Jpa中自定义枚举映射方式

@Entity
public class User{
  @Id
  private Integer userId;

  private String name;

  private Integer age;

  @Enumerated(STRING)
  private Status status;
}

public enum Status{
   ACTIVE,DELETED,BANED
}

public enum Status{
  ACTIVE(1),DELETED(0),BANED(-1);

  private final int value;

  public int getValue(){
    return this.value;
  }

  public static Status of(int value){
    for(Status status:Status.values()){
      if(status.getValue() == value){
        return status;
      }
    }
    throw new IllegalArgumentException("Invalid value: "+value);
  }

}

//@Converter(autoApply=true) 设置了这个注解，在下面的Entity 的例子中就可以省略 @Convert
public class StatusConverter implements AttributeConverter<Status,Integer>{

  @Override
  public Integer convertToDatabaseColumn(Status attribute){
    return attribute.getValue();
  }

  @Override
  public Status convertToEntityAttribute(Integer dbData){
    return Status.of(dbData);
  }
}

@Entity
public class User{
  @Id
  private Integer userId;

  private String name;

  private Integer age;

  @Convert(converter = StatusConverter.class, attributeName = "status")
  private Status status;

}
