前端展示状态属性，从数据库中数字代号转换为中文解释

直接上代码

public interface CodeEnum {
    Integer getCode();
}
public enum AlarmDataStatus implements CodeEnum {

    warn(1, "提醒"),
    commonly(2, "一般"),
    warning(3, "警告"),
    serious(4, "严重");
    private Integer code;
    private String message;

    AlarmDataStatus(Integer code, String message) {
        this.code = code;
        this.message = message;
    }

    @Override
    public Integer getCode() {
        return code;
    }

    public void setCode(Integer code) {
        this.code = code;
    }

    public String getMessage() {
        return message;
    }

    public void setMessage(String message) {
        this.message = message;
    }

}

public class EnumUtil {
    //根据code和枚举对象的Class返回对应的枚举
    public static  T getByCode(Integer code, Class enumClass) {
        //遍历该枚举对象类型中的所有枚举
        for(T each : enumClass.getEnumConstants()){
            if(each.getCode().equals(code)){
                return each;
            }
        }
        return null;
    }

}

代码中使用 一行搞定
  tAlarmRules.setAlarmRankDesc(EnumUtil.getByCode(alarmRank,AlarmDataStatus.class).getMessage());
