webwork文件上传总结

        webwork文件上传,用百度,狗狗,一搜就可以搜到很多相关的贴子,这其中不少贴子可称经典,可以载入史册.

在公司闲得没事做,就总结一下webwork的上传全过程.

        首先我们得写一个webwork的配置文件(首先你得保证你这个工程加入了webwork)

        代码如下:

    

       

 

 

   
             
          /casePigeonholeList.action
  
       
  

 

      第二,就得开发Action,简单的说就是开发java类.

      代码如下:

    

 

package com.marty;

import java.io.File;
import java.io.FileInputStream;
import java.io.FileOutputStream;
import javax.servlet.http.HttpServletRequest;

import service.CasePigeonholeService;

import com.opensymphony.webwork.interceptor.ServletRequestAware;

public class CasePigeonholeManager  implements ServletRequestAware{

 

 private CasePigeonholeService casePigeonholeService;

 private domain.CasePigeonhole casePigeonhole;
 private File[] cattas;//文件
 private String[] cattasFileName;//文件名
 private String[] cattasContentType; //内容类型
  HttpServletRequest request=null;

 
 public String execute()throws Exception{
    return SUCCESS;
 }

 
 
 public String casePigeonholeAdd()throws Exception{
  casePigeonholeService.saveCasePigeonhole(casePigeonhole,cattas,cattasFileName,cattasContentType
    ,request);
  return SUCCESS;
 }
 
 
 @Override
 public int getModuleRightId() {
  // TODO Auto-generated method stub
  return 0;
 }

 public CasePigeonholeService getCasePigeonholeService() {
  return casePigeonholeService;
 }

 public void setCasePigeonholeService(CasePigeonholeService casePigeonholeService) {
  this.casePigeonholeService = casePigeonholeService;
 }

  public domain.CasePigeonhole getCasePigeonhole() {
  return casePigeonhole;
 }

 public void setCasePigeonhole(domain.CasePigeonhole casePigeonhole) {
  this.casePigeonhole = casePigeonhole;
 }

  public File[] getCattas() {
  return cattas;
 }

 public void setCattas(File[] cattas) {
  this.cattas = cattas;
 }

 public String[] getCattasContentType() {
  return cattasContentType;
 }

 public void setCattasContentType(String[] cattasContentType) {
  this.cattasContentType = cattasContentType;
 }

 public String[] getCattasFileName() {
  return cattasFileName;
 }

 public void setCattasFileName(String[] cattasFileName) {
  this.cattasFileName = cattasFileName;
 }

 public void setServletRequest(HttpServletRequest request) {
  this.request=request;
 
 }
}

 

 

第三.开发SERVICE.

 

package service.impl;

import java.io.File;
import java.io.FileInputStream;
import java.io.FileNotFoundException;
import java.io.FileOutputStream;
import java.io.IOException;
import java.util.Properties;

import javax.servlet.http.HttpServletRequest;

import service.CasePigeonholeService;

import com.opensymphony.webwork.interceptor.ServletRequestAware;

import common.GetProperty;

import domain.CaseDocument;
import domain.CaseInfo;
import domain.CasePigeonhole;

public class CasePigeonholeServiceImpl  implements
  CasePigeonholeService{

 

 public void saveCasePigeonhole(CasePigeonhole casePigeonhole,
   File[] cattas, String[] cattasFileName, String[] cattasContentType,HttpServletRequest request)throws Exception{
    for(int i=0;i   insertFileAtta(cph.getCase_info_id(),cattas[i],cattasFileName[i],cattasContentType[i],request);
  }
  }

 }
 
 public void insertFileAtta(String caseID,
   File atta, String attaFileName, String attaContentType,HttpServletRequest request) throws Exception {
  //保存附件
  CaseDocument caseDoc=new CaseDocument();
  String propName ="caseUpload";
     String value = "";
    
     //Properties对象读取*.properties中的文件
     Properties prop = new Properties();
     try{
        // String path = System.getProperty("user.dir");      //获得工程的路径名
       String path=request.getSession().getServletContext().getRealPath("//WEB-INF//");
         logger.info("path:"+path);
         prop.load(new FileInputStream(path + File.separator +"uploadPath.properties"));
         //从工程的路径中装载propeties文件
         value = prop.getProperty(propName);    //获取参数值
     }catch(FileNotFoundException fnfe){
         logger.info("file /"uploadPath.properties/" not found");
         fnfe.printStackTrace();
     }catch(IOException ioe){
      logger.info("io exception");
         ioe.printStackTrace();
     }
 
  //文件上传处理
  String fileurl =value;//获取上传路径
  logger.info("fileurl:"+fileurl);
  FileTools.createDir(fileurl);

  String tmp = attaFileName.substring(attaFileName.lastIndexOf(".") + 1);
 
  String tmpfilename = String.valueOf(System.currentTimeMillis())
    + String.valueOf(Math.round(Math.random() * 1000D)) + "." + tmp;
  caseDoc.setCase_file_name(tmpfilename);
  caseDoc.setUrl_content(fileurl);
  caseDoc.setCase_info_id(caseID);
 
  FileOutputStream fos = new FileOutputStream(fileurl + tmpfilename);
  FileInputStream is = new FileInputStream(atta);
  FileTools.copyStream(is, fos);
  is.close();
  fos.close();

   insert(caseDoc);
 

 
 }

 

}

看properties配置文件.

 

###when cvs a project please change
###the directory or create a directory
caseUpload=D:/zhudaoqin/workspace/xzzf-0822B/Webroot/upload/

 

 

 

好了.
