借款信息列表

需求

一、后端实现

1、扩展实体对象

列表的结果需要关联查询，数据字典的数据也需要展示对应的文本内容而不是值，除了定义VO的方式，我们也可以使用扩展实体类的方式 

在BorrowInfo类中扩展以下字段

//扩展字段
@ApiModelProperty(value = "姓名")
@TableField(exist = false)
private String name;

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

@ApiModelProperty(value = "其他参数")
@TableField(exist = false)
private Map param = new HashMap<>();

2、Controller

添加 AdminBorrowInfoController

@Api(tags = "借款管理")
@RestController
@RequestMapping("/admin/core/borrowInfo")
@Slf4j
public class AdminBorrowInfoController {
 
    @Resource
    private BorrowInfoService borrowInfoService;
 
    @ApiOperation("借款信息列表")
    @GetMapping("/list")
    public R list() {
        List  borrowInfoList = borrowInfoService.selectList();
        return R.ok().data("list", borrowInfoList);
    }
}

3、Service

接口：BorrowInfoService

List selectList();

实现：BorrowInfoServiceImpl 

@Resource
private DictService dictService;
 
@Override
public List selectList() {
    List borrowInfoList = baseMapper.selectBorrowInfoList();
    borrowInfoList.forEach(borrowInfo -> {
        String returnMethod = dictService.getNameByParentDictCodeAndValue("returnMethod", borrowInfo.getReturnMethod());
        String moneyUse = dictService.getNameByParentDictCodeAndValue("moneyUse", borrowInfo.getMoneyUse());
        String status = BorrowInfoStatusEnum.getMsgByStatus(borrowInfo.getStatus());
        borrowInfo.getParam().put("returnMethod", returnMethod);
        borrowInfo.getParam().put("moneyUse", moneyUse);
        borrowInfo.getParam().put("status", status);
    });
 
    return borrowInfoList;
}

4、Mapper

接口：BorrowInfoMapper

<select id="selectBorrowInfoList" resultType="com.atguigu.srb.core.pojo.entity.BorrowInfo">
    SELECT
    bi.*,
    b.name,
    b.mobile
    FROM
    borrow_info AS bi
    LEFT JOIN borrower AS b ON bi.user_id = b.user_id
    WHERE bi.is_deleted = 0
</select>

 BorrowInfoStatusEnum.getMsgByStatus

   @Override
    public String getNameByparantDictAndValue(String dictCode,Integer value) {
        QueryWrapper wrapper = new QueryWrapper<>();
        wrapper.eq("dict_code",dictCode);
        Dict dict = baseMapper.selectOne(wrapper);
        if(dict==null){
            return "";
        }
        wrapper=new QueryWrapper<>();
        wrapper.eq("parent_id",dict.getId())
                .eq("value",value);
        Dict dict1 = baseMapper.selectOne(wrapper);
        if (dict1==null){
            return  "";
        }
        return  dict1.getName();
    }
