项目中使用阿里云进行图片上传

在项目中使用阿里云进行图片上传比较方便，前提是我们已经在阿里云注册好账号。
如果没有账号的也不要担心，直接注册就好。
具体实现代码

package com.leyou.upload.config;
import com.aliyun.oss.OSSClient;
import com.aliyun.oss.OSSException;
import com.aliyun.oss.model.ObjectMetadata;
import com.netflix.client.ClientException;
import org.springframework.web.multipart.MultipartFile;

import java.io.ByteArrayInputStream;
import java.io.FileNotFoundException;
import java.io.IOException;
import java.util.Date;

public class OssFileUtils {

    private static String endpoint = "oss-cn-beijing.aliyuncs.com";

    private static String accessKeyId = "LTAI4Fyr2W7bmRDcDF3qDp2p";

    private static String accessKeySecret = "08Fpt46p4tAnc2ukE7XWAEM04j6SjI";

    private static String bucketName = "dajiafly";

    /**
     * 功能描述:
     *
     * @param:[objectKey, multipartFile 文件的新名称]
     * @return:java.lang.String
     * @date:2018/10/14 15:46
     **/
    public static String uploadFile(String objectKey, MultipartFile multipartFile)
            throws OSSException, ClientException, FileNotFoundException {

        // 创建OSSClient的实例
        OSSClient ossClient  = new OSSClient(endpoint,accessKeyId,accessKeySecret);

        StringBuffer sb = new StringBuffer();
        // 上传的文件不是空，并且文件的名字不是空字符串
        if (multipartFile.getSize() != 0 && !"".equals(multipartFile.getName())) {
            ObjectMetadata om = new ObjectMetadata();
            om.setContentLength(multipartFile.getSize());
            // 设置文件上传到服务器的名称
            om.addUserMetadata("filename", objectKey);
            try {
                ossClient.putObject(bucketName, objectKey, new ByteArrayInputStream(multipartFile.getBytes()), om);
            } catch (IOException e) {

            }
        }
        // 设置这个文件地址的有效时间
        Date expiration = new Date(new Date().getTime() + 3600l * 1000 * 24 );
        String url = ossClient.generatePresignedUrl(bucketName, objectKey, expiration).toString();
        return url;
    }
}
