Dispatcher servlet mapping - spring

Question

I am trying to use spring-security
Before all of the configuration
http://localhost:9090/app/login2.xhtml
request, works as i expected.
I added a controller:
#Controller
#RequestMapping("/auth")
public class LoginController {
#RequestMapping(value = "/login", method = RequestMethod.GET)
public String getLoginPage(#RequestParam(value="error", required=false) boolean error,
ModelMap model) {
return "login2.xhtnml";
}
}
I have in web.xml:
<servlet>
<servlet-name>spring</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<init-param>
<param-name>contextConfigLocation</param-name>
<param-value>
classpath:META-INF/spring-servlet.xml
</param-value>
</init-param>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>spring</servlet-name>
<url-pattern>/*</url-pattern>
</servlet-mapping>
With this configuration when i call
http://localhost:9090/app/login2.xhtml
Error comes
WARN org.springframework.web.servlet.PageNotFound - No mapping found for HTTP request with URI [/app/login2.xhtml] in DispatcherServlet with name 'spring'
BUT when i change configuration mapping to
<servlet-mapping>
<servlet-name>spring</servlet-name>
<url-pattern>/app/*</url-pattern>
</servlet-mapping>
http://localhost:9090/app/login2.xhtml works as i expected
but
http://localhost:9090/app/auth/login
gives no error, no exception, no redirection, i think dispatcher servlet can not know about this request.
http://localhost:9090/app/app/auth/login
works with
<servlet-mapping>
<servlet-name>spring</servlet-name>
<url-pattern>/app/*</url-pattern>
</servlet-mapping>
My understanding:
dispatcher servlet use "http://localhost:9090/" as base for searching login2.xhtml
and use "http://localhost:9090/app" for /auth/login URL.
I do not know where to set this, and why they are different.

Have you added the SpringSecurityFilterChain to the web.xml?
<filter>
<filter-name>springSecurityFilterChain</filter-name>
<filter-class>org.springframework.web.filter.DelegatingFilterProxy</filter-class>
</filter>
<filter-mapping>
<filter-name>springSecurityFilterChain</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>
Could you past the registered "Request Bindings" if the container starts (from the logfile)?
