java - Spring Security - 如何启用方法安全注释？

Question

StackOverflow 上有很多类似的问题，但我找不到任何答案:(

我有这样的 web.xml:

<context-param>
    <param-name>contextConfigLocation</param-name>
    <param-value>
        /WEB-INF/spring-security.xml
    </param-value>
</context-param>

<servlet>
    <servlet-name>spring</servlet-name>
    <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
    <load-on-startup>1</load-on-startup>
    <init-param>
        <param-name>contextConfigLocation</param-name>
        <param-value>/WEB-INF/spring-web.xml</param-value>
    </init-param>
</servlet>

<servlet-mapping>
    <servlet-name>spring</servlet-name>
    <url-pattern>/</url-pattern>
</servlet-mapping>

<listener>
    <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>

<filter>
    <filter-name>springSecurityFilterChain</filter-name>
    <filter-class>org.springframework.web.filter.DelegatingFilterProxy</filter-class>
</filter>
<filter-mapping>
    <filter-name>springSecurityFilterChain</filter-name>
    <url-pattern>/*</url-pattern>
    <dispatcher>FORWARD</dispatcher>
    <dispatcher>REQUEST</dispatcher>
</filter-mapping>

并尝试配置 method security带注释。正如我所见，它必须由 <sec:global-method-security pre-post-annotations="enabled"/> 完成，放置在与其他组件相同的上下文中，spring-web.xml在我的情况下。所以我有以下 spring-web.xml :

<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xmlns:sec="http://www.springframework.org/schema/security"
       xsi:schemaLocation="http://www.springframework.org/schema/beans
          http://www.springframework.org/schema/beans/spring-beans-3.0.xsd
          http://www.springframework.org/schema/security
          http://www.springframework.org/schema/security/spring-security-3.0.xsd"
        default-autowire="byName">

    <context:component-scan base-package="com.cleanplates.apiserv"/>
    <sec:global-method-security pre-post-annotations="enabled"/>

</beans>

和spring-security.xml :

<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xmlns:sec="http://www.springframework.org/schema/security"
       xsi:schemaLocation="http://www.springframework.org/schema/beans

加入<sec:global-method-security后的问题所有 Controller 停止工作。我在日志中有以下内容:

PageNotFound:noHandlerFound:947 - No mapping found for HTTP request with URI [/some/page] in DispatcherServlet with name 'spring'

当我删除这个 global-security 时一切正常元素。如果我将它添加到 spring-security.xml 中- 没有什么改变。似乎没有使用它，因为用 @PreAuthorize("hasRole('ROLE_ADMIN')") 注释的方法(或任何其他角色)任何人都可以访问。

PS 我正在使用 Spring 3.0.5.RELEASE 和 Spring Security 3.0.5.RELEASE

Answer 1

启用 <sec:global-method-security> 后spring security 为您的 Controller 创建代理。 spring-mvc 找不到像 @RequestMapping 这样的注释在这种情况下，在 bean 上。如果你想在你的 Controller 上使用安全注释，你应该提取 Controller 的接口(interface)并在其上放置 mvc 注释。 Spring 文档包含以下关于此的注释:

NOTE: When using controller interfaces (e.g. for AOP proxying), make sure to consistently put all your mapping annotations - such as @RequestMapping and @SessionAttributes - on the controller interface rather than on the implementation class.
