1. 由于response多次提交或者是由于有页面显示后仍然含请求转向产生的，就是说程序在return之前就已经执行了跳转或者执行过response，之后遇到return的话，程序想再次执行跳转，也就是重定向，这时功能也许会实现了，但是控制台会报错,

java.lang.IllegalStateException: Cannot forward after response has been committedat org.apache.catalina.core.ApplicationDispatcher.doForward(ApplicationDispatcher.java:312)at org.apache.catalina.core.ApplicationDispatcher.forward(ApplicationDispatcher.java:302)at org.springframework.web.servlet.resource.DefaultServletHttpRequestHandler.handleRequest(DefaultServletHttpRequestHandler.java:119)at org.springframework.web.servlet.mvc.HttpRequestHandlerAdapter.handle(HttpRequestHandlerAdapter.java:49)at org.springframework.web.servlet.DispatcherServlet.doDispatch(DispatcherServlet.java:923)at org.springframework.web.servlet.DispatcherServlet.doService(DispatcherServlet.java:852)at org.springframework.web.servlet.FrameworkServlet.processRequest(FrameworkServlet.java:882)at org.springframework.web.servlet.FrameworkServlet.doGet(FrameworkServlet.java:778)

2. 此时抛出的异常由DefaultServletHttpRequestHandler引起,此时可以定义DefaultServletHttpRequestHandler子类进行处理
