SpringSecurity3.X--一个简单实现

SpringSecurity3.X--前台与后台登录认证

SpringSecurity3.X--remember-me

SpringSecurity3.X--验证码

 

前面给出了一个简单的应用

SpringSecurity3.X--一个简单实现

 

不过一般我们在管理系统时都会分前台与后台,也就是说,前台与后台的登录入口与注销地址都是不一样的,那么该如何使用SpringSecurity实现呢,参考了一些网络上的例子,将之前的小应用做了如下修改:

说明:

1.为了实现不同的登录验证,这里显示声明了登录过滤器与注销过滤器,并指定相应过滤器的位置。

2.因为我们自己来指定了登录过滤器与注销过滤器,所以就不能在<http>中设置auto-config="true"

3.为了区分开不同的登录页面,就需要在<http>中配置认证切入点“entry-point-ref”,认证切入点的作用是当请求被拦截时该如何处理,这里处理为跳转到各自的登录页面

4.这里理想化的将前台用户与后台用户都使用同一个userService进行管理,即表示都存储在同一张用户表中,对于前后台用户不在同一张表中的处理,笔者也在研究中。

 

LoginUrlEntryPoint.java

public class LoginUrlEntryPoint implements AuthenticationEntryPoint {

    public void commence(HttpServletRequest request, HttpServletResponse response,
              AuthenticationException authException) throws IOException, ServletException {
        String targetUrl = null;
        String url = request.getRequestURI();
  
        if(url.indexOf("admin") != -1){
            //未登录而访问后台受控资源时,跳转到后台登录页面
            targetUrl = "/admin/login.do";
        }else{
            //未登录而访问前台受控资源时,跳转到前台登录页面
            targetUrl = "/login.do";
        }
  
        targetUrl = request.getContextPath() + targetUrl;
        response.sendRedirect(targetUrl);
    }

}

你好,能不能提供源代码看看嘛
2 楼 gaoyoubo 2013-06-25  
您好, 看了你的文章,我有一个疑问。
<!-- 登录过滤器 --> 
        <custom-filter before="FORM_LOGIN_FILTER" ref="loginFilter"/> 
        <custom-filter position="FORM_LOGIN_FILTER" ref="adminLoginFilter"/> 
 
        <!-- 注销过滤器 --> 
        <custom-filter before="LOGOUT_FILTER" ref="logoutFilter"/> 
        <custom-filter position="LOGOUT_FILTER" ref="adminLogoutFilter"/> 


这么配置的话,我们程序在执行的时候怎么判断该调用前台登录过滤器、还是后台登录过滤器呢?  注销操作也是一样,怎么来判断呢? 盼回复! 谢谢!

   猜想,关于2张表的想法,能不能从userService里解决。毕竟用户的信息还是通过这里获取的,然后才当前需要的权限进行比较~
