Question

将Spring启动从1.5升级到2.0后，我们不断收到此异常：

[PersistenceUnit: default] Unable to build Hibernate SessionFactory

我们正在使用多租户系统。租户由数据库中的模式分隔。

我们的实体经理工厂看起来像这样：

public LocalContainerEntityManagerFactoryBean entityManagerFactory(DataSource dataSource, MultiTenantConnectionProvider multiTenantConnectionProviderImpl, CurrentTenantIdentifierResolver currentTenantIdentifierResolverImpl) {

    Map<String, Object> properties = new HashMap<>(jpaProperties.getHibernateProperties(dataSource));
    properties.put(Environment.MULTI_TENANT, MultiTenancyStrategy.SCHEMA);
    properties.put(Environment.MULTI_TENANT_CONNECTION_PROVIDER, multiTenantConnectionProviderImpl);
    properties.put(Environment.MULTI_TENANT_IDENTIFIER_RESOLVER, currentTenantIdentifierResolverImpl);

    LocalContainerEntityManagerFactoryBean em = new LocalContainerEntityManagerFactoryBean();
    em.setDataSource(dataSource);
    em.setPackagesToScan("com.nevron.backend");
    em.setJpaVendorAdapter(new HibernateJpaVendorAdapter());
    em.setJpaPropertyMap(properties);

    return em;
}

在版本2.0中，这一行也存在问题：

Map<String, Object> properties = new HashMap<> jpaProperties.getHibernateProperties(dataSource));

因为函数'getHibernateProperties'需要'HibernateSettings'。如何解决这个问题呢？有没有其他方法可以在Spring Boot 2.0中实现多租户？

Answer 1

是的，getHibernateProperties的方法签名已从版本1.x更改为2.x.尝试更改行

Map<String, Object> properties = new HashMap<>(jpaProperties.getHibernateProperties(dataSource));

到

Map<String, Object> properties = new HashMap<>(jpaProperties.getHibernateProperties(new HibernateSettings()));

Answer 2

我将Spring Boot更新为2.0.1（构建快照），现在正在运行。

Answer 3

我知道我参加晚会很晚，但是我的回答可能会帮助正在尝试在多租户环境中切换架构并升级到最新SpringBoot版本的人。

我们需要将HibernateProperties传递给该方法以获取属性，因为getHibernateProperties的签名已从1.x版本更改为2.x版本。（由里佐指出）

@Bean
public LocalContainerEntityManagerFactoryBean entityManagerFactory(DataSource dataSource, 
                                                                   MultiTenantConnectionProvider multiTenantConnectionProviderImpl,
                                                                   CurrentTenantIdentifierResolver currentTenantIdentifierResolverImpl,
                                                                   HibernateProperties hibernateProperties) {

    Map<String, Object> properties = hibernateProperties.determineHibernateProperties(
            jpaProperties.getProperties(), new HibernateSettings());
    properties.put(Environment.MULTI_TENANT, MultiTenancyStrategy.SCHEMA);
    properties.put(Environment.MULTI_TENANT_CONNECTION_PROVIDER, multiTenantConnectionProviderImpl);
    properties.put(Environment.MULTI_TENANT_IDENTIFIER_RESOLVER, currentTenantIdentifierResolverImpl);

    LocalContainerEntityManagerFactoryBean em = new LocalContainerEntityManagerFactoryBean();
    em.setDataSource(dataSource);
    em.setPackagesToScan("com.nevron.backend");
    em.setJpaVendorAdapter(new HibernateJpaVendorAdapter());
    em.setJpaPropertyMap(properties);

    return em;
}

Answer 4

将您的代码更改为：

Map<String, Object> hibernateProps = new LinkedHashMap<>();
hibernateProps.putAll(this.jpaProperties.getProperties());
hibernateProps.put(Environment.MULTI_TENANT, MultiTenancyStrategy.DATABASE);
hibernateProps.put(Environment.MULTI_TENANT_CONNECTION_PROVIDER, multiTenantConnectionProvider);
hibernateProps.put(Environment.MULTI_TENANT_IDENTIFIER_RESOLVER, currentTenantIdentifierResolver);

代码段abobe来自使用Spring Boot 2构建的多租户Web应用程序示例（包含完整的源代码）。Take a look。
