springboot整合阿里云oss上传 springboot整合阿里云oss上传的方法示例
╱/.独﹄無㈡oоΟ 人气:0想了解springboot整合阿里云oss上传的方法示例的相关内容吗，╱/.独﹄無㈡oоΟ在本文为您仔细讲解springboot整合阿里云oss上传的相关知识和一些Code实例，欢迎阅读和指正，我们先划重点：springboot整合阿里云oss,springboot,阿里云上传，下面大家一起来学习吧。
OSS申请和配置
1. 注册登录
输入网址：https://www.aliyun.com/product/oss
如果没有账号点击免费注册，然后登录。
2.开通以及配置
点击立即开通
进入管理控制台
第一次使用会出现引导，按引导点击“我知道了”，然后点击创建Bucket。
如果没有存储包或流量包点击购买。
点击确定，返回主页面，出现该页面，点击我知道了
将EndPoint记录下来，方便后期添加到我们项目的配置文件中
创建 AccessKeyID 和 AccessKeySecret
点击创建Access key，第一次需要短信验证，验证成功后弹出
保留Access key 以及 AccessKeySecret 信息
springboot整合使用
1. 进入我们springboot的项目中，导入oss相关依赖
<dependency> <groupId>com.aliyun.oss</groupId> <artifactId>aliyun-sdk-oss</artifactId> <version>2.8.3</version> </dependency>
2. 再配置文件中添加相关信息
oss.aliyun.accessKeyId= # oss.aliyun.accessKeySecret= # oss.aliyun.bucketName= mutest-qcby-oss oss.aliyun.endpoint= # oss.aliyun.pubFlag= false oss.aliyun.expiration= 100 oss.aliyun.sslNmae= #内网使用，不必须
3. 书写获取配置信息的java文件，建立properties包（导入依赖，否则无法识别这个包）
<dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-configuration-processor</artifactId> <optional>true</optional> </dependency>

5. controller 调用样例
我这里使用的是我自己项目封装的 AjaxResult工具类，大家可以使用Map,通过这个方法呢，我们就可以使用oss将图片保存，并且返回前端图片的保存地址(可以访问)。
/**
* 上传
* @param fileupload
* @return
*/
@PostMapping("uploadImg")
@ResponseBody
public AjaxResult uploadImg(MultipartFile fileupload){
if(fileupload != null){
String path = OssFileUtils.uploadSingleFile(fileupload);
return AjaxResult.success(path);
}else {
return AjaxResult.error();
}
}
