Flowable 外部表单

内置表单需要在每个节点中去配置，当如果多个节点使用同一套表单属性就要配置多次比较麻烦，修改的时候也要修改多次，外部表单可以定义一次，然后其它节点都去引用同一个表单属性。
外部表单需要定义一个.form后缀的文件。
外部表单不需要在每个节点去指定From属性，而是在每个节点指定Form Key属性即可。

定义.form

FormLeaveProcess.form

{
  "key":"FormLeaveProcess",
  "name": "请假流程外部表单",
  "fields": [
    {
      "id": "startTime",
      "name": "请假开始时间",
      "type": "date",
      "required": true,
      "placeholder": "empty"
    },
    {
      "id": "endTime",
      "name": "请假结束时间",
      "type": "date",
      "required": true,
      "placeholder": "empty"
    },
    {
      "id": "reason",
      "name": "请假原因",
      "type": "string",
      "required": false,
      "placeholder": "empty"
    }
  ]
}

部署流程和部署表单

@Autowired
private RepositoryService repositoryService;

@Autowired
private FormRepositoryService formRepositoryService;

@Test
void deployFormProcess() {
	// 1.部署流程
    Deployment deploy = repositoryService.createDeployment()
            .addClasspathResource("processes/FormLeaveProcess.bpmn20.xml")
            .name("外部表单请假流程")
            .deploy();
    // 2.部署表单
    formRepositoryService.createDeployment()
            .addClasspathResource("processes/FormLeaveProcess.form")
            .name("请假流程外部表单")
            .parentDeploymentId(deploy.getId())
            .deploy();
}

启动流程

@Autowired
private RuntimeService runtimeService;

@Test
void startProcess() {
    String processDefinitionId = "FormLeaveProcess:2:48920686-8145-11ee-b7ee-0a0a3d6982e3";
    runtimeService.startProcessInstanceWithForm(processDefinitionId, "表单请假流程outcome", null, "huihui的请假流程");
}

请添加图片描述

完成表单任务

@Test
void completeFormTask() {
    Map<String, Object> variables = new HashMap<>();
    variables.put("startTime", "20221111");
    variables.put("endTime", "20231110");
    variables.put("reason", "活着不是为了工作，工作是为了活得更有意义");

    String taskId = "0f273f73-8149-11ee-b15c-0a0a3d6982e3";
    String formDefinitionId = "652cb868-8145-11ee-a2f0-0a0a3d6982e3";
    taskService.completeTaskWithForm(taskId, formDefinitionId, "huihui", variables);
}

获取任务对应的表单数据

@Test
void getTaskFormData() {
    FormInfo taskFormModel = taskService.getTaskFormModel("0f273f73-8149-11ee-b15c-0a0a3d6982e3");
    System.out.println(taskFormModel.getId() + "-" + taskFormModel.getName() + "-" + taskFormModel.getKey());
    SimpleFormModel simpleFormModel = (SimpleFormModel)taskFormModel.getFormModel();
    List<FormField> fields = simpleFormModel.getFields();
    for (FormField field : fields) {
        System.out.println(field.getId() + ":" + field.getType() + ":" + field.getName() + ":" + field.getValue());
    }
}
