配置类

yml文件为
test:sftp:ftpHost: 127.0.0.1portL: 22ftpUserName: rootftpPassword: rootvpsUrl: /data/test/img	@Data
@Configuration
@ConfigurationProperties(prefix = "test.sftp")
public class SftpConfig {/*服务器IP*/private String ftpHost;/*服务器端口*/private Integer portL;/*服务器-用户名称*/private String ftpUserName;/*服务器用户密码*/private String ftpPassword;/*上传文件位置*/private String vpsUrl;}

调用

 @Resourceprivate SFTPUtils sftpUtils;//这里两个方法分别可以传 网络图片的url地址或者流
String fqFm = sftpUtils.uploadFileSFTP('图片url');
