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 at org.springframework.core.io.ClassPathResource.getURL(ClassPathResource.java:195) at org.springframework.core.io.support.PathMatchingResourcePatternResolver.findPathMatchingResources(PathMatchingResourcePatternResolver.java:495) at org.springframework.core.io.support.PathMatchingResourcePatternResolver.getResources(PathMatchingResourcePatternResolver.java:296) at org.springframework.context.support.AbstractApplicationContext.getResources(AbstractApplicationContext.java:1305) at org.springframework.context.support.GenericApplicationContext.getResources(GenericApplicationContext.java:238) at org.activiti.spring.boot.AbstractProcessEngineConfiguration.discoverProcessDefinitionResources(AbstractProcessEngineConfiguration.java:80) at org.activiti.spring.boot.AbstractProcessEngineAutoConfiguration.baseSpringProcessEngineConfiguration(AbstractProcessEngineAutoConfiguration.java:75) at org.activiti.spring.boot.DataSourceProcessEngineAutoConfiguration$DataSourceProcessEngineConfiguration.springProcessEngineConfiguration(DataSourceProcessEngineAutoConfiguration.java:57) at org.activiti.spring.boot.DataSourceProcessEngineAutoConfiguration$DataSourceProcessEngineConfiguration$$EnhancerBySpringCGLIB$$baa326a5.CGLIB$springProcessEngineConfiguration$1(<generated>) at org.activiti.spring.boot.DataSourceProcessEngineAutoConfiguration$DataSourceProcessEngineConfiguration$$EnhancerBySpringCGLIB$$baa326a5$$FastClassBySpringCGLIB$$cc2270af.invoke(<generated>) at org.springframework.cglib.proxy.MethodProxy.invokeSuper(MethodProxy.java:228) at org.springframework.context.annotation.ConfigurationClassEnhancer$BeanMethodInterceptor.intercept(ConfigurationClassEnhancer.java:361) at org.activiti.spring.boot.DataSourceProcessEngineAutoConfiguration$DataSourceProcessEngineConfiguration$$EnhancerBySpringCGLIB$$baa326a5.springProcessEngineConfiguration(<generated>) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:62) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) at java.lang.reflect.Method.invoke(Method.java:498) at org.springframework.beans.factory.support.SimpleInstantiationStrategy.instantiate(SimpleInstantiationStrategy.java:154) ... 86 common frames omitted
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
