代码实现

Controller接口编写

 @PostMapping("merchant/manage") public Result<PageResult<DisputeMerchantManageResponse>> merchantDisputeManage(@RequestBody DisputeMerchantManageRequest request) { return Result.succ(merchantDisputeFacade.merchantDisputeManage(request)); }
  • Result<PageResult>:返回给前端的字段：VO
  • @RequestBody DisputeMerchantManageRequest request:接收前端传递的JSON数据：BO
  • merchantDisputeFacade.merchantDisputeManage(request):调用Service的merchantDisputeManage方法，传递接受的参数request

Service编写

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):将DisputeMerchantManageRequest对象 request 转换为 DisputeMerchantManageBO对象 manageBO
  • List list = merchantDisputeService.merchantDisputeManage(manageBO):调用merchantDisputeService中的merchantDisputeManage方法，传递manageBO作为参数，然后获取一个List类型的结果列表
 PageResult<DisputeMerchantManageResponse> pageResult = PageResult. <DisputeMerchantManageResponse>builder() .pageNo(Integer.parseInt(request.getPageNo())).pageSize(Integer.parseInt(request.getPageSize())).total(merchantDisputeService.merchantDisputeManageCount(manageBO)) .items(list).build();
  • PageResult:泛型类封装分页查询结果，包含页面信息、页码、每页条目数、总记录数以及当前页面的数据项列表
  • PageResult.builder():创建了用于构建PageResult对象的构造器；后续代码可以通过该构造器设置分页信息、总记录数和当前页面的数据项列表，最终得到一个完整的PageResult对象
  • .pageNo(Integer.parseInt(request.getPageNo())):设置PageResult对象的当前页码
  • .pageSize(Integer.parseInt(request.getPageSize())):设置PageResult对象的每页条目数
  • .total(merchantDisputeService.merchantDisputeManageCount(manageBO)):设置PageResult对象的总记录数
  • .items(list).build():设置PageResult对象的数据项列表，并完成构建PageResult对象
  • .items(list):获取的数据项列表list设置为PageResult对象的数据项列表属性
  • .build():完成PageResult对象的构建，最终得到一个完整的PageResult对象

Service编写

MerchantDisputeService.java

public List<DisputeMerchantManageResponse> merchantDisputeManage(DisputeMerchantManageBO disputeMerchantManageBO) {Merchant merchant = AuthContextHolder.getLoginMerchant();disputeMerchantManageBO.setMerchantNo(merchant.getMerchantNo());return merchantDisputeMapper.merchantDisputeManage(disputeMerchantManageBO);}
  • Merchant merchant = AuthContextHolder.getLoginMerchant():通过AuthContextHolder获取当前登录的商家（Merchant）对象；AuthContextHolder：用于在当前线程的上下文中存储和管理认证信息
  • disputeMerchantManageBO.setMerchantNo(merchant.getMerchantNo()):获取merchant中的MerchantNo(商户号)，并存储在disputeMerchantManageBO中
  • merchantDisputeMapper.merchantDisputeManage(disputeMerchantManageBO):调用Mapper层merchantDisputeManage方法将disputeMerchantManageBO作为参数传递给Mapper

Mapper

List<DisputeMerchantManageResponse> merchantDisputeManage(DisputeMerchantManageBO disputeMerchantManageBO);

Mapper.xml

  • 通过联表查询，查询merchant_dispute和transaction_order表对应字段，通过对disputeMerchantManageBO字段传入的条件动态生成查询语句，并按照创建时间进行降序排序，最后返回指定分页范围内的结果
<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_iduniqueId,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_idfrom merchant_dispute md,transaction_order owhere 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 desclimit #{limit} offset #{offset}</select>

BO：对前端传递参数进行接收处理

  • 使用DisputeMerchantManageBO处理request的主要目的是为了在业务逻辑层（Service层）中更好地封装业务逻辑和数据处理
@Datapublic 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 转换成 BOpublic 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：请求类，前端向后端请求的字段

DisputeMerchantManageRequest.java

DisputeMerchantManageRequest：字段对应搜索框需要搜索的字段

@Datapublic 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：响应类，后端响应给前端的字段

DisputeMerchantManageResponse：后端通过DisputeMerchantManageRequest字段查询数据库返回查询出的数据

@Datapublic 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类

@Data@SuperBuilder@NoArgsConstructor@AllArgsConstructorpublic class PageResult<T> implements Serializable {@ApiModelProperty("总记录数")private Integer total;private Integer pageNo;private Integer pageSize;private Integer totalPage;@ApiModelProperty("列表数据")@Builder.Defaultprivate 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;}}
