2.1 自动触发方式
2.2 触发方式

1.使用工作流需要依赖的包和设置

1.1 工作流需要依赖的模块

需在pom.xml中增加workflow、sql-record和trigger相关模块的依赖

  • workflow:工作流运行核心模块
  • sql-record:监听流程发布以后对应模型的增删改监听
  • trigger:异步任务调度模块
<dependency>
    <groupId>pro.shushi.pamirs.workflow</groupId>
    <artifactId>pamirs-workflow-api</artifactId>
</dependency>
<dependency>
    <groupId>pro.shushi.pamirs.workflow</groupId>
    <artifactId>pamirs-workflow-core</artifactId>
</dependency>

<dependency>
    <groupId>pro.shushi.pamirs.core</groupId>
    <artifactId>pamirs-sql-record-core</artifactId>
</dependency>

<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>

在application.yml中增加对应模块的依赖以及sql-record路径以及其他相关设置

pamirs:
...

  record:
    sql:
      #改成自己路径
      store: /opt/pamirs/logs
...

  boot:
    init: true
    sync: true
    modules:
...
      - sql_record
      - trigger
      - workflow
...

  sharding:
    define:
      data-sources:
        ds:
          pamirs
      models:
        "[trigger.PamirsSchedule]":
          tables: 0..13

  event:
    enabled: true
    schedule:
      enabled: true
      # ownSign区分不同应用
      ownSign: demo
    rocket-mq:
      # enabled 为 false情况不用配置
      namesrv-addr: 192.168.6.2:19876
    trigger:
      auto-trigger: true

2.触发方式

2.1自动触发方式

在流程设计器中设置触发方式,如果设置了代码触发方式则不会自动触发

2.2代码调用方式触发

2.2.1.再流程设计器中触发设置中,设置为是否人工触发设置为是

数式Oinone低代码-代码方式调用触发工作流

2.2.2.查询数据库获取该流程的编码

数式Oinone低代码-代码方式调用触发工作流

2.2.3.在代码中调用

/**
     * 触发⼯作流实例
     */
    private Boolean startWorkflow(WorkflowD workflowD, IdModel modelData) {
        WorkflowDefinition workflowDefinition = new WorkflowDefinition().queryOneByWrapper(
                Pops.<WorkflowDefinition>lambdaQuery()
                        .from(WorkflowDefinition.MODEL_MODEL)
                        .eq(WorkflowDefinition::getWorkflowCode, workflowD.getCode())
                        .eq(WorkflowDefinition::getActive, 1)
        );
        if (null == workflowDefinition) {
            // 流程没有运⾏实例
            return Boolean.FALSE;
        }
        String model = Models.api().getModel(modelData);

        //⼯作流上下⽂
        WorkflowDataContext wdc = new WorkflowDataContext();
        wdc.setDataType(WorkflowVariationTypeEnum.ADD);
        wdc.setModel(model);
        wdc.setWorkflowDefinitionDefinition(workflowDefinition.parseContent());
        wdc.setWorkflowDefinition(workflowDefinition);
        wdc.setWorkflowDefinitionId(workflowDefinition.getId());
        IdModel copyData = KryoUtils.get().copy(modelData);
        // ⼿动触发创建的动作流,将操作⼈设置为当前⽤户,作为流程的发起⼈
        copyData.setCreateUid(PamirsSession.getUserId());
        copyData.setWriteUid(PamirsSession.getUserId());
        String jsonData = JsonUtils.toJSONString(copyData.get_d());
        //触发⼯作流 新增时触发-onCreateManual 更新时触发-onUpdateManual
        Fun.run(WorkflowModelTriggerFunction.FUN_NAMESPACE, "onCreateManual", wdc, msgId, jsonData);
        return Boolean.TRUE;
    }

  • Excel导入扩展点-整体导入(批量导入)

    1、【导入】在有些场景,需要获取Excel导入的整体数据,进行批量的操作或者校验 可以通过实现导入扩展点的方式实现,入参data是导入Excel的数据列表;业务可以根据实际情况进行数据校验 1)Excel模板定义,需要设置setEachImport(false) 2)导入扩展点API定义 pro.shushi.pamirs.file.api.extpoint.ExcelImportDataExtPoint#importData 3)示例代码参考: pro.shushi.pamirs.translate.extpoint.ResourceTranslationImportExtPoint#importData @Slf4j @Component @Ext(ExcelImportTask.class) public class ResourceTranslationImportExtPoint extends AbstractExcelImportDataExtPointImpl<List<ResourceTranslationItem>> { @Override //TODO 表达式,可以自定义,比如可以支持1个模型的多个【导入名称】的不同模板 @ExtPoint.Implement(expression = "importContext.definitionContext.model==\"" + ResourceTranslation.MODEL_MODEL + "\"") public Boolean importData(ExcelImportContext importContext, List<ResourceTranslationItem> dataList) { //TODO dataList就是excel导入那个sheet的所有内容 return true; } } 2、【导入】逐行导入的时候做事务控制 在模板中定义中增加事务的定义,并设置异常后回滚。参加示例代码: excel模板定义 @Component public class DemoItemImportTemplate implements ExcelTemplateInit { public static final String TEMPLATE_NAME = "商品导入模板"; @Override public List<ExcelWorkbookDefinition> generator() { //定义事务(导入处理中,只操作单个表的不需要事务定义。) //是否定义事务根据实际业务逻辑确定。比如:有些场景在导入前需要删除数据后在进行导入就需要定义事务 InitializationUtil.addTxConfig(DemoItem.MODEL_MODEL, ExcelDefinitionContext.EXCEL_TX_CONFIG_PREFIX + TEMPLATE_NAME); return Collections.singletonList( ExcelHelper.fixedHeader(DemoItem.MODEL_MODEL, TEMPLATE_NAME) .setType(ExcelTemplateTypeEnum.IMPORT) .createSheet("商品导入-sheet1") .createBlock(DemoItem.MODEL_MODEL) .addUnique(DemoItem.MODEL_MODEL,"name") .addColumn("name","名称") .addColumn("description","描述") .addColumn("itemPrice","单价") .addColumn("inventoryQuantity","库存") .build().setEachImport(true) //TODO 设置异常后回滚的标识,这个地方会回滚事务 .setHasErrorRollback(true) .setExcelImportMode(ExcelImportModeEnum.SINGLE_MODEL) ); } } 导入逻辑处理 @Slf4j @Component @Ext(ExcelImportTask.class) public class DemoItemImportExtPoint extends AbstractExcelImportDataExtPointImpl<DemoItem> implements ExcelImportDataExtPoint<DemoItem> { @Autowired private DemoItemService demoItemService; @Override @ExtPoint.Implement(expression = "importContext.definitionContext.model == \"" + DemoItem.MODEL_MODEL + "\"") public Boolean importData(ExcelImportContext importContext, DemoItem data) { ExcelImportTask importTask = importContext.getImportTask(); try { DemoItemImportTask hrExcelImportTask = new DemoItemImportTask().queryById(importTask.getId()); String publishUserName = Optional.ofNullable(hrExcelImportTask).map(DemoItemImportTask::getPublishUserName).orElse(null); data.setPublishUserName(publishUserName); demoItemService.create(data); } catch(PamirsException e) { log.error("导入异常", e); } catch (Exception e) { log.error("导入异常", e); } return Boolean.TRUE; } }

  • 【工作流】流程扩展自定义函数示例代码汇总

    目录 1. 流程节点审批人函数2. 审批开始前执行函数3. 填写执行前执行函数4. 待办操作提交后执行函数5. 审批操作数据函数6. 自定义通知人函数 1. 流程节点审批人函数 包含转交、抄送、加签、填写、通知人自定义函数当平台默认提供的审批人选择无法满足个性化的业务需求时,我们可以通过自定义函数处理审批人的生成逻辑 1.1 编写自定义审批人函数 @Function(openLevel = {FunctionOpenEnum.API}) @Function.Advanced(type = FunctionTypeEnum.QUERY, displayName = "报销单-证明人-审批", category = CUSTOM_DESIGNER) public List<NodePerson> bizZmrApprovePerson(List<NodePerson> nodePersonList, NodeModel nodeModel, WorkflowContext workflowContext) { List<NodePerson> newNodePersonList = new ArrayList<>(); String nodeModelId = nodeModel.getId(); Object nodeData = workflowContext.get(nodeModelId); BuissModel inputBuissModel = JsonUtils.parseObject(JsonUtils.toJSONString(nodeData), BUISSMODEL_TR); BuissModel buissModel = new BuissModel().setId(inputBuissModel.getId()).queryById(); buissModel.fieldQuery(BuissModel::getZmEmployee); BxEmployee zmEmployee = buissModel.getZmEmployee(); if (zmEmployee == null) { log.error("报销单ID:{},名称:{}, 获取证明人为空", buissModel.getId(), buissModel.getName()); return newNodePersonList; } NodePersonUser personUser = new NodePersonUser(); List<NodePersonUser> nodePersonUsers = new ArrayList<>(); NodePerson person = new NodePerson(); person.setId(zmEmployee.getBindingUserId() + ""); person.setType(NodePersonTypeEnum.USER); personUser.setUserId(zmEmployee.getBindingUserId()); nodePersonUsers.add(personUser); person.setNodePersonUsers(nodePersonUsers); newNodePersonList.add(person); return newNodePersonList; } 1.2 流程设计器的审批节点设置自定义函数 2.审批开始前执行函数 使用场景:在流程执行到审批或填写节点任务初始化后,任务尚未开始,需要在初始化任务做一些自定义逻辑处理时,使用该扩展执行时间:执行节点是在审批或填写待办任务初始化之后,审批或填写结果执行之前,执行该扩展 /** * 审批节点初始化完成,执行前置函数 * @param approvalNode * @param context * @param taskInstance */ @Function(name = "approvalCustomStartFun",openLevel = FunctionOpenEnum.API) @Function.Advanced(type= FunctionTypeEnum.QUERY,displayName = "审批执行前置处理",category = FunctionCategoryEnum.CUSTOM_DESIGNER ) public void approvalCustomStartFun(ApprovalNode approvalNode, WorkflowContext context, WorkflowTaskInstance taskInstance) { // TODO: 2024/2/23 可以根据结果自己处理业务逻辑 } 3.填写执行前执行函数 /** * 填写执行前置处理 */ @Function(name = "writeCustomStartFun", openLevel = FunctionOpenEnum.API) @Function.Advanced(type = FunctionTypeEnum.QUERY, displayName = "填写执行前置处理", category = FunctionCategoryEnum.CUSTOM_DESIGNER) public void writeCustomStartFun(WorkflowTaskInstance taskInstance, WriteNode writeNode, WorkflowContext context) { System.out.println("填写执行前置处理"); } 4. 待办操作提交后执行函数 使用场景:在审批或填写的待办任务在操作任务时,需要额外执行一些逻辑,比如当前人提交操作以后需要更新更当前人操作相关的数据库记录,执行时间:执行节点是在保存待办任务之后,异步执行审批或填写结果之前,执行该扩展 /** * 转交操作后置函数,再流程设计器中审批和填写节点中…
