java - Spring 安全 : @PreAuthorize works only together with @RequestMapping

Question

我有一个 Spring MVC Controller ，想用 Spring Method Security 来保护它。

在下面的示例中有效 - @RequestMapping和@PreAuthorize注释相同的方法:

@Controller
public class MyController {

    @RequestMapping(value = "/test", method = {RequestMethod.POST, RequestMethod.GET})
    @PreAuthorize("isAuthenticated()")
    public ModelAndView handleRequest(HttpServletRequest request, HttpServletResponse response) throws Exception {  
        return test(request, response);
    }

    public ModelAndView test(HttpServletRequest request, HttpServletResponse response) throws Exception {
        ...
    }

在这个例子中它不起作用 - @RequestMapping和@PreAuthorize注释不同的方法:

@Controller
public class MyController {

    @RequestMapping(value = "/test", method = {RequestMethod.POST, RequestMethod.GET})
    public ModelAndView handleRequest(HttpServletRequest request, HttpServletResponse response) throws Exception {  
        return test(request, response);
    }

    @PreAuthorize("isAuthenticated()")
    public ModelAndView test(HttpServletRequest request, HttpServletResponse response) throws Exception {
        ...
    }

这种奇怪行为的原因可能是什么？

Answer 1

在第二个示例中，test 方法直接从 handleRequest 方法调用。 Spring 没有机制来拦截来自同一个类中的方法调用。因此，永远不会调用 @PreAutorize 的代理/AOP 方法启动。
