1、首先创建一个springboot项目
在pom.xml中导入p6spy
<!-- 将p6spy导入 -->
<dependency>
<groupId>p6spy</groupId>
<artifactId>p6spy</artifactId>
<version>3.8.6</version>
</dependency>
<!-- 连接mysql -->
<dependency>
<groupId>org.mybatis.spring.boot</groupId>
<artifactId>mybatis-spring-boot-starter</artifactId>
<version>2.0.0</version>
</dependency>
<dependency>
<groupId>mysql</groupId>
<artifactId>mysql-connector-java</artifactId>
<scope>runtime</scope>
</dependency>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-jdbc</artifactId>
</dependency>在application.properties中
#mybatis config
#spring.datasource.driver-class-name=com.mysql.jdbc.Driver
#spring.datasource.url=jdbc:mysql://localhost:3306/db?serverTimezone=CTT&useUnicode=true&characterEncoding=utf-8&allowMultiQueries=true&useSSL=true
#更换为com.p6spy.engine.spy.P6SpyDriver
spring.datasource.driver-class-name=com.p6spy.engine.spy.P6SpyDriver
spring.datasource.url=jdbc:p6spy:mysql://localhost:3306/data?serverTimezone=CTT&useUnicode=true&characterEncoding=utf-8&allowMultiQueries=true&useSSL=true
spring.datasource.username=root
spring.datasource.password=123456在和application.properties同目录下创建一个spy.properties配置文件

#################################################################
# DataSource replacement #
# #
# Replace the real DataSource class in your application server #
# configuration with the name com.p6spy.engine.spy.P6DataSource #
# (that provides also connection pooling and xa support). #
# then add the JNDI name and class name of the real #
# DataSource here #
# #
# Values set in this item cannot be reloaded using the #
# reloadproperties variable. Once it is loaded, it remains #
# in memory until the application is restarted. #
# #
#################################################################
#realdatasource=/RealMySqlDS
#realdatasourceclass=com.mysql.jdbc.jdbc2.optional.MysqlDataSource
#################################################################
# DataSource properties #
# #
# If you are using the DataSource support to intercept calls #
# to a DataSource that requires properties for proper setup, #
# define those properties here. Use name value pairs, separate #
# the name and value with a semicolon, and separate the #
# pairs with commas. #
# #
# The example shown here is for mysql #
# #
#################################################################
#realdatasourceproperties=port;3306,serverName;myhost,databaseName;jbossdb,foo;bar
#################################################################
# JNDI DataSource lookup #
# #
# If you are using the DataSource support outside of an app #
# server, you will probably need to define the JNDI Context #
# environment. #
# #
# If the P6Spy code will be executing inside an app server then #
# do not use these properties, and the DataSource lookup will #
# use the naming context defined by the app server. #
# #
# The two standard elements of the naming environment are #
# jndicontextfactory and jndicontextproviderurl. If you need #
# additional elements, use the jndicontextcustom property. #
# You can define multiple properties in jndicontextcustom, #
# in name value pairs. Separate the name and value with a #
# semicolon, and separate the pairs with commas. #
# #
# The example shown here is for a standalone program running on #
# a machine that is also running JBoss, so the JNDI context #
# is configured for JBoss (3.0.4). #
# #
# (by default all these are empty) #
#################################################################
#jndicontextfactory=org.jnp.interfaces.NamingContextFactory
#jndicontextproviderurl=localhost:1099
#jndicontextcustom=java.naming.factory.url.pkgs;org.jboss.naming:org.jnp.interfaces
#jndicontextfactory=com.ibm.websphere.naming.WsnInitialContextFactory
#jndicontextproviderurl=iiop://localhost:900
################################################################
# P6 LOGGING SPECIFIC PROPERTIES #
################################################################
# filter what is logged
# please note this is a precondition for usage of: include/exclude/sqlexpression
# (default is false)
#filter=false
# comma separated list of strings to include
# please note that special characters escaping (used in java) has to be done for the provided regular expression
# (default is empty)
#include=
# comma separated list of strings to exclude
# (default is empty)
#exclude=
# sql expression to evaluate if using regex
# please note that special characters escaping (used in java) has to be done for the provided regular expression
# (default is empty)
#sqlexpression=
#list of categories to exclude: error, info, batch, debug, statement,
#commit, rollback, result and resultset are valid values
# (default is info,debug,result,resultset,batch)
#excludecategories=info,debug,result,resultset,batch
#whether the binary values (passed to DB or retrieved ones) should be logged with placeholder: [binary] or not.
# (default is false)
#excludebinary=false
# Execution threshold applies to the standard logging of P6Spy.
# While the standard logging logs out every statement
# regardless of its execution time, this feature puts a time
# condition on that logging. Only statements that have taken
# longer than the time specified (in milliseconds) will be
# logged. This way it is possible to see only statements that
# have exceeded some high water mark.
# This time is reloadable.
#
# executionThreshold=integer time (milliseconds)
# (default is 0)
#executionThreshold=
################################################################
# P6 OUTAGE SPECIFIC PROPERTIES #
################################################################
# Outage Detection
#
# This feature detects long-running statements that may be indicative of
# a database outage problem. If this feature is turned on, it will log any
# statement that surpasses the configurable time boundary during its execution.
# When this feature is enabled, no other statements are logged except the long
# running statements. The interval property is the boundary time set in seconds.
# For example, if this is set to 2, then any statement requiring at least 2
# seconds will be logged. Note that the same statement will continue to be logged
# for as long as it executes. So if the interval is set to 2, and the query takes
# 11 seconds, it will be logged 5 times (at the 2, 4, 6, 8, 10 second intervals).
#
# outagedetection=true|false
# outagedetectioninterval=integer time (seconds)
#
# (default is false)
#outagedetection=false
# (default is 60)
#outagedetectioninterval=30到这里，
p6spy就可以工作了！
编写相应的Control运行效果如下：
可以看到默认的log格式可能不能满足需求，我们也可以自定义：
编写类实现com.p6spy.engine.spy.appender.MessageFormattingStrategy接口，重写formatMessage方法：
import com.p6spy.engine.common.P6Util;
import com.p6spy.engine.spy.appender.MessageFormattingStrategy;
import java.text.SimpleDateFormat;
/**
* now + "|" + elapsed + "|" + category + "|connection " + connectionId + "|url " + url + "|" + P6Util.singleLine(prepared) + "|" + P6Util.singleLine(sql);
* #01-07-20 14:37:38:871 | took 1ms | statement | connection 0| url jdbc:p6spy:mysql://localhost:3306/data?serverTimezone=CTT&useUnicode=true&characterEncoding=utf-8&allowMultiQueries=true&useSSL=true
*/
public class P6SpyLogger implements MessageFormattingStrategy {
private SimpleDateFormat format = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss:SSS");
@Override
public String formatMessage(int connectionId, String now, long elapsed, String category, String prepared, String sql, String url) {
StringBuilder sb = new StringBuilder();
sb
.append("=====================================================\n")
.append("连接id：").append(connectionId).append("\n")
.append("当前时间：").append(now).append("\n")
.append("类别：").append(category).append("\n")
.append("花费时间：").append(elapsed).append("\n")
// .append("url：").append(url).append("\n")
.append("预编译sql：").append(P6Util.singleLine(prepared)).append("\n")
.append("最终执行的sql：").append(P6Util.singleLine(sql))
.append("\n=====================================================\n");
return sb.toString();
}
}在spy.properties中将logMessageFormat改成你编写实现MessageFormattingStrategy接口类的全类名
logMessageFormat=《你编写log格式类全类名》
