我们有一个使用maven配置的
java应用程序,它使用多个数据库.这是一个应用程序 – 许多架构.
我已经配置了flyway,经过测试并且运行良好,但我的配置仅适用于一个数据库.
这是我用一个模式测试的pom.xml：
<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">

<build>
<plugins>

<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,我有以下pom.xml配置了2个架构.
<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">

我执行flyway操作但没有工作,这是我得到的错误：

数据库配置没问题.我还检查了架构是否正常我缺少什么？
更新：我从命令行flyway中删除了：它运行良好.谢谢Jk1
解决方法
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,就像上面的示例中所做的那样.位置类型由其前缀确定.以classpath开头的未加前缀的位置或位置：指向类路径上的包,并且可能包含基于sql和java的迁移.以filesystem开头的位置：指向文件系统上的目录,可能只包含sql迁移.
