Flyway在Spring MVC中沒有選擇遷移文件

Question

我遵循了幾個教程，並配置了用於數據庫初始化的Flyway。

我從MYSQL（沒有數據）採取模式轉儲並命名文件V1__initialSchema.sql。所以這是充滿了特定的創建表，外鍵等由mysql轉儲。

然後，我已經配置了豆：

遷飛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初始化器

@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; 
} 

我打開日誌，我可以看到它是 「跳過」 我INITIALISE文件，我不知道爲什麼。架構尚未創建。

我以前沒有使用Flyway，任何人都可以解釋爲什麼它過濾了我的初始化文件？

AFAIK baselineOnMigrate根據DB中的實際模式創建第一個（V1）版本。只有以下版本才能應用（V1.1，V2，...）。

因此，要麼不使用baselineOnMigrate，但您需要從空數據庫模式開始，或者從（如。）V2開始索引您的版本。
