我试图在同一个项目中使用ElasticSearch和MySQL。 我在不同的项目中定义了两个存储库，但我总是收到此错误消息：

当我刚刚使用JpaRepository时我没有问题。
只有当我添加另一个扩展ElasticsearchRepository的存储库时，我才会遇到这个问题。
JPA和Elastic搜索的接口定义在不同的包中定义。
我使用弹性搜索2.2.1与Spring数据弹性搜索1.3.4
我认为这是一个配置问题。
下面是我正在使用的应用程序配置。如果我错过了什么，你能告诉我吗？

我的用户实体声明如下：
@Entity
@Table (name ="user")
@Document(indexName = "user")
public class User {
@Id
@Column (name = "id")
@GeneratedValue (strategy = GenerationType.AUTO)
private long id;
@Column (name = "username", nullable = false)
private String username;
@Column (name = "password", nullable = false)
private String password;
我的ElasticSearch回购定义如下：
@Repository
public interface UserSearchRepo extends ElasticsearchRepository<User, Long> {
User findByUsername(String username);
List<User> findAllByOrderById ();
}
和我的JPA回购
@Repository
public interface UserRepository extends JpaRepository<User, Long> {
}

ElasticsearchRepository有一个名为index的方法，没有任何损害，但是因为你确实将 ElasticSearch存储库放在com.owish.repositories.search包中，它会由 Spring Data JPA扫描仪扫描：
<jpa:repositories base-package="com.owish.repositories" />
因此，Spring Data JPA会尝试代理您的UserSearchRepo，但在index类中找不到任何名为User的属性，因此出现错误：
找不到类型User！
的属性索引
无论如何，如果你将ElasticSearch存储库从com.owish.repositories包及其子包移开，你会没事的。例如，您可以将ElasticSearch存储库移动到com.owish.search以及：
<elasticsearch:repositories base-package="com.owish.search" />
建议，尝试为应用程序的每个体系结构方面定义一个配置，例如：一个用于数据，一个用于Web，一个用于安全性，并且仅在每个中放置相关配置。我没有在数据访问相关配置中获得此组件扫描程序的角色：
<context:component-scan base-package="com.owish." />
为了使您的应用程序正常运行，可能是必要的，但我严重怀疑这属于配置这一事实。

当您仔细阅读错误时，您将了解其原因
线程“main”中的异常org.springframework.beans.factory.BeanCreationException：创建名为'userController'的bean时出错：注入自动连接的依赖项失败;嵌套异常是org.springframework.beans.factory.BeanCreationException：无法自动装配字段：private com.owish.services.UserServices com.owish.controllers.UserController.userServices;嵌套异常是org.springframework.beans.factory.BeanCreationException：创建名为'userServices'的bean时出错：注入自动连接的依赖项失败;嵌套异常是org.springframework.beans.factory.BeanCreationException：无法自动装配字段：private com.owish.repositories.search.UserSearchRepo com.owish.services.UserServices.userSearchRepo;嵌套异常是org.springframework.beans.factory.BeanCreationException：创建名为'userSearchRepo'的bean时出错：init方法的调用失败;嵌套异常是org.springframework.data.mapping.PropertyReferenceException：找不到类型User的属性索引！
所以它的最后一行说没有类型User的属性索引，
这意味着您有一个名为User的类，并且您有一个属性，您可以使用该属性映射名为index的表。
