SpringBoot Expose property to set strictServletCompliance on StandardServletMultipartResolver

https://github.com/spring-projects/spring-boot/blob/d9af7cec141190fb32e20de6a64c2d3b03b644e4/spring-boot-project/spring-boot-autoconfigure/src/main/java/org/springframework/boot/autoconfigure/web/servlet/MultipartAutoConfiguration.java#L74C47-L74C47

the Odata standard $batch request use multipart/mixed;boundary=<uuid>, but currently springboot MultipartAutoConfiguration autoconfigure not provide the configure properties to config strictServletCompliance field, which will result in this.multipartResolver.isMultipart(request) return true and the request mark as file upload request and result in bug

    protected HttpServletRequest checkMultipart(HttpServletRequest request) throws MultipartException {
        if (this.multipartResolver != null && this.multipartResolver.isMultipart(request)) {
            if (WebUtils.getNativeRequest(request, MultipartHttpServletRequest.class) != null) {
                if (DispatcherType.REQUEST.equals(request.getDispatcherType())) {
                    logger.trace("Request already resolved to MultipartHttpServletRequest, e.g. by MultipartFilter");
                }
            }
            else if (hasMultipartException(request)) {
                logger.debug("Multipart resolution previously failed for current request - " +
                        "skipping re-resolution for undisturbed error rendering");
            }
            else {
                try {
                    return this.multipartResolver.resolveMultipart(request);
                }
                catch (MultipartException ex) {
                    if (request.getAttribute(WebUtils.ERROR_EXCEPTION_ATTRIBUTE) != null) {
                        logger.debug("Multipart resolution failed for error dispatch", ex);
                        // Keep processing error dispatch with regular request handle below
                    }
                    else {
                        throw ex;
                    }
                }
            }
        }
        // If not returned before: return original request.
        return request;
    }

Thanks for the suggestion. In the meantime you can add a StandardServletMultipartResolver bean to your own configuration:

@Bean(name = DispatcherServlet.MULTIPART_RESOLVER_BEAN_NAME)
public StandardServletMultipartResolver multipartResolver(MultipartProperties multipartProperties) {
    StandardServletMultipartResolver multipartResolver = new StandardServletMultipartResolver();
    multipartResolver.setResolveLazily(multipartProperties.isResolveLazily());
    multipartResolver.setStrictServletCompliance(true);
    return multipartResolver;
}

As there's a fairly straightforward workaround, I'm not sure that this needs to go in 3.2.x. We can bring it forward if someone has some time, but I think 3.x is better for now.

I'd like to handle it.
