我正在尝试在我的Spring应用程序中向所有存储库添加自定义行为，但我不想使用XML配置，只有像@xxxx这样的弹簧注释。
所以我在互联网上寻找并找到了the documentation。 文档的问题在于它处理JPA（而不是MongoDB），并且步骤4不适用于没有xml注释的spring应用程序。
直接声明自定义工厂的bean
我们怎么做？
所以我不放弃，我在互联网上寻找更深层次，我发现了这个：
www.petrikainulainen.net/programming/solr/spring-data-solr-tutorial-adding-custom-methods-to-all-repositories /
（我无法发布更多2个链接......因为我是新手）
但这次是Solr（没有Mongo）。 有趣的是：
import org.springframework.context.annotation.Configuration;
import org.springframework.data.solr.repository.config.EnableSolrRepositories;
@Configuration
@EnableSolrRepositories(
basePackages = "net.petrikainulainen.spring.datasolr.todo.repository.solr",
repositoryFactoryBeanClass = CustomSolrRepositoryFactoryBean.class
)
public class SolrContext {
//Configuration is omitted.
}
但我的申请仍然无效！ 你可以在github找到所有代码。

答案 0 :(得分：3)
这是因为包结构不一致。 @EnableMongoRepositories的基础包指向fr.exemple.test.repository.global，而存储库定义位于fr.exemple.test.model.repository。由于对存储库的扫描在没有任何结果引导自动配置的情况下返回，此时不知道任何自定义RepositoryFactoryBean定义，启动，在fr.exemple.test Application所在的MyRepositoryFactoryBean上启用存储库。
所以你可以更新你的包结构。
或者通过@Component在您的上下文中注册@EnableMongoRepositories并启用RepositoryFactoryBeanSupport来启动感知{{1}}，以便scanning for {{1}}类型的bean可以获取配置
答案 1 :(得分：1)
当您声明@EnableMongoRepositories时，请查看可用选项。其中之一是：
public abstract Class<?> repositoryFactoryBeanClass
返回要用于每个存储库实例的FactoryBean类。
默认为MongoRepositoryFactoryBean。
返回：
默认：
org.springframework.data.mongodb.repository.support.MongoRepositoryFactoryBean.class
所以即是
@EnableMongoRepositories(repositoryFactoryBeanClass=YourMongoCustomRepositoryFactoryBean.class)
