Is there a static way to get the current HttpServletRequest in Spring

Question

I am using Spring annotations, I can pass the HttpRequestContext from the Controller to the Service.

I am looking for a static way or any better solution than passing RequestContext around.

If you are using spring you can do the following:

public static HttpServletRequest getCurrentHttpRequest(){
    RequestAttributes requestAttributes = RequestContextHolder.getRequestAttributes();
    if (requestAttributes instanceof ServletRequestAttributes) {
        HttpServletRequest request = ((ServletRequestAttributes)requestAttributes).getRequest();
        return request;
    }
    logger.debug("Not called in the context of an HTTP request");
    return null;
}

tie this as a bean? How'd using 'autowired' do here, instead of a static method? – sbsatter Nov 09 '17 at 05:45

Remember to declare `org.springframework.web.context.request.RequestContextListener` as a listener in your `web.xml` for this to work. – dvlcube May 07 '21 at 22:21

Or the java8 way

public static Optional<HttpServletRequest> getCurrentHttpRequest() {
    return Optional.ofNullable(RequestContextHolder.getRequestAttributes())
        .filter(ServletRequestAttributes.class::isInstance)
        .map(ServletRequestAttributes.class::cast)
        .map(ServletRequestAttributes::getRequest);
}

You can replace the filter with `ServletRequestAttributes::isInstance` – andrebrait Mar 05 '20 at 18:16
And you then can add a map to `ServletRequestAttributes::cast` after the filter to avoid the cast on the subsequent map. – andrebrait Mar 05 '20 at 18:17
Neither of those methods exist in Java. – Andrew T Finnell Apr 28 '20 at 15:57
They're members of `Class`, so they should be `ServletRequestAttributes.class::isInstance` and `ServletRequestAttributes.class::cast`. – naomimyselfandi Jun 26 '22 at 01:01

I know, it is already answer. I would like to mark as new update. we can inject HttpServletRequest by using @Autowired. It is working fine at springboot.

@Autowired
private HttpServletRequest httpServletRequest;

For reference, this would be the Kotlin way:

    val currentRequest: HttpServletRequest?
        get() = (RequestContextHolder.getRequestAttributes() as? ServletRequestAttributes)?.request

In response to @andrebrait comments above "Or the Java 8 way", the methods are present on the ServletRequestAttributes.class

    public static Optional<HttpServletRequest> getCurrentHttpRequest() {
        return
            Optional.ofNullable(
                RequestContextHolder.getRequestAttributes()
            )
            .filter(ServletRequestAttributes.class::isInstance)
            .map(ServletRequestAttributes.class::cast)
            .map(ServletRequestAttributes::getRequest);
    }

Does `isInstance` still work with subclasses? – Baptiste Pernet Mar 26 '21 at 15:43
No it does not. You should use `isAssignableFrom`. – Radu Sebastian LAZIN Aug 19 '23 at 22:17

You can add HttpServletRequest as a parameter in controller handler method. Like this:

@GetMapping("/hello")
public String hello(HttpServletRequest request) {
    //...
    return "Hello world!";
}

List of supported controller method arguments and return types can be found here: https://docs.spring.io/spring-framework/docs/current/reference/html/web.html#mvc-ann-methods

This is what works for me:

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