从 OncePerRequestFilter ( Java + Spring 中抛出不同于 net::ERR_CONNECTION_REFUSED 的错误
Throw different error than net::ERR_CONNECTION_REFUSED from OncePerRequestFilter ( Java + Spring )
我可以选择将文件上传到我的应用程序
我使用 springframework
设置了文件大小限制
在我的应用程序上下文文件中
<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>
我有一个名为 CORSFilter 的 class 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，如果我在收盘后立即使用网络流量检查响应，我知道该响应具有此状态 - 但是当我在收盘后让它 "Run"
spring 某处网络 error/status 正在重置
我最终得到的是 net:ERR_CONNECTION_REFUSED
我试过用这个方法
@ExceptionHandler(NestedServletException.class)
@ResponseBody
public UIException handleValidationException(NotValidException ve, HttpServletResponse httpServletResponse) {
LOG.debug(ve.getMessage(), ve);
return new UIException(ve);
}
但它并没有就此停止

如何获取网络状态的错误(418/file size limit)状态
响应而不是 "ERR_CONNECTION_REFUSED"
取自here
If you try to upload a file size, which exceeded the size limit,
Tomcat will crop it at the default 2mb and reset the connection. To
solve it quickly, put a -1 (unlimited) for maxSwallowSize
可能的解决方案：
- Idea
- 1 Try to put a reasonable limit for the file upload, for example, 11mb (11 x 1024 x 1024 = bytes) in this example
Tomcat/conf/server.xml
<Connector port="8080" protocol="HTTP/1.1"
connectionTimeout="20000"
redirectPort="8443"
maxSwallowSize="11534336" />
2.2 And implement a Javascript to check the file size before the upload.
What about Jetty? Tested with Jetty 9, can’t find out any
maxSwallowSize setting, and it will NOT cause a connection reset if
the file size has exceeded the upload limit.
我可以选择将文件上传到我的应用程序 我使用 springframework
设置了文件大小限制在我的应用程序上下文文件中
<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) -->
