Flyway 未在 Spring MVC 中获取迁移文件

Question

我遵循了一些教程并为数据库初始化配置了 Flyway。

我从 MYSQL（无数据）中获取了模式转储并将文件命名为 V1__initialSchema.sql。所以这充满了特定的创建 table、外键等，由 mysql.

转储

然后我配置了 bean：

Flyway 初始服务器

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

    return flyway;
}

JPA 初始化程序

@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 "skipping" 我的初始化文件，我不确定为什么。架构尚未创建。

我以前没有用过Flyway，谁能解释一下为什么它过滤掉了我的初始化文件？

Answer 1

AFAIK baselineOnMigrate 从数据库中的实际模式创建第一个 (V1) 版本。并且只会应用以下版本（V1.1、V2、...）。

所以要么不要使用 baselineOnMigrate，但您需要从空数据库模式开始，或者从（例如）V2.

开始为您的版本编制索引
