jsf过滤器似乎无法正常工作

我试图用jsf创建一个安全的登录页面，并且我使用了这些代码段作为解决方案，可以在this question中找到。我的问题是，无需登录即可访问/restricted/secret.xhtml，没有重定向，就像没有应用过滤器，因为如果我直接进入/restricted/secret.xhtml，则＃{user.loggedIn }的计算结果为false，但我仍然可以查看该页面。这是我的代码:

AuthFilter.java

public class AuthFilter implements Filter {

private FilterConfig config;

@Override
public void destroy() {
    this.config = null;
}

@Override
public void doFilter(ServletRequest req, ServletResponse resp,
        FilterChain ch) throws IOException, ServletException {

    HttpSession s =  ((HttpServletRequest) req).getSession();
    if (s.getAttribute(UserBean.CREDENTIAL)==null)
    {
        ((HttpServletResponse) resp).sendRedirect("/login.faces");
    }else
    {
        ch.doFilter(req, resp);
    }
}
@Override
public void init(FilterConfig config) throws ServletException {
    this.config = config;
}
}

UserBean.java
@ManagedBean(name="user")
@SessionScoped
public class UserBean implements Serializable {

private String name;
private String password;
protected static final String CREDENTIAL = "ontherun";

private static final long serialVersionUID = 1L;

public String getName()
{
    return this.name;
}

public void setName(String newName)
{
    this.name = newName;
}

public String getPassword()
{
    return this.password;
}

public void setPassword(String newPassword)
{
    this.password = newPassword;
}

public boolean isLoggedIn()
{
    return FacesContext.getCurrentInstance().getExternalContext()
            .getSessionMap().get(CREDENTIAL) != null;
}

public String logout() {
    FacesContext.getCurrentInstance().getExternalContext().getSessionMap().remove(CREDENTIAL);
    return null;
}


public String login()
{
    FacesContext.getCurrentInstance().getExternalContext().getSessionMap().put(CREDENTIAL, this.name);
    return "secret";
}
}

这是我的login.xhtml;该页面可以正常工作，因此模板文件没有问题。

                You are logged in : #{user.loggedIn}

            </p>
        </h:form>
 </ui:define>
 </ui:composition>

这是应该限制的secret.xhtml:

<html   xmlns="http://www.w3.org/1999/xhtml"

<body>
<ui:composition template="/templates/masterLayoutTemplate.xhtml">
 <ui:define name="windowTitle">
     #{msgs.window_title}
 </ui:define>


 <ui:define name="content">
        <h:head></h:head>
        <h:body>
            <p>You are #{user.loggedIn}</p>
        </h:body>


 </ui:define>
 </ui:composition>
</body>
</html>

我的目录结构如下所示:dirStruct 2

最佳答案

您已将FacesServlet映射到/faces/*而不是*.xhtml上。因此，所有JSF请求在URL中都将带有/faces前缀。但是，您已经将AuthFilter映射到/restricted/*而不是/faces/restricted/*上，因此它将永远不会出现在/faces/* URL上。

您可以通过以下两种方法解决此问题:

  • 将FacesServlet映射到*.xhtml而不是/faces/*上。这样做的另一个好处是，当最终用户有意从浏览器地址栏中的URL中删除/faces路径时，最终用户将永远无法看到原始的JSF源代码。
  • 将AuthFilter映射到/faces/restricted/*而不是/restricted/*上。

    • 我个人建议第一种方法。您最终得到了一个较短且更好的URL，并且立即还防止了JSF源代码泄漏。
