【问题描述】：
我正在做一项任务，我想在 oracle 数据库中上传 excel 数据，但是当我尝试运行代码并上传 .xls 文件后，它给了我文件未找到异常 D:\GODBFILES\NETBEANS PROJECTS\NetBeansProjects\TestWebApplication \build\web\null（系统找不到指定的文件），我担心的是任何位置的文件都应该上传到 db 我在 fileinputstream 中更新了代码，我写了硬编码的路径和文件名，但我不希望此文件路径和文件名应动态获取并存储在文件中
用于上传我在下面的 jar 中使用的文件
commons-fileupload-1.3.jar, commons-io-2.4.jar， poi-3.9.jar, cos.jar, poi-ooxml-3.9.xml

您没有发布任何将上传文件登陆到文件系统的文件上传代码。在上传时看到这个 Q：stackoverflow.com/questions/2422468/…
