忽略保存休眠实体的瞬态模式

如何保存休眠实体并忽略（不正确）瞬态模式。忽略保存休眠实体的瞬态模式

例如：

@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; 
} 
}

，我想保存：

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