好像没事。授权有效，用户获得角色。我保护了使用注释的方法（例如 @PreAuthorize("hasPermission(#post, 'READ')") ），它有效并且我被拒绝访问。我创建了一个数据库，他在其中描述了用户对对象的权利。我创建了一个数据库，其中包含用户对对象的权限。

我的问题是，在用户授权后，它没有获得权限，即使用户有权反对，他也被拒绝访问。另外，我注意到在用户登录服务器的日志文件后应该得到一个字符串，该字符串将写入他获得的权限，但我没有这样的行。

我的文件片段：

控制器的受保护方法示例

@Override
@RequestMapping(value = "/post/delete.html", method = RequestMethod.GET)
@Transactional
@PreAuthorize("hasPermission(#post, 'READ')")
public String delete(final Post post) {
    //some actions
    return "post/view";
}

可能是什么问题？

升级版。我的问题是错误填写 acl_object_identity

发布使用 ACL（安全方法调用）的代码，并在 Spring 配置文件中突出显示这些类。另外，为什么要将<security:global-method-security />元素放在 MVC 配置文件中？
