三、配置
application.properties
# flyway配置
#spring.datasource.url=jdbc:mysql://localhost:3306/test?serverTimezone=UTC&useUnicode=true&characterEncoding=utf-8&allowMultiQueries=true&autoReconnect=true&useSSL=false
#spring.datasource.username=root
#spring.datasource.password=123456
#spring.datasource.driver-class-name=com.mysql.jdbc.Driver
# 是否開啓flyway，默認是 true,如果打算一直用flyway可以不用配置。當某次執行代碼時不想用flyway 時可以把此項設爲false；
spring.flyway.enabled=true
# 當遷移時發現目標schema非空，而且帶有沒有元數據的表時，是否自動執行基準遷移，默認false.
spring.flyway.baseline-on-migrate=true
# 配合 baseline-on-migrate 使用，因爲創建 flyway_schema_history 表時也會佔用一條記錄，如果不加初始版本=0，那麼V1裏的sql就不會執行
# （這個問題我一開始還以爲它就是這麼設計的，第一個版本我以爲就是被佔用的,直到我發現別人的是可以執行的。。。。）
spring.flyway.baseline-version=0
# 遷移腳本的位置，默認db/migration.
spring.flyway.locations=classpath:/db/migration
# flyway和p6spy連用
spring.datasource.driver-class-name=com.p6spy.engine.spy.P6SpyDriver
spring.datasource.url=jdbc:p6spy:mysql://localhost:3306/test?serverTimezone=UTC&useUnicode=true&characterEncoding=utf-8&allowMultiQueries=true&autoReconnect=true&useSSL=true

# 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

################################################################
# 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
四、配置sql文件 注意：如果想讓flyway生效必須採用V1.1__開頭，再加名稱，隨便取，再.sql；案例：V1.1__Base.sql
再說第二遍
如果resource文件夾沒有db/migration文件夾 ，不要擔心，直接在resource下創建db/migration文件夾，裏面放入自己寫的.sql文件，格式如下： V或者R開頭（注意，必須是大寫），然後版本號（數字），兩個英文的下劃線，接上名字再加上.sql
DROP TABLE IF EXISTS user ;
CREATE TABLE `user` (
`id` bigint(64) NOT NULL AUTO_INCREMENT COMMENT '主鍵',
`name` varchar(64) NOT NULL COMMENT '姓名',
`age` int(3) DEFAULT NULL COMMENT '年齡',
PRIMARY KEY (`id`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8mb4;
五、啓動方式：
package com.citydo.flywayp6spy;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
@SpringBootApplication
public class Flywayp6spyApplication {
public static void main(String[] args) {
SpringApplication.run(Flywayp6spyApplication.class, args);
}
}
六、p6spy插件啓動
當出現打印sql腳本，說明配置成功
當SpringBoot啓動時，文件會自動被使用。以V開頭的文件會只會生效第一次，而以R開頭的文件每次啓動SpringBoot都會使用一次。
當成功後可以看到test數據庫中有一個自動生成的名叫user的表
