java - spring-security 访问被拒绝异常

Question

我在使用 @secured of spring-security 注释的方法时遇到问题

@Secured(value = { "LIST_GIFT" })

该方法已放置在 spring-mvc web 应用程序的 Controller 方法上。

当我通过 UserDetailsS​​ervice 实现进行调试时，我们在 loadByUserName 方法的末尾有以下 UserDetails 对象:

SecurityDetails [userId=106, username=john@doe.com, enabled=true, accountNonLocked=true, accountNonExpired=true, credentialsNonExpired=true]

具有以下授权权限列表:

[LOCK_SERIAL, CALCULATE_BALANCE, REGISTER_FOR_PUSH_NOTIFICATION, TOPUP_BY_POS, LIST_PRODUCTS, LIST_COUPON_ASSIGNMENT, BALANCE, BALANCE_HISTORY, LIST_GIFT, LIST_PROGRAMS, ASSIGN_COUPON, DISTRIBUTE_COUPON, CAN_CONFIGURE_GIFTS]

HTTP 总是返回 403 Forbidden。当我打开日志记录时，我看到以下内容:

我不知道为什么会发生这种情况。

看起来您拥有的所有 AccessDecisionVoter 都没有投票授予访问权限(他们都弃权)，因此您被拒绝访问。

原因是，默认情况下，作为默认配置一部分的 RoleVoter 只会响应以前缀“ROLE_”开头的权限。因为你们都没有，所以它找不到任何它知道的东西。 This FAQ has some more information .

另一种方法是启用基于表达式的安全性并使用 @PreAuthorize annotation相反，哪个更灵活。有点像

@PreAuthorize("hasRole('LIST_GIFT')")

如果您按照描述启用注释，应该开箱即用。
