未设置“ hibernate.dialect”时，对DialectResolutionInfo的访问不能为空

Question

Spring 4.3.4休眠5.1.15 从3休眠到5.1.15，我遇到了这个错误。

正常的应用程序可以启动，但是如果我使用相同的设置运行DBTest，它将无法正常工作。

我在类似的问题上有一些安静的问题，但是我很清楚可能是什么问题

我从休眠结束尝试了不同的配置方式。 https://discourse.hibernate.org/t/hibernateexception-access-to-dialectresolutioninfo-cannot-be-null-when-hibernate-dialect-not-set

<bean id="hibernateSessionFactory" class="org.springframework.orm.hibernate5.LocalSessionFactoryBean">
        <property name="hibernateProperties">
            <value>
                hibernate.id.new_generator_mappings=true
                hibernate.dialect=org.hibernate.dialect.MySQL5Dialect
                hibernate.cache.use_second_level_cache=true
                hibernate.cache.use_query_cache=false
                hibernate.generate_statistics=false
                hibernate.cache.use_structured_entries=true
                hibernate.connection.datasource=java:/onaro_pool
            </value>
        </property>
        <property name="packagesToScan" value="com.company.entity" />
        <property name="dataSource" ref="dataSource" />
    </bean>

<bean id="transactionManager" class="org.springframework.orm.hibernate5.HibernateTransactionManager">
    <property name="sessionFactory" ref="hibernateSessionFactory" />
</bean>


@Bean
    @Lazy
    BasicDataSource initDataSource() {
        BasicDataSource dataSource = new BasicDataSource();
        dataSource.setUrl(this.databasePlatform.getSetupConnectionURL());
        dataSource.setDefaultTransactionIsolation(Connection.TRANSACTION_READ_COMMITTED);
        dataSource.setUsername(ProductProperties.getMysqlRootUser());
        dataSource.setPassword(ProductProperties.getMysqlRootPassword());
        dataSource.setTestOnBorrow(true);
        dataSource.setValidationQuery("SELECT 1");
        return dataSource;
    }

我正在扩展org.springframework.orm.hibernate5.LocalSessionFactoryBean以创建CustomHibernateSesionFactoryBean

@Override
public MetadataSources getMetadataSources() {
    this.metadataSourcesAccessed = true;
    if (this.metadataSources == null) {
        BootstrapServiceRegistryBuilder builder = new BootstrapServiceRegistryBuilder();
        ResourcePatternResolver resourcePatternResolver = (ResourcePatternResolver) getResourceLoader();
        if (resourcePatternResolver != null) {
            builder = builder.applyClassLoader(resourcePatternResolver.getClassLoader()).applyIntegrator(eventListenerIntegrator);
        }
        this.metadataSources = new MetadataSources(builder.build());
    }
    return this.metadataSources;
}

@Override
protected SessionFactory buildSessionFactory(LocalSessionFactoryBuilder sfb) {

    if (!DatabasePlatform.INVENTORY_SCHEMA.equals(DatabasePlatform.DEFAULT_INVENTORY_SCHEMA)) {
        logger.info("Overriding inventory schema name to %s", DatabasePlatform.INVENTORY_SCHEMA);
        Metadata metadata = getMetadataSources().getMetadataBuilder().build();
        Collection<PersistentClass> entityBindings = metadata.getEntityBindings();
        /* do customization */

    }
    return (this.bootstrapExecutor != null ? sfb.buildSessionFactory(this.bootstrapExecutor) : sfb.buildSessionFactory());

}

正常的应用程序启动正常，但是Dbtest无法正常工作，我收到了以下提到的错误。

• 我正在使用spring-core（应用程序中没有显式的Spring Boot）。
• 在寻找类似问题时，我遇到了“ Hibernate可以确定要自动使用的正确方言，但是要做到这一点，它需要与数据库进行实时连接”。我注入了数据源bean，不确定为什么会话工厂不使用它？
• 我正在扩展LocalSessionFactoryBean，我应该扩展其他内容吗？
• 使用该属性显式设置config的最佳位置是什么？ config.setProperty（HIBERNATE_DIALECT_KEY，getDialect（））;

Answer 1

该问题是由于我使用覆盖getMetadataSources的方式造成的。

当我覆盖LocalSessionFactoryBean时，出现此问题。
