Extjs上传文件到服务器JAVA后台代码如何实现

[climb_ll]

var fpFileUpload1=new Ext.FormPanel({
    id:'fpFileUpload1',
    frame:true,
    fileUpload:true,
    items:[
        {
            xtype:'textfield',
            allowBlank:false,
            fieldLabel:'选择文件',
            inputType:'file',
            name:'fileName'
        }
    ],
    buttonAlign:'center',
    buttons:[
        {
            text:'上传',
            handler:function(){
                if(fpFileUpload1.form.isValid()){
                    fpFileUpload1.form.submit({
                        method:'post',
                        url:'/GIMS/login.do?mtd=uploadFontFile',
                        waitMsg:'文件上传中...',
                        success: function() {
                            Ext.Msg.alert("系统提示", "文件上传成功！");
                        },
                        failure: function() {
                            Ext.Msg.alert("系统提示", "文件上传失败！");
                        }
                    });
                }else{
                    Ext.Msg.alert("系统提示","请选择文件后再上传！");
                }
            }
        },
        {
            text:'取消',
            handler:function(){
                winFielUpload1.hide();
            }
        }
    ]
});
var winFielUpload1=new Ext.Window({
    id:'win1',
    title:'文件上传',
    width:350,
    height:100,
    layout:'fit',
    autoDestory:true,
    modal:true,
    closeAction:'hide',
    items:[
        fpFileUpload1
    ]
});

String fontFilesProperties = request.getSession().getServletContext().getRealPath("/")+"resources/path.properties";
				 System.out.println(fontFilesProperties);
				 Properties pro = new Properties();
				 String fontFilePath = "";
				 try {
					 pro.load(new FileInputStream(fontFilesProperties));
					 fontFilePath = pro.getProperty("fontFilePath");//字体文件存放路径
					 
					 File file = null;
					 // 检查我们有一个文件上传请求
				      boolean isMultipart = ServletFileUpload.isMultipartContent(request);
				      System.out.println(isMultipart);
				      response.setContentType("text/html");
				      
				      DiskFileItemFactory factory = new DiskFileItemFactory();
				      // 文件大小的最大值将被存储在内存中
				      factory.setSizeThreshold(50*1024*1024);
				      // Location to save data that is larger than maxMemSize.
				      factory.setRepository(new File("c:\\temp"));

				      // 创建一个新的文件上传处理程序
				      ServletFileUpload upload = new ServletFileUpload(factory);
				      // 允许上传的文件大小的最大值
				      upload.setSizeMax( 4*1024*1024 );

				   // 解析请求，获取文件项
				      List fileItems = upload.parseRequest(request);
					
				      // 处理上传的文件项
				      Iterator i = fileItems.iterator();
				      while ( i.hasNext () ){
				         FileItem fi = (FileItem)i.next();
				         if ( !fi.isFormField () ){
				            // 写入文件
                           fileName =  new String(fi.getName().getBytes("GBK"), "UTF-8");
				            if( fileName.lastIndexOf("\\") >= 0 ){
				                file = new File( fontFilePath + 
				                fileName.substring( fileName.lastIndexOf("\\"))) ;
				            }else{
				            	file = new File( fontFilePath + 
				                fileName.substring(fileName.lastIndexOf("\\")+1)) ;
				            }
				            fi.write( file ) ;
				         }
				      }
				 }catch (Exception e) {
					e.printStackTrace();
				 }

检查文件上传请求是有的，获取文件项没有。已截图。刚接触EXT完全懵逼 ，求大神解答

应该是上传的文件被拦截了，看一下配置文件怎么写的
