MySQLデータベースを使用するSpring3MVCアプリを構築しており、最近、データベースの移行を管理するソリューションにFlywayを統合しました。アプリケーションの起動時にFlywayが最新バージョンに移行するように、 Flywayのドキュメントに従ってapplicationContext.xmlを正常に構成しました。

Flywayをユニット/機能テストでうまく動作させるのに問題があります。データアクセス層にSpringDataJPAを使用しており、いくつかのカスタムクエリをテストするためにいくつかのJUnitテストを構築しました。

これらのテストに使用するアプリケーション構成は次のとおりです。

<jdbc:embedded-database id="dataSource" type="H2" />

<bean id="dataSource" class="org.springframework.jdbc.datasource.DriverManagerDataSource" >
  <property name="driverClassName" value="org.h2.Driver"/>
  <property name="url" value="jdbc:h2:mem:medical_claims_tracker;DB_CLOSE_ON_EXIT=FALSE;DB_CLOSE_DELAY=-1;MODE=MySQL;INIT=CREATE SCHEMA IF NOT EXISTS medical_claims_tracker" />
</bean>

<bean id="flyway" class="com.googlecode.flyway.core.Flyway" init-method="migrate">
    <property name="dataSource" ref="dataSource"/>
    <property name="schemas" value="medical_claims_tracker"/>
    <property name="sqlMigrationPrefix" value="Migration_"/>
</bean>

単体テストを（EclipseまたはMavenを使用して）実行すると、次の例外が発生します。

Medical_claims_trackerというスキーマを使用したいという事実をH2データベースに認識させる方法がわかりません。この回答を使用して、さまざまな接続URLを試すことができ、この回答を使用して、テスト中に使用するapplicationContextオーバーライドを特定することができました。

H2が最初の作成後、テストを実行する前にスキーマを削除することと関係があるのではないかと思いますが、それでDB_CLOSE_ON_EXIT=FALSE;DB_CLOSE_DELAY=-1;解決できると思いました。興味深いことに、フライウェイBean構成でスキーマの仕様を削除すると、次のようになります。

<bean id="flyway" class="com.googlecode.flyway.core.Flyway" init-method="migrate">
    <property name="dataSource" ref="dataSource"/>
    <property name="sqlMigrationPrefix" value="Migration_"/>
</bean>

したがって、最初の構成では、Flywayはmedical_claims_trackerスキーマにschema_versionテーブルを作成できますが、テストを実行するスキーマを見つけることができませんが、2番目のバージョンでは、「デフォルト」を見つけることさえできません。 "schema_versionテーブルを作成するスキーマ。これは正しいですか、それとも私はこれを間違った方法で取得しましたか？

私がテストしたことから、フライウェイとH2をMySql互換モードで混合しているときにのみ問題全体が発生します（MySqlモードがオフの場合は発生しません）。これは、大文字と小文字の区別の不一致が原因です。

  1. 初期化中の h2 は、デフォルトのスキーマ 'PUBLIC' (大文字!) を作成します。
  2. Flyway がデフォルトのスキーマ名を取得しようとすると、'public' (小文字!) になります。
  3. Flyway が現在のスキーマを「パブリック」(小文字!) に変更しようとすると、エラーがスローされます。flyway スキーマを 'MYSCHEMA' に設定した場合でも、移行プロセスのある時点で、常に 'public' に変更しようとします。

現在開発中のアプリケーションでは、メイン データベースとして MySql を使用し、テスト用に H2 を使用しています。私の回避策には、h2 の初期化中に「パブリック」(小文字!) スキーマを作成することが含まれます。

春のデータソース構成:

<bean id="dataSource" class="org.springframework.jdbc.datasource.DriverManagerDataSource" >
 <property name="driverClassName" value="org.h2.Driver"/>
 <property name="url" value="jdbc:h2:mem:MY_APP;MODE=MySQL;DB_CLOSE_ON_EXIT=FALSE;DB_CLOSE_DELAY=-1;INIT=RUNSCRIPT FROM 'classpath:db/migration/test/init_tests.sql';"/>
 <property name="username" value="sa"/>
 <property name="password" value=""/>
</bean>

init_tests.sql:

CREATE SCHEMA IF NOT EXISTS "public";

美しくはありませんが、機能します-お役に立てば幸いです!

init スクリプトのスキーマ名は引用符で囲むか、Flyway に渡す名前を大文字にする必要があります。

問題は、ステートメント内の識別子publicが小文字で引用符で囲まれていることです。

CREATE TABLE "public"...(...)

引用符で囲まれていない必要があります。

CREATE TABLE public...(...)

または大文字:

CREATE TABLE "PUBLIC"...(...)

H2 がデータベースのメタデータで小文字の「public」を返すのは、データベースの URL で MySQL モードが使用されているためです ( ;MODE=MySQL)。そのため、MySQL モードを使用しないことで問題が解決する場合があります。
