找不到用户类型的属性索引 [英] No property index found for type User

问题描述

我正在尝试在同一项目中将ElasticSearch与MySQL一起使用.我在不同的项目中定义了两个存储库，但总是收到以下错误消息:

I'm trying to use ElasticSearch with MySQL in the same project. I defined two repositories in different project but I always get this error message:

当我只是使用 JpaRepository 时，我没有问题.仅当我添加了扩展 ElasticsearchRepository 的另一个存储库时，我才遇到该问题.JPA和Elastic search的接口定义是在不同的程序包中定义的.我在Spring Data Elasticsearch 1.3.4中使用弹性搜索2.2.1我认为这是配置问题.以下是我正在使用的应用程序配置.你能告诉我我是否缺少什么吗?

When I was just using the JpaRepository I had no problem. I got that issue only when I added another repository that extends ElasticsearchRepository. the interface definition of JPA and Elastic search were defined in different packages. I'm using elastic search 2.2.1 with Spring data elasticsearch 1.3.4 I think it's a configuration issue. below is the application config that I'm using. Would you tell me if I'm missing something:

<!-- Enable annotation driven transaction management -->

我的用户实体被这样声明:

My user entity was declared like this:

@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;

和我的ElasticSearch回购定义如下:

and my ElasticSearch repo was defined like this:

@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> {
}

推荐答案

ElasticsearchRepository has a method named index, there is no harm in that, but since you did put your ElasticSearch Repositories in com.owish.repositories.search package, it would be scanned by Spring Data JPA Scanner:

<jpa:repositories base-package="com.owish.repositories" />

因此，Spring Data JPA将尝试代理您的 UserSearchRepo ，并且在 User 类中找不到任何名为 index 的属性，因此错误:

So, Spring Data JPA would try to proxy your UserSearchRepo and couldn't find any property named index in the User class, hence the error:

找不到类型为User的属性索引！

No property index found for type User!

无论如何，如果将ElasticSearch存储库从 com.owish.repositories 包及其子包中移开，则可以.例如，您可以将您的ElasticSearch存储库移动到 com.owish.search 上，并且也可以:

Anyway, if you move your ElasticSearch Repositories away from com.owish.repositories package and its sub-packages, you would be fine. For example, you can move your ElasticSearch Repositories to com.owish.search and also:

<elasticsearch:repositories base-package="com.owish.search" />

还有一个建议，请尝试为应用程序的每个架构方面定义一个配置.一个用于数据，一个用于Web，一个用于安全，并在每个参数中仅放置相关的配置.在您的与数据访问相关配置中，我没有获得此组件扫描程序的作用:

And a word of advice, try to define one configuration for each architectural aspect of your application, e.g. one for data, one for web, one for security, and put only related configurations in each of them. I did not get the role of this component scanner in your Data Access Related configuration:

<context:component-scan base-package="com.owish." />

也许有必要使您的应用程序启动并运行，但我对此表示怀疑，因为它属于配置.

Maybe it's necessary in order to make your application up and running but i seriously doubt the fact that this belongs to the configuration.
