[英]How to build flyway java-based migrations
I'm using flyway command-line tool to handle my db migrations.我正在使用 flyway 命令行工具来处理我的数据库迁移。 Till now all migrations are sql
直到现在所有的迁移都是 sql
Config file(only used options):配置文件(仅使用的选项):
flyway.url=jdbc:postgresql://db.host
flyway.user=user
flyway.password=password
flyway.table=flyway_migrations
flyway.locations=filesystem:/home/........./sql/migrations
flyway.sqlMigrationPrefix=update
flyway.validateOnMigrate=false
flyway.outOfOrder=true
That works perfectly.这完美地工作。
But for now I need to add one java-based migration.但是现在我需要添加一个基于 Java 的迁移。 And I'm really puzzled I can't find any How todo examples.
我真的很困惑我找不到任何 How todo 示例。 How to compile, where to put java migrations.
如何编译,将java迁移放在哪里。
I've tried simple migration-class from official documentation:我从官方文档中尝试了简单的迁移类:
package db.migration;
import org.flywaydb.core.api.migration.jdbc.JdbcMigration;
import java.sql.Connection;
import java.sql.PreparedStatement;
/**
* Example of a Java-based migration.
*/
public class V50_121_1__update_notes implements JdbcMigration {
public void migrate(Connection connection) throws Exception {
PreparedStatement statement =
connection.prepareStatement("INSERT INTO test_user (name) VALUES ('Obelix')");
try {
statement.execute();
} finally {
statement.close();
}
}
}
But what to do next?但是接下来该怎么办? Tried compiling:
尝试编译:
javac -cp "./flyway-core-3.2.1.jar" V50_121_1__update_notes.java
jar cf V50_121_1__update_dataNode_notes.jar V50_121_1__update_dataNode_notes.class
And then putting that jar to different locations, have no effect.然后把那个罐子放在不同的位置,没有效果。
flyway info - don't see the migration.飞行路线信息 - 看不到迁移。
So how to build the simplest java-based migration.那么如何构建最简单的基于java的迁移。 I will prefer not to use Maven, or something similar.
我宁愿不使用 Maven 或类似的东西。 Just simple jar file(???) which is picked up by flyway command-line tool.
只是简单的 jar 文件(???),由 flyway 命令行工具拾取。
Thank you.谢谢你。
Make sure your .class
file is in a db/migration
directory inside your .jar
file file and that your .jar
file is placed in the /jars
directory of your Flyway installations.确保您的
.class
文件位于.jar
文件中的db/migration
目录中,并且您的.jar
文件位于 Flyway 安装的/jars
目录中。
flyway.locations
should also be set to: flyway.locations
也应设置为:
db.migration,filesystem:/home/........./sql/migrations
Specify for .java
files as .java
como将
.java
文件指定为.java
como
classpath : package_example.migrations
类路径:
package_example.migrations
flyway.url=jdbc:postgresql://db.host
flyway.user=user
flyway.password=password
flyway.table=flyway_migrations
flyway.locations=filesystem:/home/...../sql/migrations,classpath:pack_example.migrations
flyway.sqlMigrationPrefix=update
flyway.validateOnMigrate=false
flyway.outOfOrder=true
