商务网站建设试卷软文推广的优点

因为迁移的生产环境，在新的服务器发生了之前没有遇到的问题，这种问题是在异步文件上传的时候才会出现
错误信息如下

16:17:50.009 ERROR c.w.einv.minio.service.impl.MinioFileServiceImpl - 文件上传错误!
java.io.FileNotFoundException: /application/acc-statement-server/tmp/work/Tomcat/localhost/ROOT/upload_82aa4ea1_6e02_47b7_8d1f_26e9bd20c0ca_00000005.tmp (No such file or directory)at java.io.FileInputStream.open0(Native Method)at java.io.FileInputStream.open(FileInputStream.java:195)at java.io.FileInputStream.<init>(FileInputStream.java:138)at org.apache.tomcat.util.http.fileupload.disk.DiskFileItem.getInputStream(DiskFileItem.java:198)at org.apache.catalina.core.ApplicationPart.getInputStream(ApplicationPart.java:100)at org.springframework.web.multipart.support.StandardMultipartHttpServletRequest$StandardMultipartFile.getInputStream(StandardMultipartHttpServletRequest.java:254)at com.whty.einv.minio.service.impl.MinioFileServiceImpl.upload(MinioFileServiceImpl.java:123)at com.whty.acc.statement.dubbo.task.FileHandlerTaskImpl.handleIndividualTaxFile(FileHandlerTaskImpl.java:72)at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method)

参考【报错记录】SpringBoot中MultipartFile上传报/tmp/tomcat.***.tmp (No such file or directory)
/tmp/tomcat /work/Tomcat/localhost/RooT/upload_*****.tmp (No such file or directory)
下面是异步操作的代码,注意这里的File要转换为java.io.File

    @Async@Overridepublic void handleIndividualTaxFile(String dataId, File file, File pic) {log.info("===>异步处理更新个税申报状态文件开始<===");AccIndividualTaxDeclare individualTaxDeclare = new AccIndividualTaxDeclare();log.info("===>A1.处理综合所得预扣预缴表文件开始<===");// 处理综合所得预扣预缴表文件if (!CheckEmptyUtil.isEmpty(file)) {log.info("RPA提供的file文件大小:{},文件名{}", file.getTotalSpace(), file.getName());String withholdingFormPath = INDIVIDUAL_TAX_FOLDER + dataId + CommonSettingConstants.Split.SLASH + file.getName();minioFileService.upload(bucketName, file, withholdingFormPath);// 获取文件的完整路径String withholdingFormUrl = this.getHttpUrl(endpointO, bucketName, withholdingFormPath);individualTaxDeclare.setWithholdingFormUrl(withholdingFormUrl);log.info("综合所得预扣预缴表url:{}", withholdingFormUrl);

所以需要在前面做更正

  @WebLog@ApiOperation("报税状态更新(新RPA调用)")@PostMapping("/status/new")public ResponseResult<?> updateTaxDeclareStatusNew(MultipartFile file, MultipartFile pic,@Validated UpdateTaxReq updateTaxReq, BindingResult bindingResult) {// 字段非空和规则的基本校验if (bindingResult.hasErrors()) {List<FieldError> fieldErrors = bindingResult.getFieldErrors();fieldErrors.forEach(e -> log.error("校验未通过字段:{},原因:{}", e.getField(), e.getDefaultMessage()));return new ResponseResult<>(false, Objects.requireNonNull(bindingResult.getFieldError()).getDefaultMessage());}log.info("新RPA调用报税状态更新接口请求参数:{}", JSON.toJSONString(updateTaxReq));ResponseResult<?> rs;try {// 文件File excelFile = null;if (!CheckEmptyUtil.isEmpty(file)){String fileName = file.getOriginalFilename();String prefix = fileName.substring(fileName.lastIndexOf("."));excelFile = File.createTempFile(System.currentTimeMillis() + "", prefix);file.transferTo(excelFile);}// 图片File picFile = null;if (!CheckEmptyUtil.isEmpty(pic)){String picFileName = pic.getOriginalFilename();String picPrefix = picFileName.substring(picFileName.lastIndexOf("."));picFile = File.createTempFile(System.currentTimeMillis() + "", picPrefix);pic.transferTo(picFile);}//taxDeclarationService.updateTaxDeclareStatusForRpa(updateTaxReq, excelFile, picFile);

中间还有一个代码,可以看到

 @Overridepublic void updateTaxDeclareStatusForRpa(UpdateTaxReq updateTaxReq, File file, File pic) {// 参数String dataId = updateTaxReq.getDataId();String reportCode = updateTaxReq.getReportCode();String taxType = updateTaxReq.getTaxType();{// 个税AccIndividualTaxDeclare individualTaxDeclare = new AccIndividualTaxDeclare();switch (reportCode) {case StatementConstants.RpaReturnCode.DECLARE_SUCCESS:
individualTaxDeclare.setDeclareStatus(StatementConstants.DeclareStatus.DECLARED_SUCCESS);fileHandlerTask.handleIndividualTaxFile(dataId, file, pic);

注意spring中tomcat的路径配置,当controller文件生成后，会把文件暂存在/application/acc-statement-server/tmp中
