Question

我已经按照一些教程并配置了Flyway进行数据库初始化。

我从MYSQL（无数据）中获取了一个模式转储，并将文件命名为V1__initialSchema.sql。所以这里充满了mysql转储的特定create table，foreign key等。

然后我配置了bean：

Flyway Initiailser

@Bean(initMethod = "migrate")
protected Flyway flyway() {
    Flyway flyway = new Flyway();
    flyway.setBaselineOnMigrate(true);
    //flyway.setLocations("classpath:db/migration");
    flyway.setDataSource(dataSource());

    return flyway;
}

JPA Initialiser

@Bean
@DependsOn(value = "flyway")
public LocalContainerEntityManagerFactoryBean entityManagerFactory() {
    LocalContainerEntityManagerFactoryBean factory = new LocalContainerEntityManagerFactoryBean();
    HibernateJpaVendorAdapter vendorAdapter = new HibernateJpaVendorAdapter();
    factory.setDataSource(dataSource());
    factory.setJpaVendorAdapter(vendorAdapter);
    factory.setPackagesToScan("com.ideafactory.mvc", "com.ideafactory.plugins");


    Properties jpaProperties = new Properties();
    jpaProperties.put("hibernate.dialect", "org.hibernate.dialect.MySQLDialect");
    //jpaProperties.put("hibernate.hbm2ddl.auto","create-drop");
    jpaProperties.put("hibernate.show_sql", false);
    jpaProperties.put("hibernate.format_sql", false);
    jpaProperties.put("hibernate.use_sql_comments", false);
    jpaProperties.put("hibnerate.connection.CharSet", "utf8");
    jpaProperties.put("hibernate.connect.characterEncoding", "utf8");
    jpaProperties.put("hibernate.connection.useUnicode", true);

    jpaProperties.put("jadira.usertype.autoRegisterUserTypes", true);

    factory.setJpaProperties(jpaProperties);
    factory.afterPropertiesSet();
    factory.setLoadTimeWeaver(new InstrumentationLoadTimeWeaver());
    return factory;
}

我打开了日志记录，我可以看到它是＆＃34;跳过＆＃34;我的初始文件，我不知道为什么。架构尚未创建。

我之前没有使用过Flyway，有人可以解释为什么它会过滤掉我的初始化文件吗？

Answer 1

AFAIK baselineOnMigrate根据您在DB中的实际架构创建第一个（V1）版本。只有以下版本才会被应用（V1.1，V2，...）。

所以要么不使用baselineOnMigrate，要么你需要从空数据库模式开始，或者从（例如）V2开始索引你的版本。

Flyway没有在Spring MVC中获取迁移文件
