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;
    }
