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

使用扩展点实现用户中心菜单替换 1. 工程中引起pamirs-user-api <dependency> <groupId>pro.shushi.pamirs.core</groupId> <artifactId>pamirs-user-api</artifactId> </dependency> 2. 实现TopBarUserBlockAction的后置扩展 实现HookAfter后置扩展接口 @Hook(model = {TopBarUserBlock.MODEL_MODEL}, fun = {"construct"})添加Hook注解注明是TopBarUserBlock模型的construct函数的后置扩展。 增加用户中心菜单 @Component @Order(1) @SPI.Service public class MyTopBarActionExt implements TopBarActionExtendApi { public void edit(List<TopBarAction> list) { list.add(new TopBarAction("top_demo", "top.Teacher", "uiView9a0caf1d574a42c9847a057a0c4a4ad1", ActionTypeEnum.VIEW, 1) .setDisplayName("商品管理") .setIcon("oinone-gongzuotai") ); } } 实现效果 替换原有的用户中心菜单 替换原有的菜单跳转 @Component public class DemoTopBarUserBlockDataHookAfter implements HookAfter { @Override @Hook(model = {TopBarUserBlock.MODEL_MODEL}, fun = {"construct"}) public Object run(Function function, Object ret) { if (ret == null) { return null; } TopBarUserBlock result = null; if (ret instanceof Object[]) { Object[] rets = (Object[]) ((Object[]) ret); if (rets.length == 1) { result = (TopBarUserBlock) rets[0]; //例:替换用户中心:修改密码菜单 //使用name和model查询出模型的ViewAction替换修改密码ViewAction ViewAction demoViewAction = PamirsSession.getContext().getExtendCache(ActionCacheApi.class).get(Dog.MODEL_MODEL, "changePassword"); //设置菜单的icon Map<String, Object> attributes = Optional.ofNullable(demoViewAction.getAttributes()).orElse(new HashMap<>()); attributes.put("icon", "oinone-xiugaimima"); demoViewAction.setAttributes(attributes); //UserViewAction第0个是修改密码ViewAction,使用自定义的ViewAction就可以实现替换 result.getUserViewAction().set(0, demoViewAction); } } else { result = (TopBarUserBlock) ret; } return result; } } 使用@UxRouteButton方式新增ViewAction,更多新增Action方式详见:Action的类型 @Model.model(Dog.MODEL_MODEL) @Component @UxRouteButton( action = @UxAction(name = "changePassword", displayName = "修改密码"), value = @UxRoute(model = Dog.MODEL_MODEL, openType = ActionTargetEnum.DIALOG)) public class DogAction { } 替换原有的个人设置头像跳转 修改点击头像绑定的跳转逻辑 @Order(10) @Component @SPI.Service public class DemoTopBarUserBlockDataApi implements TopBarUserBlockDataApi { @Override public TopBarUserBlock extendData(TopBarUserBlock data) { //例如增加一个菜单, PamirsDemo.MODEL_MODEL: 模型。 MenuuiMenu31f22466735a4abe8e0544b428ed88ac:viewAction的name。 Action demoViewAction =…
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 =…
