优化以下代码List<OnWorkingEmployeeVO> onWorkingEmployees = employeeApiServiceClient.getEmpInfoByCorpIdAndStaffIds(param.getCorpId(), strList.getList()); if (onWorkingEmployees == null || onWorkingEmployees.size() == 0){ return PageModel.of(0, null); } List<SalaryBillListOfPermits> salaryBillListOfPermitsList = new ArrayList<>(); for (OnWorkingEmployeeVO onWorkingEmployee : onWorkingEmployees) { Integer numbs = hrmSalaryBillRecordDAO.getCountByCorpIdAndUserId(param.getCorpId(), onWorkingEmployee.getUserId()); SalaryBillListOfPermits salaryBillListOfPermits = new SalaryBillListOfPermits(); salaryBillListOfPermits.setNumbs(numbs); salaryBillListOfPermits.setDeptName(onWorkingEmployee.getMainDeptName()); salaryBillListOfPermits.setJobNumber(onWorkingEmployee.getEmpJobNumber()); salaryBillListOfPermits.setPersonId(onWorkingEmployee.getUserId()); salaryBillListOfPermits.setPersonName(onWorkingEmployee.getName()); salaryBillListOfPermitsList.add(salaryBillListOfPermits); }

优化以下代码List<SalaryBillListOfPermits> salaryBillListOfPermitsList = new ArrayList<>(); for (OnWorkingEmployeeVO onWorkingEmployee : onWorkingEmployees) { Integer numbs = hrmSalaryBillRecordDAO.getCountByCorpIdAndUserId(param.getCorpId(), onWorkingEmployee.getUserId()); SalaryBillListOfPermits salaryBillListOfPermits = new SalaryBillListOfPermits(); salaryBillListOfPermits.setNumbs(numbs); salaryBillListOfPermits.setDeptName(onWorkingEmployee.getMainDeptName()); salaryBillListOfPermits.setJobNumber(onWorkingEmployee.getEmpJobNumber()); salaryBillListOfPermits.setPersonId(onWorkingEmployee.getUserId()); salaryBillListOfPermits.setPersonName(onWorkingEmployee.getName()); salaryBillListOfPermitsList.add(salaryBillListOfPermits); }

解释这段代码List params = programService.firstQuery();//查血常规 B超基本信息 List<Long> programIds = new ArrayList<>(); Map<Long, String> programName = new HashMap<>(); for (Program param : params) { programIds.add(param.getId()); programName.put(param.getId(), param.getName()); } PhysicalProgram program = new PhysicalProgram(); program.setProgramIds(programIds); program.setIdCard(physicalProgram.getIdCard()); List list = physicalProgramService.firstQuery(program);

这段代码主要是查询体检项目和体检人的信息，然后根据查询到的体检项目，将每个项目的id和名称存储到一个Map中，同时将项目的id存储到一个List中。接着创建一个体检方案的实例，并将之前查询到的项目id列表和体检人...

在 Postman 中，您可以按照以下步骤进行操作： 1. 点击请求的 Body 选项卡。 2. 选择 "form-data" 选项。 3. 在 "Key" 列中输入 "file"。 4. 在 "Value" 列中选择 "File" 类型，并选择要上传的文件。 5. 在 "Key" ...

最后，调用userLikeMapper的qryPage方法，使用param作为参数来检索数据，将结果存储在一个List<UserLike>类型的userLikeList变量中。通常情况下，count方法将从数据库或其他数据源中查询数据的总数量，并使用参数...

优化代码：/** * 批量删除仪器 * * @param ids 需要删除的仪器主键 * @return 结果 */ @Override @Transactional public int deleteGsApparatusByIds(Long[] ids) { List<GsApparatusExample> list = gsApparatusExampleMapper.selectByApparatusIds(ids); if (!CollectionUtils.isEmpty(list)) { gsApparatusExampleMapper.deleteBatchIds(list); } List<GsApparatusIndex> listIndex = gsApparatusIndexMapper.selectByApparatusIds(ids); if (!CollectionUtils.isEmpty(listIndex)) { for (GsApparatusIndex index : listIndex) { Long id = index.getId(); gsArticleMapper.deleteGsArticleByIndexId(id); } gsApparatusIndexMapper.deleteBatchIds(listIndex); } return gsApparatusMapper.deleteGsApparatusByIds(ids); }

这段代码中可以进行一些优化的地方如下： 1. 使用批量删除方法：可以将删除操作改为使用批量删除的方式，这样可以减少与数据库的交互次数，提高效率。可以使用gsApparatusMapper.deleteBatchIds(ids)方法来实现...

方法的返回类型是List<coreindex>。在该方法中，使用了@Autowired注解来将coreindexMapper注入到coreindexController中。coreindexMapper是一个接口，可能是用于与数据库进行交互的组件。通过@...

请在保持原有代码逻辑的情况下优化下以下代码，尽可能提升代码的可读性、可维护性、性能……，并给出优化的理由。public PageInfo<ContractorVO> getPage(ContractorParam param) { ContractorCondition condition = convert.toCondition(param); // 数据范围 this.authority(condition); PageUtils.startPage(); List<ContractorBO> bos = contractorMapper.getBosByCondition(condition); PageInfo pageInfo = new PageInfo<>(bos); pageInfo.setList(bos.stream().map(convert::toVO).toList()); return pageInfo; }

可以尝试对这段代码进行如下优化： 1. 对变量和方法名进行重命名，使其更容易理解，如将 getPage 改为 getContractorPage，将 condition 改为 contractorCondition，将 bos 改为 contractorBOs，将 pageInfo 改为 ...

@GetMapping("/wccsbList") private TableDataInfo getWccsbList(EmsRCall emsRCall){ List<EmsRCall> list = emsRCallService.selectWccsbList(emsRCall); return getDataTable(list); }表现层这样写前端应该怎么传数据

param1=value1¶m2=value2&emsRCall.param3=value3&emsRCall.param4=value4 其中，emsRCall.param3 和 emsRCall.param4 表示 emsRCall 对象中的属性，value3 和 value4 是对应的属性值。在后端的...

在<if>标签中，如果param的id属性不为空，则添加了一个id = #{param.id}的条件。第二个查询语句的id是"listQuery"，与第一个查询语句类似，不同之处在于它添加了更多的条件筛选和分页功能。除了id之外，它还检查了...

请解释以下代码的逻辑，请在代码中合适的地方增加注释。public PageInfo<ContractorVO> getPage(ContractorParam param) { ContractorCondition condition = convert.toCondition(param); // 数据范围 this.authority(condition); PageUtils.startPage(); List<ContractorBO> bos = contractorMapper.getBosByCondition(condition); PageInfo pageInfo = new PageInfo<>(bos); pageInfo.setList(bos.stream().map(convert::toVO).toList()); return pageInfo; }
