问题描述
我正在 Spring 指南，但我使用 Undertow 作为嵌入式 servlet 而不是默认的 Tomcat.它奏效了.
I'm running the complete version of Spring boot Upload file guide at Spring Guide, but I used Undertow as embedded servlet instead of Tomcat default. And it worked.
当我尝试上传大于配置文件中的值的文件时
When I try to upload file with size larger than the value in config file
spring.http.multipart.max-file-size=128KB
spring.http.multipart.max-request-size=128KB
它引发异常.这是预期的行为
It raises exception. That is expected behavior
使用Tomcat内嵌servlet，可以通过捕获SizeLimitExceededException或MultipartException
With Tomcat embedded servlet, it can be easily handled by catching SizeLimitExceededException or MultipartException
但是对于 Undertow，它会抛出 RuntimeException 事件我在全局处理程序中捕获它:
But with Undertow, it throws RuntimeException event I catch it in global handler:
@ControllerAdvice
public class GlobalControllerExceptionHandler extends ResponseEntityExceptionHandler {
@ExceptionHandler({RuntimeException.class, Exception.class, IOException.class})
ResponseEntity<?> handleControllerException(Exception exc, HttpServletRequest request, Throwable ex) {
return ResponseEntity.status(HttpStatus.INTERNAL_SERVER_ERROR).build();
}
}
异常信息:
java.lang.RuntimeException: java.io.IOException: UT000020: Connection terminated as request was larger than 131072

代码如下:
控制器
@PostMapping("/")
public String handleFileUpload(@RequestParam("file") MultipartFile file,
RedirectAttributes redirectAttributes) {
storageService.store(file);
redirectAttributes.addFlashAttribute("message",
"You successfully uploaded " + file.getOriginalFilename() + "!");
return "redirect:/";
}

有人和我有同样的问题吗?超过最大文件大小上传时如何捕获异常?
Anyone get the same problem with me? How can I catch the exception when maximum file size upload is exceeded?
任何帮助将不胜感激
推荐答案
也许它能够在某些特定情况下提供帮助.
Maybe it is able to help in some particular case.
我在逆流和异常处理方面也有同样的问题.
I have the same problem with undertow and exception handling.
我的情况有点不同，我也有 spring-security，所以当其中一些尝试从请求中读取信息时，spring-security 过滤器会导致像 RequestTooBigException 这样的异常.
My case is a little bit different, I also have spring-security, so the exceptions like RequestTooBigException are caused in spring-security filters when some of them try to read information from the request.
作为一种解决方案，我使用了一个额外的过滤器，该过滤器添加在导致该异常的第一个安全过滤器之前.(对我来说是 BearerTokenAuthenticationFilter.class)
As a solution, I use an additional filter that is added before the first security filter that is caused that exception. (For my it is BearerTokenAuthenticationFilter.class)
有一个额外的过滤器来处理这些异常:
There is an additional filter that handles these exceptions:
@Component
@Slf4j
public class SecurityRequestToBigExceptionHandlerFilter extends OncePerRequestFilter {
@Override
public void doFilterInternal(HttpServletRequest request, HttpServletResponse response,
FilterChain filterChain) throws ServletException, IOException {
try {
filterChain.doFilter(request, response);
} catch (IllegalStateException | RequestTooBigException | MultiPartParserDefinition.FileTooLargeException ex) {
if (ex instanceof RequestTooBigException
|| ex instanceof MultiPartParserDefinition.FileTooLargeException) {
writeResponse(response, ex);
return;
}
Throwable causeException = ex.getCause();
if (nonNull(causeException)
&& (causeException instanceof RequestTooBigException
|| causeException instanceof MultiPartParserDefinition.FileTooLargeException)) {
writeResponse(response, causeException);
return;
}
throw ex;
}
}
private void writeResponse(HttpServletResponse response, Throwable ex) throws IOException {
log.debug("Handle RequestToBig Exception with {}", ex.getMessage());
response.setStatus(HttpStatus.BAD_REQUEST.value());
response.getWriter().write(ex.getMessage());
}
}
接下来我们需要更改的是安全配置.
Next what we need to change is security configuration.
有我的简化安全配置:
@EnableWebSecurity
@RequiredArgsConstructor
public class SecurityConfig extends WebSecurityConfigurerAdapter {
@Autowired
private final SecurityRequestToBigExceptionHandlerFilter requestToBigExceptionHandlerFilter;
@Override
public void configure(HttpSecurity http) throws Exception {
http
.addFilterBefore(requestToBigExceptionHandlerFilter, BearerTokenAuthenticationFilter.class)
.csrf().disable()
.cors()
.and()
.authorizeRequests()
.anyRequest().authenticated()
.and()
.oauth2ResourceServer().jwt();
}
}
