我正在编写一个套接字服务器(无 Web 应用程序!)应用程序,并希望使用基于方法的安全性来处理我的 ACL 需求。我按照我发现的一个小教程进行操作春季安全举例 http://blog.solidcraft.eu/2011/03/spring-security-by-example-securing.html
到目前为止我配置:
<security:global-method-security pre-post-annotations="enabled">
<security:expression-handler ref="expressionHandler" />
</security:global-method-security>
<bean id="expressionHandler" class="org.springframework.security.access.expression.method.DefaultMethodSecurityExpressionHandler">
<property name="permissionEvaluator">
<bean id="permissionEvaluator" class="myPermissionEvaluator" />
</property>
</bean>
<security:authentication-manager id="authenticationmanager">
<security:authentication-provider ref="authenticationprovider" />
</security:authentication-manager>
<bean id="authenticationprovider" class="myAuthenticationProvider" />
使用服务 bean:
@Named
public class ChannelService {
@PreAuthorize("isAuthenticated() and hasPermission(#channel, 'CHANNEL_WRITE')")
public void writeMessage(Channel channel, String message) { ... }
}
一切都编译完毕,应用程序启动并正常工作,但没有访问控制。我的调试日志显示我的评估器从未被调用。
当我尝试类似的东西时@Secured
注释 注释已被评估并且访问被拒绝。但简单的基于角色的安全性不足以满足我的要求。
EDIT做了更多测试:当我仅配置 secure-annotations="enabled" 时,基于角色的安全性有效。当在 ADDITION 中配置 pre-post-annotations="enabled" 时,安全和预授权都不起作用。当我仅配置前后注释时,它仍然不起作用。
EDIT2
更多测试:
仅 secure_annotations="enabled" 对我的通道服务的调用通过 Cglib2AopProxy
一旦我激活前后注释,呼叫就会直接进入通道服务。没有拦截器,没有代理,什么都没有。
我有点绝望了...
EDIT3
我在这里调试记录了我的测试运行是 spring-security 的部分
仅使用 secure-annotations="enabled"

据我了解,这个日志输出 spring 没有意识到我的 bean 需要被代理,所以它们不是,所以我没有得到安全性。
EDIT4
我调试记录了完整的冲刺启动...(这是一大日志),我发现:
2012-04-12 14:40:41,385 INFO [main] o.s.c.s.ClassPathXmlApplicationContext - Bean 'channelService' of type [class mystuff.ChannelService] is not eligible for getting processed by all BeanPostProcessors (for example: not eligible for auto-proxying)
有办法找出原因吗?因为据我了解。因为@preauthorize,bean 应该是合格的。仅使用 secure-annotations="enabled" 我得到一个后处理日志。
