jpa转换枚举、转换以及入库数据、状态值发生变化可以不影响前端

import com.peony.common.enums.PlanStatus;
import org.apache.poi.ss.formula.functions.T;

import javax.persistence.AttributeConverter;
import javax.persistence.Converter;

@Converter(autoApply = true)
public class PlanStatusConverter implements AttributeConverter<PlanStatus,String> {


    @Override
    public String convertToDatabaseColumn(PlanStatus attribute) {
        return attribute.getCode();
    }

    @Override
    public PlanStatus convertToEntityAttribute(String dbData) {
        return PlanStatus.valueOf(dbData);
    }
}

枚举

S_TO_POSTPONE("14", "延期待审核"),
    /**
     *     S_CHANGE_THE_DATE("11", "改期"),
     */
    S_TO_CHANGE_THE_DATE("10", "改期待审核"),
    ;

    private final String code;

    private final String description;

    public  PlanStatus valueOfCode(String code) {
        for (PlanStatus value : values()) {
            if (value.code.equals(code)) {
                return value;
            }
        }
        return null;
    }

po类

 这样就可以查询和写入自动转换了  、

注意：

@Converter(autoApply = true)这个注解只有在同一个包下才生效

处理单个可以在字段上添加

@Convert(converter = SyslogStartConverter.class)
