項目部署在linux平台，但是值得注意的是在另一個linux平台和本地windwos環境下運作确實正常的，沒有以上報錯。

根據報錯猜測原因可能是出在commons-fileupload這個jar包上，項目中我引用的是1.3.1這個版本。但是我通過eclipse檢視了commons-fileupload1.3.1.jar源碼，發現是有這個方法的，以下為此方法源碼：

public static final boolean isMultipartContent(
            HttpServletRequest request) {
        if (!POST_METHOD.equalsIgnoreCase(request.getMethod())) {
            return false;
        }
        return FileUploadBase.isMultipartContent(new ServletRequestContext(request));
    }
           

我也搞不懂為什麼明明有此方法，卻報告NoSuchMethodError，但是本着一貫的解決問題的方法，我修改了此jar包版本，修改為1.3.3（這是目前我能查到的最高版本）

<dependency>
    <groupId>commons-fileupload</groupId>
    <artifactId>commons-fileupload</artifactId>
    <version>1.3.3</version>
</dependency>
           

然後重新開機項目，意料之中意料之外的好了。。。。。。。。。。。。。。。。。。。然而我到目前為止還是不知道為什麼會發生這個報錯，以及更換版本後為什麼沒有報錯。

另外需要說明一點的是，如果你的項目中有commons-fileupload.jar的别的版本，請删除掉，保證同一項目同一jar包隻有一個版本
