今天遇到了一个问题，就是我使用开发框架自动生成了有关于数据库表中的数据（全部属性）的controller，service，Impl之类的，都是有关于数据库的表的实体类，但是我要传输的条件，和我要返回的条件不是数据库的那个实体类
需求：一个对应数据库中所有属性的实体类，一个输入的实体类，一个输出的实体类，完成分页查询

controller

public R getBigOthNppReportPageSimple(Page page, BigOthNppReport bigOthNppReport) {
IPage<BigOthNppReportSimple> bigOthNppReportPageSimple = bigOthNppReportService.getBigOthNppReportPageSimple(page, bigOthNppReport);
return R.ok(bigOthNppReportPageSimple);
}

service

IPage<BigOthNppReportSimple> getBigOthNppReportPageSimple(Page page, BigOthNppReport bigOthNppReport);

Impl

public IPage<BigOthNppReportSimple> getBigOthNppReportPageSimple(Page page, BigOthNppReport bigOthNppReport) {
Page<BigOthNppReport> page1 = new Page<>(page.getCurrent(), page.getSize());
LambdaQueryWrapper<BigOthNppReport> wrapper = new LambdaQueryWrapper<>();
wrapper.eq(Objects.nonNull(bigOthNppReport.getRptNd()),BigOthNppReport::getRptNd,bigOthNppReport.getRptNd())
.like(StrUtil.isNotBlank(bigOthNppReport.getPublishOrg()),BigOthNppReport::getPublishOrg,bigOthNppReport.getPublishOrg())
.like(StrUtil.isNotBlank(bigOthNppReport.getNppOrg()),BigOthNppReport::getNppOrg,bigOthNppReport.getNppOrg())
.orderByDesc(BigOthNppReport::getId);
Page<BigOthNppReport> pageList = page(page1, wrapper);
return pageList.convert(item -> BigOthNppReportSimple.builder()
.id(item.getId())
.rptNd(item.getRptNd())
.no(item.getNo())
.theme(item.getTheme())
.publishOrg(item.getPublishOrg())
.nppOrg(item.getNppOrg())
.crewNo(item.getCrewNo())
.reportDate(item.getReportDate())
.writeName(item.getWriteName())
.writeTime(item.getWriteTime())
.flag(item.getFlag())
.build());
}

Page<ProductCertificate> page = new Page<>(ibo.getPageIndex(), ibo.getPageSize());
LambdaQueryWrapper<ProductCertificate> wrapper = new LambdaQueryWrapper<>();
wrapper.eq(ProductCertificate::getType, ibo.getType())
.like(StrUtil.isNotBlank(ibo.getNumber()),ProductCertificate::getNumber, ibo.getNumber())
.eq(Objects.nonNull(ibo.getFactoryId()), ProductCertificate::getFactoryId, ibo.getFactoryId())
.like(StrUtil.isNotBlank(ibo.getUploadFileName()), ProductCertificate::getUploadFileName,ibo.getUploadFileName())
.like(StrUtil.isNotBlank(ibo.getName()), ProductCertificate::getName,ibo.getName())
.eq(Objects.nonNull(ibo.getSupplierId()), ProductCertificate::getSupplierId,ibo.getSupplierId())
.between(madeStartDateFlag && madeEndDateFlag, ProductCertificate::getMadeDate,madeStartDate,madeEndDate)
.like(StrUtil.isNotBlank(ibo.getLicense()), ProductCertificate::getLicense, ibo.getLicense())
.ge(beginDateFlag, ProductCertificate::getBeginDate, ibo.getBeginDate())
.le(validityDateFlag, ProductCertificate::getValidityDate, ibo.getValidityDate())
.eq(ProductCertificate::getDeleted, false).last(SqlConstant.ORDER_BY_DESC);
Page<ProductCertificate> pageList = page(page, wrapper);
return pageList.convert(item -> ProductCertificateBO.builder()
.id(item.getId())
.productCategory(item.getType())
.number(item.getNumber())
.name(item.getName())
.model(item.getModel())
.factoryId(item.getFactoryId())
.factoryName(factoryInfoService.getFactoryName(item.getFactoryId()))
.uploadFileName(item.getUploadFileName())
.supplierId(item.getSupplierId())
.supplierName(item.getSupplierName())
.license(item.getLicense())
.beginDate(item.getBeginDate())
.validityDate(item.getValidityDate())
.madeDate(item.getMadeDate())
.build());
