1.spring_fileupload.xml配置文件如下:

Xml代码

1. <bean id="multipartResolver" class="org.springframework.web.multipart.commons.CommonsMultipartResolver">
2. <!--<property name="maxUploadSize" value="10485760"></property>-->
3. </bean>

2.FileUploadAction控制器如下:

Java代码

1. @RequestMapping(params = "method=up", method = RequestMethod.POST)
2. @ResponseBody
3. public Map<String, String> uploadSolver(@RequestParam MultipartHttpServletRequest request {
4. Map<String,String> info = new HashMap<String,String>();
5. MultipartFile patch = request.getFile("file");
6. if (!patch.isEmpty()) {
7. try {
8. String fileName = patch.getOriginalFilename();
10. /**
11. * 获取文件后缀
12. */
13. System.out.println(fileName);
14. String suffix = fileName.substring(fileName.lastIndexOf("."));
16. /**
17. * 判断上传的文件格式是否正确
18. */
19. if ((".zip.rar.gz.tar.bz2.txt".indexOf(suffix.toLowerCase()) != -1)) {
20. Integer fileSize = (int) patch.getSize() / 1024;
22. /**
23. * 如果文件小于10M，则上传文件，否则提示用户不能超过10M
24. */
25. if (fileSize <= 10240) {
27. String uploadPath = ClassLoaderUtil.getProperties("uploadFile.properties").getProperty("filePath");
28. System.out.println(uploadPath);
29. File filePath = new File(request.getSession()
30. .getServletContext().getRealPath(uploadPath));
31. System.out.println(filePath.getAbsolutePath());
32. /**
33. * 判读存储文件路是否存在，不存在则创建
34. */
35. if (! filePath.exists()) {
36. filePath.mkdirs();
37. System.out.println("上传文件路径不存在，创建成功！");
38. }
39. /**
40. * 文件开始上传到服务器上
41. */
42. patch.transferTo(new File(filePath.getAbsolutePath()+"\\"+fileName));
43. info.put("success", "true");
44. info.put("msg", "上传成功！");
46. } else {
47. System.out.println("上传的文件太大，文件大小不能超过10M");
48. info.put("success","false");
49. info.put("msg", "上传的文件太大，文件大小不能超过10M");
50. }
51. } else {
52. System.out.println("上传的文件格式不支持");
53. info.put("success","false");
54. info.put("msg", "上传的文件格式不支持");
56. }
57. } catch (IOException e) {
58. e.printStackTrace();
59. System.out.println("系统异常");
60. info.put("success","false");
61. info.put("msg", "系统异常");
62. }
63. }
64. return info;
65. }

@RequestMapping(params = "method=up", method = RequestMethod.POST)	@ResponseBody	public Map
    
      uploadSolver(@RequestParam MultipartHttpServletRequest request {		Map
     
       info = new HashMap
      
       ();		MultipartFile patch = request.getFile("file");		if (!patch.isEmpty()) {			try {				String fileName = patch.getOriginalFilename();				/**				 * 获取文件后缀				 */				System.out.println(fileName);				String suffix = fileName.substring(fileName.lastIndexOf("."));				/**				 * 判断上传的文件格式是否正确				 */				if ((".zip.rar.gz.tar.bz2.txt".indexOf(suffix.toLowerCase()) != -1)) {					Integer fileSize = (int) patch.getSize() / 1024;					/**					 * 如果文件小于10M，则上传文件，否则提示用户不能超过10M					 */					if (fileSize <= 10240) {						String uploadPath = ClassLoaderUtil.getProperties("uploadFile.properties").getProperty("filePath");						System.out.println(uploadPath);						File filePath = new File(request.getSession()								.getServletContext().getRealPath(uploadPath));						System.out.println(filePath.getAbsolutePath());						/**						 * 判读存储文件路是否存在，不存在则创建						 */						if (! filePath.exists()) {							filePath.mkdirs();							System.out.println("上传文件路径不存在，创建成功！");						}						/**						 * 文件开始上传到服务器上						 */						patch.transferTo(new File(filePath.getAbsolutePath()+"\\"+fileName));						info.put("success", "true");						info.put("msg", "上传成功！");					} else {						System.out.println("上传的文件太大，文件大小不能超过10M");						info.put("success","false");						info.put("msg", "上传的文件太大，文件大小不能超过10M");					}				} else {					System.out.println("上传的文件格式不支持");					info.put("success","false");					info.put("msg", "上传的文件格式不支持");									}			} catch (IOException e) {				e.printStackTrace();				System.out.println("系统异常");				info.put("success","false");				info.put("msg", "系统异常");			}		}		return info;	}
      
     
    

3.前端表单使用Extjs 如下：

Js代码

1. Ext.onReady(function (){
3. var addFileTextField = new Ext.form.TextField({
4. name:'file',
5. allowBlank:false,
6. //使用HTML中的filetext
7. inputType:'file'
9. });
12. var addFileFormPanel = new Ext.form.FormPanel({
13. autoDestory:true,
14. fileUpload:true,
15. frame:true,
16. width:300,
17. autoHeight:true,
18. labelAlign:'right',
19. labelWidth:60,
20. defaultType:'textfield',
21. defaults:{width:200,allowBlank:false},
23. items: [addFileTextField]
24. });
27. var addFileWindow = new Ext.Window({
28. id : "addFileWindow",
29. title : "上传文件",
30. width : 640,
31. height : 200,
32. resizable : false,
33. modal : true,
34. maximizable : false,
35. closeAction : "hide",
36. constrain : true,
37. layout : "vbox",
38. animateTarget:'target',
39. layoutConfig:{
40. align: "stretch"
41. },
42. items : [addFileFormPanel],
43. buttons:[
44. {text:'上传',handler:function (){
45. if(! addFileFormPanel.getForm().isValid()) {
46. return false;
47. }
48. //上传
49. addFileFormPanel.getForm().submit({
50. url:'uploadFile.do?method=up',
51. waitMsg: '正在上传...',
52. success: function (form,response){
53. Ext.Msg.alert('success',response.result.msg);
54. },
55. failure: function (form,response){
56. Ext.Msg.alert('error',response.result.msg);
57. }
58. });
59. }
60. }
61. ]
62. });
63. });
