登錄后重定向（GAE上的Spring安全性）

Question

我有一些麻煩使我的登錄始終重定向到同一個地方。 我做過這樣的事情

<http auto-config="true" use-expressions="true" entry-point-ref="gaeEntryPoint" >
    <intercept-url pattern="/_ah/login" access="permitAll"/>
    <intercept-url pattern="/**" access="isAuthenticated()"/>
    <custom-filter position="PRE_AUTH_FILTER" ref="gaeFilter"/>
    <form-login authentication-success-handler-ref="authSuccessHandler"/>
</http>

<beans:bean id="authSuccessHandler"
            class="dk.lindhardt.arbejdsfordeling.server.security.AuthenticationSuccessHandlerImpl"/>

和

public class AuthenticationSuccessHandlerImpl implements AuthenticationSuccessHandler {

   public void onAuthenticationSuccess(HttpServletRequest request, HttpServletResponse response, Authentication authentication) 
   throws IOException, ServletException {
       if (authentication != null && authentication.isAuthenticated()) {
           response.sendRedirect(OrganizationListServlet.URL);
       }
   }

 }

它永遠不會進入上述方法。 我怎么做到這一點？

Answer 1

您不應該在那里擁有那個然后執行重定向的servlet。 您可以在配置中進行重定向。

<http auto-config="true">   
    <intercept-url pattern="/app/login" filters="none" />
    <form-login 
        login-page="/app/login" 
        login-processing-url="/app/dologin" 
        authentication-failure-url="/app/login?login_error=1" 
        default-target-url="/app/home"/>
</http>

我想我們可以擴展SimpleUrlAuthenticationSuccessHandler並調用super.onAuthenticationSuccess()方法來使用DefaultRedirectStrategy 。 修改后的代碼將是：

public class AuthenticationSuccessHandlerImpl extends SimpleUrlAuthenticationSuccessHandler {
       @Override
   public void onAuthenticationSuccess(HttpServletRequest request, HttpServletResponse response, Authentication authentication) 
   throws IOException, ServletException {
       if (authentication != null) {
       setDefaultTargetUrl(OrganizationListServlet.URL);
              super.onAuthenticationSuccess(request, response, authentication);
       }

   }

 }

您可以在沒有處理程序的情況下通過向表單登錄設置添加“always-use-default-target”來完成此操作

<form-login default-target-url='/your/target/url.htm' always-use-default-target='true' />

請參閱“設置默認的登錄后目的地”下的http://static.springsource.org/spring-security/site/docs/3.1.x/reference/springsecurity-single.html#ns-form-and-basic

它不漂亮，但我通過在最后位置定位自定義過濾器來解決它。

public void doFilter(ServletRequest request, ServletResponse response, FilterChain filterChain) throws
            IOException, ServletException {
        Authentication authentication = SecurityContextHolder.getContext().getAuthentication();

       if (authentication != null && authentication.isAuthenticated()) {
            User user = (User) authentication.getPrincipal();
            if (user.isLoggingIn()) {
                if (authentication.getAuthorities().contains(AppRole.ROLE_NEW_USER)) {
                    ((HttpServletResponse) response).sendRedirect(RegistrationServlet.URL);
                } else {
                    ((HttpServletResponse) response).sendRedirect("/" + OrganizationListServlet.URL);
                }
                user.setLoggingIn(false);
            } else if (user.isLoggingOut()) {
                ((HttpServletRequest) request).getSession().invalidate();
            }
        }
        filterChain.doFilter(request, response);
}

我認為問題是gaeFilter繞過了正常的登錄過程，因此我不能使用authentication-success-handler。
