Question

我的Spring启动应用程序中有两个H2数据库。这些数据库中的每一个都负责不同实体的持久性。

第一个由Flyway初始化，工作正常，但现在我需要初始化其他H2数据库。我想我发现用Flyway初始化多个数据库是不可能的。所以我想手动导入我的schema.sql和data.sql文件

这就是我现在所拥有的：两个单独的DatasourceConfig文件：

第一个数据源配置（注意该数据源如何配置为主数据）：

@Configuration
@Profile({"prod","test"})
@EnableJpaRepositories(
        basePackages = "tracker.repository.h2",
        entityManagerFactoryRef = "h2EntityManager",
        transactionManagerRef = "h2TransactionManager")
public class PrivateH2DatasourceConfig {

    @Autowired
    private Environment env;

    @Bean
    @Primary
    public LocalContainerEntityManagerFactoryBean h2EntityManager() {
        LocalContainerEntityManagerFactoryBean em
                = new LocalContainerEntityManagerFactoryBean();
        em.setDataSource(h2DataSource());
        em.setPackagesToScan(
                new String[]{"tracker.domain.h2"});

        HibernateJpaVendorAdapter vendorAdapter = new HibernateJpaVendorAdapter();
        em.setJpaVendorAdapter(vendorAdapter);
        HashMap<String, Object> properties = new HashMap<>();
        properties.put("hibernate.hbm2ddl.auto",
                env.getProperty("hibernate.hbm2ddl.auto"));
        properties.put("hibernate.dialect",
                env.getProperty("hibernate.dialect"));
        em.setJpaPropertyMap(properties);

        return em;
    }

    @Bean
    @Primary
    public DataSource h2DataSource() {

        DriverManagerDataSource dataSource
                = new DriverManagerDataSource();
        dataSource.setDriverClassName(
                env.getProperty("h2.datasource.driver-class-name"));
        dataSource.setUrl(env.getProperty("h2.datasource.url"));
        dataSource.setUsername(env.getProperty("h2.datasource.data-username"));
        dataSource.setPassword(env.getProperty("h2.datasource.data-password"));

        return dataSource;
    }

    @Bean
    @Primary
    public PlatformTransactionManager h2TransactionManager() {

        JpaTransactionManager transactionManager = new JpaTransactionManager();
        transactionManager.setEntityManagerFactory(h2EntityManager().getObject());
        return transactionManager;
    }

}

第二个H2数据源配置文件：

@Configuration
@Profile("test")
@EnableJpaRepositories(
        basePackages = "tracker.repository.wmx",
        entityManagerFactoryRef = "wmxH2EntityManager",
        transactionManagerRef = "wmxH2TransactionManager")
public class WmxH2DatasourceConfig {

    @Autowired
    private Environment env;

    @Bean
    public LocalContainerEntityManagerFactoryBean wmxH2EntityManager() {
        LocalContainerEntityManagerFactoryBean em
                = new LocalContainerEntityManagerFactoryBean();
        em.setDataSource(wmxH2DataSource());
        em.setPackagesToScan(
                new String[]{"tracker.domain.wmx"});

        HibernateJpaVendorAdapter vendorAdapter = new HibernateJpaVendorAdapter();
        em.setJpaVendorAdapter(vendorAdapter);
        HashMap<String, Object> properties = new HashMap<>();
        properties.put("hibernate.hbm2ddl.auto",
                env.getProperty("hibernate.hbm2ddl.auto"));
        properties.put("hibernate.dialect",
                env.getProperty("hibernate.dialect"));
        em.setJpaPropertyMap(properties);

        return em;
    }

    @Bean
    public DataSource wmxH2DataSource() {

        DriverManagerDataSource dataSource
                = new DriverManagerDataSource();
        dataSource.setDriverClassName(
                env.getProperty("test.h2.datasource.driver-class-name"));
        dataSource.setUrl(env.getProperty("test.h2.datasource.url"));
        dataSource.setUsername(env.getProperty("test.h2.datasource.data-username"));
        dataSource.setPassword(env.getProperty("test.h2.datasource.data-password"));

        return dataSource;
    }

    @Bean
    public PlatformTransactionManager wmxH2TransactionManager() {

        JpaTransactionManager transactionManager = new JpaTransactionManager();
        transactionManager.setEntityManagerFactory(wmxH2EntityManager().getObject());
        return transactionManager;
    }

}

然后我有application.properties：

#can be over ridden by run arguments
spring.profiles.active=test

flyway.baseline-on-migrate=true


## H2
h2.datasource.driver-class-name=org.h2.Driver
h2.datasource.url=jdbc:h2:./data/deliverytracker.h2
h2.datasource.data-username=x
h2.datasource.data-password=xxx


## H2 WMX (Test environment)
test.h2.datasource.driver-class-name=org.h2.Driver
test.h2.datasource.url=jdbc:h2:./data/wmx_test.h2
test.h2.datasource.data-username=x
test.h2.datasource.data-password=xxx
test.h2.datasource.initialize=true
test.h2.datasource.data=classpath:schema-test.sql,classpath:data-test.sql

最后一行是我如何尝试在正确的数据库中导入sql脚本，但它似乎没有做任何事情。创建了第一个（非主要）数据库文件，但它是空的。

Spring Boot：2个内存数据库，第一个由flyway初始化，第二个是手动初始化
