Controller接口编写
@PostMapping("merchant/manage") public Result<PageResult<DisputeMerchantManageResponse>> merchantDisputeManage(@RequestBody DisputeMerchantManageRequest request) { return Result.succ(merchantDisputeFacade.merchantDisputeManage(request)); }
Result
返回给前端的字段:VO>: @RequestBody DisputeMerchantManageRequest request:
接收前端传递的JSON数据:BOmerchantDisputeFacade.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 manageBOList
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();
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.
创建了用于构建builder(): 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_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: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
@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 转换成 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: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
@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: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
@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类
@Data
@SuperBuilder
@NoArgsConstructor
@AllArgsConstructor
public 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.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;
}
}
