一.创建Bucket
二.获取AccessKey密钥
三.参考官方SDK文件编写入门程序
1.复制阿里云OSS依赖粘贴到pom.xml文件里
2. 将上传文件流的Demo测试类复制到test文件里
四.集成OSS运用于项目中
1. 在yml文件配置自定义阿里云OSS信息
2.编写阿里云工具类官方代码改编 3.编写文件上传类接口
一.创建Bucket 二.获取AccessKey密钥 注意保存好你的AccessKey ID
三.参考官方SDK文件编写入门程序 1.复制阿里云OSS依赖粘贴到pom.xml文件里 !--阿里云OSS--dependencygroupIdcom.aliyun.oss/groupIdartifactIdaliyun-sdk-oss/artifactIdversion3.15.1/version/dependency
2. 将上传文件流的Demo测试类复制到test文件里
import com.aliyun.oss.ClientException;
import com.aliyun.oss.OSS;
import com.aliyun.oss.common.auth.*;
import com.aliyun.oss.OSSClientBuilder;
import com.aliyun.oss.OSSException;
import com.aliyun.oss.model.PutObjectRequest;
import com.aliyun.oss.model.PutObjectResult;
import java.io.FileInputStream;
import java.io.InputStream;public class Demo {public static void main(String[] args) throws Exception {// Endpoint以华东1杭州为例其它Region请按实际情况填写。String endpoint https://oss-cn-hangzhou.aliyuncs.com;// 从环境变量中获取访问凭证。运行本代码示例之前请确保已设置环境变量OSS_ACCESS_KEY_ID和OSS_ACCESS_KEY_SECRET。EnvironmentVariableCredentialsProvider credentialsProvider CredentialsProviderFactory.newEnvironmentVariableCredentialsProvider();// 填写Bucket名称例如examplebucket。String bucketName examplebucket;// 填写Object完整路径完整路径中不能包含Bucket名称例如exampledir/exampleobject.txt。String objectName exampledir/exampleobject.txt;// 填写本地文件的完整路径例如D:\\localpath\\examplefile.txt。// 如果未指定本地路径则默认从示例程序所属项目对应本地路径中上传文件流。String filePath D:\\localpath\\examplefile.txt;// 创建OSSClient实例。OSS ossClient new OSSClientBuilder().build(endpoint, credentialsProvider);try {InputStream inputStream new FileInputStream(filePath);// 创建PutObjectRequest对象。PutObjectRequest putObjectRequest new PutObjectRequest(bucketName, objectName, inputStream);// 创建PutObject请求。PutObjectResult result ossClient.putObject(putObjectRequest);} catch (OSSException oe) {System.out.println(Caught an OSSException, which means your request made it to OSS, but was rejected with an error response for some reason.);System.out.println(Error Message: oe.getErrorMessage());System.out.println(Error Code: oe.getErrorCode());System.out.println(Request ID: oe.getRequestId());System.out.println(Host ID: oe.getHostId());} catch (ClientException ce) {System.out.println(Caught an ClientException, which means the client encountered a serious internal problem while trying to communicate with OSS, such as not being able to access the network.);System.out.println(Error Message: ce.getMessage());} finally {if (ossClient ! null) {ossClient.shutdown();}}}
}
注意需配置环境变量然后修改为自己的配置
①添加系统环境变量即你的AccesskKyId和accessKeySecret ②修改Demo里的endpoint、bucketName、objectName和filePath 只需修改这四个用于测试运行Demo查看OSS上传成功 四.集成OSS运用于项目中
1. 在yml文件配置自定义阿里云OSS信息
①在AliOSSProperties类中先使用ConfigurationProperties自动注入到yml中
import lombok.Data;
import org.springframework.boot.context.properties.ConfigurationProperties;
import org.springframework.stereotype.Component;Data
Component
ConfigurationProperties(prefix aliyun.oss)
public class AliOSSProperties {private String endpoint;private String accessKeyId;private String accessKeySecret;private String bucketName;
}
②然后在yml文件中配置阿里云OSS 2.编写阿里云工具类官方代码改编
import com.aliyun.oss.OSS;
import com.aliyun.oss.OSSClientBuilder;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.boot.context.properties.ConfigurationProperties;
import org.springframework.stereotype.Component;
import org.springframework.web.multipart.MultipartFile;
import java.io.*;
import java.util.UUID;/*** 阿里云 OSS 工具类*/
Component
ConfigurationProperties
public class AliOSSUtils {Autowiredprivate AliOSSProperties aliOSSProperties;/*** 实现上传图片到OSS*/public String upload(MultipartFile file) throws IOException {//获取阿里云OSS参数String endpoint aliOSSProperties.getEndpoint();String accessKeyId aliOSSProperties.getAccessKeyId();String accessKeySecret aliOSSProperties.getAccessKeySecret();String bucketName aliOSSProperties.getBucketName();// 获取上传的文件的输入流InputStream inputStream file.getInputStream();// 避免文件覆盖String originalFilename file.getOriginalFilename();String fileName UUID.randomUUID().toString() originalFilename.substring(originalFilename.lastIndexOf(.));//上传文件到 OSSOSS ossClient new OSSClientBuilder().build(endpoint, accessKeyId, accessKeySecret);ossClient.putObject(bucketName, fileName, inputStream);//文件访问路径String url endpoint.split(//)[0] // bucketName . endpoint.split(//)[1] / fileName;// 关闭ossClientossClient.shutdown();return url;// 把上传到oss的路径返回}} 3.编写文件上传类接口
import com.itheima.pojo.Result;
import com.itheima.utils.AliOSSUtils;
import lombok.extern.slf4j.Slf4j;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.PostMapping;
import org.springframework.web.bind.annotation.RestController;
import org.springframework.web.multipart.MultipartFile;import java.io.IOException;Slf4j
RestController
public class UploadController {//注入阿里云工具类Autowiredprivate AliOSSUtils aliOSSUtils;PostMapping(/upload)public Result upload(MultipartFile image) throws IOException {log.info(文件上传文件名{}, image.getOriginalFilename());//调用阿里云OSS工具类进行文件上传String url aliOSSUtils.upload(image);log.info(文件上传完成文件访问的url{}, url);return Result.success(url);}
}
至此。后端上传文件至阿里云的代码完成
