at java.lang.Thread.run(Thread.java:662)代碼如下：
DiskFileItemFactory factory = new DiskFileItemFactory();//文件項工廠
ServletFileUpload sfu = new ServletFileUpload(factory);
System.out.println(sfu.isMultipartContent(request));
sfu.setFileSizeMax(2*1024*1024*1024);//單個文件大小限制2G
sfu.setSizeMax(4*1024*1024*1024);//總文件大小限制4G發現異常：
the request was rejected because its size (5309) exceeds the configured maximum (0) 這句話說明我設置的文件限制大小爲0，可我設置的是2*1024*1024*1024（2G）於是看了<pre name="code" class="java">sfu.setFileSizeMax(2*1024*1024*1024)這個方法，參數是一個long型的值，而我傳入的是int型的值，強轉變成0了， 所以改爲<pre name="code" class="java">sfu.setFileSizeMax((long)2*1024*1024*1024) 解決問題！
