File upload spring引导（jetty）捕获上载错误（文件太大）

我正在尝试处理上载文件过大的情况。
将最大文件大小设置为“无限制”不是一个选项。
就我所见，问题在于异常是在spring之外抛出的——在本例中是在jetty中

我在谷歌上搜索了一下，结果显示我应该检查一下是否存在多路径异常

我根本没有看到抛出此异常

所以总的来说，我在这里碰头。如何捕获此异常以显示一个好的错误

多谢各位

编辑：
这闻起来像虫子。
使用tomcat而不是jetty时引发MultipartException
我的代码在tomcat上运行良好

不过，我仍有兴趣与jetty合作。
结束编辑

这是引发的异常（jetty）：

您在tomcat上遇到的

MultipartException

的完整包是什么？（因为servlet或jee规范中没有这样的例外）我不确定，但我认为这可能是Jetty中的一个bug。在Tomcat中，Spring MVC从DispatcherServlet.checkMultipart中抛出一个

MultipartException

。此方法访问请求的所有部分。当其中一个部件太大时，Tomcat会抛出异常，从而触发

MultipartException

。另一方面，Jetty允许SpringMVC检索所有请求部件，即使其中一个超过了最大尺寸。然后，当第二次尝试访问请求的部分时，它会失败，但Spring MVC抛出MultipartException为时已晚。@JoakimErdfelt异常是：嵌套异常是org.springframework.web.multipart.MultipartException:无法解析多部分servlet请求；嵌套异常是java.lang.IllegalStateException:org.apache.tomcat.util.http.fileupload.FileUploadBase$filesIzelimiteExceedeException:MultipartException的字段文件exc..Opened bugpiece@AndyWilkinson添加了另一个更具体的bug，用于在错误发生后检索其余部分的发现-
