这个是报的错误，程序是放在linux主机上的服务器是resin，请高手指点。报错是找不到i那个文件，可是那个文件确实存在，。。。。
这个是在linux服务器上

参考技术A 程序的路径、、
你注意相对路径的使用。。
路径前面加‘/’表示绝对路径
一般相对路径的用法是 ../XX 参考技术B Caused by: java.io.FileNotFoundException: /usr/local/resin/webapps/adtoolsweb/META-INF/MANIFEST.MF
清单文件没有？检查下资源路径吧。

Activiti 初级入门项目

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

技术图片

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
