编写配置文件

server:port: 8080aliyun:endpoint: oss-cn-wuhan-lr.aliyuncs.comaccessKey: your-accessKeysecretKey: your-secretKeybucketname: nullpointer2024

编写配置aliyun配置类

package com.orchids.aliyunoss.aliyun;import lombok.Data;
import org.springframework.boot.context.properties.ConfigurationProperties;/*** @ Author qwh* @ Date 2024/6/27 14:38*/
@Data
@ConfigurationProperties(prefix = "aliyun")
public class AliyunProperties {private String endpoint;private String accessKey;private String secretKey;private String bucketName;
}

package com.orchids.aliyunoss.aliyun;import com.aliyun.oss.OSS;
import com.aliyun.oss.OSSClient;
import com.aliyun.oss.OSSClientBuilder;
import lombok.Data;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.context.properties.EnableConfigurationProperties;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;/*** @ Author qwh* @ Date 2024/6/27 14:39*/
@Configuration
@EnableConfigurationProperties(AliyunProperties.class)
public class AliyunConfiguration {@Autowiredprivate AliyunProperties aliyunProperties;@Beanpublic OSS ossClient(){return new OSSClientBuilder().build(aliyunProperties.getEndpoint(),aliyunProperties.getAccessKey(),aliyunProperties.getSecretKey());}}

编写knife4j配置文件

package com.orchids.aliyunoss.web.config;import io.swagger.v3.oas.models.OpenAPI;
import io.swagger.v3.oas.models.info.Info;
import org.springdoc.core.GroupedOpenApi;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;/*** @ Author qwh* @ Date 2024/6/27 14:54*/
@Configuration
public class Knife4jConfiguration {@Beanpublic OpenAPI OpenAPI() {return new OpenAPI().info(new Info().title("AliyunOSSAPI").version("1.0").description("UploadAPI"));}@Beanpublic GroupedOpenApi StudentAPI() {return GroupedOpenApi.builder().group("AliyunOssFile管理").pathsToMatch("/aliyun/**").build();}
}

结果返回类

package com.orchids.aliyunoss.model.result;import lombok.Data;/*** @ Author qwh* @ Date 2024/6/27 14:37*/
@Data
public class Result<T>{//返回码private Integer code;//返回消息private String message;//返回数据private T data;public Result() {}private static <T> Result<T> build(T data) {Result<T> result = new Result<>();if (data != null)result.setData(data);return result;}public static <T> Result<T> build(T body, ResultCode resultCodeEnum) {Result<T> result = build(body);result.setCode(resultCodeEnum.getCode());result.setMessage(resultCodeEnum.getMessage());return result;}public static <T> Result<T> ok(T data) {return build(data, ResultCode.SUCCESS);}public static <T> Result<T> ok() {return Result.ok(null);}public static <T> Result<T> fail() {return build(null, ResultCode.FAIL);}
}

controller
