struts的文件上传之后

1.struts是自带的文件上传拦截器

于是配置上有些变化

<action name="upload" class="com.actions.uploadAction" > <interceptor-ref name="fileUpload">   <param name="allowedTypes">image/jpeg,image/bmp</param> </interceptor-ref> <interceptor-ref name="default"></interceptor-ref> <param name="savePath">/uploads</param>    <result name="suc">/suc.jsp</result></action>

然后就是 jsp页面的 form 需要加特殊的属性

   <form action="upload.action" method="post" enctype="multipart/form-data">      <input name="title" type="text" />       <input name="upload" type="file" id="upload" onchange="showUpload()" />      <input  type="submit" value="体检" /><br/>    <img style="display:none;" id="uploading"/>   </form>

最后就是 action处理页面

package com.actions;import java.io.File;import java.io.IOException;import org.apache.commons.io.FileUtils;import org.apache.struts2.ServletActionContext;import com.opensymphony.xwork2.ActionSupport;public class uploadAction extends ActionSupport{private String title;private File  upload;private String  uploadName;private String uploadContentType;////////////////////////////////////////////////////////////////////////////////        // 这是自己 配置private String savePath;public String execute(){try {FileUtils.copyDirectory(upload,new File(this.getSavePath()));return "suc";} catch (IOException e) {e.printStackTrace();}return null;} public String getSavePath() {return ServletActionContext.getRequest().getRealPath(savePath)+"\\"+this.getUploadName();}public void setSavePath(String savePath) {this.savePath = savePath;}}
