Question

我希望能够为外键设置命名策略，当前键的命名为FK_qsp8qs9j1wbh965jtxfbu2q2u，而我想生成的名称为FK_TABLE1_TABLE2，我编写了以下命名策略：

@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);
    }

}

application.properties

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

似乎无论配置liquibase退回到ImplicitNamingStrategyJpaCompliantImpl并忽略自定义项。

Answer 1

我发现liquibase-hibernate4软件包中没有使用命名策略的参数。

我的解决方案是使用maven-central（3.8）上可用的最新版本的libquibase-hibernate5（从5代替4）：

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

pom.xml中完整的插件定义为：

<!-- 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，我通过从父pom覆盖Spring默认值（在liquibase-core中使用以下属性）将pom.xml升级到了最新版本（3.8.9）：

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

在liquibase.properties中，您可以为命名策略设置两个附加参数来设置referenceUrl：

hibernate.physical_naming_strategy
hibernate.implicit_naming_strategy

示例（我使用自己的命名策略）：

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

Spring Liquibase自定义ImplicitNamingStrategy
