扩展操作日志字段，实现操作日志界面显示自定义字段
注：该功能在pamirs-core 4.3.27 / 4.7.8.12以上版本可用 在模块依赖里新增DataAuditModule.MODULE_MODULE模块依赖。 @Module( name = DemoModule.MODULE_NAME, dependencies = { CommonModule.MODULE_MODULE, DataAuditModule.MODULE_MODULE }, displayName = “****”, version = “1.0.0” ) 继承OperationBody模型，设置需要在操作日志中显示的字段，并重写clone方法，设置自定义字段值。用于在计入日志处传递参数。 public class MyOperationBody extends OperationBody { public MyOperationBody(String operationModel, String operationName) { super(operationModel, operationName); } private String itemNames; public String getItemNames() { return itemNames; } public void setItemNames(String itemNames) { this.itemNames = itemNames; } @Override public OperationBody clone() { //设置自定义字段值 MyOperationBody body = OperationBody.transfer(this, new MyOperationBody(this.getOperationModel(), this.getOperationName())); body.setItemNames(this.getItemNames()); return body; } } 继承OperationLog模型，新增需要在操作日志中显示的字段。用于界面展示该自定义字段。 @Model.model(MyOperationLog.MODEL_MODEL) @Model(displayName = “自定义操作日志”, labelFields = {“itemNames”}) public class MyOperationLog extends OperationLog { public static final String MODEL_MODEL = “operation.MyOperationLog”; @Field(displayName = “新增日志字段”) @Field.String private String itemNames; } 定义一个常量 public interface OperationLogConstants { String MY_SCOPE = “MY_SCOPE”; } 在计入日志处，构造出MyOperationBody对象，向该对象中设置自定义日志字段。构造OperationLogBuilder对象并设置scope的值，用于跳转自定义服务实现。 MyOperationBody body = new MyOperationBody(CustomerCompanyUserProxy.MODEL_MODEL, CustomerCompanyUserProxyDataAudit.UPDATE); body.setItemNames(“新增日志字段”); OperationLogBuilder builder = OperationLogBuilder.newInstance(body); //设置一个scope，用于跳转自定义服务实现.OperationLogConstants.MY_SCOPE是常量，请自行定义 builder.setScope(OperationLogConstants.MY_SCOPE); //记录日志 builder.record(data.queryByPk(), data); 实现OperationLogService接口，加上@SPI.Service()注解，并设置常量，一般为类名。定义scope（注意：保持和计入日志处传入的scope值一致），用于计入日志处找到该自定义服务实现。根据逻辑重写父类中方法，便可以扩展操作日志，实现自定义记录了。 @Slf4j @Service @SPI.Service(“myOperationLogServiceImpl”) public class MyOperationLogServiceImpl< T extends D > extends OperationLogServiceImpl< T > implements OperationLogService< T >{ //定义scope，用于计入日志处找到该自定义服务实现 private static final String[] MY_SCOPE = new String[]{OperationLogConstants.MY_SCOPE}; @Override public String[] scopes() { return MY_SCOPE; } //此方法用于创建操作日志 @Override protected OperationLog createOperationLog(OperationBody body, OperationLogConfig config) { MyOperationBody body1 = (MyOperationBody)…

后端：如何自定义表达式实现特殊需求？扩展内置函数表达式
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 =…

函数之异步执行
总体介绍 异步任务是非常常见的一种开发模式，它在分布式的开发模式中有很多应用场景如： 高并发场景中，我们一般采用把长流程切短，用异步方式去掉可以异步的非关键功能，缩小主流程响应时间，提升用户体验 异构系统的集成调用，通过异步任务完成解耦与自动重试 分布式系统最终一致性的可选方案 本文将介绍oinone是如何结合Spring+TbSchedule来完成异步任务 构建第一个异步任务 新建PetShopService和PetShopServiceImpl 1、 新建PetShopService定义updatePetShops方法 package pro.shushi.pamirs.demo.api.service; import pro.shushi.pamirs.demo.api.model.PetShop; import pro.shushi.pamirs.meta.annotation.Fun; import pro.shushi.pamirs.meta.annotation.Function; import java.util.List; @Fun(PetShopService.FUN_NAMESPACE) public interface PetShopService { String FUN_NAMESPACE = "demo.PetShop.PetShopService"; @Function void updatePetShops(List<PetShop> petShops); } 2、PetShopServiceImpl实现PetShopService接口并在updatePetShops增加@XAsync注解 package pro.shushi.pamirs.demo.core.service; import org.springframework.stereotype.Component; import pro.shushi.pamirs.demo.api.model.PetShop; import pro.shushi.pamirs.demo.api.service.PetShopService; import pro.shushi.pamirs.meta.annotation.Fun; import pro.shushi.pamirs.meta.annotation.Function; import pro.shushi.pamirs.trigger.annotation.XAsync; import java.util.List; @Fun(PetShopService.FUN_NAMESPACE) @Component public class PetShopServiceImpl implements PetShopService { @Override @Function @XAsync(displayName = "异步批量更新宠物商店",limitRetryNumber = 3,nextRetryTimeValue = 60) public void updatePetShops(List<PetShop> petShops) { new PetShop().updateBatch(petShops); } } a. displayName = "异步批量更新宠物商店"，定义异步任务展示名称b. limitRetryNumber = 3，定义任务失败重试次数，，默认：-1不断重试c. nextRetryTimeValue = 60，定义任务失败重试的时间数，默认：3d. nextRetryTimeUnit，定义任务失败重试的时间单位，默认：TimeUnitEnum.SECONDe. delayTime，定义任务延迟执行的时间数，默认：0f. delayTimeUnit，定义任务延迟执行的时间单位，默认：TimeUnitEnum.SECOND 修改PetShopBatchUpdateAction调用异步任务 引入PetShopService 修改conform方法，调用petShopService.updatePetShops方法 package pro.shushi.pamirs.demo.core.action; @Model.model(PetShopBatchUpdate.MODEL_MODEL) @Component public class PetShopBatchUpdateAction { @Autowired private PetShopService petShopService; @Action(displayName = "确定",bindingType = ViewTypeEnum.FORM,contextType = ActionContextTypeEnum.SINGLE) public PetShopBatchUpdate conform(PetShopBatchUpdate data){ List<PetShop> shops = ArgUtils.convert(PetShopProxy.MODEL_MODEL, PetShop.MODEL_MODEL,proxyList); // 调用异步任务 petShopService.updatePetShops(shops); }); return data; } } 不同应用如何隔离执行单元 在schedule跟模块部署一起的时候，多模块独立boot的情况下，需要做必要的配置。如果schedule独立部署则没有必要，因为全部走远程，不存在类找不到的问题 通过配置pamirs.zookeeper.rootPath，确保两组机器都能覆盖所有任务分片，这样不会漏数据 通过pamirs.event.schedule.ownSign来隔离。确保两组机器只取各自产生的数据，这样不会重复执行数据 pamirs: zookeeper: zkConnectString: 127.0.0.1:2181 zkSessionTimeout: 60000 rootPath: /demo event: enabled: true schedule: enabled: true ownSign: demo rocket-mq: namesrv-addr: 127.0.0.1:9876

函数之触发与定时配置和示例
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…
