javax.el.PropertyNotFoundException: Cannot resolve identifier ‘approved‘-优快云博客

activiti中流程节点报错javax.el.PropertyNotFoundException: Cannot resolve identifier 'approved'

无法解析标识符 'approved'，即 表达式中引用了变量 approved，但引擎在当前上下文中找不到这个变量。

如果配置了条件表达式

<sequenceFlow ...>
  <conditionExpression xsi:type="tFormalExpression">${approved == true}</conditionExpression>
</sequenceFlow>

则必须将表达式的变量加到以下标签

<userTask id="managerApprove" name="经理审批" activiti:assignee="经理" >
        <extensionElements>
            <activiti:formProperty id="approved" name="审批标志" type="string" required="true"/>
        </extensionElements>
        </userTask>

任务完成时approved参数必须要传

 public void completeTask(String taskId, Map<String, Object> variables) {
        ProcessEngine processEngine = ProcessEngines.getDefaultProcessEngine();
        TaskService taskService= processEngine.getTaskService();
        variables.put("approved",false);
        taskService.complete(taskId, variables);
    }
