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 endpoint aliyun.oss.file.keyid=your accessKeyId aliyun.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.springframework.stereotype.Component;
@Component
public 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;
@Override
public 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.xiaogui.security.common.results.ResultEnum;
import com.xiaogui.security.common.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 {
@Autowired
private OssService ossService;
@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
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");
}
}
@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 keys = new ArrayList<>();
keys.add("course/1442295506745.jpg");
keys.add("2021/12/29/33840e4244de4f989e60710b8bd09d9c1234.jpeg");
keys.add("exampleobjectb.txt");
List result = ossService.deleteFileAll(keys);
return ResultResponse.of(result, ResultEnum.SUCCESS,true);
}
