在现有项目中实施Flyway

标签： java hibernate jpa flyway

我继承了一个使用Spring Boot，Hibernate和PostgreSQL的项目。我即将结束2.0版，并对数据库进行了重大更改。我有一个脚本，可以在生产数据库（快照）上工作，重命名架构和一个表。然后，当我下次运行Java代码时，Hibernate更新现有表（新列）并添加几个新表。另外两个SQL脚本填充了新列，并填充了创建的新表，这些表用于保存以前存储在硬编码的Java常量中的数据。

到目前为止，它们都可以很好地连接在一起，但是我想实现Flyway来自动执行数据库更新。但是，到目前为止，我发现的所有博客等都谈到在临时项目中实现Flyway，而不是将其添加到现有项目中。

到目前为止，我已经实现了Flayway的“正常运行”-我的项目将启动并运行，而不会产生错误。这是来自applcationContext.xml的Flyway配置：

  <!-- Flyway db migration -->
  <bean id="flywayConfiguration" class="org.flywaydb.core.api.configuration.ClassicConfiguration" depends-on="dataSource">
    <property name="dataSource" ref="dataSource"/>
    <property name="schemas">
      <array>
        <value>"radar2"</value>
      </array>
    </property>
    <property name="baselineOnMigrate" value="true"/>
 </bean>

 <bean id="flyway" class="org.flywaydb.core.Flyway" init-method="migrate">
   <constructor-arg ref="flywayConfiguration"/>
 </bean>

并且我已经在默认位置（resources\db\migration）

中建立了一个迁移脚本。

请注意，我已经关闭了Hibernate的Validate and Update选项，因此它不再自动更新数据库。

所以我的问题：

我的迁移脚本未运行。 我错过了什么？

我知道迁移没有运行，因为当我查看flyway_schema_history表时，它只有基线条目，而我的V2_0脚本中的表尚未创建。

V2_0_create_tables.sql 

CREATE TABLE radar2."comment" (
  id serial NOT NULL,
  description varchar(255) NOT NULL,
  photo_name varchar(255) NOT NULL,
  short_desc varchar(255) NOT NULL,
  machine_id serial NOT NULL,
  CONSTRAINT comment_pkey PRIMARY KEY (id)
);

ALTER TABLE radar2."comment" ADD CONSTRAINT fk4vjadovig0ru9qinlq9ov9jd8 FOREIGN KEY (machine_id) REFERENCES radar2.machine(id);

CREATE TABLE radar2.customer (
  id serial NOT NULL,
  uri varchar(255) NOT NULL,
  country_code varchar(255) NOT NULL,
  customer_name varchar(255) NOT NULL,
  email_group varchar(255) NOT NULL,
  CONSTRAINT customer_pkey PRIMARY KEY (id)
);

更新

我尝试了@Jens的建议（在我评论它无济于事后删除），并取消了注释<prop key="hibernate.hbm2ddl.auto">validate</prop>，以便不再对其进行处理并更改了输出：

在javax.persistence.PersistenceException: [PersistenceUnit: default] Unable to build Hibernate SessionFactory上搜索通常会出现数据库错误。但是，如果我注释掉applicationContext.xml中的Flyway代码并取消注释<prop key="hibernate.hbm2ddl.auto">update</prop> l，ine，那么Hibernate将更新我的模式。

所以，我还是很困惑...

新的更新

出于无奈，我从项目中删除了Flyway的所有痕迹，并再次进行了测试，并验证了它仍然可以工作。好极了！ ：）

现在，回到Spring docs。根据他们的说法，我应该能够：

  

要在启动时自动运行Flyway数据库迁移，请将org.flywaydb：flyway-core添加到您的类路径中。

因此，我将Maven依赖项重新添加到了pom.xml文件中，并在Oracle J Developer中打开了“项目属性”对话框。然后，在“库和类路径”选项卡上，单击“添加Jar /目录”，并导航到Maven为我下载的flyway-core-6.1.2.jar文件。

在执行Maven Clean-Package清除旧的二进制文件并重建所有内容之后，我没有编译或生成错误。但是，当我在调试器中运行项目时，得到以下信息：

这是版本兼容性问题吗？我在Spring Docs中看不到有关特定版本的Flyway的任何信息。

这时我在applicationContext.xml文件中没有提到flyway，只是将依赖项添加到pom.xml中。

当我使用Google nested exception is javax.persistence.PersistenceException: [PersistenceUnit: default] Unable to build Hibernate SessionFactory时，大多数点击都集中在无法连接到数据库上，但是我已经证实我上面有一个有效的数据库连接，并且只在我的项目中添加了最少的飞行通道，得到这个错误。我缺少一些配置步骤吗？
