前言
这段时间的项目中需要导出动态表格。
根据所选的参数导出对应的字段内容
下图所示选择下面几个tab页就需要导出对应的表头字段
下面为具体实现的效果。表头样式可以通过EasyExcel 提供的方法自定义。
具体实现
主要是通过 传入 exportItem 这个条件来决定导出的事项。
下附实现代码
public boolean export(QueryBO queryBo) throws CustomException {
List<Integer> exportItem = queryBo.getExportItem();
List<BankAccountOverviewVO> bankAccountOverviewList =
accountOverviewList(queryBo, new PageInfoVo());
// 动态创建表头
List<List<String>> headList = new ArrayList<>();
// 组装数据
List<List<Object>> dataList = new ArrayList<>();
// 表头合并的逻辑
List<CellRangeAddress> cellRangeAddressList = new ArrayList<>();
// 组装账户信息总览 导出数据
builidAccountOverviewExportData(
exportItem, bankAccountOverviewList, headList, dataList, cellRangeAddressList);
String fileName = "信息总览.xlsx";
// 调用EasyExcel 方法输出文件流
try {
HttpServletResponse response = ServletUtils.getResponse();
response.setContentType("application/msexcel;charset=utf-8");
response.setHeader(
"content-disposition", "attachment; filename=" + URLEncoder.encode(fileName, "utf-8"));
OutputStream out = response.getOutputStream();
EasyExcel.write(out)
.head(headList) // 设置表头数据
.registerWriteHandler(new SimpleColumnWidthStyleStrategy(25)) // excel 样式设置
.autoCloseStream(Boolean.TRUE) // 自动关闭文件流
.sheet("信息总览")
.doWrite(dataList); // 数据list
// 开始导出
} catch (Exception e) {
LoggerUtils.error(e.getMessage());
return false;
}
return true;
}
数据组装方法
builidAccountOverviewExportData
主要实现的原理是通过List<Integer> exportItem 来判断需要导出的tab块。
其中使用了 getApiModelName(OverviewBankBookOcceVO.class); 方法映射对象的字段名进行快捷组装。
private void builidAccountOverviewExportData(
List<Integer> exportItem,
List<BankAccountOverviewVO> bankAccountOverviewList,
List<List<String>> headList,
List<List<Object>> dataList,
List<CellRangeAddress> cellRangeAddressList) {
// --------------表头拼接-------------
// 账户信息
List<String> bankBookHead = new ArrayList<>();
bankBookHead.add("企业主体编码");
bankBookHead.add("企业主体名称");
for (String head : bankBookHead) {
List<String> bankBookHeadTitle = new ArrayList<>();
bankBookHeadTitle.add(head);
headList.add(bankBookHeadTitle);
}
// 字段下标！！！！！！！！！！
int index = 13;
if (CollectionUtils.isNotEmpty(exportItem)) {
// 账面发生额
if (exportItem.contains(BankAccountOverviewExportTypeEnum.BANK_BOOK_OCCE.getValue())) {
List<String> apiModelNameList = getApiModelName(OverviewBankBookOcceVO.class);
for (String apiModelName : apiModelNameList) {
List<String> bankBookOccHeadTitle = new ArrayList<>();
bankBookOccHeadTitle.add("账面发生额");
bankBookOccHeadTitle.add(apiModelName);
headList.add(bankBookOccHeadTitle);
}
// // 需要合并的表头位置 （起始行，结束行，起始列，结束列）
// int size = apiModelNameList.size();
// CellRangeAddress cellRangeAddress = new CellRangeAddress(0, 0, index, index + size -
// 1);
// cellRangeAddressList.add(cellRangeAddress);
// index += size;
}
// 发生额调节表
if (exportItem.contains(BankAccountOverviewExportTypeEnum.OCC_ADJUSTMENT.getValue())) {
List<String> apiModelNameList = getApiModelName(OverviewOccAdjustmentVO.class);
for (String apiModelName : apiModelNameList) {
List<String> occAdjustmentInfoHeadTitle = new ArrayList<>();
occAdjustmentInfoHeadTitle.add("发生额调节表");
occAdjustmentInfoHeadTitle.add(apiModelName);
headList.add(occAdjustmentInfoHeadTitle);
}
}
// 网银流水
if (exportItem.contains(BankAccountOverviewExportTypeEnum.EBANK_FLOW.getValue())) {
List<String> apiModelNameList = getApiModelName(OverviewEbankFlowVO.class);
for (String apiModelName : apiModelNameList) {
List<String> ebankFlowHeadTitle = new ArrayList<>();
ebankFlowHeadTitle.add("网银流水");
ebankFlowHeadTitle.add(apiModelName);
headList.add(ebankFlowHeadTitle);
}
}
// 核对余额
if (exportItem.contains(BankAccountOverviewExportTypeEnum.RECONCILE_BALANCE.getValue())) {
List<String> apiModelNameList = getApiModelName(OverviewReconcileBalanceVO.class);
for (String apiModelName : apiModelNameList) {
List<String> reconcileBalancesHeadTitle = new ArrayList<>();
reconcileBalancesHeadTitle.add("核对余额");
reconcileBalancesHeadTitle.add(apiModelName);
headList.add(reconcileBalancesHeadTitle);
}
// 需要合并的表头位置 （起始行，结束行，起始列，结束列）
int size = apiModelNameList.size();
CellRangeAddress cellRangeAddress = new CellRangeAddress(0, 0, index, index + size - 1);
cellRangeAddressList.add(cellRangeAddress);
index += size;
}
// 双向核对结果
if (exportItem.contains(BankAccountOverviewExportTypeEnum.CHECK_RESULT.getValue())) {
List<String> apiModelNameList = getApiModelName(OverviewCheckResultVO.class);
for (String apiModelName : apiModelNameList) {
List<String> checkResultHeadTitle = new ArrayList<>();
checkResultHeadTitle.add("双向核对结果");
checkResultHeadTitle.add(apiModelName);
headList.add(checkResultHeadTitle);
}
}
}
// ----------------组装数据-------------
for (BankAccountOverviewVO bankAccountOverview : bankAccountOverviewList) {
List<Object> data = new ArrayList<>();
// 账户信息总览
data.add(bankAccountOverview.getCompanyId());
data.add(bankAccountOverview.getCompanyName());
String checkPlanFlag = bankAccountOverview.getCheckPlanFlag();
if (StringUtils.isNotEmpty(checkPlanFlag)) {
checkPlanFlag = checkPlanFlag.replaceAll("0", "是");
checkPlanFlag = checkPlanFlag.replaceAll("1", "否");
}
data.add(checkPlanFlag);
data.add(bankAccountOverview.getNoCheckReason());
// -------动态表格数据组装-----
if (CollectionUtils.isNotEmpty(exportItem)) {
// 账面发生额
if (exportItem.contains(BankAccountOverviewExportTypeEnum.BANK_BOOK_OCCE.getValue())) {
data.add(bankAccountOverview.getBankBookOccInfo().getOpenBalance());
data.add(bankAccountOverview.getBankBookOccInfo().getCurrentIssueAdd());
data.add(bankAccountOverview.getBankBookOccInfo().getCurrentIssueReduce());
data.add(bankAccountOverview.getBankBookOccInfo().getBalance());
data.add(bankAccountOverview.getBankBookOccInfo().getOpenBalanceF());
data.add(bankAccountOverview.getBankBookOccInfo().getCurrentIssueAddF());
data.add(bankAccountOverview.getBankBookOccInfo().getCurrentIssueReduceF());
data.add(bankAccountOverview.getBankBookOccInfo().getBalanceF());
}
// 发生额调节表
if (exportItem.contains(BankAccountOverviewExportTypeEnum.OCC_ADJUSTMENT.getValue())) {
data.add(bankAccountOverview.getOccAdjustmentInfo().getCurrentIssueAdd());
data.add(bankAccountOverview.getOccAdjustmentInfo().getCurrentIssueReduce());
}
// 网银流水
if (exportItem.contains(BankAccountOverviewExportTypeEnum.EBANK_FLOW.getValue())) {
data.add(bankAccountOverview.getEbankFlowInfo().getOpenBalance());
data.add(bankAccountOverview.getEbankFlowInfo().getCurrentIssueAdd());
data.add(bankAccountOverview.getEbankFlowInfo().getCurrentIssueReduce());
data.add(bankAccountOverview.getEbankFlowInfo().getBalance());
}
// 核对余额
if (exportItem.contains(BankAccountOverviewExportTypeEnum.RECONCILE_BALANCE.getValue())) {
data.add(bankAccountOverview.getReconcileBalances().getBalanceVerify());
data.add(bankAccountOverview.getReconcileBalances().getDebitOccFVerify());
data.add(bankAccountOverview.getReconcileBalances().getCreditOccFVerify());
data.add(bankAccountOverview.getReconcileBalances().getNetAmountVerify());
}
// 双向核对结果
if (exportItem.contains(BankAccountOverviewExportTypeEnum.CHECK_RESULT.getValue())) {
data.add(bankAccountOverview.getCheckResult().getDebitOccF());
data.add(bankAccountOverview.getCheckResult().getCreditOccF());
data.add(bankAccountOverview.getCheckResult().getDebitRatio());
data.add(bankAccountOverview.getCheckResult().getCreditRatio());
data.add(bankAccountOverview.getCheckResult().getUntreatedProject());
data.add(bankAccountOverview.getCheckResult().getExceptionProject());
}
}
dataList.add(data);
}
}
getApiModelName 方法代码如下，因为项目引入了 swagger 所以数据接口对象都会使用到 @ApiModelProperty 注解 如下图所示。通过反射获取实体类的对应属性的注解名称list。文章来源：https://www.toymoban.com/news/detail-479433.html
@Data
@ApiModel(value = "vo对象", description = "vo对象")
public class OverviewBankBookOcceVO {
@ApiModelProperty(value = "银行账号")
private String bankAccount;
@ApiModelProperty("期初余额(原币)")
private BigDecimal openBalance;
}
/**
* @description 获取对象中 api 注解的名称
* @params [object]
* @return
*/
private List<String> getApiModelName(Object object) {
Class<T> aClass = (Class<T>) object;
Field[] fields = aClass.getDeclaredFields();
List<String> apiModelName = new ArrayList<>();
for (Field field : fields) {
ApiModelProperty annotation = field.getAnnotation(ApiModelProperty.class);
String value = annotation.value();
if (field.getName().equals("bankAccount")) {
continue;
}
apiModelName.add(value);
}
return apiModelName;
}
