springboot 整合 oss

一、阿里云配置

获取

accessKeyId
accessSecret

创建桶

bucketName

二、demo

1、oss.config

import org.springframework.beans.factory.annotation.Value;
import org.springframework.context.annotation.Configuration;
import lombok.Data;

@Data
@Configuration
public class OssConfig {
    @Value("${aliyun.oss.endpoint}")
    private String endpoint;

    @Value("${aliyun.oss.accessKeyId}")
    private String accessKeyId;

    @Value("${aliyun.oss.accessSecret}")
    private String accessSecret;

    @Value("${aliyun.oss.bucketName}")
    private String bucketName;
}

2、依赖

<dependency>
       <groupId>com.aliyun.oss</groupId>
       <artifactId>aliyun-sdk-oss</artifactId>
       <version>3.10.2</version>
</dependency>

3、application.properties

#服务端
server.port=8002
#服务器
spring.application.name=service-oss

aliyun.oss.endpoint=oss-cn-hangzhou.aliyuncs.com　　//管控台的endpoint地址
aliyun.oss.accessKeyId=xxxxxxxx　　　　　　　　　　　　//从阿里云服务器配置
aliyun.oss.accessSecret=xxxxxxxxxx　　　　　　　　  　//从阿里云服务器配置
aliyun.oss.bucketName=dev-fileupload　　　　　　　　  //服务器配置的文件夹名称

# 上传文件大小
spring.servlet.multipart.max-file-size=100MB
spring.servlet.multipart.max-request-size=100MB

3、测试demo

import com.congge.service.OssService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.PostMapping;
import org.springframework.web.bind.annotation.RestController;
import org.springframework.web.multipart.MultipartFile;

@RestController
public class OssController {
    @Autowired
    private OssService ossService;

    @PostMapping
    public String uploadOssFile(MultipartFile file) throws Exception{
        String url = ossService.uploadFileAvatar(file);
        return url;
    }
}

import com.aliyun.oss.OSS;
import com.aliyun.oss.OSSClient;
import com.congge.configs.ConstantPropertiesUtils;
import com.congge.service.OssService;
import org.springframework.stereotype.Service;
import org.springframework.web.multipart.MultipartFile;
import java.io.InputStream;
import java.util.UUID;

@Service
public class OssServiceImpl implements OssService {
    @Override
    public String uploadFileAvatar(MultipartFile file)  throws Exception{//创建实例
        OSS ossClient = new OSSClient(endpoint, accessKeyId, accessKeySecret);
        //获取上传文件输入流
        InputStream inputStream = file.getInputStream();
        //获取文件名称
        String fileName = file.getOriginalFilename();
        //保证文件名唯一，去掉uuid中的'-'
        String uuid = UUID.randomUUID().toString().replaceAll("-", "");
        fileName = uuid + fileName;
        //把文件按日期分类，构建日期路径
        String datePath = new Date().toString("yyyy/MM/dd");
//拼接
        fileName = datePath + "/" + fileName;
        //上传到阿里云
        ossClient.putObject(bucketName, fileName, inputStream);
        //把上传后把文件url返回
        url = "https://" + bucketName + "." + endpoint + "/" + fileName;
        //关闭OSSClient
        ossClient.shutdown();
        return url;
    }
}

@SpringBootApplication
public class Test {
    public static void main(String[] args) {
        SpringApplication.run(Test.class,args);
    }
}
