Spring MVC3访问HttpServletRequest
我想自己处理请求和会话属性，而不是将其留给 Spring @SessionAttributes，例如用于登录或 cookie 处理。 我只是不知道如何从控制器内访问 HttpRequest 。我需要一种方法来访问 @RequestAttribute 之上的一层并访问 HttpRequest 本身。 Stripes 用于通过实现 ApplicationContext 并调用 getAttribute() 来实现此目的。
另外，将 HttpServletRequest 作为参数传递似乎不起作用：
@RequestMapping(value="/")
public String home(HttpServletRequest request){
System.out.println(""+request.getSession().getCreationTime());
return "home";
}
为什么此方法不打印任何内容？
I would like to handle request and session attributes myself rather than leaving it to Spring @SessionAttributes, for login or cookies handling for example.
I just cannot figure out how to access the HttpRequest from within a controller. I need a way to go a layer above the @RequestAttribute and access the HttpRequest itself.
With Stripes in used to do this by implementing an ApplicationContext and calling getAttribute().
Also, passing the HttpServletRequest as parameter seems not to work:
@RequestMapping(value="/")
public String home(HttpServletRequest request){
System.out.println(""+request.getSession().getCreationTime());
return "home";
}
Why does this method not print anything?

连接调试器并确认您的控制器方法被调用。
检查以下内容：
您是否正在发送 POST 请求？然后需要用方法参数指定方法名：
@RequestMapping(value = "/hello", method = RequestMethod.POST)Spring 通过
正确检测到您的控制器吗？ >@Controller注释？Attach a debugger and confirm that your controller method is called.
Check the following:
Are you sending a POST request? Then you need to specify the method name with the method parameter:
@RequestMapping(value = "/hello", method = RequestMethod.POST)Is your controller properly detected by Spring via the
@Controllerannotation?
