Question

Flyway

一起使用，现在我需要与2个数据库一起使用它，今天这是我的属性文件：

flyway.validateOnMigrate=false
flyway.baselineOnMigrate=true
flyway.check-location=false
flyway.locations=classpath:db/migration
flyway.sql-migration-prefix=V
flyway.sql-migration-suffix=.sql
flyway.enabled=true

因此，如何配置以使用另一个连接（与我的迁移中的另一个DIR）？

您可以手动配置下面的两个数据库。

@Configuraton
public class PrimaryDb {

@Primary
@Bean(name = "primaryDataSourceProperties")
@ConfigurationProperties("spring.datasource-primary")
public DataSourceProperties primaryDataSourceProperties() {
    return new DataSourceProperties();
}

@Primary
@Bean(name = "primaryDataSource")
@ConfigurationProperties("spring.datasource-primary.configuration")
public DataSource primaryDataSource(@Qualifier("primaryDataSourceProperties") DataSourceProperties primaryDataSourceProperties) {
    return primaryDataSourceProperties.initializeDataSourceBuilder().type(HikariDataSource.class).build();
   }
}

对于飞行配置，您需要明确定义每个数据库在应用更改时应寻找的位置。

@Configuration
public class FlywayInit {

@Autowired
private DataSource primaryDb;

@Autowired
@Qualifier("secondaryDataSource")
private DataSource secondaryDb;

@PostConstruct
public void flyway() {
    Flyway flywayP = Flyway.configure().dataSource(primaryDb).locations("db/migration").load();
    Flyway flywayS = Flyway.configure().dataSource(secondaryDb).locations("db/second").load();
    
    flywayP.migrate();
    flywayS.migrate();
  } 
}
