現有PUBLIC模式的飛路

Question

@Configuration 
    @ComponentScan("com.sammy") 
    @EnableTransactionManagement 
    public class DataSourceConfig { 

     @Bean(destroyMethod = "shutdown") 
     public DataSource dataSource(){ 
      EmbeddedDatabaseBuilder databaseBuilder = new EmbeddedDatabaseBuilder(); 
      databaseBuilder.setType(EmbeddedDatabaseType.H2); 
      databaseBuilder.addScript("classpath:db/migration/V1__Create_Books_Table.sql"); 
      databaseBuilder.addScript("classpath:db/migration/V2__Add_Books.sql"); 
      return databaseBuilder.build(); 
     } 

     @Bean(name = "entityManagerFactory") 
     public EntityManagerFactory managerFactory(){ 
      HibernateJpaVendorAdapter vendorAdapter = new HibernateJpaVendorAdapter(); 
      vendorAdapter.setGenerateDdl(true); 

      Properties jpaProperties = new Properties(); 
      jpaProperties.put("hibernate.hbm2ddl.auto", "create-drop"); 
      jpaProperties.put("hibernate.dialect", "org.hibernate.dialect.HSQLDialect"); 

      LocalContainerEntityManagerFactoryBean managerFactoryBean = new LocalContainerEntityManagerFactoryBean(); 
      managerFactoryBean.setDataSource(dataSource()); 
      managerFactoryBean.setPackagesToScan("com.sammy"); 
      managerFactoryBean.setJpaVendorAdapter(vendorAdapter); 
      managerFactoryBean.setJpaProperties(jpaProperties); 
      managerFactoryBean.afterPropertiesSet(); 
      return managerFactoryBean.getObject(); 
     } 

     @Bean 
     public PlatformTransactionManager transactionManager(){ 
      JpaTransactionManager transactionManager = new JpaTransactionManager(); 
      transactionManager.setEntityManagerFactory(managerFactory()); 
      return transactionManager; 
     } 
    } 

以上是我的數據配置類。

buildscript { 

    repositories { 
     jcenter()

flyway{ 
    user = 'sa' 
    schema = ['PUBLIC', 'testdb'] 
    url = 'jdbc:h2:mem:testdb' 
    baselineVersion = 7.0 
    baselineOnMigrate = false 
    baselineDescription = "Base Migration" 
} 

flywayMigrate{ 
    dependsOn flyway 
} 

task wrapper(type :Wrapper){ 
    gradleVersion = '3.4.1' 
} 

我已經得到了build.gradle文件，它試圖在SpringBoot應用程序中配置flyway。我試圖將數據遷移到一個內存中H2數據庫，但不斷收到以下錯誤：

我已經閱讀這裏許多可能的解決方案，但仍然沒有喜悅，甚至讀了官方boxfuse網站進行什麼情理之中的事情，但仍然能夠找到一個解決方案。我的文件位於src/main/resources/db.migration並命名爲V1__Create_Books_Table.sql和V2__Add_Books.sql。我也看到了日誌消息： [main] DEBUG org.flywaydb.core.internal.command.DbSchemas - Schema "PUBLIC" already exists. Skipping schema creation. 任何幫助解決這將是大加讚賞。多謝你們！

我已通過添加application.properties內的彈簧引導飛行用的定義爲flyway.baseline-version，而不是使用boxfuse gradle這個插件解決了這個問題。
