编写配置文件

server:
  port: 8080

aliyun:
  endpoint: oss-cn-wuhan-lr.aliyuncs.com
  accessKey: your-accessKey
  secretKey: your-secretKey
  bucketname: 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 {
    @Autowired
    private AliyunProperties aliyunProperties;
    @Bean
    public 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 {
    @Bean
    public OpenAPI OpenAPI() {
        return new OpenAPI().info(
                new Info()
                        .title("AliyunOSSAPI")
                        .version("1.0")
                        .description("UploadAPI"));
    }
    @Bean
    public 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

package com.orchids.aliyunoss.web.controller;
