Spring mvc+oss存储+fileupload多文件上传实现SSO单点登录模板管理

发布于

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

代码语言：javascript
复制
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）（企业架构源码可以加求球：三五三六二四七二五九）

代码语言：javascript
复制
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

代码语言：javascript
复制
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";  
}  </code></pre></div></div><p> 4. 界面显示效果</p><figure class=""><div class="rno-markdown-img-url" style="text-align:center"><div class="rno-markdown-img-url-inner" style="width:100%"><div style="width:100%"><img src="https://cdn.static.attains.cn/app/developer-bbs/upload/1722842405252361243.png" /></div></div></div></figure><figure class=""><div class="rno-markdown-img-url" style="text-align:center"><div class="rno-markdown-img-url-inner" style="width:100%"><div style="width:100%"><img src="https://cdn.static.attains.cn/app/developer-bbs/upload/1722842405564159958.png" /></div></div></div></figure><figure class=""><div class="rno-markdown-img-url" style="text-align:center"><div class="rno-markdown-img-url-inner" style="width:100%"><div style="width:100%"><img src="https://cdn.static.attains.cn/app/developer-bbs/upload/1722842406142983797.png" /></div></div></div></figure><figure class=""><div class="rno-markdown-img-url" style="text-align:center"><div class="rno-markdown-img-url-inner" style="width:100%"><div style="width:100%"><img src="https://cdn.static.attains.cn/app/developer-bbs/upload/1722842407100420060.png" /></div></div></div></figure>
