。。。。

Action的代码是

package xhy.shjc;
import java.io.File;
import java.io.IOException;
import org.apache.commons.io.FileUtils;

public class UserAction{
//public User user;
private File uploadFile;
private String fileName;

public String add(){
try {
FileUtils.copyFile(uploadFile, new File("g:/Temp/"+fileName));
} catch (IOException e) {
e.printStackTrace();
}

System.out.println(fileName);
return "success";
}

public File getUploadFile() {
return uploadFile;
}
public void setUploadFile(File uploadFile) {
this.uploadFile = uploadFile;
}
public void setUploadFileFileName(String fName) {
fileName = fName;
}
public void setUploadFileContentType(String ct){
System.out.println(ct);
}

struts.xml:
<action name="test" class="xhy.shjc.UserAction">
      
            <result name="success">
                /success.jsp
            </result>
        </action>

jsp:
<form action="test" method="post" enctype="multipart/formdata">
<input type="hidden" name="method:add">
<input type="file" name="uploadFile">
<input type="submit" name="submit" value="上传文件">
<s:debug></s:debug>
  </form>
[最优解释]
enctype="multipart/formdata"错了应该是enctype="multipart/form-data

在struts.xml中对应的action配置
<interceptor-ref name="fileUpload">
  <param name="allowedTypes">text/html,text/plain</param>
             <param name="maximumSize">2048000</param>
       </interceptor-ref>
    <interceptor-ref name="defaultStack"/>
[其他解释]
你的方法是setUploadFile(File uploadFile)而你真真调用的是setUploadFile(String ..)方法，所以报找不到方法错！
