SPRING MVC3.2案例讲解--fileupload

SRPING MVC 的文件上传：

 

XML配置

<!-- Only needed because we require fileupload in the org.springframework.samples.mvc.fileupload package -->
	<beans:bean id="multipartResolver" class="org.springframework.web.multipart.commons.CommonsMultipartResolver" />

 

 

JAVA代码：

 

@Controller
@RequestMapping("/fileupload")
public class FileUploadController {

	@ModelAttribute
	public void ajaxAttribute(WebRequest request, Model model) {
		model.addAttribute("ajaxRequest", AjaxUtils.isAjaxRequest(request));
	}

	@RequestMapping(method=RequestMethod.GET)
	public void fileUploadForm() {
	}

	@RequestMapping(method=RequestMethod.POST)
	public void processUpload(@RequestParam MultipartFile file, Model model) throws IOException {
		
		model.addAttribute("message", "File '" + file.getOriginalFilename() + "' uploaded successfully " + file.getSize()+file.toString());
	}
	
}

 另外，AJAX只可以接收任何形式的文本文档，无法处理二进制文件流，所以ajaxForm 在处理文件上传时使用了一个伪AJAX方法（利用隐藏的IFRAME返回文件上传结果，模拟AJAX效果实现）
