我正在开发 spring boot 项目，刚刚升级到 spring boot 2.0.3.RELEASE 版本。
升级后，我遇到以下问题
org.springframework.data.mapping.PropertyReferenceException
我到处搜索，但 PropertyReferenceException 抛出错误，查找类中或任何地方不存在的对象。
我搜索了很多，但找不到解决方案。

如何解决getOne属性不存在的问题？
最佳答案
您似乎在 MyLog.java 中使用了多个 Spring Data 模块:
@Entity // Spring JPA
@Table(name = "my_log")
@Cache(usage = CacheConcurrencyStrategy.NONSTRICT_READ_WRITE)
@Document(indexName = "mylog") // Spring Elasticsearch
public class MyLog implements Serializable {
根据spring documentation ，您必须告诉您的应用程序存储库在哪里:
@EnableJpaRepositories(basePackages = "com.acme.repositories.jpa")
@EnableElasticsearchRepositories(basePackages = "com.acme.repositories.elasticsearch")
interface Configuration { }
