java - 文件上传代码出错

Question

我在文件上传代码的 jsp 页面中遇到以下错误:

The method parseRequest(RequestContext) in the type FileUploadBase is not applicable for the arguments (HttpServletRequest)

代码错误:

List<FileItem> items = uploadHandler.parseRequest(request);

Answer 1

parseRequest(RequestContext ctx)期望 RequestContext 实例作为参数，但传递的参数是 HttpServletRequest

的实例

使用ServletRequestContext创建一个 RequestContext 实例，如下所示。

List<FileItem> items 
          = uploadHandler.parseRequest(new ServletRequestContext(request));
