如何使用Flyway配置来处理多个数据库
我们有一个使用maven配置的Java应用程序，该应用程序使用多个数据库。这是一个应用程序-许多架构。
我已经配置了flyway，已经过测试，并且效果很好，但是我的配置仅适用于一个数据库。
这是我的pom.xml使用一种模式进行测试：
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd"> <modelVersion>4.0.0</modelVersion>
<groupId>com.test</groupId>
<artifactId>test</artifactId>
<version>0.0.1-SNAPSHOT</version>
<build>
<plugins>
<!-- Flyway plugin configuration -->
<plugin>
<groupId>org.flywaydb</groupId>
<artifactId>flyway-maven-plugin</artifactId>
<version>3.0</version>
<configuration>
<url>jdbc:mysql://localhost:3306/argentina</url>
<user>test</user>
<password>test</password>
</configuration>
<dependencies>
<dependency>
<groupId>mysql</groupId>
<artifactId>mysql-connector-java</artifactId>
<version>5.1.21</version>
</dependency>
</dependencies>
</plugin>
</plugins>
</build>
<dependencies>
<dependency>
<!-- alllll my dependency list -->
</dependency>
<!-- DB dependencies -->
<dependency>
<groupId>mysql</groupId>
<artifactId>mysql-connector-java</artifactId>
<version>5.1.21</version>
</dependency>
</dependencies>
</project>
更新：通过使用现在提供的答案，我将以下pom.xml配置为2个模式。
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd"> <modelVersion>4.0.0</modelVersion>

我执行飞行操作，但没有成功，这是我收到的错误：

数据库配置正常。另外，我检查了架构是否还可以。
更新：我从命令行飞行通道中删除：它运行良好。谢谢Jk1
回答：
您可以为具有不同配置的单个插件指定多个执行：
<plugin> <groupId>org.flywaydb</groupId>
<artifactId>flyway-maven-plugin</artifactId>
<version>3.0</version>
<executions>
<execution>
<id>first-execution</id>
<phase>compile</phase> <!--whatever phase you need-->
<goals>
<goal>migrate</goal>
</goals>
<configuration>
<url>jdbc:mysql://localhost:3306/schema2</url>
<user>root</user>
<password>root</password>
<locations>
<location>
filesystem:/path/to/migrations/folder
</location>
</locations>
</configuration>
</execution>
<execution>
<id>second-execution</id>
<phase>compile</phase> <!--whatever phase you need-->
<goals>
<goal>migrate</goal>
</goals>
<configuration>
<url>jdbc:mysql://localhost:3306/schema1</url>
<user>root</user>
<password>root</password>
<locations>
<location>
filesystem:/path/to/other/migrations/folder
</location>
</locations>
</configuration>
</execution>
</executions>
<dependencies>
<dependency>
<groupId>mysql</groupId>
<artifactId>mysql-connector-java</artifactId>
<version>5.1.21</version>
</dependency>
</dependencies>
</plugin>
您可以使用’location’属性来定义要为每个模式运行的迁移，就像在上面的示例中所做的一样。位置类型由其前缀确定。无前缀的位置或以classpath开头的位置：指向classpath上的包，并且可能包含基于sql和基于Java的迁移。以文件系统开头的位置：指向文件系统上的目录，并且只能包含sql迁移。
