本文对比分析了Jersey和Spring MVC在Tomcat容器中的请求处理流程，从SocketProcessor到Executor线程池，再到各自的具体实现，揭示了两者在业务服务调用上的差异。

jersey和spring mvc两者都基于tomcat 这个web容器，同样经过以下tomcat中NioEndpoint的（利用了JAVA的NIO实现了非阻塞IO，Tomcat默认启动是以这个来启动的）SocketProcessor， NioEndpoint中poller线程监测到一个待处理的socket NIO事件时，会将该事件委托给SocketProcessor，SocketProcessor再把任务对象扔给Executor（线程池）去处理，主要就是调Http11Processor组件来处理请求，Http11Processor读取Channel的数据来生成ServletRequest对象，再往后是执行拦截器和调用servlet容器进行请求处理，主要差别就是表格中绿色背景部分，两者都复写HttpServlet中service(ServletRequest req, ServletResponse res)方法，jersey调用ServletContainer找对应servlet容器，然后调用ApplicationHandler，并最终通过ResourceMethodInvoker找到对应业务服务，spring mvc调用DispatcherServlet，最终通过InvocableHandlerMethod找到对应业务服务
