目前項目是spring boot+mysql+maven,由於須要數據庫版本管理,於是集成flywayhtml
pom.xml
中加入依賴<dependency> <groupId>org.flywaydb</groupId> <artifactId>flyway-core</artifactId> <version>5.2.4</version> </dependency>
cd src/main/resources mkdir db/migration
導出數據庫java
mysqldump -uroot -p Mydb >Mydb.sql
清空數據庫mysql
drop database Mydb; create schema Mydb default character set utf8 collate utf8_general_ci;
db/migration
中mv Mydb.sql db/migration/V1__init.sql
#編譯打包 mvn package #運行項目 java -jar target/myproject-0.0.1-SNAPSHOT.jar
數據庫和未集成前一致,且多一個schema_version
表,該表是flyway進行版本管理的主表spring
這個方法簡單粗暴,用於數據量不大的狀況,若是對於現有的數據庫並不想動能夠用Baseline
方案解決,🚩之後有時間寫一下這個方案sql
方法一:在application.properties 或者 application.yml 中配置數據庫
# FLYWAY (FlywayProperties) spring.flyway.baseline-description=<< Flyway Baseline >> # Description to tag an existing schema with when applying a baseline. spring.flyway.baseline-on-migrate=false # Whether to automatically call baseline when migrating a non-empty schema. spring.flyway.baseline-version=1 # Version to tag an existing schema with when executing baseline. spring.flyway.check-location=true # Whether to check that migration scripts location exists. spring.flyway.clean-disabled=false # Whether to disable cleaning of the database. spring.flyway.clean-on-validation-error=false # Whether to automatically call clean when a validation error occurs. spring.flyway.connect-retries=0 # Maximum number of retries when attempting to connect to the database. spring.flyway.enabled=true # Whether to enable flyway. spring.flyway.encoding=UTF-8 # Encoding of SQL migrations. spring.flyway.group=false # Whether to group all pending migrations together in the same transaction when applying them. spring.flyway.ignore-future-migrations=true # Whether to ignore future migrations when reading the schema history table. spring.flyway.ignore-ignored-migrations=false # Whether to ignore ignored migrations when reading the schema history table. spring.flyway.ignore-missing-migrations=false # Whether to ignore missing migrations when reading the schema history table. spring.flyway.ignore-pending-migrations=false # Whether to ignore pending migrations when reading the schema history table. spring.flyway.init-sqls= # SQL statements to execute to initialize a connection immediately after obtaining it. spring.flyway.installed-by= # Username recorded in the schema history table as having applied the migration. spring.flyway.locations=classpath:db/migration # Locations of migrations scripts.

If not set, the primary configured data source is used. spring.flyway.user= # Login user of the database to migrate. spring.flyway.validate-on-migrate=true # Whether to automatically call validate when performing a migration.
方法二:用環境變量配置
略springboot
Execute Flyway Database Migrations on Startup
spring boot 開箱集成flyway
