刚刚使用了activity做了一个项目，第一次就腆着脸给写出来吧！！！

审批流肯定要创建流程图，再编辑器上装bpm插件

 装完就可以使用了

 要创建在resources/processes/新建个文件夹叫processes 不然会报错：

Caused by: java.io.FileNotFoundException: class path resource [processes/] cannot be resolved to URL because it does not exist 不存在这个文件夹

解决方法2在配置文件中配置:

在application.properties文件加配置

# spring-activiti

# 自动部署验证设置:true-开启（默认）、false-关闭

spring.activiti.check-process-definitions=false

 如上流程图就是这么简单 但是这文件可以用文本方式打开代码如下：

这这里面有牵涉到多个项目管理员审批 一个人通过就是通过了 这属于多实例的一种，当时处理起来我有点不知道怎么处理 所以搜寻了很多的资料 （这可能是我不知道怎么搜索所以花费了不少时间）

最终就用了一句话

<![CDATA[${nrOfCompletedInstances/nrOfInstances > 0}]]>
这里的nrOfCompletedInstances 相当于处理人数nrOfInstances：需要处理的人数  
我的需求是只要有一人处理就行 那就商大于0就OK  要是都需要处理 那就是 商恒等于0  哈哈原来这么简单  
我这个应该只是工作流中的九牛一毛  里面有很多学问。有机会多多和博友交流
嘻嘻
