Validation of the application resource model has failed during application initialization.

使用Jersey 2进行文件上传。 需要添加Multipart功能，即在web.xml中的Jersey servlet配置文件中：

<init-param>    <param-name>jersey.config.server.provider.classnames</param-name>    <param-value>org.glassfish.jersey.filter.LoggingFilter;org.glassfish.jersey.media.multipart.MultiPartFeature</param-value></init-param>
