本文记录了作者在初次接触Activiti时遇到的错误：ActivitiException: Unknown property used in expression。问题源于在流程启动时，未正确预设流程定义中的动态变量。解决方案是确保在启动流程之前，先设置好流程所需的变量值。

刚接触Activiti，采坑记录，根据流程定义ID来启动流程时报错，信息如下：

  • 实体中定义了申请人字段applicantCode

  • 流程中Assignee设置为动态获取申请人code
    流程图

  • 原代码中直接调用runtimeService接口的startProcessInstanceById();方法来启动一个流程，代码如下，并报org.activiti.engine.ActivitiException: Unknown property used in expression: #{throwLeaseApplyEntity.applicantCode}错误信息。

runtimeService.startProcessInstanceById(pdId);// 根据流程定义ID启动流程
  • 搜了很多资料，原因在于流程里定义的变量名，应该在流程启动前进行赋值，代码如下：
Map<String, Object> variables = new HashMap<>();
variables.put("throwLeaseApplyEntity", throwLeaseApplyEntity);

runtimeService.startProcessInstanceById(pdId, variables);// 根据流程定义ID启动流程
throwLeaseApplyManager.create(throwLeaseApplyEntity);// 填写流程申请表

工作流流向有一个以上的流的方向的时候，必须指定流向，默认时用EL表达式表示，比如一个节点既可以流到A5也可以流到A6，当业务需要流向A5 的时候须指定流转条件${A5} 一条流程有多个流转条件的时候，可以写简单的逻辑： ${A30012==true || A40014==true || A50017==true} 当然在逻辑代码里要指定流向的那个节点为true，其他为false，而且...

最近负责整个流程的开发，从数据库设计到前端，整的有点心累，博客也因为时间问题写少了，后续会慢慢补上的。这次也是第一次接触工作流activiti，百度找这个问题都好像没有一个具体的解决方法，问群里也没有多少人写过activiti，也没有人知道怎么解决（可能是问题太低级了别人都不会出现这个错误哈哈哈哈）所以独自解决了还是很激动兴奋的 问题： 解决过程： 一： 首先我检查了一下我自己画的流程图bpmn文件，发现有个参数没有写 这个参数为什么没有写呢？其实在我印象里是写了的，但是eclipse它不会自动保存，.

从activiti论坛的相关讨论中可以得知，activiti报这个异常的原因多是因为XXX类型可能做为Variable设给了工作流，而这个XXX类型并没有序列化！知道原因后，解决方法就很简单了，只需要将XXX类以及其依赖的其他类实现java.io.Serializable接口就好

下一个流程线是一个表达式类型，而我修改上一个流程时，把表达式都删除了，所以这个结点没有获取到表达式的值，导致流程报错。本身这个结点没有问题，问题出现在下一个结点上。第一，补充表达式，让上图中的表达式不报错。如何解决这个问题呢？
Flowable中加签（委托）后，驳回时报错Unknown property used in expression: ${XXX}

判断，加签委托，使用的是创建新的子任务，向流程变量表中act_ru_variable添加的变量时使用的是本地变量，驳回节点父流程节点时，获取不到执行人变量，报异常。在开发过程中，遇到了，加签后，加签人进行驳回时，出现异常Unknown property used in expression: ${XXX}。本地流程变量：这个只针对流程中某一个具体的 Task（任务）有效，这个任务执行完毕后，这个流程变量就失效了。全局流程变量：在整个流程执行期间，这个流程变量都是有效的。
