5.uploadAction.java

package com.luodada.trans.soa.busi.web;

import java.io.File;
import java.io.FileInputStream;
import java.io.FileNotFoundException;
import java.io.FileOutputStream;
import java.io.IOException;
import java.text.DateFormat;
import java.text.SimpleDateFormat;
import java.util.Date;
import java.util.ResourceBundle;

import com.opensymphony.xwork.ActionSupport;

public class UploadAction extends ActionSupport {
	
	private String fileFileName; 
	private File file; 
	
	public String uploadFile() { 
		upload();
		return "succ"; 
	} 
	
	// 上传文件 
	private void upload() { 
		if(file!=null) { 
			FileOutputStream outputStream; 
				try{ 
					ResourceBundle rb = ResourceBundle.getBundle("config");
					String fileDir = rb.getString("saveDir") + File.separator;
					Date date = new Date();
					DateFormat df = new SimpleDateFormat("yyyyMMddHHmmss");
					String time = df.format(date);
					fileFileName = time + "_" + fileFileName;
					String filePath = fileDir + fileFileName;
					try {
						// 创建目录 
						File f = new File(fileDir);   
						f.mkdirs(); 
					} catch (Exception ex) {
						ex.printStackTrace();
					}
					outputStream = new FileOutputStream(filePath); 
					FileInputStream fileIn = new FileInputStream(file); 
					byte[] buffer = new byte[1024]; 
					int len; 
					while ((len = fileIn.read(buffer)) > 0) { 
						outputStream.write(buffer, 0, len); 
					} 
					fileIn.close(); 
					outputStream.close();
				} catch (FileNotFoundException ex) { 
					ex.printStackTrace(); 
				} catch (IOException ex) {
					ex.printStackTrace();
				}
				System.out.println("uploadfile name="+fileFileName); 
		} else {
			System.out.println("file is null!"); 
		}
	}

	public File getFile() { 
		return file; 
	} 

	public void setFile(File file) { 
		this.file = file; 
	} 

	public String getFileFileName() { 
		return fileFileName; 
	} 

	public void setFileFileName(String fileName) { 
		this.fileFileName = fileName; 
	}
}

 

6.xwork-config.xml的配置

<!-- 上传文件 -->
<action name="upload" class="uploadAction" method="uploadFile">
       <interceptor-ref name="fileUpload" />
       <interceptor-ref name="defaultStack" />
       <result name="succ">/upload/uploadFileSucc.jsp</result>
</action>

 

 

注意事项：

1.<form>表单中要加上属性  enctype="multipart/form-data"

2.xwork-config.xml中要配置<interceptor-ref name="fileUpload" />和<interceptor-ref name="defaultStack" />

3.xwork-config.xml中要添加method="**"的属性

4.webwork上传文件只是暂时存放在一个文件夹等待action里处理，处理完毕就会删除临时文件，所以在action里一定要自行对文件进行处理，不能指望它自动保存，因此在 upload()函数里保存了一次。

5.webwork.multipart.parser是设置处理上传的类的，有jakarta、cos、pell 三种设置， jakarta是默认的设置；注意设置了相应的类要把相应的jar放进来(jakarta支持多文件上传，cos和pell不支持)；
