If you are using spring you can do the following:
如果您使用的是 spring，您可以执行以下操作：
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;
}

Or the java8 way
或者java8方式
public static Optional<HttpServletRequest> getCurrentHttpRequest() {
return Optional.ofNullable(RequestContextHolder.getRequestAttributes())
.filter(requestAttributes -> ServletRequestAttributes.class.isAssignableFrom(requestAttributes.getClass()))
.map(requestAttributes -> ((ServletRequestAttributes) requestAttributes))
.map(ServletRequestAttributes::getRequest);
}
