  查询时自定义排序字段和排序规则

  指定字段排序 平台默认排序字段，参考IdModel，按创建时间和ID倒序(ordering = "createDate DESC, id DESC") 方法1：模型指定排序 模型定义增加排序字段。@Model.Advanced(ordering = "xxxxx DESC, yyyy DESC") @Model.model(PetShop.MODEL_MODEL) @Model(displayName = "宠物店铺",summary="宠物店铺",labelFields ={"shopName"}) @Model.Code(sequence = "DATE_ORDERLY_SEQ",prefix = "P",size=6,step=1,initial = 10000,format = "yyyyMMdd") @Model.Advanced(ordering = "createDate DESC") public class PetShop extends AbstractDemoIdModel { public static final String MODEL_MODEL="demo.PetShop"; // ………… } 方法2：Page查询中可以自定排序规则 API参考 pro.shushi.pamirs.meta.api.dto.condition.Pagination#orderBy public <G, R> Pagination<T> orderBy(SortDirectionEnum direction, Getter<G, R> getter) { if (null == getSort()) { setSort(new Sort()); } getSort().addOrder(direction, getter); return this; } 具体示例 @Function.Advanced(type= FunctionTypeEnum.QUERY) @Function.fun(FunctionConstants.queryPage) @Function(openLevel = {FunctionOpenEnum.API}) public Pagination<PetShop> queryPage(Pagination<PetShop> page, IWrapper<PetShop> queryWrapper){ page.orderBy(SortDirectionEnum.DESC, PetShop::getCreateDate); page = new PetShop().queryPage(page, queryWrapper); return page; } 方法3：查询的wapper中指定 API参考：pro.shushi.pamirs.framework.connectors.data.sql.AbstractWrapper#orderBy @Override public Children orderBy(boolean condition, boolean isAsc, R… columns) { if (ArrayUtils.isEmpty(columns)) { return typedThis; } SqlKeyword mode = isAsc ? ASC : DESC; for (R column : columns) { doIt(condition, ORDER_BY, columnToString(column), mode); } return typedThis; } 具体示例 public List<PetShop> queryList(String name) { List<PetShop> petShops = Models.origin().queryListByWrapper( Pops.<PetShop>lambdaQuery().from(PetShop.MODEL_MODEL) .orderBy(true, true, PetShop::getCreateDate) .orderBy(true, true, PetShop::getId) .like(PetShop::getShopName, name)); return petShops; } 设置查询不排序 方法1：关闭平台默认排序字段，设置模型的ordering，改成：ordering = "1=1" 模型定义增加排序字段。@Model.Advanced(ordering = "1=1") @Model.model(PetShop.MODEL_MODEL) @Model(displayName = "宠物店铺",summary="宠物店铺",labelFields ={"shopName"}) @Model.Code(sequence = "DATE_ORDERLY_SEQ",prefix = "P",size=6,step=1,initial = 10000,format = "yyyyMMdd") @Model.Advanced(ordering =…

  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"); }…

  如何重写获取首页的方法

  介绍 用户登录成功后或者访问网页不带任何路由参数的时候前端会请求全局的首页的视图动作viewAction配置，然后跳转到该视图动作viewAction 方案 我们可以通过在该方法的后置hook自定义获取首页的逻辑，下面以按角色跳转不同首页的需求示例 package pro.shushi.pamirs.demo.core.hook; import org.apache.commons.collections4.CollectionUtils; import org.springframework.stereotype.Component; import pro.shushi.pamirs.auth.api.model.AuthRole; import pro.shushi.pamirs.boot.base.enmu.BaseExpEnumerate; import pro.shushi.pamirs.boot.base.model.ViewAction; import pro.shushi.pamirs.boot.web.loader.PageLoadAction; import pro.shushi.pamirs.demo.api.model.DemoItemCategory; import pro.shushi.pamirs.demo.api.model.DemoItemLabel; import pro.shushi.pamirs.meta.annotation.Hook; import pro.shushi.pamirs.meta.api.CommonApiFactory; import pro.shushi.pamirs.meta.api.core.faas.HookAfter; import pro.shushi.pamirs.meta.api.dto.fun.Function; import pro.shushi.pamirs.meta.api.session.PamirsSession; import pro.shushi.pamirs.meta.common.exception.PamirsException; import pro.shushi.pamirs.user.api.model.PamirsUser; import java.util.List; import java.util.stream.Collectors; @Component public class DemoHomepageHook implements HookAfter { private static final String TEST_ROLE_CODE_01 = "ROLE_1211"; private static final String TEST_ROLE_CODE_02 = "ROLE_1211_1"; @Override @Hook(module = {"base"}, model = {ViewAction.MODEL_MODEL}, fun = {"homepage"}) public Object run(Function function, Object ret) { if (ret == null) { return null; } ViewAction viewAction = getViewActionByCurrentRole(); if (viewAction != null) { ViewAction retNew = CommonApiFactory.getApi(PageLoadAction.class).load(viewAction); ViewAction viewActionRet = (ViewAction) ((Object[]) ret)[0]; viewActionRet.set_d(retNew.get_d()); } return ret; } protected ViewAction getViewActionByCurrentRole() { try { PamirsUser user = new PamirsUser(); user.setId(PamirsSession.getUserId()); user.fieldQuery(PamirsUser::getRoles); List<AuthRole> roles = user.getRoles(); if (CollectionUtils.isNotEmpty(roles)) { List<String> roleCodes = roles.stream().map(AuthRole::getCode).collect(Collectors.toList()); if (roleCodes.contains(TEST_ROLE_CODE_01)) { return new ViewAction().setModel(DemoItemCategory.MODEL_MODEL).setName("DemoMenus_ItemPMenu_DemoItemAndCateMenu_DemoItemCategoryMenu").queryOne(); } else if (roleCodes.contains(TEST_ROLE_CODE_02)) { return new ViewAction().setModel(DemoItemLabel.MODEL_MODEL).setName("DemoMenus_ItemPMenu_DemoItemAndCateMenu_DemoItemLabelMenu").queryOne(); } } } catch (PamirsException exception) { if (PamirsSession.getUserId() == null) { throw PamirsException.construct(BaseExpEnumerate.BASE_USER_NOT_LOGIN_ERROR, exception.getCause()).errThrow(); } else { throw exception; } } return null; } }

  如何在代码中使用自增ID和获取序列

  在使用继承IDModel或CodeModel时，id和code是系统默认自动生成, 默认值规则：ID–>分布式ID； CODE–>根据定义的SequenceConfig规则自动生成。 在特定情况下需要落库前先生成ID或者Code，这些场景下可参照如下代码示例 一、使用自增ID 单个字段设置方式 // 主键字段，可以使用mysql的自增能力 @Field.Integer @Field.PrimaryKey(keyGenerator = KeyGeneratorEnum.AUTO_INCREMENT) @Field.Advanced(batchStrategy = FieldStrategyEnum.NEVER) @Field(displayName = "id", summary = "Id字段，⾃增") private Long id; @Field.Integer @Field(displayName = "自增版本") @Field.Sequence(sequence = "SEQ", initial = 1) private Long version; 全局设置方式 该方式会作用到每一个存储模型的id字段，在application.yml配置文件中修改id的生成规则，查找配置项关键字key-generator，默认为DISTRIBUTION(分布式id)，可修改为 AUTO_INCREMENT(自增id) 二、手动方式获取序列 获取方式示例1 /** * 在特定场景下需要手动生成Id或者code时，可参照这个示例 */ public void manualSetIdCode(){ DemoItem demoItem = new DemoItem(); //手动生成ID和code Object idObj = Spider.getDefaultExtension(IdGenerator.class).generate(PamirsTableInfo.fetchKeyGenerator(DemoItem.MODEL_MODEL)); demoItem.setId(TypeUtils.createLong(idObj)); Object codeObj = CommonApiFactory.getSequenceGenerator().generate("SEQ",DemoItem.MODEL_MODEL); String code = TypeUtils.stringValueOf(codeObj); demoItem.setCode(code); //…… } 获取方式示例2 1、在系统启动的时候初始化SequenceConfig package pro.shushi.pamirs.demo.core.init; import org.springframework.stereotype.Component; import pro.shushi.pamirs.boot.common.api.command.AppLifecycleCommand; import pro.shushi.pamirs.boot.common.extend.MetaDataEditor; import pro.shushi.pamirs.core.common.InitializationUtil; import pro.shushi.pamirs.demo.api.DemoModule; import pro.shushi.pamirs.demo.core.constant.SeqConstants; import pro.shushi.pamirs.meta.annotation.fun.extern.Slf4j; import pro.shushi.pamirs.meta.api.dto.meta.Meta; import pro.shushi.pamirs.meta.enmu.SequenceEnum; import java.util.Map; /** * DemoMetadataEditor */ @Slf4j @Component public class DemoMetadataEditor implements MetaDataEditor { @Override public void edit(AppLifecycleCommand command, Map<String, Meta> metaMap) { InitializationUtil util = InitializationUtil.get(metaMap, DemoModule.MODULE_MODULE, DemoModule.MODULE_NAME); if (util == null) { log.error("获取初始化序列失败"); return; } bizSequence(util); } private void bizSequence(InitializationUtil util) { util.createSequenceConfig("申请单编码生成", SeqConstants.NABEL_SAMPLE_APPLY_SEQ, SequenceEnum.ORDERLY_SEQ, 8) .setStep(1) .setInitial(80000000L) .setIsRandomStep(false); util.createSequenceConfig("订单编码生成", SeqConstants.NABEL_SAMPLE_ORDER_SEQ_YP, SequenceEnum.ORDERLY_SEQ, 8) .setPrefix("YP") .setStep(1) .setInitial(80000000L) .setIsRandomStep(false); } } 2、在代码中使用序列 public static String getSaleOrderCode() { Object sequence = CommonApiFactory.getSequenceGenerator().generate(SequenceEnum.ORDERLY_SEQ.value(), SeqConstants.NABEL_SAMPLE_STRUCTURE_SEQ); return TypeUtils.stringValueOf(sequence); } public static String getApplyOrderCode(String prefix) { Object sequence = CommonApiFactory.getSequenceGenerator().generate(SequenceEnum.ORDERLY_SEQ.value(), SeqConstants.NABEL_SAMPLE_APPLY_SEQ); return…
