webwork 文件上传

--1：先看属性

 

private String[] upfileFileName;
	private String[] upfileContentType;
	
	
	
	public String[] getUpfileContentType() {
		return upfileContentType;
	}

	public void setUpfileContentType(String[] upfileContentType) {
		this.upfileContentType = upfileContentType;
	}

	public String[] getUpfileFileName() {
		return upfileFileName;
	}

	public void setUpfileFileName(String[] upfileFileName) {
		this.upfileFileName = upfileFileName;
	}

	private String path = "/titlepic";

 2：在看代码

String upPath = ServletActionContext.getServletContext().getRealPath(path) + File.separator;    		
    		//字符串截取。
			String[] existName = infoTpicnew.getInfoPicname().split(",");
			//字符串拼接。
			String objName = "";
			
    		for(int i=0;i<upfileFileName.length;i++){
    			String fName = upfileFileName[i];
    			String type = upfileContentType[i];
    			//删除源对应位置的图片。
    			if(i<existName.length&&existName[i].length() > 0 && !fName.equals("")){
        			FileTools.delFile(upPath + existName[i]);
        		}
    			//添加新图片
        		if(!fName.equals("")){
        			int index = fName.lastIndexOf(".");  	
        			String newFileName = System.currentTimeMillis()+ i + fName.substring(index, fName.length());
        			
        			File saveFile = new File(upPath);
        			File downloandFile = new File(upPath + newFileName);	
        			boolean bFile   = saveFile.exists();
        		    if( bFile == false )
        		    	bFile = saveFile.mkdirs();
        			
        			
        			upfile[i].renameTo(downloandFile);
        			objName += newFileName;
        			
        			//判断是否是最后一张,不是则加分隔符。
        			if((i+1)<upfileFileName.length){
        				objName += ",";
        			}
        			
        		}
    		}

 感觉就一个renameto就搞定上传了。。是不是太崩溃了。。。
