Spring liquibase 自定義 ImplicitNamingStrategy

Question

我希望能夠為外鍵設置命名策略，當前鍵命名為FK_qsp8qs9j1wbh965jtxfbu2q2u並且我想生成像FK_TABLE1_TABLE2這樣的名稱我編寫了以下命名策略：

@Component
public class CustomImplicitNamingStrategy extends SpringImplicitNamingStrategy {

    @Override
    public Identifier determineForeignKeyName(ImplicitForeignKeyNameSource source) {
        Identifier userProvidedIdentifier = source.getUserProvidedIdentifier();

        if (userProvidedIdentifier != null) {
            return userProvidedIdentifier;
        }
        String foreignKey = format("FK_%s_%s", source.getTableName().getText(), source.getReferencedTableName().getText());

        return Identifier.toIdentifier(foreignKey);
    }

}

應用程序屬性

spring.jpa.hibernate.naming.implicit-strategy=foo.bar.CustomImplicitNamingStrategy 

liquibase.properties

referenceUrl=hibernate:spring:foo.bar.model?dialect=org.hibernate.dialect.Oracle10gDialect&hibernate.physical_naming_strategy=org.springframework.boot.orm.jpa.hibernate.SpringPhysicalNamingStrategy&hibernate.implicit_naming_strategy=foo.bar.CustomImplicitNamingStrategy

pom.xml

似乎無論配置如何，liquibase 都會回退到ImplicitNamingStrategyJpaCompliantImpl並忽略自定義的。

Answer 1

我發現， liquibase-hibernate4包中沒有使用命名策略的參數。

我的解決方案是在 maven-central (3.8) 上可用的最新版本中使用libquibase-hibernate5 （5 而不是 4）：

<dependency>
    <groupId>org.liquibase.ext</groupId>
    <artifactId>liquibase-hibernate5</artifactId>
    <version>3.8</version>
</dependency>

pom.xml完整的插件定義是：

<!-- database migration with liquibase -->
<plugin>
    <groupId>org.liquibase</groupId>
    <artifactId>liquibase-maven-plugin</artifactId>
    <version>3.8.9</version>
    <configuration>
        <propertyFileWillOverride>true</propertyFileWillOverride>
        <propertyFile>src/main/resources/db/liquibase.properties</propertyFile>
        <diffChangeLogFile>src/main/resources/db/changes/${maven.build.timestamp}_changelog.xml</diffChangeLogFile>
        <verbose>true</verbose>
        <logging>debug</logging>
    </configuration>
    <dependencies>
        <dependency>
            <groupId>org.liquibase.ext</groupId>
            <artifactId>liquibase-hibernate5</artifactId>
            <version>3.8</version>
        </dependency>
        <dependency>
            <groupId>org.javassist</groupId>
            <artifactId>javassist</artifactId>
            <version>3.20.0-GA</version>
        </dependency>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-data-jpa</artifactId>
            <version>2.1.9.RELEASE</version>
        </dependency>
        <dependency>
            <groupId>de.meisterbohne.framework</groupId>
            <artifactId>meisterbohne-spring-base</artifactId>
            <version>1.0.3</version>
        </dependency>
    </dependencies>
</plugin>

此外，我將liquibase-core升級到最新版本 (3.8.9)，通過覆蓋父 pom 中的 Spring 默認值，在pom.xml具有以下屬性：

<properties>
    <liquibase.version>3.8.9</liquibase.version>
</properties>

在liquibase.properties您可以使用命名策略的兩個附加參數設置referenceUrl ：

• hibernate.physical_naming_strategy
• hibernate.implicit_naming_strategy

示例（我使用我們自己的命名策略）：

referenceUrl=hibernate:spring:\
de.meisterbohne.dms,\
de.meisterbohne.framework.spring\
?dialect=org.hibernate.dialect.MySQL5InnoDBDialect\
&hibernate.physical_naming_strategy=de.meisterbohne.framework.spring.common.data.names.MeisterbohnePhysicalNamingStrategy\
&hibernate.implicit_naming_strategy=de.meisterbohne.framework.spring.common.data.names.MeisterbohneImplicitNamingStrategy
