我被@BalusC以下答案JSF 2.0: How to get the URL that is entered in the browser's address bar以限制用户未登录谁的网页过滤器实现JSF - 为受限制的页面
筛选:
public class RestrictPageFilter implements Filter{
FilterConfig fc;
@Override
public void init(FilterConfig filterConfig) throws ServletException {
fc=filterConfig;
}
@Override
public void doFilter(ServletRequest request, ServletResponse response, FilterChain chain) throws IOException, ServletException {
HttpServletRequest httpreq = (HttpServletRequest) request;
HttpServletResponse httpres = (HttpServletResponse) response;
if (httpreq.getUserPrincipal() == null) {
httpreq.getSession().setAttribute("from", httpreq.getRequestURI());
httpres.sendRedirect("/pages/login.xhtml");
} else {
chain.doFilter(request, response);
}
}
@Override
public void destroy() {
// TODO Auto-generated method stub
}
}
的web.xml:
。<security-constraint>
<web-resource-collection>
<web-resource-name>Admin pages</web-resource-name>
<url-pattern>/admin/*</url-pattern>
<url-pattern>/restricted/*</url-pattern>
<http-method>GET</http-method>
<http-method>POST</http-method>
</web-resource-collection>
<auth-constraint>
<role-name>ADMIN</role-name>
</auth-constraint>
</security-constraint>
<security-constraint>
<web-resource-collection>
<web-resource-name>User pages</web-resource-name>
<url-pattern>/restricted/*</url-pattern>
<http-method>GET</http-method>
<http-method>POST</http-method>
</web-resource-collection>
<auth-constraint>
<role-name>ADMIN</role-name>
<role-name>USER</role-name>
</auth-constraint>
</security-constraint>
<!--login-config>
<auth-method>FORM</auth-method>
<realm-name>jdbc-realm</realm-name>
<form-login-config>
<form-login-page>/pages/login.xhtml</form-login-page>
<form-error-page>/pages/error.xhtml</form-error-page>
</form-login-config>
</login-config-->
<filter>
<filter-name>RestrictPageFilter</filter-name>
<filter-class>gov.denis.chanceryweb5.filter.RestrictPageFilter</filter-class>
</filter>
<filter-mapping>
<filter-name>RestrictPageFilter</filter-name>
<url-pattern>/restricted/*</url-pattern>
</filter-mapping>
与GlassFish的web.xml
<glassfish-web-app>
<security-role-mapping>
<role-name>ADMIN</role-name>
<group-name>ADMIN</group-name>
</security-role-mapping>
<security-role-mapping>
<role-name>USER</role-name>
<group-name>USER</group-name>
</security-role-mapping>
境界GlassFish中的GUI控制台:
当访问我的web应用程序,浏览器我认为这出于某种原因?为什么?
指定不知道这是否与“认证”的事情,但你的过滤器不应该与* .xhtml所有页面映射(它会在每一页上被调用包括索引)。你应该只将它映射到我认为索引不是的受限页面上。 – Fallup 2012-04-12 15:55:21
因此我应该将“login.xtml”移出我想限制的页面? – Melissaa 2012-04-12 15:57:09
登录页面应该超出安全限制。你的数据库表是什么样的?您已经拥有了它们,并且正在尝试将它适配到GlassFish中的JDBCRealm? – rbento 2012-04-12 15:59:40
