我正在尝试在我的spring(3.2.2)mvc app中实现自定义@PreAuthorize
方法。但每当我点击链接时,我都会把我带到实现@PreAuthorize
的控制器方法,它会给我这个错误:

这是我的app-servlet.xml
<security:global-method-security pre-post-annotations="enabled">
<security:expression-handler ref="expressionHandler" />
</security:global-method-security>
<bean id="expressionHandler" class="com.nav.panda.security.PandaMethodSecurityExpressionHandler" />
这些是覆盖
的java文件public class PandaMethodSecurityExpressionHandler extends DefaultMethodSecurityExpressionHandler{
@Override
protected MethodSecurityExpressionOperations createSecurityExpressionRoot(Authentication authentication,
MethodInvocation invocation){
PandaMethodSecurityExpressionRoot root = new PandaMethodSecurityExpressionRoot(authentication);
root.setThis(invocation.getThis());
return root;
}
public class PandaMethodSecurityExpressionRoot implements MethodSecurityExpressionOperations {
private Object filterObject;
private Object returnObject;
private Object target;
public boolean adminOnly() {
System.out.println("Checking admin authority");
return true;
// return this.hasAuthority("ADMIN");
} ... other methods
控制器看起来像这样:
@RequestMapping(value = "/createPandaPage", method = RequestMethod.GET)
@PreAuthorize("adminOnly()")
public ModelAndView handleRequest(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {
return new ModelAndView("admin/createPanda");
}
web.xml:
<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>
</filter-mapping>
我的应用程序中的登录将从我的应用程序填充User对象(具有从db读取的用户权限)。如何传递此用户对象以检查权限?而且,我还需要做些什么来实现这个目标呢?
答案 0 :(得分:3)
导致调用此方法的请求需要通过Spring Security过滤器链,否则在检查权限时将没有可用的安全上下文。
在没有看到堆栈跟踪的其余部分的情况下,我不能说100%,但看起来这就是这里发生的事情,因为您看到了异常(如果您搜索错误消息,您应该找到类似的问题)。 / p>
因此,您需要确保安全过滤器链处理您想要保护的所有请求,并确保您的过滤器链已正确配置(如果您正在使用命名空间,则应该自动配置)。
