activiti6.0学习笔记（五）：核心api之FormSer

一、前言

        本章继续学习activiti6.0的核心api之FormService

二、FormService

      1、复制 testProcess.bpmn20.xml 流程定义文件，并将其改名为 testProcess-form.bpmn20.xml

      <process id="myProcess" isClosed="false" isExecutable="true" name="测试流程" processType="None">

  <startEvent id="startevent1" name="start" activiti:formKey="/rest/process/form/start">

      <activiti:formProperty id="message" name="信息" type="string" required="true"/>

  <endEvent id="endevent1" name="End"/>

  <userTask activiti:assignee="张三" activiti:exclusive="true" id="test" name="用户"

            activiti:formKey="/rest/process/form/userTask">

      <activiti:formProperty id="yesORno" name="审批" required="true" type="string"/>

  <sequenceFlow id="flow1" sourceRef="startevent1" targetRef="test"/>

  <sequenceFlow id="flow2" sourceRef="test" targetRef="endevent1"/>

</process>

2、测试代码如下

/**

*

*  测试FormService

*  FormService的作用：

*  1、解析流程定义中表单项的配置

*  2、提交表单的方式驱动用户节点流转

*  3、获取自动以外部表单key

        String startFormKey = formService.getStartFormKey(processDefinition.getId());

        LOGGER.info("startFormKey = {}",startFormKey );

        //获取开始表单中的数据 对应的是startEvent标签下的扩展属性标签extensionElements下的activiti:formProperty标签的属性

        //每一个formProperty对应下面的一个FormProperty

        startFormProperties.forEach(formProperty ->

LOGGER.info("startFormProperty = {}", ToStringBuilder.reflectionToString(formProperty,ToStringStyle.JSON_STYLE)));

        //下面的方法需要获取taskId，taskId需要流程启动以后才能获取，而不是流程文件中的userTask的id,所以下面的获取方式是错误的

        //TaskFormData taskFormData = formService.getTaskFormData("test");//错误，会报错

        //启动流程并获取taskId

        //启动方式一

//        ProcessInstance processInstance = rule.getRuntimeService().startProcessInstanceByKey("myProcess");

        //启动方式二

        Map properties = Maps.newHashMap();

        properties.put("message","my test message" );

        ProcessInstance processInstance = formService.submitStartFormData(processDefinition.getId(), properties);

        Task task =rule.getTaskService().createTaskQuery().processInstanceId(processInstance.getId()).singleResult();

        TaskFormData taskFormData = formService.getTaskFormData(task.getId());

        List taskFormProperties = taskFormData.getFormProperties();

        taskFormProperties.forEach(taskFormProperty->

LOGGER.info("taskFormProperty = {}", ToStringBuilder.reflectionToString(taskFormProperty,ToStringStyle.JSON_STYLE)));

        Task task1 =rule.getTaskService().createTaskQuery().taskId(task.getId()).singleResult();

        LOGGER.info("task1 = {}",task1 );

    }
