平台提供了很多的表达式,如果这些表达式不满足场景?那我们应该如何新增表达式去满足项目的需求?目前平台支持的表达式内置函数,参考 1. 扩展表达式的场景 注解@Validation的rule字段支持配置表达式校验如果需要判断入参List类型字段中的某一个参数进行NULL校验,发现平台的内置函数不支持该场景的配置,这里就可以通过平台的机制,对内置函数进行扩展。 常见的一些代码场景,如下: package pro.shushi.pamirs.demo.core.action; ……引用类 @Model.model(PetShopProxy.MODEL_MODEL) @Component public class PetShopProxyAction extends DataStatusBehavior<PetShopProxy> { @Override protected PetShopProxy fetchData(PetShopProxy data) { return data.queryById(); } @Validation(ruleWithTips = { @Validation.Rule(value = "!IS_BLANK(data.code)", error = "编码为必填项"), @Validation.Rule(value = "LEN(data.name) < 128", error = "名称过长,不能超过128位"), }) @Action(displayName = "启用") @Action.Advanced(invisible="!(activeRecord.code !== undefined && !IS_BLANK(activeRecord.code))") public PetShopProxy dataStatusEnable(PetShopProxy data){ data = super.dataStatusEnable(data); data.updateById(); return data; } ……其他代码 } 2. 新建一个自定义表达式的函数 校验入参如果是个集合对象的情况下,单个对象的某个字段如果为空,返回false的函数。 例子:新建一个CustomCollectionFunctions类 package xxx.xxx.xxx; import org.apache.commons.collections4.CollectionUtils; import org.springframework.stereotype.Component; import pro.shushi.pamirs.meta.annotation.Fun; import pro.shushi.pamirs.meta.annotation.Function; import pro.shushi.pamirs.meta.common.constants.NamespaceConstants; import pro.shushi.pamirs.meta.util.FieldUtils; import java.util.List; import static pro.shushi.pamirs.meta.enmu.FunctionCategoryEnum.COLLECTION; import static pro.shushi.pamirs.meta.enmu.FunctionLanguageEnum.JAVA; import static pro.shushi.pamirs.meta.enmu.FunctionOpenEnum.LOCAL; import static pro.shushi.pamirs.meta.enmu.FunctionSceneEnum.EXPRESSION; /** * 自定义内置函数 */ @Fun(NamespaceConstants.expression) @Component public class CustomCollectionFunctions { /** * LIST_FIELD_NULL 就是我们自定义的表达式,不能与已经存在的表达式重复!!! * * @param list * @param field * @return */ @Function.Advanced( displayName = "校验集成的参数是否为null", language = JAVA, builtin = true, category = COLLECTION ) @Function.fun("LIST_FIELD_NULL") @Function(name = "LIST_FIELD_NULL", scene = {EXPRESSION}, openLevel = LOCAL, summary = "函数示例: LIST_FIELD_NULL(list,field),函数说明: 传入一个对象集合,校验集合的字段是否为空" ) public Boolean listFieldNull(List list, String field) { if (null == list) { return false; } if (CollectionUtils.isEmpty(list)) { return false; } for (Object data : list) { Object value =…

框架之信息概述 后端除了可以返回错误信息以外,还可以返回调试、告警、成功、信息等级别的信息给前端。但是默认情况下前端只提示错误信息,可以通过前端的统一配置放开提示级别,有点类似后端的日志级别。 框架之MessageHub 在oinone平台中,我们怎么做到友好的错误提示呢?接下来介绍我们的MessageHub,它为自定义错误提示提供无限的可能。 何时使用 错误提示是用户体验中特别重要的组成部分,大部分的错误体现在整页级别,字段级别,按钮级别。友好的错误提示应该是怎么样的呢?我们假设他是这样的 与用户操作精密契合 当字段输入异常时,错误展示在错误框底部 按钮触发服务时异常,错误展示在按钮底部 区分不同的类型 错误 成功 警告 提示 调试 简洁易懂的错误信息 不同信息类型的举例 package pro.shushi.pamirs.demo.core.action; import org.springframework.stereotype.Component; import pro.shushi.pamirs.demo.api.model.PetCatItem; import pro.shushi.pamirs.demo.api.model.PetType; import pro.shushi.pamirs.meta.annotation.Action; import pro.shushi.pamirs.meta.annotation.Model; import pro.shushi.pamirs.meta.api.dto.common.Message; import pro.shushi.pamirs.meta.api.session.PamirsSession; import pro.shushi.pamirs.meta.enmu.ActionContextTypeEnum; import pro.shushi.pamirs.meta.enmu.InformationLevelEnum; import pro.shushi.pamirs.meta.enmu.ViewTypeEnum; @Model.model(PetType.MODEL_MODEL) @Component public class PetTypeAction { @Action(displayName = "消息",bindingType = ViewTypeEnum.TABLE,contextType = ActionContextTypeEnum.CONTEXT_FREE) public PetType message(PetType data){ PamirsSession.getMessageHub().info("info1"); PamirsSession.getMessageHub().info("info2"); PamirsSession.getMessageHub().error("error1"); PamirsSession.getMessageHub().error("error2"); PamirsSession.getMessageHub().msg(new Message().msg("success1").setLevel(InformationLevelEnum.SUCCESS)); PamirsSession.getMessageHub().msg(new Message().msg("success2").setLevel(InformationLevelEnum.SUCCESS)); PamirsSession.getMessageHub().msg(new Message().msg("debug1").setLevel(InformationLevelEnum.DEBUG)); PamirsSession.getMessageHub().msg(new Message().msg("debug2").setLevel(InformationLevelEnum.DEBUG)); PamirsSession.getMessageHub().msg(new Message().msg("warn1").setLevel(InformationLevelEnum.WARN)); PamirsSession.getMessageHub().msg(new Message().msg("warn2").setLevel(InformationLevelEnum.WARN)); return data; } } 查询运行返回和效果 1)系统提示的返回结果 2)系统提示示例效果
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"); }…
