Question

我正在使用activiti-5.21.0。我有我创建了myProcess.bpmn，它有用户任务。用户任务有一个表单。当受理人用户提交此表格时，即“kermit”，那么如何读取以java类形式提交的数据？

myProcess.bpmn型号：

  <process id="myProcess" name="My process" isExecutable="true">
    <startEvent id="startevent1" name="Start"></startEvent>
    <userTask id="usertask1" name="User Task" activiti:assignee="kermit">
      <extensionElements>
        <activiti:formProperty id="name" name="Name" type="string" required="true"></activiti:formProperty>
        <activiti:formProperty id="comment" name="comment" type="string"></activiti:formProperty>
        <activiti:executionListener event="start" class="com.demo.ActivitiForm"></activiti:executionListener>
      </extensionElements>
    </userTask>
    <endEvent id="endevent1" name="End"></endEvent>
    <sequenceFlow id="flow1" sourceRef="startevent1" targetRef="usertask1"></sequenceFlow>
    <sequenceFlow id="flow2" sourceRef="usertask1" targetRef="endevent1"></sequenceFlow>
  </process>

Answer 1

如果您想从任何地方访问变量（无论流程如何）。使用流程实例ID，您可以尝试这个 -

Map<String, Object> variables = runtimeService.getVariables(processInstanceId);
String name = (String)variable.get("name");
String comment = (String)variable.get("comment");

Answer 2

更改执行event="end"然后尝试此操作 -

package com.demo;

//all import statement

public class ActivitiForm implements ExecutionListener {

  public void notify(ExecutionListenerExecution execution) throws Exception {
    String name = (String) execution.getVariable("name");
    String comment = (String) execution.getVariable("comment");
    System.out.println(name + " made the following comment: " + comment);           //see this sys.out in your admin log.
  }
}
