Struts2+Android 多種方式向服務器發送信息

日期：2017/3/1 10:22:21   编辑：Linux編程

還是接上篇 Struts2+Android 實現信息,文件上傳功能

修改了一些VideoManageAction

  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;

  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;
  16. import com.su.action.util.StreamTool;
  20. public class VideoManageAction extends ActionSupport {
  21. private String title;
  22. private String timelength;
  23. private File myFile;
  24. private String myFileFileName;
  25. public String getMethod() {
  26. return method;
  27. }
  29. public void setMethod(String method) {
  30. this.method = method;
  31. }
  33. private String method;
  34. public File getMyFile() {
  35. return myFile;
  36. }
  38. public void setMyFile(File myFile) {
  39. this.myFile = myFile;
  40. }
  42. public String getTitle() {
  43. return title;
  44. }
  46. public void setTitle(String title) {
  47. this.title = title;
  48. }
  50. public String getTimelength() {
  51. return timelength;
  52. }
  54. public void setTimelength(String timelength) {
  55. this.timelength = timelength;
  56. }
  58. public void setMyFileFileName(String myFileFileName) {
  59. this.myFileFileName = myFileFileName;
  60. }
  64. public String getMyFileFileName() {
  65. return myFileFileName;
  66. }
  68. public String execute() throws Exception {
  69. if (method.equals("getXml")) {
  70. InputStream inStream = ServletActionContext.getRequest().getInputStream();
  71. byte[] data = StreamTool.readInputStream(inStream);
  72. String xml = new String(data, "UTF-8");
  73. System.out.println("11111111111111111111");
  74. System.out.println(xml);
  75. }
  76. if (myFile!=null) {
  78. InputStream is = new FileInputStream(myFile);
  79. String uploadPath = ServletActionContext.getServletContext()
  80. .getRealPath("/upload");
  81. File file = new File(uploadPath);
  83. if (!file.exists()) {
  84. file.mkdir();
  87. }
  88. File toFile = new File(uploadPath, this.getMyFileFileName());
  90. OutputStream os = new FileOutputStream(toFile);
  92. byte[] buffer = new byte[1024];
  94. int length = 0;
  96. while ((length = is.read(buffer)) > 0) {
  97. os.write(buffer, 0, length);
  98. }
  100. is.close();
  101. os.close();
  102. }
  103. System.out.println(this.getTimelength()+"\n"+this.getTitle()+"\n");
  104. return SUCCESS;
  106. }
  107. }

這次使用TestCase 用的時候加如activity吧
