Struts2+Android 實現信息,文件上傳功能

繼續Struts2+Android 使用struts2制作做WebService話題,中午實現了獲取WebService今晚是上傳文件 本工程也實現了上傳文字(廢話)可以直接在服務器控制台打印出來

還是第一篇的http://www.linuxidc.com/Linux/2012-05/60917.htm工程

struts增加一個action

1. <?xml version="1.0" encoding="UTF-8" ?>
3. <!DOCTYPE struts PUBLIC
4. "-//Apache Software Foundation//DTD Struts Configuration 2.0//EN"
5. "http://struts.apache.org/dtds/struts-2.0.dtd">
7. <struts>
8. <package name="struts2" extends="struts-default">
9. <action name="getlist" class="com.su.action.VideoListAction">
10. <result name="xml">/videos.jsp</result>
11. <result name="json">/jsonvideos.jsp</result>
12. </action>
13. <action name="upload" class="com.su.action.VideoManageAction">
14. <result name="success">/result.jsp</result>
15. </action>
16. </package>
17. </struts>

然後是測試使用的上傳界面(好大 坑嗲)

1. <s:form action="upload.action" method="post"
2. enctype="multipart/form-data">
3. <table Width="80%" height="60%">
4. <tr>
5. <td Width="20%"></td>
6. <td Width="20%">
7. 資源題目:
8. </td>
9. <td>
10. <input type="text" name="title" Width="80%">
11. </td>
12. <tr>
13. <td Width="20%"></td>
14. <td Width="20%">
15. 資源時長:
16. </td>
17. <td>
18. <input type="text" name="timelength" Width="80%">
19. </td>
20. </tr>
21. <tr>
22. <td Width="20%"></td>
23. <td Width="20%">
24. 上傳文件:
25. </td>
26. <td>
27. <input type="file" name="myFile" Width="80%">
28. </td>
29. </tr>
30. <tr>
31. <td Width="20%"></td>
32. <td Width="20%"></td>
33. <td>
34. <input type="reset" value="!清空內容">
35. <input type="submit" value="上傳">
36. </td>
37. </tr>
38. </table>
39. </s:form>

然後是VideoManageAction.java

1. package com.su.action;
3. import java.io.File;
4. import java.io.FileInputStream;
5. import java.io.FileOutputStream;
6. import java.io.InputStream;
7. import java.io.OutputStream;
8. import java.text.SimpleDateFormat;
9. import java.util.Date;
11. import javax.servlet.http.HttpServletRequest;
12. import javax.servlet.http.HttpServletResponse;
13. import org.apache.struts2.ServletActionContext;
15. import com.opensymphony.xwork2.ActionSupport;
19. public class VideoManageAction extends ActionSupport {
20. private String title;
21. private String timelength;
22. private File myFile;
23. private String myFileFileName;
25. public File getMyFile() {
26. return myFile;
27. }
29. public void setMyFile(File myFile) {
30. this.myFile = myFile;
31. }
33. public String getTitle() {
34. return title;
35. }
37. public void setTitle(String title) {
38. this.title = title;
39. }
41. public String getTimelength() {
42. return timelength;
43. }
45. public void setTimelength(String timelength) {
46. this.timelength = timelength;
47. }
49. public void setMyFileFileName(String myFileFileName) {
50. this.myFileFileName = myFileFileName;
51. }
55. public String getMyFileFileName() {
56. return myFileFileName;
57. }
59. public String execute() throws Exception {
61. InputStream is = new FileInputStream(myFile);
62. String uploadPath = ServletActionContext.getServletContext()
63. .getRealPath("/upload");
64. File file = new File(uploadPath);
66. if (!file.exists()) {
67. file.mkdir();
70. }
71. File toFile = new File(uploadPath, this.getMyFileFileName());
73. OutputStream os = new FileOutputStream(toFile);
75. byte[] buffer = new byte[1024];
77. int length = 0;
79. while ((length = is.read(buffer)) > 0) {
80. os.write(buffer, 0, length);
81. }
83. is.close();
84. os.close();
85. System.out.println(this.getTimelength()+"\n"+this.getTitle()+"\n"+this.getMyFileFileName());
86. return SUCCESS;
88. }
89. }
