之前给大家介绍了sso的相关知识点和集成方案，考虑到每个系统所属行业的不同，这边针对于不同行业做了一些统一的sso单点登录界面模板，使用fileupload多文件上传+OSS阿里云存储方案。（企业架构源码可以加求球：叁五三陆二肆柒二伍玖）
1. 阿里云oss存储Utils（企业架构源码可以加求球：叁五三陆二肆柒二伍玖）
public class AliyunUtils { private static AliyunUtils aliyun; private AliyunUtils() { } public static synchronized AliyunUtils getInstance(){ if(aliyun==null){ aliyun=new AliyunUtils(); } return aliyun; } /** * 上传byte数组 * @param fileByte * @param fileKey */ public void uploadByte(byte[] fileByte, String fileKey){ // 创建OSSClient实例 OSSClient ossClient = new OSSClient(CloudConstant.ENDPOINT, CloudConstant.ACCESSKEYID, CloudConstant.ACCESSKEYSECRET); // 上传byte数组 ossClient.putObject(CloudConstant.BUCKET, fileKey, new ByteArrayInputStream(fileByte)); // 关闭client ossClient.shutdown(); } /** * 上传文件流 * @param inputStream * @param fileKey */ public void uploadInputStream(InputStream inputStream, String fileKey){ // 创建OSSClient实例 OSSClient ossClient = new OSSClient(CloudConstant.ENDPOINT, CloudConstant.ACCESSKEYID, CloudConstant.ACCESSKEYSECRET); // 上传文件流 ossClient.putObject(CloudConstant.BUCKET, fileKey, inputStream); // 关闭client ossClient.shutdown(); } /** * 删除文件 * @param fileKey */ public void deleteFile(String fileKey){ // 创建OSSClient实例 OSSClient ossClient = new OSSClient(CloudConstant.ENDPOINT, CloudConstant.ACCESSKEYID, CloudConstant.ACCESSKEYSECRET); // 删除文件 ossClient.deleteObject(CloudConstant.BUCKET, fileKey); // 关闭client ossClient.shutdown(); } //base64字符串转化成图片 @SuppressWarnings("restriction") public static byte[] BASE64DecoderStringToByte(String imgStr) { //对字节数组字符串进行Base64解码并生成图片 if (imgStr == null) //图像数据为空 return null; sun.misc.BASE64Decoder decoder = new sun.misc.BASE64Decoder(); try { //Base64解码 byte[] b = decoder.decodeBuffer(imgStr); return b; } catch (Exception e){ return null; } } public static void main(String[] args) { //AliyunUtils.getInstance().uploadByte(BASE64DecoderStringToByte(base64), "aabb.jpg"); } }
2. 阿里云配置常量类（可以配置到数据库或者properties，后面会更新配置方式）
public class CloudConstant { /****************阿里云OSS上传文件配置****************/ public static final String ENDPOINT = "http://oss-cn-shanghai.aliyuncs.com"; //外网访问域名 //public static final String ENDPOINT = "http://oss-cn-shanghai-internal.aliyuncs.com"; //内网访问域名 public static final String ACCESSKEYID = "12345678qwertyu; //标识用户 public static final String ACCESSKEYSECRET = "1234567890WERTYUIO"; //加密签名字符 public static final String BUCKET = "huiyi-bucket"; //存储空间 /****************背景文件路径配置****************/ public static final String BACK_IMG_INFO_PATH = "sso/backageImg/"; }
3. sso templateController类
public String save(SsoTemplate ssoTemplate, Model model, RedirectAttributes redirectAttributes, @RequestParam(value = "file", required = false) MultipartFile file) { if (!beanValidator(model, ssoTemplate)) { return form(ssoTemplate, model); } String fileName = String.valueOf(new Date().getTime()); String staff = ""; String fileKey = ""; // 上传文件 if (file.getSize() != 0) { staff = FilenameUtils.getExtension(file.getOriginalFilename()); fileKey = CloudConstant.BACK_IMG_INFO_PATH + fileName + "." + staff; // 删除OSS文件 AliyunUtils.getInstance().deleteFile(fileKey); // 上传文件至阿里云OSS try { AliyunUtils.getInstance().uploadInputStream(file.getInputStream(), fileKey); ssoTemplate.setImg(fileKey); } catch (IOException e) { e.printStackTrace(); } } ssoTemplateService.save(ssoTemplate); addMessage(redirectAttributes, "保存模板成功"); return "redirect:" + Global.getAdminPath() + "/sso/ssoTemplate"; }
4. 界面显示效果
