upload.jsp 这个页面选择提交文件，提交到uploadImage.action
<%@ page language="java" contentType="text/html; charset=utf-8"
pageEncoding="utf-8"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8">
<title>Insert title here</title>
</head>
<body>
<form action="uploadImage.action" enctype="multipart/form-data" method="post">
please select the file:<input type="file" name="upload">
<input type="submit" value="上传文件">
</form>
</body>
</html>FileUploadAction.java 将传来的file进行处理
package action;
import java.io.File;
import java.io.FileInputStream;
import java.io.FileOutputStream;
import org.apache.commons.io.IOUtils;
import org.apache.struts2.ServletActionContext;
import com.opensymphony.xwork2.ActionSupport;
public class FileUploadAction extends ActionSupport{
private File upload;
private String uploadFileName;
private String uploadContentType;
public File getUpload() {
return upload;
}
public void setUpload(File upload) {
this.upload = upload;
}
public String getUploadFileName() {
return uploadFileName;
}
public void setUploadFileName(String uploadFileName) {
this.uploadFileName = uploadFileName;
}
public String getUploadContentType() {
return uploadContentType;
}
public void setUploadContentType(String uploadContentType) {
this.uploadContentType = uploadContentType;
}
public String execute(){
System.out.println(upload);
System.out.println(uploadContentType);
System.out.println(uploadFileName);
String savePath = ServletActionContext.getServletContext().getRealPath("/upload/"+this.uploadFileName);
System.out.println(savePath);
try{
FileInputStream fis = new FileInputStream(upload);
FileOutputStream fos = new FileOutputStream(savePath);
IOUtils.copy(fis, fos);
fos.flush();
fos.close();
fis.close();
}catch(Exception e){
e.printStackTrace();
}
return "success";
}
}uploadFileName和uploadContentType，这两个属性分别用于封装上传文件的文件名、上传文件的文件类型
Struts.xml配置
<action name="uploadImage" class="action.FileUploadAction"> <result name="success">uploadSuccess.jsp</result> <result name="input">uploadError.jsp</result> </action>
