环境运行时Jar版本控制
为了避免基于低代码定义产生的元数据错乱。因此产生了运行时Jar版本检查功能。
如果当前运行时依赖的Ja版本低于已安装版本，启动时会有如下类似信息提示：
依赖Jar版本-PgoBack=true 强制覆盖安装当前运行时版本
java -jar 方式
java -jar xxx.jar -PgoBack=true [其他参数]mvn spring-boot run 方式

异步任务总体介绍 函数的触发和定时在很多场景中会用到，也是一个oinone的基础能力。比如我们的流程产品中在定义流程触发时就会让用户选择模型触发还是时间触发，就是用到了函数的触发与定时能力。 触发任务TriggerTaskAction 触发任务的创建，使用sql-record模块监听mysql的binlog事件，通过rocketmq发送变更数据消息，收到MQ消息后，创建TriggerAutoTask。 触发任务的执行，使用TBSchedule拉取触发任务后，执行相应函数。 项目中引入依赖 1、项目的API工程引入依赖pamirs-core-trigger模块 <dependency> <groupId>pro.shushi.pamirs.core</groupId> <artifactId>pamirs-trigger-api</artifactId> </dependency> 2、DemoModule在模块依赖定义中增加@Module(dependencies={TriggerModule.MODULE_MODULE}) @Component @Module( name = DemoModule.MODULE_NAME, displayName = "oinoneDemo工程", version = "1.0.0", dependencies = {ModuleConstants.MODULE_BASE, CommonModule.MODULE_MODULE, UserModule.MODULE_MODULE, TriggerModule.MODULE_MODULE} ) @Module.module(DemoModule.MODULE_MODULE) @Module.Advanced(selfBuilt = true, application = true) @UxHomepage(PetShopProxy.MODEL_MODEL) public class DemoModule implements PamirsModule { ……其他代码 } 3、项目的boot工程引入依赖 <dependency> <groupId>pro.shushi.pamirs.core</groupId> <artifactId>pamirs-trigger-core</artifactId> </dependency> <dependency> <groupId>pro.shushi.pamirs.core</groupId> <artifactId>pamirs-trigger-bridge-tbschedule</artifactId> </dependency> <dependency> <groupId>pro.shushi.pamirs.core</groupId> <artifactId>pamirs-sql-record-core</artifactId> </dependency> yml文件修改（applcation-xxx.yml） a. 修改pamris.event.enabled和pamris.event.schedule.enabled为trueb. pamirs_boot_modules增加启动模块:trigger、sql_record pamirs: record: sql: #改成自己路径 store: /opt/pamirs/logs … event: enabled: true schedule: enabled: true rocket-mq: namesrv-addr: 127.0.0.1:9876 boot: init: true sync: true modules: – base -…… – trigger – sql_record -…… 新建触发任务 新建PetTalentTrigger类，当PetTalent模型的数据记录被新建时触发系统做一些事情 package pro.shushi.pamirs.demo.core.trigger; import pro.shushi.pamirs.demo.api.model.PetTalent; import pro.shushi.pamirs.meta.annotation.Fun; import pro.shushi.pamirs.meta.annotation.Function; import pro.shushi.pamirs.meta.annotation.fun.extern.Slf4j; import pro.shushi.pamirs.trigger.annotation.Trigger; import pro.shushi.pamirs.trigger.enmu.TriggerConditionEnum; @Fun(PetTalent.MODEL_MODEL) @Slf4j public class PetTalentTrigger { @Function @Trigger(displayName = “PetTalent创建时触发”,name = “PetTalent#Trigger#onCreate”,condition = TriggerConditionEnum.ON_CREATE) public PetTalent onCreate(PetTalent data){ log.info(data.getName() + “，被创建”); //可以增加逻辑 return data; } } 定时任务 定时任务是一种非常常见的模式，这里就不介绍概念了，直接进入示例环节 新建PetTalentAutoTask实现ScheduleAction getInterfaceName()需要跟taskAction.setExecuteNamespace定义保持一致，都是函数的命名空间 taskAction.setExecuteFun("execute");跟执行函数名“execute”一致 TaskType需配置为CYCLE_SCHEDULE_NO_TRANSACTION_TASK，把定时任务的schedule线程分开，要不然有一个时间长的任务会导致普通异步或触发任务全部延时。 package pro.shushi.pamirs.demo.core.task; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.stereotype.Component; import pro.shushi.pamirs.core.common.enmu.TimeUnitEnum; import pro.shushi.pamirs.demo.api.model.PetTalent; import pro.shushi.pamirs.meta.annotation.Fun; import pro.shushi.pamirs.meta.annotation.Function; import pro.shushi.pamirs.meta.annotation.fun.extern.Slf4j; import pro.shushi.pamirs.meta.domain.fun.FunctionDefinition; import pro.shushi.pamirs.middleware.schedule.api.ScheduleAction; import pro.shushi.pamirs.middleware.schedule.common.Result; import pro.shushi.pamirs.middleware.schedule.domain.ScheduleItem; import pro.shushi.pamirs.middleware.schedule.eunmeration.TaskType; import pro.shushi.pamirs.trigger.enmu.TriggerTimeAnchorEnum; import pro.shushi.pamirs.trigger.model.ScheduleTaskAction; import pro.shushi.pamirs.trigger.service.ScheduleTaskActionService; @Slf4j @Component @Fun(PetTalent.MODEL_MODEL) public class PetTalentAutoTask implements…
在 Oineone 平台上，自定义视图允许用户替换默认提供的页面布局，以使用自定义页面。本文将指导您如何利用 Oineone 提供的 API 来实现这一点。 默认视图介绍 Oineone 平台提供了多种默认视图，包括： 表单视图 表格视图 表格视图 (左树右表) 详情视图 画廊视图 树视图 每种视图都有其标准的 layout。自定义视图实际上是替换这些默认 layout 的过程。 默认的表单视图 layout <view type="FORM"> <element widget="actionBar" slot="actionBar" slotSupport="action"> <xslot name="actions" slotSupport="action" /> </element> <element widget="form" slot="form"> <xslot name="fields" slotSupport="pack,field" /> </element> </view> 内嵌的的表单视图 layout <view type="FORM"> <element widget="form" slot="form"> <xslot name="fields" slotSupport="pack,field" /> </element> </view> 默认的表格 <view type="TABLE"> <pack widget="group"> <view type="SEARCH"> <element widget="search" slot="search" slotSupport="field" /> </view> </pack> <pack widget="group" slot="tableGroup"> <element widget="actionBar" slot="actionBar" slotSupport="action"> <xslot name="actions" slotSupport="action" /> </element> <element widget="table" slot="table" slotSupport="field"> <element widget="expandColumn" slot="expandRow" /> <xslot name="fields" slotSupport="field" /> <element widget="rowActions" slot="rowActions" slotSupport="action" /> </element> </pack> </view> 内嵌的的表格 <view type="TABLE"> <view type="SEARCH"> <element widget="search" slot="search" slotSupport="field" /> </view> <element widget="actionBar" slot="actionBar" slotSupport="action"> <xslot name="actions" slotSupport="action" /> </element> <element widget="table" slot="table"> <element widget="expandColumn" slot="expandRow" /> <xslot name="fields" slotSupport="field" /> <element widget="rowActions" slot="rowActions" /> </element> </view> 左树右表 <view type="table"> <pack title="" widget="group"> <view type="search"> <element slot="search" widget="search"/> </view> </pack> <pack title="" widget="group"> <pack widget="row" wrap="false"> <pack widget="col" width="257"> <pack title="" widget="group"> <pack widget="col"> <element slot="tree" widget="tree"/> </pack> </pack> </pack> <pack mode="full" widget="col"> <pack widget="row"> <element justify="START" slot="actionBar"…
概述 在使用Oinone低代码平台进行项目开发的过程中，会存在把平台默认提供的菜单加到自己的项目中。这篇文章介绍实现方式，以角色管理为例。 1. 低代码情况 即项目是通过后端代码初始化菜单的方式。 通常在 XXXMenu.java类通过@UxMenu注解的方式，代码片段如下： 此种情况与添加项目本地的菜单无区别，具体代码： @UxMenu(value = "账号管理", icon = "icon-yonghuguanli") class AccountManage { @UxMenu("用户管理") @UxRoute(value = CustomerCompanyUserProxy.MODEL_MODEL, title = "用户管理") class CompanyUserManage { } @UxMenu("角色管理") @UxRoute(value = AuthRole.MODEL_MODEL, module = AdminModule.MODULE_MODULE, title = "角色管理") class RoleManage { } @UxMenu("操作日志") @UxRoute(value = OperationLog.MODEL_MODEL, module = AdminModule.MODULE_MODULE/***菜单所挂载的模块**/) class OperateLog { } } 2. 无代码情况 在界面设计器中，新建菜单–>选择绑定已有页面，进行发布即可。
