springMVC integrated shiro permission authentication framework, the problem Log on to log does not appear after logging

There are two solutions:

1. Configure section of the welcome page in the web.xml file:

<welcome-file-list>
    <welcome-file>/index.do</welcome-file>     
 </welcome-file-list>

 

 2. In the Customize Form Filler MyFormAuthenticationFilter, the add remove shiro visit on sesion stored address shiroSavedReques
