如上图，一般我们打印的日志都是参数都是问号，看起来不够直观，这时候可以考虑用P6SPY。
引入依赖：

  <dependency>
            <groupId>p6spy</groupId>
            <artifactId>p6spy</artifactId>
            <version>3.9.1</version>
  </dependency>

替换JDBC驱动，并在数据源配置Url中添加p6spy:

格式化输出配置：

import com.p6spy.engine.spy.appender.MessageFormattingStrategy;
import org.apache.commons.lang3.StringUtils;

import java.time.LocalDateTime;
import java.time.format.DateTimeFormatter;

/**
 * SQL格式化输出
 */

public class P6spySqlFormatConfigure implements MessageFormattingStrategy {

    /**
     * sql格式化输出
     */
    @Override
    public String formatMessage(int connectionId, String now, long elapsed, String category, String prepared, String sql, String url) {
        return StringUtils.isNotBlank(sql) ? formatFullTime(LocalDateTime.now(), DateUtil.FULL_TIME_SPLIT_PATTERN)
                + " | 耗时 " + elapsed + " ms | SQL 语句：" + StringUtils.LF + sql.replaceAll("[\\s]+", StringUtils.SPACE) + ";" : StringUtils.EMPTY;
    }

    /**
     * 日期格式化
     */
    public  String formatFullTime(LocalDateTime localDateTime, String pattern) {
        DateTimeFormatter dateTimeFormatter = DateTimeFormatter.ofPattern(pattern);
        return localDateTime.format(dateTimeFormatter);
    }
}

用到的时间工具类：

import java.text.ParseException;
import java.text.SimpleDateFormat;
import java.time.Instant;
import java.time.LocalDateTime;
import java.time.ZoneId;
import java.time.format.DateTimeFormatter;
import java.util.Date;
import java.util.Locale;

/**
 * 时间工具类
 */
public class DateUtil {

    public static final String FULL_TIME_PATTERN = "yyyyMMddHHmmss";

    public static final String FULL_TIME_SPLIT_PATTERN = "yyyy-MM-dd HH:mm:ss";

    public static final String CST_TIME_PATTERN = "EEE MMM dd HH:mm:ss zzz yyyy";

    public static String formatFullTime(LocalDateTime localDateTime) {
        return formatFullTime(localDateTime, FULL_TIME_PATTERN);
    }

    public static String formatFullTime(LocalDateTime localDateTime, String pattern) {
        DateTimeFormatter dateTimeFormatter = DateTimeFormatter.ofPattern(pattern);
        return localDateTime.format(dateTimeFormatter);
    }

    public static String getDateFormat(Date date, String dateFormatType) {
        SimpleDateFormat simpleDateFormat = new SimpleDateFormat(dateFormatType, Locale.CHINA);
        return simpleDateFormat.format(date);
    }

    public static String formatCstTime(String date, String format) throws ParseException {
        SimpleDateFormat simpleDateFormat = new SimpleDateFormat(CST_TIME_PATTERN, Locale.US);
        Date usDate = simpleDateFormat.parse(date);
        return DateUtil.getDateFormat(usDate, format);
    }

    public static String formatInstant(Instant instant, String format) {
        LocalDateTime localDateTime = LocalDateTime.ofInstant(instant, ZoneId.systemDefault());
        return localDateTime.format(DateTimeFormatter.ofPattern(format));
    }
}

sys.properties配置文件：

# 使用日志系统记录 sql
appender=com.p6spy.engine.spy.appender.Slf4JLogger
# 自定义日志打印
logMessageFormat=com.study.p6spy.P6spySqlFormatConfigure
## 配置记录Log例外
excludecategories=info,debug,result,batc,resultset
# 设置使用p6spy driver来做代理
deregisterdrivers=true
# 是否开启慢 SQL记录
outagedetection=true
# 慢 SQL记录标准 2 秒
outagedetectioninterval=2
# 开启过滤
filter=true
# 包含 QRTZ的不打印
#exclude=QRTZ,select 1

控制台日志如下：
