java 上传文件到oss(阿里云)

做这个功能之前我们需要导入阿里云OSS官方提供的工具包
aliyun-sdk-oss-2.5.0.jar 这个文件 如果有最新版的话就下载最新版

aliyun.upload.AliyunConfig

package aliyun.upload;public final class AliyunConfig {    //你的oss所在域，要加http://   不明白可以对照你的文件引用地址    public static String endpoint = "http://oss-cn-shenzhen.aliyuncs.com";    //密匙keyId 可以在阿里云获取到    public static String accessKeyId = "xxxxxxx";    //密匙keySecret 可以在阿里云获取到    public static String accessKeySecret = "";    //你的bucketName 名称   即是你的OSS对象名称  不明白查oss开发文档专业术语     public static String bucketName = "";}

aliyun.upload.IAliyunUpload

package aliyun.upload;public interface IAliyunUpload {    /**     * @param     * String filePathName 本地图片路径（D:/xxxx/xxxx....../xx/xx.jgp|xx.png|..）     * String savePathName 将要保存到OSS上的路径地址     * */    public String uploadFile(String filePathName,String savePathName);}
