How do I get a HttpServletRequest in my spring beans?

Question

I'm developing an app with a Flex-based front end and a Spring/Hibernate back-end.

To get Facebook integration working in the way I've got it currently, I need to read the cookies set in javascript on the front end on the back-end and do some validation during login to see whether the user is attempting to spoof his Facebook login.

This would be pretty easy, but I can't figure out how to get the HttpServletRequest. I'm using a pretty basic Spring config (this is my first real Spring app, and I'm pretty familiar with it now, but there's lots to it I've never looked at.)

I'm not using Spring MVC or Spring WebFlow or anything like that. I can get the ServletContext, but I haven't yet figured out how to get the request.

Any help?

Solution 1

If FlexContext is not available:

Solution 1: inside method (>= Spring 2.0 required)

HttpServletRequest request = 
        ((ServletRequestAttributes)RequestContextHolder.getRequestAttributes())
                .getRequest();

Solution 2: inside bean (supported by >= 2.5, Spring 3.0 for singelton beans required!)

@Autowired
private HttpServletRequest request;

Solution 2

This is kind of Flex/BlazeDS specific, but here's the solution I've come up with. Sorry if answering my own question is a faux pas.

    HttpServletRequest request = flex.messaging.FlexContext.getHttpRequest();

    Cookie[] cookies = request.getCookies();

    for (Cookie c:cookies)
    {
        log.debug(String.format("Cookie: %s, %s, domain: %s",c.getName(), c.getValue(),c.getDomain()));
    }

It works, I get the cookies. My problem was looking to Spring - BlazeDS had it. Spring probably does too, but I still don't know how to get to it.

Solution 3

@eeezyy's answer didn't work for me, although I'm using Spring Boot (2.0.4) and it may differ, but a variation here in 2018 works thus:

@Autowired
private HttpServletRequest request;

Solution 4

this should do it

((ServletRequestAttributes)RequestContextHolder.getRequestAttributes()).getRequest().getRequestURI();

Solution 5

The @Context annotation (see answers in this question :What does context annotation do in Spring?) will cause it to be injected for you.

I had to use

@Context
private HttpServletRequest request;
