• Script Format：脚本类型，groovy
• Script：脚本代码

<process id="ScriptTaskProcess" isClosed="false" isExecutable="true" processType="None">
  <startEvent id="_2" name="StartEvent"/>
  <scriptTask activiti:exclusive="true" id="scriptTask" name="ScriptTask" scriptFormat="groovy">
    <script>
      <![CDATA[
        sum = 0     
        for (i in inputArray)        
          sum += i     
             
        execution.setVariable("result", sum);
      ]]>
    </script>
  </scriptTask>
  <endEvent id="_4" name="EndEvent"/>
  <sequenceFlow id="_5" sourceRef="_2" targetRef="scriptTask"/>
  <sequenceFlow id="_6" sourceRef="scriptTask" targetRef="_4"/>

@Test
void testStartAndComplete() 
	Map<String, Object> map = new HashMap<>();
	map.put("inputArray", Arrays.asList(1, 2));
	runtimeService.startProcessInstanceByKey("ScriptTaskProcess", map);

脚本任务是自动执行的，不需要调用 taskService.complete();
