处理不是 *** 作请求的分段请求？

这是“模式”，是处理多部分请求的最佳方法

来自视图层的 *** 作请求转到此方法：

@ActionMapping(params = "javax.portlet.action=sample")public void response(MultipartActionRequest request, ActionResponse response) {    response.setRenderParameter("javax.portlet.action", "success");    List<MultipartFile> fileList = request.getFiles("file");}

渲染阶段如下：

@RequestMapping(params = "javax.portlet.action=success")public ModelAndView process(RenderRequest request, Model model) throws IOException {    Map map = new HashMap();    map.put("test", new Integer(1));    return new ModelAndView("someView", map);}

您创建一个“ bean”视图：

@Component("someView")public class SomeView extends AbstractView {    private Logger logger = Logger.getLogger(SomeView.class);    @Override    protected void renderMergedOutputModel(Map map, HttpServletRequest request, HttpServletResponse response) throws Exception {    logger.info("Resolving ajax request view - " + map);    JSonObject jsonObj = new JSonObject(map);    logger.info("content Type = " + getContentType());    response.setContentType("application/json");    response.setCharacterEncoding("UTF-8");    response.getWriter().write(jsonObj.toString());    response.getWriter().flush();    }}

您将BeanNameViewResolver添加到servlet / portlet上下文中：

<bean  p:order="1" />
