import org.slf4j.Logger;
import org.slf4j.LoggerFactory;

import java.util.Map;

/**

 */
public class SmsSenderUtilTest {

    private static Logger logger = LoggerFactory.getLogger(SmsSenderUtilTest.class);

    @Test
    public void testLog() {
        logger.info("测试打印日志：{}", System.currentTimeMillis());
    }
}

运行结果
