我有一个正在运行的项目。我添加了将近200个实体，现在出现“创建名称为'entityManagerFactory'的bean时出错”。我没有故意改变其他任何东西。
我正在使用Java风格的配置。
我得到以下内容：
org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'entityManagerFactory' defined in class path resource [org/cru/cloud/management/config/DataConfiguration.class]:

我的DataConfiguration包含：
@Bean
public LocalContainerEntityManagerFactoryBean entityManagerFactory()
{
HibernateJpaVendorAdapter vendorAdapter = new HibernateJpaVendorAdapter();
vendorAdapter.setDatabase(Database.H2);
vendorAdapter.setGenerateDdl(true);
LocalContainerEntityManagerFactoryBean factory = new LocalContainerEntityManagerFactoryBean();
factory.setJpaVendorAdapter(vendorAdapter);
factory.setPackagesToScan("org.cru.cloud.management.core.repository", "org.cru.repository");
factory.setDataSource(dataSource());
return factory;
}
最佳答案
我有一个@Embedded实体，在其引用上需要一个@OneToOne批注。
