Struts2 简单的文件上传

包还是那几个包....

 

private static final long serialVersionUID = 1L;
	//struts2把文件域封装成了一个文件File
	private File upload;
	//文件内容类型
	private String uploadContentType;
	//文件名
	private String uploadFileName;
	//保存路径
	private String savePath;
	
	public String execute()throws Exception {
	
	    //savePath = ServletActionContext.getServletContext().getRealPath("/upload");	
		File savefile = new File(new File(this.getSavePath()),this.uploadFileName);
		//判断文件存不存在，不存在就穿件一个
		if(!savefile.getParentFile().exists()){
			savefile.getParentFile().mkdirs();
		}
		//上传
		FileUtils.copyFile(this.upload,savefile);
		return null;
	}

 

jsp   注意  enctype="multipart/form-data"

 

<form action="bai/uploadAction" name="form1" method="post"
			enctype="multipart/form-data">
			<table>
				<tr>
					<td>
						上传:
					</td>
					<td>
						<input type="file" name="upload">
					</td>
				</tr>
				<tr>
					<td colspan="2">
						<input type="submit" value="上传">
					</td>
				</tr>
			</table>

		</form>

 

struts.xml还有可以别的配置的常量

 

<constant name="struts.multipart.saveDir" value="D:/temp" />
	<package name="upload" extends="struts-default" namespace="/bai">
		<action name="uploadAction"
			class="com.btm.uploadAction.UploadAction">
		</action>

	</package>
