七牛云后台上传图片+springboot

1. 搭建SpringBoot框架

2. pom.xml 引入依赖

   <!-- 七牛云上传图片 -->
	    <dependency>
			  <groupId>com.qiniu</groupId>
			  <artifactId>qiniu-java-sdk</artifactId>
			  <version>[7.2.0, 7.2.99]</version>
		</dependency>
		   <!-- 七牛云前台上传图片 需要引入SDK-->
	  <dependency>
	      <groupId>com.qiniu</groupId>
	      <artifactId>qiniu-java-sdk</artifactId>
	      <version>7.2.6</version>
	      <scope>compile</scope>
	    </dependency>
	    <dependency>
	      <groupId>com.squareup.okhttp3</groupId>
	      <artifactId>okhttp</artifactId>
	      <version>3.3.1</version>
	      <scope>compile</scope>
	    </dependency>
	    <dependency>
	      <groupId>com.google.code.gson</groupId>
	      <artifactId>gson</artifactId>
	      <version>2.6.2</version>
	      <scope>compile</scope>
	    </dependency>
	    <dependency>
	      <groupId>com.qiniu</groupId>
	      <artifactId>happy-dns-java</artifactId>
	      <version>0.1.4</version>
	      <scope>compile</scope>
	    </dependency>
		

3.注册七牛云的账户 获取 ak sk
点击 “管理控制台”

然后点击 “个人中心”

然后 点击“密钥管理 ” 就可以看到 ak sk 了

4.申请对象存储空间 存储空间名 下边要用到

5.引入上传后台代码工具类

import java.io.FileInputStream;
import java.io.IOException;

        return auth.uploadToken(bucketname, null, 3600, new StringMap().put("insertOnly", 1));
    }
