1、添加依赖
<dependency>
<groupId>p6spy</groupId>
<artifactId>p6spy</artifactId>
<version>3.7.0</version>
</dependency>
2、新建spy.properties
# 自定义日志打印
logMessageFormat=com.p6spy.engine.spy.appender.CustomLineFormat
customLogMessageFormat=%(currentTime) | SQL耗时： %(executionTime) ms | 连接信息： %(category)-%(connectionId) | 执行语句： %(sql)
module.log=com.p6spy.engine.logging.P6LogFactory,com.p6spy.engine.outage.P6OutageFactory
# 自定义日志打印
#logMessageFormat=org.pkaq.core.log.P6SpyLogger
# 使用日志系统记录sql
appender=com.p6spy.engine.spy.appender.Slf4JLogger
## 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
# 日期格式
dateformat=yyyy-MM-dd HH:mm:ss
# 实际驱动
driverlist=com.mysql.jdbc.Driver
# 是否开启慢SQL记录
outagedetection=true
# 慢SQL记录标准 秒
outagedetectioninterval=2
也可以自定义输出格式
3、修改数据库配置文件
spring.datasource.driver-class-name=com.p6spy.engine.spy.P6SpyDriver
spring.datasource.url=jdbc:p6spy:mysql:///houserent?serverTimezone=GMT%2B8

（文件内容太多了，仅附上几处重要的）
#################################################################
# MODULES #
# #
# Modules provide the P6Spy functionality. If a module, such #
# as module_log is commented out, that functionality will not #
# be available. If it is not commented out (if it is active), #
# the functionality will be active. #
# #
# Values set in Modules cannot be reloaded using the #
# reloadproperties variable. Once they are loaded, they remain #
# in memory until the application is restarted. #
# #
#################################################################
#第一：module.log的属性必须配置，如果不配置，P6SPY将不起任何作用，典型配置：
module.log=com.p6spy.engine.logging.P6LogFactory
#module.outage=com.p6spy.engine.outage.P6OutageFactory
#################################################################
# REALDRIVER(s) #
# #
# In your application server configuration file you replace the #
# "real driver" name with com.p6spy.engine.P6SpyDriver. This is #
# where you put the name of your real driver P6Spy can find and #
# register your real driver to do the database work. #
# #
# If your application uses several drivers specify them in #
# realdriver2, realdriver3\. See the documentation for more #
# details. #
# #
# Values set in REALDRIVER(s) cannot be reloaded using the #
# reloadproperties variable. Once they are loaded, they remain #
# in memory until the application is restarted. #
# #
#################################################################
#第二：数据库驱动配置，你懂的，不多说了
# oracle driver
# realdriver=oracle.jdbc.driver.OracleDriver
# mysql Connector/J driver
# realdriver=com.mysql.jdbc.Driver
# informix driver
# realdriver=com.informix.jdbc.IfxDriver
# ibm db2 driver
# realdriver=COM.ibm.db2.jdbc.net.DB2Driver
# the mysql open source driver
realdriver=org.gjt.mm.mysql.Driver
#specifies another driver to use
realdriver2=
#specifies a third driver to use
realdriver3=
#第三：appender配置，一般分为三种
#specifies the appender to use for logging
#appender=com.p6spy.engine.logging.appender.Log4jLogger
#控制台
#appender=com.p6spy.engine.logging.appender.StdoutLogger
appender=com.p6spy.engine.logging.appender.FileLogger
# name of logfile to use, note Windows users should make sure to use forward slashes in their pathname (e:/test/spy.log) (used for file logger only)
#日志文件存放路径及文件名
logfile = spy.log
# append to the p6spy log file. if this is set to false the
# log file is truncated every time. (file logger only)
append=true
#The following are for log4j logging only
log4j.appender.STDOUT=org.apache.log4j.ConsoleAppender
log4j.appender.STDOUT.layout=org.apache.log4j.PatternLayout
log4j.appender.STDOUT.layout.ConversionPattern=p6spy - %m%n
log4j.logger.p6spy=INFO,STDOUT
