我有上传文件到我的应用程序 选项我在我的应用程序上下文文件中使用springframework的掷不同的错误比净::从OncePerRequestFilter（Java +春）ERR_CONNECTION_REFUSED
设置文件大小的限制
<bean id="multipartResolver"
class="org.springframework.web.multipart.commons.CommonsMultipartResolver">
<!-- max upload size in bytes -->
<property name="maxUploadSize" value="41943040" /> <!-- 40MB -->
<!-- max size of file in memory (in bytes) -->
<property name="maxInMemorySize" value="1048576" /> <!-- 1MB -->
</bean>
我CORSFilter一个叫做类扩展OncePerRequestFilter
doFilterInternal(HttpServletRequest request, HttpServletResponse response, FilterChain filterChain) throws ServletException, IOException {
.... more code
catch(NestedServletException err){
if(err.getRootCause() instanceof MaxUploadSizeExceededException) {
response.setStatus(418, StringUtil.getGson().toJson("File must be smaller than" + " 40MB"));
response.getWriter().flush();
response.getWriter().close();
throw err;
}else {
throw err;
}
}
现在，如果我检查响应与网络通信后关闭我知道有这种状态的响应 - 但是当我让它“运行”后关闭 在春天的某个地方的网络错误/状态正在复位 和我所得到的最终是网：ERR_CONNECTION_REFUSED
我一直在使用这种方法
@ExceptionHandler(NestedServletException.class)
@ResponseBody
public UIException handleValidationException(NotValidException ve, HttpServletResponse httpServletResponse) {
LOG.debug(ve.getMessage(), ve);
return new UIException(ve);
}
尝试，但它并没有停在那里

我怎样才能获得网络状态 响应错误(418/file size limit)状态，而不是“ERR_CONNECTION_REFUSED”
它位于堆栈跟踪的顶部。你没有表现，甚至没有说明你是如何得到拒绝的，但可能是因为不适当的重试。解决方案：不要。 – EJP
@EJP 堆栈跟踪来自服务器日志记录 - 客户端没有任何信息发生在服务器上。 我需要在客户端响应这个响应 - 所以他会知道有一个限制 – 2Big2BeSmall
