枚举类中通过code值获取对应的desc值

@Getter
@NoArgsConstructor
public enum TaskRecordTypeEnum {

    STOPTASK(0,"禁用任务"),

    STARTTASK(1,"启用任务");

    private int code;

    private String desc;

    TaskRecordTypeEnum(int code, String desc) {
        this.code = code;
        this.desc = desc;
    }

    public static TaskRecordTypeEnum getInstance(int code) {
        TaskRecordTypeEnum[] values = TaskRecordTypeEnum.values();
        for (TaskRecordTypeEnum value : values) {
            if (value.getCode() == code) {
                return value;
            }
        }
        throw new IllegalArgumentException("Unable to parse the provided code " + code);
    }

}

通过TaskRecordTypeEnum.getInstance(code);可将从数据库里查出的code值转换成value值，更方便前端处理。
