我有一个正在运作的项目。我添加了将近200个实体，现在我得到了＃34;错误创建名称为＆entityManagerFactory＆＃39;＆＃34;的bean。我并没有故意改变其他任何事情。
我使用的是Java风格的混淆。
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;
}
答案 0 :(得分：4)
我有一个@Embedded实体需要@OneToOne注释。
