项目中工作流引入和流程触发

2. 触发方式
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导入导出模板翻译

    导出翻译项 与翻译的导出全部翻译项类似,只是该操作目前没有加入到页面交互中,需要通过工具发起后端服务请求,拿到导入导出翻译Excel模版,添加模版翻译项。(查看路径:文件–导出任务) mutation { excelExportTaskMutation { createExportTask( data: { workbookDefinition: { model: "file.ExcelWorkbookDefinition" name: "excelLocationTemplate" } } ) { name } } } variables: { "path": "/file", "lang": "en-US" } 参数说明:(不在以下说明范围内的参数无需修改) variables.lang参数:用于指定翻译项的目标语言编码,与【资源】-【语言】中的编码一致。 导入翻译项 mutation { excelImportTaskMutation { createImportTask( data: { workbookDefinition: { model: "file.ExcelWorkbookDefinition" name: "excelLocationTemplate" } file: { url: "翻译项URL链接" } } ) { name } } } variables: { "path": "/file" } 参数说明: 将翻译项URL链接改为实际可访问的文件链接即可,可通过页面中任意文件上传的组件获取。
