对应后台接收类：
package com.model.dto;
import java.io.File;
public class FileModel {
private String title = null;
private File process = null;
private String uploadContentType = null;
private String savePath = null;
public String getUploadContentType() {
return uploadContentType;
}
public void setUploadContentType(String uploadContentType) {
this.uploadContentType = uploadContentType;
}
public String getTitle() {
return title;
}
public void setTitle(String title) {
this.title = title;
}
public File getProcess() {
return process;
}
public void setProcess(File process) {
this.process = process;
}
public String getSavePath() {
return savePath;
}
public void setSavePath(String savePath) {
this.savePath = savePath;
}
}
处理的Action:
package com.action;
import java.io.File;
import java.io.FileInputStream;
import java.io.FileNotFoundException;
import java.io.FileOutputStream;
import java.io.IOException;
import org.apache.struts2.ServletActionContext;
import com.model.dto.FileModel;
import com.opensymphony.xwork2.ActionSupport;
import com.opensymphony.xwork2.ModelDriven;
public class FileAction extends ActionSupport implements ModelDriven<FileModel>{
private FileModel fileModel = new FileModel();
public String execute(){
System.out.println(fileModel.getTitle());
System.out.println(fileModel.getSavePath());
System.out.println(fileModel.getProcess());
try {
File f = new File(ServletActionContext.getRequest().getRealPath(fileModel.getSavePath()));
if(!f.exists()){
f.mkdirs();
}
FileOutputStream fos = new FileOutputStream(f+"/1.txt");
FileInputStream fis = new FileInputStream(fileModel.getProcess());
byte [] b = new byte[1024];
while((fis.read(b))!=-1){
fos.write(b, 0, b.length);
}
fos.close();
fis.close();
} catch (FileNotFoundException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
return SUCCESS;
}
public FileModel getModel() {
return fileModel;
}
}
