  如何通过自定义支持excel导出的动态表头

  介绍 本文需要阅读过前置文档如何自定义Excel导出功能，动态表头的功能在前置文档的基础上做的进一步扩展，本文未提到的部分都参考这个前置文档。 在日常的业务开发中，我们在导出的场景会遇到需要设置动态表头的场景，比如统计商品在最近1个月的销量，固定表头列为商品的名称等基础信息，动态表头列为最近一个月的日期，在导出的时候设置每个日期的销量，本文将通过此业务场景提供示例代码。 1.自定义导出任务模型 package pro.shushi.pamirs.demo.api.model; import pro.shushi.pamirs.file.api.model.ExcelExportTask; import pro.shushi.pamirs.meta.annotation.Model; @Model.model(DemoItemDynamicExcelExportTask.MODEL_MODEL) @Model(displayName = "商品-Excel动态表头导出任务") public class DemoItemDynamicExcelExportTask extends ExcelExportTask { public static final String MODEL_MODEL = "demo.DemoItemDynamicExcelExportTask"; } 2.自定义导出任务处理数据的扩展点 package pro.shushi.pamirs.demo.core.excel.exportdemo.extPoint; import org.springframework.stereotype.Component; import pro.shushi.pamirs.core.common.FetchUtil; import pro.shushi.pamirs.core.common.cache.MemoryIterableSearchCache; import pro.shushi.pamirs.demo.api.model.DemoItem; import pro.shushi.pamirs.file.api.config.FileConstant; import pro.shushi.pamirs.file.api.context.ExcelDefinitionContext; import pro.shushi.pamirs.file.api.enmu.ExcelTemplateTypeEnum; import pro.shushi.pamirs.file.api.entity.EasyExcelCellDefinition; import pro.shushi.pamirs.file.api.extpoint.impl.ExcelExportSameQueryPageTemplate; import pro.shushi.pamirs.file.api.model.ExcelExportTask; import pro.shushi.pamirs.file.api.model.ExcelWorkbookDefinition; import pro.shushi.pamirs.file.api.util.ExcelFixedHeadHelper; import pro.shushi.pamirs.file.api.util.ExcelHelper; import pro.shushi.pamirs.file.api.util.ExcelTemplateInit; import pro.shushi.pamirs.framework.common.entry.TreeNode; import pro.shushi.pamirs.meta.annotation.ExtPoint; import pro.shushi.pamirs.meta.api.CommonApiFactory; import pro.shushi.pamirs.meta.api.core.orm.ReadApi; import pro.shushi.pamirs.meta.api.core.orm.systems.relation.RelationReadApi; import pro.shushi.pamirs.meta.api.dto.config.ModelConfig; import pro.shushi.pamirs.meta.api.dto.config.ModelFieldConfig; import pro.shushi.pamirs.meta.api.session.PamirsSession; import pro.shushi.pamirs.meta.enmu.TtypeEnum; import pro.shushi.pamirs.meta.util.FieldUtils; import java.util.*; @Component public class DemoItemDynamicExportExtPoint extends ExcelExportSameQueryPageTemplate<DemoItem> implements ExcelTemplateInit { public static final String TEMPLATE_NAME ="商品动态导出"; @Override public List<ExcelWorkbookDefinition> generator() { ExcelFixedHeadHelper excelFixedHeadHelper = ExcelHelper.fixedHeader(DemoItem.MODEL_MODEL,TEMPLATE_NAME) .createBlock(TEMPLATE_NAME, DemoItem.MODEL_MODEL) .setType(ExcelTemplateTypeEnum.EXPORT); return Collections.singletonList(excelFixedHeadHelper.build()); } public static void buildHeader(ExcelFixedHeadHelper excelFixedHeadHelper) { excelFixedHeadHelper.addColumn("name","名称") .addColumn("cateName","类目") .addColumn("searchFrom","搜索来源") .addColumn("description","描述") .addColumn("itemPrice","单价") .addColumn("inventoryQuantity","库存"); } @Override @ExtPoint.Implement(expression = "context.model == \"" + DemoItem.MODEL_MODEL+"\" && context.name == \"" +TEMPLATE_NAME+"\"" ) public List<Object> fetchExportData(ExcelExportTask exportTask, ExcelDefinitionContext context) { List<Object> result = super.fetchExportData(exportTask,context); Object block = result.get(0); if (block instanceof ArrayList) { ((List<Object>) block).forEach(o -> { if (o instanceof DemoItem) { DemoItem item = (DemoItem) o; // TODO 设置动态表头部分字段的值 item.get_d().put("2024-09-10", "1111"); item.get_d().put("2024-09-11", "2222"); }…

  自定义数据权限拦截处理

  业务场景 公司给员工对哪些模块有访问权限，这个时候就需要在员工访问模块表的时候做数据过滤， 解决方案 我们可以通过平台提供的数据过滤占位符解决这个问题，新建一条数据行权限，过滤语句条件是占位符，再编写占位符的解析逻辑 1.初始化权限基础数据 package pro.shushi.pamirs.demo.core.init; import com.google.common.collect.Lists; import org.springframework.core.annotation.Order; import org.springframework.stereotype.Component; import pro.shushi.pamirs.auth.api.constants.AuthConstants; import pro.shushi.pamirs.auth.api.enmu.AuthGroupTypeEnum; import pro.shushi.pamirs.auth.api.enmu.PermissionDataSourceEnum; import pro.shushi.pamirs.auth.api.enmu.PermissionTypeEnum; import pro.shushi.pamirs.auth.api.model.AuthGroup; import pro.shushi.pamirs.auth.api.model.AuthRole; import pro.shushi.pamirs.auth.api.model.ResourcePermission; import pro.shushi.pamirs.boot.base.model.UeModule; import pro.shushi.pamirs.boot.common.api.command.AppLifecycleCommand; import pro.shushi.pamirs.boot.common.api.init.InstallDataInit; import pro.shushi.pamirs.boot.common.api.init.UpgradeDataInit; import pro.shushi.pamirs.demo.api.DemoModule; import pro.shushi.pamirs.demo.core.placeholder.EmployeeModulePlaceholder; import pro.shushi.pamirs.framework.common.utils.ObjectUtils; import pro.shushi.pamirs.meta.annotation.fun.extern.Slf4j; import pro.shushi.pamirs.meta.domain.module.ModuleDefinition; import java.util.Collections; import java.util.List; @Slf4j @Component @Order(0) public class DemoModuleBizInit implements InstallDataInit, UpgradeDataInit { @Override public List<String> modules() { return Collections.singletonList(DemoModule.MODULE_MODULE); } @Override public int priority() { return 0; } @Override public boolean init(AppLifecycleCommand command, String version) { this.initAuth(); return true; } @Override public boolean upgrade(AppLifecycleCommand command, String version, String existVersion) { this.initAuth(); return true; } private void initAuth() { AuthGroup authGroup = new AuthGroup(); authGroup.setName("测试权限组") .setDisplayName("测试权限组") .setType(AuthGroupTypeEnum.RUNTIME) .setActive(true); authGroup.createOrUpdate(); AuthRole authRole = new AuthRole(); authRole.setCode("TEST_ROLE_1") .setName("测试角色") .setRoleTypeCode(AuthConstants.ROLE_SYSTEM_TYPE_CODE) .setPermissionDataSource(PermissionDataSourceEnum.CUSTOM) .setActive(true); authRole.createOrUpdate(); authRole.setGroups(Lists.newArrayList(authGroup)); authRole.fieldSave(AuthRole::getGroups); ResourcePermission authPermission = new ResourcePermission(); authPermission.setName("测试模块权限过滤") .setDomainExp(EmployeeModulePlaceholder.PLACEHOLDER) .setModel(ModuleDefinition.MODEL_MODEL) .setPermRead(true) .setPermRun(true) .setPermissionType(PermissionTypeEnum.ROW) .setPermissionDataSource(PermissionDataSourceEnum.CUSTOM) .setCanShow(true) .setActive(true); ResourcePermission authPermission2 = ObjectUtils.clone(authPermission); authPermission2.setName("测试ue模块权限过滤").setModel(UeModule.MODEL_MODEL); authGroup.setPermissions(Lists.newArrayList(authPermission, authPermission2)); authGroup.fieldSave(AuthGroup::getPermissions); } } 这里演示的module表比较特殊，需要同时设置ModuleDefinition和UeModule这2个模型做数据过滤 2.编写占位符拦截替换逻辑 package pro.shushi.pamirs.demo.core.placeholder; import org.springframework.stereotype.Component; import pro.shushi.pamirs.user.api.AbstractPlaceHolderParser; @Component public class EmployeeModulePlaceholder extends AbstractPlaceHolderParser { public static final String PLACEHOLDER = "${employeeModulePlaceholder}"; protected String value() { // TODO…

  DsHint(指定数据源)和BatchSizeHint(指定批次数量)

  概述和使用场景 DsHintApi ，强制指定数据源， BatchSizeHintApi ，强制指定查询批量数量 API定义 DsHintApi public static DsHintApi model(String model/**模型编码*/) { // 具体实现 } public DsHintApi(Object dsKey/***数据源名称*/) { // 具体实现 } BatchSizeHintApi public static BatchSizeHintApi use(Integer batchSize) { // 具体实现 } 使用示例 1、【注意】代码中使用 try-with-resources语法; 否则可能会出现数据源错乱 2、DsHintApi使用示例包裹在try里面的所有查询都会强制使用指定的数据源 // 使用方式1： try (DsHintApi dsHintApi = DsHintApi.model(PetItem.MODEL_MODEL)) { List<PetItem> items = demoItemDAO.customSqlDemoItem(); PetShopProxy data2 = data.queryById(); data2.fieldQuery(PetShopProxy::getPetTalents); } // 使用方式2： try (DsHintApi dsHintApi = DsHintApi.use("数据源名称")) { List<PetItem> items = demoItemDAO.customSqlDemoItem(); PetShopProxy data2 = data.queryById(); data2.fieldQuery(PetShopProxy::getPetTalents); } 3、BatchSizeHintApi使用示例包裹在try里面的所有查询都会按照指定的batchSize进行查询 // 查询指定每次查询500跳 try (BatchSizeHintApi batchSizeHintApi = BatchSizeHintApi.use(500)) { PetShopProxy data2 = data.queryById(); data2.fieldQuery(PetShopProxy::getPetTalents); } // 查询指定不分页(batchSize=-1)查询。 请注意，你必须在明确不需要分页查询的情况下使用；如果数据量超大不分页可能会卡死。默认不指定分页数的情况下下平台会进行分页查询 try (BatchSizeHintApi batchSizeHintApi = BatchSizeHintApi.use(-1)) { PetShopProxy data2 = data.queryById(); data2.fieldQuery(PetShopProxy::getPetTalents); }

  Excel导入导出模板翻译

  导出翻译项 与翻译的导出全部翻译项类似，只是该操作目前没有加入到页面交互中，需要通过工具发起后端服务请求，拿到导入导出翻译Excel模版，添加模版翻译项。（查看路径：文件–导出任务） mutation { excelExportTaskMutation { createExportTask( data: { workbookDefinition: { model: "file.ExcelWorkbookDefinition" name: "excelLocationTemplate" } } ) { name } } } variables: { "path": "/file", "lang": "en-US" } 参数说明：（不在以下说明范围内的参数无需修改） variables.lang参数：用于指定翻译项的目标语言编码，与【资源】-【语言】中的编码一致。 导入翻译项 mutation { excelImportTaskMutation { createImportTask( data: { workbookDefinition: { model: "file.ExcelWorkbookDefinition" name: "excelLocationTemplate" } file: { url: "翻译项URL链接" } } ) { name } } } variables: { "path": "/file" } 参数说明： 将翻译项URL链接改为实际可访问的文件链接即可，可通过页面中任意文件上传的组件获取。
