",discriminatorType=DiscriminatorType.STRING,length=20)
public abstract class Request implements UUIDAble{
    @Id @GeneratedValue(strategy=GenerationType.AUTO)
    private Integer id;
    @Transient
    @NotNull
    @Pattern(regexp="^([0-9a-fA-F]){8}-([0-9a-fA-F]){4}-([0-9a-fA-F]){4}-([0-9a-fA-F]){4}-([0-9a-fA-F]){12}$")
    private String vaucher;

@Enumerated(EnumType.STRING)
@Column(name="name",nullable=false)
private RequestName name;

public RequestName getName() {
    return name;
}
public void setName(RequestName name) {
    this.name = name;
}

public String getVaucher() {
    return vaucher;
}
public void setVaucher(String vaucher) {
    this.vaucher = vaucher;
}
}

and i want to save it:

Request request = new Request();
request.setVaucher("123");
request.setName(RequestName.SYSTEM);

Spring generate error:

解决方案

See http://docs.jboss.org/hibernate/validator/4.2/reference/en-US/html_single/#validator-checkconstraints-orm. By default, Hibernate (the ORM) checks every constraint of the default validation group. So you might put this particular constraint into another group.

See http://docs.jboss.org/hibernate/validator/4.2/reference/en-US/html_single/#validator-usingvalidator-validationgroups for explanations on validation groups.
