具有 Spring Security 的 Sitemesh 不会重定向到目标 url

Question

我正在将 spring security 与我使用 sitemesh 的 Web 项目集成。我可以打开登录页面，但经过身份验证后，它不会重定向到目标网址。

下面是我的 web 项目中的 web.xml。

</web-app>

以下是来自 AppSecurity 项目的 spring-security.xml。

<security:http auto-config="true" use-expressions="true">

  <security:form-login login-page="/login"
    default-target-url="/index.html" always-use-default-target="true"   
               authentication-failure-url="/loginfailed"
    authentication-success-handler-ref="postSuccessAuthHandler" />

  <security:logout invalidate-session="true" logout-success-url="/app" />

  <!-- <security:remember-me /> -->
  <security:intercept-url pattern="/app" access="isAuthenticated()" />
  <security:intercept-url pattern="/app/**" access="isAuthenticated()" />
  <!-- <security:intercept-url pattern="/acct/app"
       access="isAuthenticated()" /> -->

</security:http>

<!--<bean id="postSuccessAuthHandler"
class="org.springframework.security.web.authentication.SavedRequestAwareAuthentication          SuccessHandler">
<property name="defaultTargetUrl" value="/index.html" />-->

我的 Loginpage.jsp 位于 webapp\WEB-INF\views 中，它由 sitemesh 装饰 -

<div id="mainNav"><div class="navWrapper">
    <ul>
    <li class="${fn:startsWith(menuPath, 'M')? 'selected':'first'}"><a     
       href="${pageContext.request.contextPath}/index.html"><spring:message  
       code="mnu.home" /></a></li>

LoginController.java 处理此问题 -

@RequestMapping(value = "/login", method = RequestMethod.GET)
public String login(ModelMap model) {
   return "loginpage";
}

所以这里的问题是访问 url - http://localhost:8080/acct/app，显示登录页面。身份验证成功后，它会尝试重定向到 http://localhost:8080/acct/app。不知道为什么会发生这种情况，而不是像 default-target-url 中提到的那样发生在 /index.html 上。

tomcat 的日志行显示 -

通过将 DispatcherServlet 映射更改为 / 而不是 /index.html 尝试进行大量调试。将 sitemesh 过滤器映射更改为 /* 而不是 /index.html。 如果与示例 Web 项目（没有 sitemesh）集成，相同的 AppSecurity 项目可以正常工作。 不确定我在 sitemesh 项目中缺少什么。任何帮助都会很棒。

Answer 1

"default-target-url=/index.html" 这将在您成功登录后重定向页面。
例如，您可以重定向到 /home.html 或在控制器中使用 /home.do 在重定向到所需页面之前执行一些逻辑。

@RequestMapping(value = "/home.do", method = RequestMethod.POST)
public String login(ModelMap model) {

   //TODO logic ...
   return "/home.html";
}
