多輸入框查詢

需求分析

任意一個輸入框，輸入內(nèi)容點擊搜索都可以精準(zhǔn)搜索到對應(yīng)的內(nèi)容

代碼實現(xiàn)

Controller接口編寫

 @PostMapping("merchant/manage")
 public Result<PageResult<DisputeMerchantManageResponse>>
 merchantDisputeManage(@RequestBody DisputeMerchantManageRequest request) {
     return Result.succ(merchantDisputeFacade.merchantDisputeManage(request));
 }

Result<PageResult<DisputeMerchantManageResponse>>:返回給前端的字段：VO
@RequestBody DisputeMerchantManageRequest request:接收前端傳遞的JSON數(shù)據(jù)：BO
merchantDisputeFacade.merchantDisputeManage(request):調(diào)用Service的merchantDisputeManage方法，傳遞接受的參數(shù)request

Service編寫

MerchantDisputeFacade.java

public PageResult<DisputeMerchantManageResponse> merchantDisputeManage(DisputeMerchantManageRequest request) {
       DisputeMerchantManageBO manageBO = DisputeMerchantManageBO.convert(request);
       List<DisputeMerchantManageResponse> list = merchantDisputeService.merchantDisputeManage(manageBO);
       PageResult<DisputeMerchantManageResponse> pageResult = PageResult.		        				           <DisputeMerchantManageResponse>builder().pageNo(Integer.parseInt(request.getPageNo()))
                .pageSize(Integer.parseInt(request.getPageSize()))
                .total(merchantDisputeService.merchantDisputeManageCount(manageBO)).items(list).build();
        return pageResult;
    }

DisputeMerchantManageBO manageBO = DisputeMerchantManageBO.convert(request):將DisputeMerchantManageRequest對象 request 轉(zhuǎn)換為 DisputeMerchantManageBO對象 manageBO
List<DisputeMerchantManageResponse> list = merchantDisputeService.merchantDisputeManage(manageBO):調(diào)用merchantDisputeService中的merchantDisputeManage方法，傳遞manageBO作為參數(shù)，然后獲取一個List類型的結(jié)果列表

 PageResult<DisputeMerchantManageResponse> pageResult = PageResult.		        				           <DisputeMerchantManageResponse>builder()
     			.pageNo(Integer.parseInt(request.getPageNo()))
                .pageSize(Integer.parseInt(request.getPageSize()))
                .total(merchantDisputeService.merchantDisputeManageCount(manageBO))
     .items(list).build();

PageResult<DisputeMerchantManageResponse>:泛型類封裝分頁查詢結(jié)果，包含頁面信息、頁碼、每頁條目數(shù)、總記錄數(shù)以及當(dāng)前頁面的數(shù)據(jù)項列表
PageResult.<DisputeMerchantManageResponse>builder():創(chuàng)建了用于構(gòu)建PageResult<DisputeMerchantManageResponse>對象的構(gòu)造器；后續(xù)代碼可以通過該構(gòu)造器設(shè)置分頁信息、總記錄數(shù)和當(dāng)前頁面的數(shù)據(jù)項列表，最終得到一個完整的PageResult對象
.pageNo(Integer.parseInt(request.getPageNo())):設(shè)置PageResult對象的當(dāng)前頁碼
.pageSize(Integer.parseInt(request.getPageSize())):設(shè)置PageResult對象的每頁條目數(shù)
.total(merchantDisputeService.merchantDisputeManageCount(manageBO)):設(shè)置PageResult對象的總記錄數(shù)
.items(list).build():設(shè)置PageResult對象的數(shù)據(jù)項列表，并完成構(gòu)建PageResult對象
.items(list):獲取的數(shù)據(jù)項列表list設(shè)置為PageResult對象的數(shù)據(jù)項列表屬性
.build():完成PageResult對象的構(gòu)建，最終得到一個完整的PageResult對象

Service編寫

MerchantDisputeService.java

    public List<DisputeMerchantManageResponse> merchantDisputeManage(DisputeMerchantManageBO disputeMerchantManageBO) {
        Merchant merchant = AuthContextHolder.getLoginMerchant();
        disputeMerchantManageBO.setMerchantNo(merchant.getMerchantNo());
        return merchantDisputeMapper.merchantDisputeManage(disputeMerchantManageBO);
    }

Merchant merchant = AuthContextHolder.getLoginMerchant():通過AuthContextHolder獲取當(dāng)前登錄的商家（Merchant）對象；AuthContextHolder：用于在當(dāng)前線程的上下文中存儲和管理認(rèn)證信息
disputeMerchantManageBO.setMerchantNo(merchant.getMerchantNo()):獲取merchant中的MerchantNo(商戶號)，并存儲在disputeMerchantManageBO中
merchantDisputeMapper.merchantDisputeManage(disputeMerchantManageBO):調(diào)用Mapper層merchantDisputeManage方法將disputeMerchantManageBO作為參數(shù)傳遞給Mapper

Mapper

    List<DisputeMerchantManageResponse> merchantDisputeManage(DisputeMerchantManageBO disputeMerchantManageBO);

Mapper.xml

通過聯(lián)表查詢，查詢merchant_dispute和transaction_order表對應(yīng)字段，通過對disputeMerchantManageBO字段傳入的條件動態(tài)生成查詢語句，并按照創(chuàng)建時間進(jìn)行降序排序，最后返回指定分頁范圍內(nèi)的結(jié)果

    <select id="merchantDisputeManage" resultType="com.moozumi.bean.response.dispute.DisputeMerchantManageResponse">
        select md.id disputeId,md.status disputeStatus,md.type disputeType,o.merchant_no merchantNo,o.unique_id
        uniqueId,md.content disputeContent,
        o.transaction_id transactionId,md.is_reply isReply,md.created_at disputeCreatedAt,o.is_chargeback isChargeback,
        o.billing_email billingEmail,o.create_at paymentCreatedAt,
        o.application_domain,md.order_id
        from merchant_dispute md,transaction_order o
        where md.order_id = o.unique_id
        <if test="merchantNo != null and merchantNo != ''">
            and o.merchant_no = #{merchantNo}
        </if>
        <if test="uniqueId != null and uniqueId != ''">
            and o.unique_id = #{uniqueId}
        </if>
        <if test="disputeStatus != null">
            and md.status = #{disputeStatus}
        </if>
        <if test="disputeType != null">
            and md.type = #{disputeType}
        </if>
        <if test="isReply != null">
            and md.is_reply = #{isReply}
        </if>
        <if test="isChargeback != null">
            and o.is_chargeback = #{isChargeback}
        </if>
        <if test="applicationDomain != null and applicationDomain != ''">
            and o.application_domain = #{applicationDomain}
        </if>
        <if test="orderId != null and orderId != ''">
            and md.order_id = #{orderId}
        </if>
        order by md.created_at desc
        limit #{limit} offset #{offset}
    </select>

BO：對前端傳遞參數(shù)進(jìn)行接收處理

使用DisputeMerchantManageBO處理request的主要目的是為了在業(yè)務(wù)邏輯層（Service層）中更好地封裝業(yè)務(wù)邏輯和數(shù)據(jù)處理

@Data
public class DisputeMerchantManageBO {
    private String merchantNo;
    private String uniqueId;
    private Integer disputeStatus;
    private Integer disputeType;
    private Boolean isReply;
    private Boolean isChargeback;
    private Integer offset;
    private Integer limit;
    private String orderId;
    private String applicationDomain;
    public void setOffset(String pageNo, String pageSize) {
        this.offset = (Integer.parseInt(pageNo) - 1) * Integer.parseInt(pageSize);
    }
    public void setLimit(String pageSize) {
        this.limit = Integer.parseInt(pageSize);
    }
    //DisputeMerchantManageRequest 轉(zhuǎn)換成 BO
    public static DisputeMerchantManageBO convert(DisputeMerchantManageRequest disputeMerchantManageRequest) {
        DisputeMerchantManageBO disputeMerchantManageBO = new DisputeMerchantManageBO();
        disputeMerchantManageBO.setMerchantNo(AuthContextHolder.getLoginMerchant().getMerchantNo());
        disputeMerchantManageBO.setUniqueId(disputeMerchantManageRequest.getUniqueId());
        disputeMerchantManageBO.setDisputeStatus(disputeMerchantManageRequest.getDisputeStatus());
        disputeMerchantManageBO.setDisputeType(disputeMerchantManageRequest.getDisputeType());
        disputeMerchantManageBO.setIsReply(disputeMerchantManageRequest.getIsReply());
        disputeMerchantManageBO.setIsChargeback(disputeMerchantManageRequest.getIsChargeback());
        disputeMerchantManageBO.setOffset(disputeMerchantManageRequest.getPageNo(), disputeMerchantManageRequest.getPageSize());
        disputeMerchantManageBO.setLimit(disputeMerchantManageRequest.getPageSize());
        disputeMerchantManageBO.setOrderId(disputeMerchantManageRequest.getOrderId());
        disputeMerchantManageBO.setApplicationDomain(disputeMerchantManageRequest.getApplicationDomain());
        return disputeMerchantManageBO;
    }
}

request：請求類，前端向后端請求的字段

DisputeMerchantManageRequest.java

DisputeMerchantManageRequest：字段對應(yīng)搜索框需要搜索的字段

@Data
public class DisputeMerchantManageRequest extends PageQuery {
    private String merchantNo;
    private String uniqueId;
    private Integer disputeStatus;
    private Integer disputeType;
    private Boolean isReply;
    private Boolean isChargeback;
    private String orderId;
    private String applicationDomain;
}

response：響應(yīng)類，后端響應(yīng)給前端的字段

DisputeMerchantManageResponse：后端通過DisputeMerchantManageRequest字段查詢數(shù)據(jù)庫返回查詢出的數(shù)據(jù)

@Data
public class DisputeMerchantManageResponse {
    private Long disputeId;
    private Integer disputeStatus;
    private Integer disputeType;
    private String disputeContent;
    private String merchantNo;
    private String uniqueId;
    private String transactionId;
    private Boolean isReply;
    private Boolean isChargeback;
    private String billingEmail;
    private Date disputeCreatedAt;
    private Date paymentCreatedAt;
    private String orderId;
    private String applicationDomain;
}

PageResult類

@Data
@SuperBuilder
@NoArgsConstructor
@AllArgsConstructor
public class PageResult<T> implements Serializable {
    @ApiModelProperty("總記錄數(shù)")
    private Integer total;
    private Integer pageNo;
    private Integer pageSize;
    private Integer totalPage;
    @ApiModelProperty("列表數(shù)據(jù)")
    @Builder.Default
    private List<T> items = Collections.emptyList();
    public static <T> PageResult<T> toPage(IPage<T> page) {
        PageResult<T> result = new PageResult<>();
        result.setItems(page.getRecords());
        result.setTotal((int) page.getTotal());
        result.setPageNo((int) page.getCurrent());
        result.setPageSize((int) page.getSize());
        result.setTotalPage(page.getTotal() % page.getSize() == 0 ?
                (int) (page.getTotal() / page.getSize()) : (int) (page.getTotal() / page.getSize() + 1));
        return result;
    }
    public static <T> PageResult<T> toPage(IPage<?> page, List<T> list) {
        PageResult<T> result = new PageResult<>();
        result.setItems(list);
        result.setTotal((int) page.getTotal());
        result.setPageNo((int) page.getCurrent());
        result.setPageSize((int) page.getSize());
        result.setTotalPage(page.getTotal() % page.getSize() == 0 ?
                (int) (page.getTotal() / page.getSize()) : (int) (page.getTotal() / page.getSize() + 1));
        return result;
    }
    public static <T> PageResult<T> toPage(PageResult<?> res, List<T> list) {
        PageResult<T> result = new PageResult<>();
        BeanUtils.copyProperties(res, result);
        result.setItems(list);
        return result;
    }
}
