Flyway-maven-plugin如何从Spring Boot application.yml中读取设置

Question

In my Spring Boot project I want to use flyway-maven-plugin. My pom:

        <plugin>
            <groupId>org.flywaydb</groupId>
            <artifactId>flyway-maven-plugin</artifactId>
            <version>3.1</version>
            <configuration>
                <url>jdbc:mysql://localhost:3306/my_database?autoReconnect=true&amp;useUnicode=true&amp;characterEncoding=UTF-8&amp;connectionCollation=utf8_unicode_ci&amp;characterSetResults=UTF-8</url>
                <user>root</user>
                <password>${spring.datasource.password}</password>
            </configuration>
        </plugin>

And here is my application.yml

spring:
  profiles.active: default
---
spring:
  profiles: default
spring.datasource:
  password: root

As I understood to use mvn flyway:info I need some plugin which will read my application.yml. Or maybe there is another way?

Answer 1

My understanding is that if you are using Flyway with Spring Boot you do not use the flyway-maven plugin.

EDIT: Using Flyway CLI has a place when you need to work with the DB directly to make modifications to Flyway's schema table. An example would be to init an existing DB or clean a test project.

These are the current settings that can be performed out of the box by setting properties within the application.properties for Flyway.

# FLYWAY (FlywayProperties)
flyway.check-location=false # check that migration scripts location exists
flyway.locations=classpath:db/migration # locations of migrations scripts
flyway.schemas= # schemas to update
flyway.init-version= 1 # version to start migration
flyway.init-sqls= # SQL statements to execute to initialize a connection immediately after obtaining it
flyway.sql-migration-prefix=V
flyway.sql-migration-suffix=.sql
flyway.enabled=true
flyway.url= # JDBC url if you want Flyway to create its own DataSource
flyway.user= # JDBC username if you want Flyway to create its own DataSource
flyway.password= # JDBC password if you want Flyway to create its own DataSource

YAML version:

flyway:
    check-location: false
    locations: classpath:db/migration
    ....

If you need further customization you may need to write a @Bean to further customize how Flyway interacts with your application.

I have the following in my src/main/resources/application.properties

flyway.url=jdbc:sqlserver://localhost:1433
flyway.user=james_hetfield
flyway.password=MetaLLic@

spring.datasource.url=${flyway.url}
spring.datasource.user=${flyway.user}
spring.datasource.password=${flyway.password}

And then I run the migrations from the command-line as follows

mvn -Dflyway.configFiles=src/main/resources/application.properties flyway:migrate

要从pom读取*.yml属性，您应该使用https://github.com/aadnk/yaml-properties-plugin
