1.创建一个Maven项目
2.编辑当下的pom.xml，添加flyway依赖和Mysql依赖
<project ...> ... <dependencies> <dependency> <groupId>com.googlecode.flyway</groupId> <artifactId>flyway-core</artifactId> <version>3.2.1</version> </dependency> <dependency> <groupId>mysql</groupId> <artifactId>mysql-connector-java</artifactId> <version>5.1.6</version> </dependency> ... </dependencies> ... </project>
3.整合flyway
现在我们可以将Flyway的代码放入项目中，并配置数据库，例如增加到默认生成的：src/main/java/foobar/App.java
package foobar; import com.googlecode.flyway.core.Flyway; public class App { public static void main(String[] args) { // 创建Flyway实例 Flyway flyway = new Flyway(); // 设置数据库 flyway.setDataSource("jdbc:mysql://localhost:3306/foobar", "user", "pass"); // 开始迁移 flyway.migrate(); } }
4.创建第一个数据迁移
创建数据迁移目录src/main/resources/db/migration，
执行命令mkdir -p src/main/resources/db/migration
创建我们的第一个数据迁移src/main/resources/db/migration/V1__Create_person_table.sql
CREATE TABLE person ( id INT, name VARCHAR(100) );
5.执行App.java
执行App.java（也可以直接在IDE中执行main方法）
mvn package exec:java -Dexec.mainClass=foobar.App -Dmaven.test.skip=true
如果你成功了，应该会得到如下信息
INFO: Creating Metadata table: `foobar`.`schema_version` Feb 27, 2014 12:20:18 AM com.googlecode.flyway.core.command.DbMigrate migrate INFO: Current version of schema `foobar`: << Empty Schema >> Feb 27, 2014 12:20:18 AM com.googlecode.flyway.core.command.DbMigrate applyMigration INFO: Migrating schema `foobar` to version 1 Feb 27, 2014 12:20:18 AM com.googlecode.flyway.core.command.DbMigrate logSummary INFO: Successfully applied 1 migration to schema `foobar` (execution time 00:00.194s).
6.继续添加数据迁移
假如我们现在需要增加第二个数据迁移，命名为：src/main/resources/db/migration/V2__Add_people.sql
INSERT INTO person (id, name) VALUES (1, ‘Axel‘); INSERT INTO person (id, name) VALUES (2, ‘Mr. Foo‘); INSERT INTO person (id, name) VALUES (3, ‘Ms. Bar‘);
执行命令
mvn package exec:java -Dexec.mainClass=foobar.App -Dmaven.test.skip=true
输出如下
Feb 27, 2014 12:25:00 AM com.googlecode.flyway.core.command.DbMigrate migrate INFO: Current version of schema `foobar`: 1 Feb 27, 2014 12:25:00 AM com.googlecode.flyway.core.command.DbMigrate applyMigration INFO: Migrating schema `foobar` to version 2 Feb 27, 2014 12:25:00 AM com.googlecode.flyway.core.command.DbMigrate logSummary INFO: Successfully applied 1 migration to schema `foobar` (execution time 00:00.047s).
