internship：数据库表和建立的实体类及对应的枚举类之间的联系示例

数据库表：

发现tunnel_id和duan字段存在相同的情况，这是为了处理一种情况 同一类有多个分类 且分类又有分支。比如隧道是一类别事物 那么隧道有多个有命名存在的实体 每个实体又有各自的属性类别。这样便可以开始业务的内容。

依据表建类：
注意注解的使用 该类是能复用的。

@Data
@Accessors(chain = true)
@EqualsAndHashCode(callSuper = false)
@TableName("表名")
@ApiModel(value="对象", description="信息")
public class BizTunnelConfig extends Model<BizTunnelConfig> {
    

    private static final long serialVersionUID = 1L;

    @ApiModelProperty(value = "主键id")
    @TableId(value = "id", type = IdType.AUTO)
    private Integer id;

    @ApiModelProperty(value = "所属隧道id")
    @TableField("tunnel_id")
    private Integer tunnelId;
    
    @ApiModelProperty(value = "区域名称")
    @TableField("name")
    private String name;

    @ApiModelProperty(value = "enter/exit/pdx/pdd/xjx/xjd")
    @TableField("duan")
    private String duan;

    @ApiModelProperty(value = "left/right")
    @TableField("direction")
    private String direction;

    /** * 隧道固有属性 */
    @ApiModelProperty(value = "桩号前缀")
    @TableField("mark_prefix")
    private String markPrefix;
   
    @ApiModelProperty(value = "隧道长度")
    @TableField("tunnel_length")
    private Double tunnelLength;

    @ApiModelProperty(value = "当前掌子面总进尺")
    @TableField("zzm_jinchi")
    private Double zzmJinchi;

    @ApiModelProperty(value = "最新掌子面桩号")
    @TableField("zzm_mark")
    private Double zzmMark;

    @ApiModelProperty(value = "")
    @TableField(exist = false)
    private String zzmMarkStr;

    @ApiModelProperty(value = "掌子面进尺/洞长的比例,百分数0-100")
    @TableField("zzm_percent")
    private Double zzmPercent;
    
    @ApiModelProperty(value = "当前进尺")
    @TableField("erc_jinchi")
    private Double ercJinchi;

    @ApiModelProperty(value = "")
    @TableField("erc_mark")
    private Double ercMark;

    @ApiModelProperty(value = "")
    @TableField(exist = false)
    private String ercMarkStr;

    @ApiModelProperty(value = "二衬进尺/洞长的比例,百分数0-100")
    @TableField("erc_percent")
    private Double ercPercent;

}

对应实体属性类别 类：

package com.hyd.daring.model.index;

import io.swagger.annotations.ApiModelProperty;
import lombok.Data;
import lombok.experimental.Accessors;

/** * 首页施工进度model * * @author */
@Data
@Accessors(chain = true)
public class ScheduleModelDemo {
    

    @ApiModelProperty(value = "隧道id")
    private Integer tunnelId;

    @ApiModelProperty(value = "隧道名称")
    private String tunnelName;

    @ApiModelProperty(value = "隧道总长")
    private Double length;

    @ApiModelProperty(value = "类别1...")
    private Double ZzmJinchi ;

    @ApiModelProperty(value = "类别1....")
    private Double ErcJinchi ;

    @ApiModelProperty(value = "类别1...完成率")
    private Double ZzmRatio ;

    @ApiModelProperty(value = "类别1...完成率")
    private Double ErcRatio ;

    @ApiModelProperty(value = "类别2...进尺")
    private Double OtherZzmJinchi ;

    @ApiModelProperty(value = "类别2...进尺")
    private Double OtherErcJinchi ;

    @ApiModelProperty(value = "类别2...完成率")
    private Double OtherZzmRatio ;

    @ApiModelProperty(value = "类别2...完成率")
    private Double OtherErcRatio ;
}

枚举类：
这里的枚举类是依据 数据库表格 字段duan的 pdx pdd xjx…建立的，意味着枚举类的建立是多个的。以下是举例：

package com.hyd.daring.enums;

/** * 平导大小里程枚举 * @author yyp */
public enum DXlichengDemo {
    
    PDX("PDX","平导小里程"),
    PDD("PDD", "平导大里程");

    private final String key;
    private final String value;

    public String getKey() {
    
        return key;
    }

    public String getValue() {
    
        return value;
    }

    DXlichengDemo(String key, String value) {
    
        this.key = key;
        this.value = value;
    }

    public static String getValueByKey(String key) {
    
        DXlichengDemo[] enums = DXlichengDemo.values();
        for (int i = 0; i < enums.length; i++) {
    
            if (enums[i].getKey().equals(key)) {
    
                return enums[i].getValue();
            }
        }
        return "";
    }
}

实现类：

 public Object scheduleInfo(Integer tunnelId) {
    
        BizTunnel tunnel = tunnelMapper.selectById(tunnelId);
        List<BizTunnelConfig> tunnelConfigs = this.list(new QueryWrapper<BizTunnelConfig>().eq("tunnel_id", tunnelId));
        ScheduleModelDemo scheduleModel = new ScheduleModelDemo()
                .setTunnelId(tunnel.getId())
                .setTunnelName(tunnel.getName());
        if(tunnel.getName().equals("隧道平导"))
        {
    
            //按照项目id分组
            for (BizTunnelConfig tunnelConfig : tunnelConfigs) {
    
                //隧道总长
                scheduleModel.setLength(tunnelConfig.getTunnelLength()/1000);
                if (tunnelConfig.getDuan().equals(DXlichengDemo.PDX.getKey())) {
    
                    //平导小里程
                    scheduleModel
                            .setZzmJinchi(tunnelConfig.getZzmJinchi())
                            .setZzmRatio(tunnelConfig.getZzmPercent())
                            .setErcJinchi(tunnelConfig.getErcJinchi())
                            .setErcRatio(tunnelConfig.getErcPercent());
                } else {
    
                    //平导大里程
                    scheduleModel
                            .setOtherZzmJinchi(tunnelConfig.getZzmJinchi())
                            .setOtherZzmRatio(tunnelConfig.getZzmPercent())
                            .setOtherErcJinchi(tunnelConfig.getErcJinchi())
                            .setOtherErcRatio(tunnelConfig.getErcPercent());
                }
            }
            return scheduleModel;
        }
        else if(tunnel.getName().equals("隧道斜井"))
        {
    
            for (BizTunnelConfig tunnelConfig : tunnelConfigs) {
    
                //隧道总长
                scheduleModel.setLength(tunnelConfig.getTunnelLength()/1000);
                if (tunnelConfig.getDuan().equals(XJDXlichengDemo.XJX.getKey())) {
    
                    //斜井小里程
                    scheduleModel

                }
            }
            return scheduleModel;

        else {

            for (BizTunnelConfig tunnelConfig : tunnelConfigs) {
    
                //隧道总长
                scheduleModel.setLength(tunnelConfig.getTunnelLength() / 1000);
                if (tunnelConfig.getDuan().equals(Duan.ENTER.getKey())) {
    
                    //进口端
                    scheduleModel
                            .setZzmJinchi(tunnelConfig.getZzmJinchi())
