目标：选择文件、上传，存session,读取
选择
1.环境：sturts+action
上传：
<form action="BannerAction.action" method="post" enctype="multipart/form-data"> <table width="100%" border="0" cellspacing="0" cellpadding="0"> <tr> <td>选择文件：</td><td><input type="file" name="myFile" class="myFile" /></td> </tr> <tr> <td ><input type="submit" value="上传" /> <input type="reset" value="重置" /></td> </tr> </table> </form>
2.action 存取目录，并存session 值
package com.action; import java.io.File; import java.io.FileInputStream; import java.io.FileOutputStream; import java.io.InputStream; import java.io.OutputStream; import java.io.PrintWriter; import javax.servlet.http.HttpServletResponse; import javax.servlet.http.HttpSession; import org.apache.commons.io.FileUtils; import org.apache.struts2.ServletActionContext; import com.opensymphony.xwork2.ActionSupport; import com.util.OSSUtils; /** * 首页轮回图片上传 * @author caipei * */ public class BannerAction extends ActionSupport{ // myFile属性用来封装上传的文件 private File myFile; // myFileContentType属性用来封装上传文件的类型 private String myFileContentType; // myFileFileName属性用来封装上传文件的文件名 private String myFileFileName; //获得myFile值 public File getMyFile() { return myFile; } //设置myFile值 public void setMyFile(File myFile) { this.myFile = myFile; } //获得myFileContentType值 public String getMyFileContentType() { return myFileContentType; } //设置myFileContentType值 public void setMyFileContentType(String myFileContentType) { this.myFileContentType = myFileContentType; } //获得myFileFileName值 public String getMyFileFileName() { return myFileFileName; } //设置myFileFileName值 public void setMyFileFileName(String myFileFileName) { this.myFileFileName = myFileFileName; } public String execute() throws Exception { HttpServletResponse response=null; response=ServletActionContext.getResponse(); response.setContentType("text/html;charset=UTF-8"); response.setCharacterEncoding("UTF-8"); PrintWriter out=response.getWriter(); //创建session对象 HttpSession session=ServletActionContext.getRequest().getSession(); if (session.getAttribute("id")==null) { out.print("<script lanaguage='javascript'>alert('请重新登录');window.location='login.jsp';></script>"); out.flush(); out.close(); return null; } //基于myFile创建一个文件输入流 InputStream is = new FileInputStream(myFile); // 设置上传文件目录 String uploadPath = ServletActionContext.getServletContext() .getRealPath("/upload"); // 设置目标文件 File toFile = new File(uploadPath, this.getMyFileFileName()); // 创建一个输出流 OutputStream os = new FileOutputStream(toFile); //设置缓存 byte[] buffer = new byte[1024]; int length = 0; //读取myFile文件输出到toFile文件中 while ((length = is.read(buffer)) > 0) { os.write(buffer, 0, length); } System.out.println("上传文件名"+myFileFileName); System.out.println("上传文件类型"+myFileContentType); //关闭输入流 is.close(); //关闭输出流 os.close(); //设置session 存储文件目录 session.setAttribute("filePath", uploadPath+"/"+myFileFileName); /*try { // 获取原始文件名 String originalName = this.getMyFileFileName(); // 获取文件的后缀 //String suffix = originalName.substring(originalName.lastIndexOf(".") + 1); String path=OSSUtils.uploadImage(is, "yxServer/" + StringUtils.replace(originalName, "." + suffix, "") + UUID.randomUUID().toString().replaceAll("-", "").toString() + "." + suffix, ""); String url = OSSUtils.uploadImage(FileUtils.openInputStream(new File(uploadPath+"/"+originalName)),"yxServer/"+originalName, ""); System.out.println(url); } catch (Exception e) { e.printStackTrace(); }*/ return SUCCESS; } }
3.struts配置
<action name="BannerAction" class="com.action.BannerAction"> <result name="success" type="chain">MachineDeliverAction</result> </action>
4.选择权限，分配机器

3.绑定action
