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>
成功失败界面随便写一个就行了，不贴了。
