JPA使用枚举

使用converter

@Converter
public class PeriodStatusConverter implements AttributeConverter {
@Override
public Integer convertToDatabaseColumn(PeriodStatus status) {
return status.getId();
}

@Override
public PeriodStatus convertToEntityAttribute(Integer id) {
    if(id == null){
        return null;
    }
    for(PeriodStatus type:PeriodStatus.values()){
        if(type.getId() == id.intValue()){
            return type;
        }
    }
    return null;
}

}

domain

@Convert(converter = PeriodStatusConverter.class)
private PeriodStatus status;
