SSH文件上传功能

1.在action中定义三个属性及set方法

	/**
	 * 文件上传提供 的三个属性
	 * 三个属性的前缀名"upload"要与页面中上传项的name一致
	 */
	private String uploadFileName;//文件名称
	private File upload;			//上传文件
	private String uploadContentType;//文件类型
	
	public void setUploadFileName(String uploadFileName) {
		this.uploadFileName = uploadFileName;
	}
	public void setUpload(File upload) {
		this.upload = upload;
	}
	public void setUploadContentType(String uploadContentType) {
		this.uploadContentType = uploadContentType;
	}

2.编写 Action

	/**
	 * 保存客户的方法：save
	 * @throws IOException 
	 */
	public String save() throws IOException {
		//文件上传
		if(upload != null){
			//设置文件上传路径
			String path= "d:/upload";
			//设置随机文件名
			String uuidFileName = UploadUtils.getUUIDName(uploadFileName);
			//设置目录分离
			String realPath = UploadUtils.getPath(uuidFileName);
			//设置文件路径
			String url = path+realPath;
			File file = new File(url);
			if(!file.exists()){
				file.mkdirs();
			}
			//文件上传
			File destFile = new File(url+"/"+uuidFileName);
			FileUtils.copyFile(upload, destFile);
			customer.setCust_image(url+"/"+uuidFileName);
		}
		customerService.save(customer);
		return "saveSuccess";
	}

3.配置文件上传拦截器

		<interceptor-ref name="defaultStack">
				<param name="fileUpload.maximumSize">2097152</param>
				<param name="fileUpload.allowedExtensions">.jpg,png</param>
		</interceptor-ref>
