Casting from HttpServletRequest to WebRequest

Question

I've generated a Spring Boot web application using Spring Initializer, embedded Tomcat, Thymeleaf template engine, and package as an executable JAR file.

Technologies used:

Spring Boot 2.0.0.M6 , Java 8, maven

I have this method in 1 of the class

private Map<String, Object> getErrorAttributes(HttpServletRequest request,
                                                   boolean includeStackTrace) {

        RequestAttributes requestAttributes = new ServletRequestAttributes(request);
        return this.errorAttributes.getErrorAttributes(request, includeStackTrace)

    }

But I don't know how to cast from javax.servlet.http HttpServletRequest org.springframework.web.context.request.WebRequest

The method getErrorAttributes(WebRequest, boolean) in the type ErrorAttributes is not applicable for the arguments (HttpServletRequest, 
     boolean)

If anybody is still interested in obtaining a `WebRequest` from a `HttpServletRequest` , here is how: `WebRequest webRequest = new ServletWebRequest(request);` — Dan Manastireanu, Apr 15 '19 at 13:57
And how about vice versa. HttpServletRequest from WebRequest — VIJ, Jul 25 '19 at 05:57

You don't need to cast HttpServletRequest to WebRequest. What you need is using WebRequest in your controller method.

@GetMapping("/endpoint")
public .. endpont(HttpServletRequest request, WebRequest webRequest) {
    getErrorAttributes(request, webRequest, true);
}

And change to your getErrorAttributes method

private Map<String, Object> getErrorAttributes(HttpServletRequest request, WebRequest webRequest,
                                               boolean includeStackTrace) {

    RequestAttributes requestAttributes = new ServletRequestAttributes(request);
    return this.errorAttributes.getErrorAttributes(webRequest, includeStackTrace)

}

You can remove RequestAttributes requestAttributes = new ServletRequestAttributes(request); and the HttpServletRequest from getErrorAtributes aswell — Toofy, Jan 25 '18 at 23:51
