用sftp推送zip包到目标服务器

• 任务类里面，主要功能是，定时采集三张表的数据，并把数据转换成csv，三份csv压缩成一个加密的zip包，通过sftp推送到指定的目录下

配置类

@Data
@Configuration
@ConfigurationProperties(prefix = "sftp.zip")
public class SftpConfig {private String host;private int port = 22;private String username;private String password;private String remoteDir;private String zipPassword;private String cron;
}
