Java JERSEY 2.0-多部分@FormDataParam问题

因此，在我介绍我的问题之前，先了解一下web服务。我正在为当地学校建立一项服务，让学生上传课堂讲稿，在开放平台上共享

首先，我在本地机器上运行了一个MySQL实例。我的web服务RESTJersey 2.0连接到我的数据库，可以很好地查询它。我有一个HTML页面，我可以在文本字段中键入一个要搜索的参数，它点击存储过程并按预期返回结果

我有另一个存储过程，它接受输入参数作为表单的一部分，并将新记录插入数据库。这也很成功

我现在想做的是，在我将新记录插入数据库之前，我想将一个文件上载到一个位置，然后在它成功上载之后，将一个关于该上载的记录插入数据库

我有一个HTML表单设置，所有文件都发布在下面。我无法实现所需的多部分内容。我在网上找到的所有示例和教程都没有多大帮助。我不确定JAR中的文件位置在这个版本的JERSEY中是否发生了变化，但我从其他人那里看到的任何东西都不适合我

以下是错误代码：
