用什么网站做一手房最好/网站关键词排名seo

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。

1. 阿里云oss存储Utils

Java代码

public class AliyunUtils {  ```javaprivate 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）

Java代码

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Java代码 ```java
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
