enum 유형에 대한 맵을 만드는 방법은 무엇입니까?

Question

하나는 최대 절전 모드 지정이며 JPA 2.0 사양으로 지정되지 않았기 때문에 @Type 주석을 사용하고 싶지 않습니다.

type_id 유형의 데이터베이스는 integer이며 내 데이터베이스에는 두 개의 다른 정수 값 : 1, 2 만있을 수 있습니다. 나는 열거 형을 만들었습니다

public enum ExternalTransactionType { 

    TO_LOTO(1), WITHDRAW(2); 

    private int value; 

    ExternalTransactionType(int value) { 
     this.value = value; 
    } 

    public String getName() { 
     return name(); 
    } 

    public int getValue() { 
     return value; 
    } 

    public static ExternalTransactionType getByValue(int value) { 
     for (ExternalTransactionType type : ExternalTransactionType.values()) { 
      if (value == type.getValue()) { 
       return type; 
      } 
     } 
     throw new IllegalArgumentException("Illegal value: " + value); 
    } 
} 

다음과 같이 매핑에 속성을 추가하려고 :

@Column(name="type_id") 
private Integer typeId; 

public ExternalTransactionType getType() { 
    return ExternalTransactionType.getByValue(typeId); 
} 

public void setType(ExternalTransactionType type) { 
    this.typeId = type.getValue(); 
} 

을하지만

criteria.add(Restrictions.eq("typeId", ExternalTransactionType.TO_LOTO)) 

같은 제한을 추가 할 때 ClassCastException가 Throw됩니다. 뭐가 문제 야?

type_id 유형 Integer하지 Enum 일예로하기 때문에

Answer 1

패스 정수 값보다는 열거 형

criteria.add(Restrictions.eq("typeId", ExternalTransactionType.TO_LOTO.getValue()))
