【问题描述】：

（参见下面的堆栈跟踪）我有一个 CrudRepository 正在通过瞬态属性进行查询，它有一个 getter，但没有实际的底层成员变量。在我的服务中，我调用了MyRecordDao.findByMyMemberAttribute()，这是堆栈跟踪的来源。这个失败是弹性搜索特有的，我的其他数据存储没有任何问题。我尝试使用@Primary 注释数据源，使用@EnableElasticsearchRepositories(basePackages='com.myproject.service')，添加@Transient 作为getter 上的注释，这些都不起作用。我无法使用@Field 注释getter，因为该注释只允许在成员变量上使用。创建一个未使用的成员变量并添加该注释也不起作用。

【参考方案1】：

违规类是org.springframework.boot.autoconfigure.data.elasticsearch.ElasticsearchRepositoriesRegistrar，它最终拉入了一个不合格的@EnableElasticsearchRepositories，然后spring-data 尝试通过我的getter 查询Elasticsearch，但失败了。这是由@SpringBootApplication 引入的，您需要将 Application 类上的注释修改为：

@SpringBootApplication(exclude=ElasticsearchRepositoriesAutoConfiguration.class)

到目前为止，我还没有发现任何不利的副作用，但是这个项目很小，所以我不能说很多用例。
