OSS简介，以及阿里云OSS控制台快速入门使用SpringBoot 整合阿里云OSS 存储服务，进行文件上传、下载、查看、删除阿里云OSS文档介绍，以及快速入门使用lombok入门使用以及IDEA lombok插件安装SpringMVC与AJAX前后端分离交互AJAX文件异步上传 Maven依赖 <dependency> <groupId>com.aliyun.oss</groupId> <artifactId>aliyun-sdk-oss</artifactId> <version>2.8.3</version> </dependency> <dependency> <groupId>org.projectlombok</groupId> <artifactId>lombok</artifactId> <version>1.18.4</version> <scope>provided</scope> </dependency> <dependency> <groupId>joda-time</groupId> <artifactId>joda-time</artifactId> <version>2.9.9</version> </dependency> <dependency> <groupId>org.apache.commons</groupId> <artifactId>commons-lang3</artifactId> <version>3.8.1</version> </dependency>

后端实现阿里云OSS配置

aliyun.endpoint=oss-cn-shanghai.aliyuncs.com aliyun.accessKeyId=你的accessKeyId aliyun.accessKeySecret=你的accessKeySecret aliyun.bucketName=gaojun-testbucket aliyun.urlPrefix=http://gaojun-testbucket.oss-cn-shanghai.aliyuncs.com/ spring.servlet.multipart.max-file-size=100MB spring.servlet.multipart.max-request-size=1000MB

在java的包下新建一个config包，创建一个AliyunConfig.java

package com.example.ossdemo.config; import com.aliyun.oss.OSS; import com.aliyun.oss.OSSClient; import lombok.Data; import org.springframework.boot.context.properties.ConfigurationProperties; import org.springframework.context.annotation.Bean; import org.springframework.context.annotation.Configuration; import org.springframework.context.annotation.PropertySource; /** * @desc * * @author lastwhisper * @email gaojun56@163.com */ @Configuration @PropertySource(value = {"classpath:application-oss.properties"}) @ConfigurationProperties(prefix = "aliyun") @Data public class AliyunConfig { private String endpoint; private String accessKeyId; private String accessKeySecret; private String bucketName; private String urlPrefix; @Bean public OSS oSSClient() { return new OSSClient(endpoint, accessKeyId, accessKeySecret); } }

该实体类用于后台返回给前台

package com.example.ossdemo.vo; import lombok.Data; /** * @author lastwhisper * @desc 用于前后端交互的返回值 * @email gaojun56@163.com */ @Data public class FileUploadResult { // 文件唯一标识 private String uid; // 文件名 private String name; // 状态有：uploading done error removed private String status; // 服务端响应内容，如：'{"status": "success"}' private String response; }

service 在service使用ossClient操作阿里云OSS，进行上传、下载、删除、查看所有文件等操作，同时可以将图片的url进行入库操作。

controller

package com.example.ossdemo.controller; import com.aliyun.oss.model.OSSObjectSummary; import com.example.ossdemo.service.FileUploadService; import com.example.ossdemo.vo.FileUploadResult; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.http.HttpHeaders; import org.springframework.http.HttpStatus; import org.springframework.http.MediaType; import org.springframework.http.ResponseEntity; import org.springframework.stereotype.Controller; import org.springframework.web.bind.annotation.RequestMapping; import org.springframework.web.bind.annotation.RequestParam; import org.springframework.web.bind.annotation.ResponseBody; import org.springframework.web.multipart.MultipartFile; import javax.servlet.http.HttpServletResponse; import java.io.IOException; import java.io.InputStream; import java.net.URLEncoder; import java.util.List; /** * @author lastwhisper * @desc * @email gaojun56@163.com */ @Controller public class FileUploadController { @Autowired private FileUploadService fileUploadService; /** * @author lastwhisper * @desc 文件上传到oss * @return FileUploadResult * @Param uploadFile */ @RequestMapping("file/upload") @ResponseBody public FileUploadResult upload(@RequestParam("file") MultipartFile uploadFile) throws Exception { return this.fileUploadService.upload(uploadFile); } /** * @return FileUploadResult * @desc 根据文件名删除oss上的文件 * http://localhost:8080/file/delete?fileName=images/2019/04/28/1556429167175766.jpg * @author lastwhisper * @Param objectName */ @RequestMapping("file/delete") @ResponseBody public FileUploadResult delete(@RequestParam("fileName") String objectName) throws Exception { return this.fileUploadService.delete(objectName); } /** * @author lastwhisper * @desc 查询oss上的所有文件 * http://localhost:8080/file/list * @return List<OSSObjectSummary> * @Param */ @RequestMapping("file/list") @ResponseBody public List<OSSObjectSummary> list() throws Exception { return this.fileUploadService.list(); } /** * @author lastwhisper * @desc 根据文件名下载oss上的文件 * @return * @Param objectName */ @RequestMapping("file/download") @ResponseBody public void download(@RequestParam("fileName") String objectName, HttpServletResponse response) throws IOException { //通知浏览器以附件形式下载 response.setHeader("Content-Disposition", "attachment;filename=" + new String(objectName.getBytes(), "ISO-8859-1")); this.fileUploadService.exportOssFile(response.getOutputStream(),objectName); } }

前端页面编写与测试文件上传页面使用ajax异步文件上传到后端对接的OSS上。
