你能看到我所做的有什么问题吗？我要在黑暗中试一试，请验证 类“IdentityAccessAppConfig”需要一个identityAccessEntityManagerFactory
@EnableJpaRepositories(entityManagerFactoryRef = "identityAccessEntityManagerFactory", value = "com.package.identityaccess")
@Bean
public LocalContainerEntityManagerFactoryBean identityAccessEntityManagerFactory() throws IOException, SQLException
{
当一个类自己负责创建某个对象时，它如何要求该对象的存在？允许这样做吗？我很感激这个建议，并尝试相应地更改配置，但仍然出现相同的错误。为了回答你的问题，我很确定我在问题中的做法是正确的。
@EnableJpaRepositories(entityManagerFactoryRef = "identityAccessEntityManagerFactory", value = "com.package.identityaccess")
