阿里云OSS云存储删除（单个，指定的多个文件）删除文件

配置pom.xml

<!--阿里云OSS 依赖--><dependency><groupId>com.aliyun.oss</groupId><artifactId>aliyun-sdk-oss</artifactId><version>3.13.2</version></dependency><!-- 日期工具栏依赖 --><dependency><groupId>joda-time</groupId><artifactId>joda-time</artifactId><version>2.10.13</version></dependency><!--Java 9及以上的版本，则需要添加jaxb相关依赖--><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><dependency><groupId>org.glassfish.jaxb</groupId><artifactId>jaxb-runtime</artifactId><version>2.3.3</version></dependency>

配置application.properties或配置application.yml文件

#阿里云 OSS#不同的服务器，地址不同aliyun.oss.file.endpoint=your endpointaliyun.oss.file.keyid=your accessKeyIdaliyun.oss.file.keysecret=your accessKeySecret#bucket可以在控制台创建，也可以使用java代码创建aliyun.oss.file.bucketname=education-teacher

实现文件删除

创建常量读取工具类：ConstantPropertiesUtil.java

使用@Value读取application.properties里的配置内容

用spring的 InitializingBean 的 afterPropertiesSet 来初始化配置信息，这个方法将在所有的属性被初始化后调用。

package com.xiaogui.oss.utils;import org.springframework.beans.factory.InitializingBean;import org.springframework.beans.factory.annotation.Value;import org.ponent;/*** oss存储配置类* 当项目已启动，spring接口，spring加载之后，执行接口一个方法*/@Componentpublic class ConstantPropertiesUtils implements InitializingBean {//读取配置文件内容@Value("${aliyun.oss.file.endpoint}")private String endpoint;@Value("${aliyun.oss.file.keyid}")private String keyId;@Value("${aliyun.oss.file.keysecret}")private String keySecret;@Value("${aliyun.oss.file.bucketname}")private String bucketName;//定义公开静态常量public static String END_POINT;public static String ACCESS_KEY_ID;public static String ACCESS_KEY_SECRET;public static String BUCKET_NAME;@Overridepublic void afterPropertiesSet() throws Exception {END_POINT = endpoint;ACCESS_KEY_ID = keyId;ACCESS_KEY_SECRET = keySecret;BUCKET_NAME = bucketName;}}

编写删除文件接口controller OssController类

package com.xiaogui.oss.controller;import com.xiaogui.oss.service.OssService;import com.mon.results.ResultEnum;import com.mon.results.ResultResponse;import io.swagger.annotations.Api;import io.swagger.annotations.ApiOperation;import org.springframework.beans.factory.annotation.Autowired;import org.springframework.web.bind.annotation.*;import org.springframework.web.multipart.MultipartFile;import java.util.ArrayList;import java.util.List;@RestController@RequestMapping("fileOss")//@CrossOrigin // 跨域@Api(value = "文件删除oss", tags = "文件删除oss")public class OssController {@Autowiredprivate OssService ossService;/*** 删除文件远程方法*/@PostMapping(value = "deleteFile")@ApiOperation(value = "单个删除", notes = "单个删除")public ResultResponse deleteFile(String fileName) {//获取删除文件 fileName/*** 填写文件名。文件名包含路径，不包含Bucket名称。* 例如/09/14/52c6a3114e634979a2934f1ea12deaadfile.png。*/boolean flag = ossService.deleteFile(fileName);if (flag){return ResultResponse.of(true,101,"删除成功");} else {return ResultResponse.of(false,102,"删除失败");}}/*** 删除指定的多个文件*/@PostMapping(value = "deleteFileAll")@ApiOperation(value = "删除指定的多个文件", notes = "删除指定的多个文件")public ResultResponse deleteFileAll() {List<String> keys = new ArrayList<>();keys.add("course/1442295506745.jpg");keys.add("/12/29/33840e4244de4f989e60710b8bd09d9c1234.jpeg");keys.add("exampleobjectb.txt");List<String> result = ossService.deleteFileAll(keys);return ResultResponse.of(result, ResultEnum.SUCCESS,true);}
