　　struts構(gòu)建文件上傳（5）

這是action頁(yè)面,
package tester.business.maitain;

import tclcc.tester.util.Selector;

import org.apache.struts.action.*;
import javax.servlet.http.*;
import java.util.*;
import org.apache.struts.upload.FormFile;
import java.io.*;

public class MaintainAction
extends Action {
public ActionForward execute(ActionMapping actionMapping,
ActionForm actionForm,
HttpServletRequest httpServletRequest,
HttpServletResponse httpServletResponse) {
/**@todo: complete the business logic here, this is just a skeleton.*/
MaintainForm maintainForm = (MaintainForm) actionForm;
TrainPlanDAO trainPDAO = new TrainPlanDAO();
Trainplan trainPlan = new Trainplan();
trainPlan = maintainForm.getTrainPlan();
FormFile theFile = null;
theFile = maintainForm.getTheFile1();
String p_accessory;
p_accessory = theFile.getFileName();
try {
InputStream stream = theFile.getInputStream(); //把文件讀入
String filePath = httpServletRequest.getRealPath("/"); //取當(dāng)前系統(tǒng)路徑
ByteArrayOutputStream baos = new ByteArrayOutputStream();
OutputStream bos = new FileOutputStream(filePath + "http://sub" + "/" +
theFile.getFileName()); //建立一個(gè)上傳文件的輸出流
//System.out.int bytesRead = 0;
byte[] buffer = new byte[8192];
while ( (bytesRead = stream.read(buffer, 0, 8192)) != -1) {
bos.write(buffer, 0, bytesRead); //將文件寫(xiě)入服務(wù)器
}
bos.close();
stream.close();
} catch (Exception e) {
System.err.print(e);
}

try {
trainPlan.setP_accessory(p_accessory);
trainPDAO.addTrainPlan(trainPlan);//調(diào)用數(shù)據(jù)庫(kù)插入方法
System.out.println("sUCcess");

} catch (Exception ex) {
}
httpServletRequest.setAttribute("trainPlain", trainPlan);
return (actionMapping.findForward("trainplanCreated"));
}
}（未完待續(xù)）
