Spring Security alters request URI

Question

I integrated Spring Security into an existing Spring Boot project (Version: 1.5.3.RELEASE).

Before the integration, we've got our redirect informations from a request via getRequestURI in a preHandle method which extends HandlerInterceptorAdapater.

The Request URI is correctly pointing to their path (for example: /admin/login).

After the integration, the request URI is pointing to the complete path of the jsp.

In addition, we've registered a ContextUtil class to ConfigurableApplicationContext for further URI checkings. In this class, we fetch the request like this:

public HttpServletRequest getCurrentRequest()
{
    final ServletRequestAttributes servletRequestAttributes = 
    (ServletRequestAttributes) 
    RequestContextHolder.currentRequestAttributes();
    return servletRequestAttributes.getRequest();
}

but the URI is also to its "physical path" under /WEB-INF/

For example: GET Request is pointing to /WEB-INF/pages/admin/admin_login.jsp:

My WebSecurityConfig Class is :

@Configuration
@EnableWebSecurity
public class WebSecurityConfig extends WebSecurityConfigurerAdapter
{
    @Override
    protected void configure(HttpSecurity http) throws Exception
    {
        //jeden Aufruf akzeptieren. Authorisierung und 
    Authentifizierung von Spring Security wird nicht genutzt
    http.authorizeRequests().antMatchers("/").permitAll();
}

    @Override
    public void configure(WebSecurity web) throws Exception
    {
    web.ignoring().antMatchers("/resources/**", "/css/**", "/js/**", 
    "/img/**", "resources/*", "/WEB-INF/**").and().debug(true);
    }
}

Relevant applicationContext.xml parts:

<mvc:default-servlet-handler/>
<mvc:annotation-driven/>
<mvc:resources mapping="/resources/**" location="classpath:/WEB-INF/resources/" />

<mvc:interceptors>
    <bean class="org.springframework.web.servlet.i18n.LocaleChangeInterceptor">
        <property name="paramName" value="lang" />
    </bean>
    <bean class="de.abc.xyu.zzz.interceptor.RedirectInterceptor" />
</mvc:interceptors>

<bean id="viewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver">
    <property name="viewClass" value="org.springframework.web.servlet.view.JstlView" />
    <property name="prefix" value="/WEB-INF/pages/" />
    <property name="suffix" value=".jsp" />
    <property name="redirectHttp10Compatible" value="false" />
</bean>

Why is the request pointing to its physical path under /WEB-INF/pages/login.jsp instead of its resolved path and how can we achieve it, that we get the "correct" URI?

Answer 1

Eventually this worked for me:

final ServletRequestAttributes servletRequestAttributes = 
    (ServletRequestAttributes) RequestContextHolder.currentRequestAttributes();

System.out.println("REQUEST URI: " +
     servletRequestAttributes.getRequest()
         .getAttribute("javax.servlet.forward.request_uri"));

That gives the real request URI, not its "physical path" under /WEB-INF/.
