阿里云上传文件1（未分模块）
1、pom文件加入依赖
<!--阿里云 OSS 依赖-->
<dependency><groupId>com.aliyun.oss</groupId><artifactId>aliyun-sdk-oss</artifactId><version>3.15.1</version>
</dependency>
<dependency><groupId>javax.xml.bind</groupId><artifactId>jaxb-api</artifactId><version>2.3.1</version>
</dependency>
<dependency><groupId>javax.activation</groupId><artifactId>activation</artifactId><version>1.1.1</version>
</dependency>
<!-- no more than 2.3.3-->
<dependency><groupId>org.glassfish.jaxb</groupId><artifactId>jaxb-runtime</artifactId><version>2.3.3</version>
</dependency><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-configuration-processor</artifactId>
</dependency>
<dependency><groupId>org.jetbrains</groupId><artifactId>annotations</artifactId><version>RELEASE</version><scope>compile</scope>
</dependency>2、配置yam
这个写自己的身份id-密钥-桶名
# 阿里云相关配置
aliyun:oss:# 外网访问路径endpoint: http://oss-cn-beijing.aliyuncs.com# 身份idaccessKeyId: LTAI5tS4GcnjVmnp# 密钥accessKeySecret: s2ioVYtO5bqhwluSJMvkx# 桶名bucketName: zsh333、引入工具类
package com.zsh.springboot_webtwo.utils;import com.aliyun.oss.OSS;
import com.aliyun.oss.OSSClientBuilder;
import lombok.Data;
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.IOException;
import java.io.InputStream;
import java.util.UUID;@ConfigurationProperties(prefix = "aliyun.oss")
@Data
@Component
public class AliOSSUtils {// @Value("${aliyun.oss.endpoint}")private String endpoint; // 外网访问路径
// @Value("${aliyun.oss.accessKeyId}")private String accessKeyId; // 身份id
// @Value("${aliyun.oss.accessKeySecret}")private String accessKeySecret; // 密钥
// @Value("${aliyun.oss.bucketName}")private String bucketName; // 桶名/*** 实现上传图片到OSS*/public String upload(@org.jetbrains.annotations.NotNull MultipartFile multipartFile) throws IOException {// 获取上传的文件的输入流InputStream inputStream = multipartFile.getInputStream();// 避免文件覆盖String originalFilename = multipartFile.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}
}4、Controller 文件上传
package com.zsh.springboot_webtwo.controller;import com.itheima.springboot_webtwo.utils.AliOSSUtils;
import com.itheima.springboot_webtwo.utils.Result;
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;@RestController
public class UploadController {@Autowiredprivate AliOSSUtils aliOSSUtils;@PostMapping("/upload")public Result upload(MultipartFile image) throws IOException {String url = aliOSSUtils.upload(image);return Result.success(url);}
}阿里云上传文件2（分模块）
1、定义OSS相关配置
在zsh-server模块
application-dev.yml
zsh:alioss:endpoint: oss-cn-hangzhou.aliyuncs.comaccess-key-id: LTAI5tPeFLzsPPT8gG3LPW64access-key-secret: U6k1brOZ8gaOIXv3nXbulGTUzy6Pd7bucket-name: zsh-take-outapplication.yml
spring:profiles:active: dev #设置环境
zsh:alioss:endpoint: oss-cn-beijing.aliyuncs.comaccess-key-id: LTAIGcnmnpaccess-key-secret: s2iohwOUMvkxbucket-name: zsh332、读取OSS配置
在zsh-common模块中，已定义
package com.zsh.properties;import lombok.Data;
import org.springframework.boot.context.properties.ConfigurationProperties;
import org.springframework.stereotype.Component;@Component
@ConfigurationProperties(prefix = "zsh.alioss")
@Data
public class AliOssProperties {private String endpoint;private String accessKeyId;private String accessKeySecret;private String bucketName;}3、生成OSS工具类对象
在zsh-server模块
package com.zsh.config;import com.zsh.properties.AliOssProperties;
import com.zsh.utils.AliOssUtil;
import lombok.extern.slf4j.Slf4j;
import org.springframework.boot.autoconfigure.condition.ConditionalOnMissingBean;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;/*** 配置类，用于创建AliOssUtil对象*/
@Configuration
@Slf4j
public class OssConfiguration {@Bean@ConditionalOnMissingBeanpublic AliOssUtil aliOssUtil(AliOssProperties aliOssProperties){log.info("开始创建阿里云文件上传工具类对象：{}",aliOssProperties);return new AliOssUtil(aliOssProperties.getEndpoint(),aliOssProperties.getAccessKeyId(),aliOssProperties.getAccessKeySecret(),aliOssProperties.getBucketName());}
}AliOssUtil.java在zsh-common模块中定义
package com.zsh.utils;import com.aliyun.oss.ClientException;
import com.aliyun.oss.OSS;
import com.aliyun.oss.OSSClientBuilder;
import com.aliyun.oss.OSSException;
import lombok.AllArgsConstructor;
import lombok.Data;
import lombok.extern.slf4j.Slf4j;
import java.io.ByteArrayInputStream;@Data
@AllArgsConstructor
@Slf4j
public class AliOssUtil {private String endpoint;private String accessKeyId;private String accessKeySecret;private String bucketName;/*** 文件上传** @param bytes* @param objectName* @return*/public String upload(byte[] bytes, String objectName) {// 创建OSSClient实例。OSS ossClient = new OSSClientBuilder().build(endpoint, accessKeyId, accessKeySecret);try {// 创建PutObject请求。ossClient.putObject(bucketName, objectName, new ByteArrayInputStream(bytes));} 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();}}//文件访问路径规则 https://BucketName.Endpoint/ObjectNameStringBuilder stringBuilder = new StringBuilder("https://");stringBuilder.append(bucketName).append(".").append(endpoint).append("/").append(objectName);log.info("文件上传到:{}", stringBuilder.toString());return stringBuilder.toString();}
}4、定义文件上传接口
在zsh-server模块中定义接口
package com.zsh.controller.admin;import com.zsh.constant.MessageConstant;
import com.zsh.result.Result;
import com.zsh.utils.AliOssUtil;
import io.swagger.annotations.Api;
import io.swagger.annotations.ApiOperation;
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.RequestMapping;
import org.springframework.web.bind.annotation.RestController;
import org.springframework.web.multipart.MultipartFile;import java.io.IOException;
import java.util.UUID;/*** 通用接口*/
@RestController
@RequestMapping("/admin/common")
@Api(tags = "通用接口")
@Slf4j
public class CommonController {@Autowiredprivate AliOssUtil aliOssUtil;/*** 文件上传* @param file* @return*/@PostMapping("/upload")@ApiOperation("文件上传")public Result<String> upload(MultipartFile file){log.info("文件上传：{}",file);try {//原始文件名String originalFilename = file.getOriginalFilename();//截取原始文件名的后缀 dfdfdf.pngString extension = originalFilename.substring(originalFilename.lastIndexOf("."));//构造新文件名称String objectName = UUID.randomUUID().toString() + extension;//文件的请求路径String filePath = aliOssUtil.upload(file.getBytes(), objectName);return Result.success(filePath);} catch (IOException e) {log.error("文件上传失败：{}", e);}return Result.error(MessageConstant.UPLOAD_FAILED);}
}
