我正在使用 spring security..

我有两个页面 1) 欢迎 - 访问所有人 2) admin - 只能由管理员访问

当我尝试访问管理页面时，它抛出 500 错误。

如何解决错误？

(是否需要附加任何文件？)

Answer 1

如果您正在使用 Spring security 4.0，您应该使用 hasRole('ROLE_ADMIN')。并使用 "use-expressions=true"

所以改成

<http auto-config="true" use-expressions="true">
    <intercept-url pattern="/admin**" access="hasRole('ROLE_ADMIN')" />
</http>

它会很好地工作。
