在将Spring Boot从1.5升级到2.0之后,我们不断遇到以下异常：
[PersistenceUnit: default] Unable to build Hibernate SessionFactory

我们正在使用多租户系统.租户由数据库中的架构分隔.
我们的实体经理工厂如下所示：
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2.0版中,这一行也是有问题的：
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？
在Spring Boot 2.0中还有其他方法可以实现多租户吗？
解决方法:
是的,getHibernateProperties的方法签名已从1.x版本更改为2.x版本.尝试换行
Map<String, Object> properties = new HashMap<>(jpaProperties.getHibernateProperties(dataSource));
至
Map<String, Object> properties = new HashMap<>(jpaProperties.getHibernateProperties(new HibernateSettings()));
