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（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
