如何在 Spring 引导应用程序中的同一域 class 上同时使用 Spring Data JPA 和 Spring Data Elasticsearch 存储库？

Question

我正在尝试在同一个域对象上同时使用 Spring Data JPA 和 Spring Data Elasticsearch，但它不起作用。

当我尝试运行一个简单的测试时，我遇到了以下异常：

org.springframework.data.mapping.PropertyReferenceException: No property index found for type Person! at org.springframework.data.mapping.PropertyPath.(PropertyPath.java:75) ~[spring-data-commons-1.11.0.RELEASE.jar:na] at org.springframework.data.mapping.PropertyPath.create(PropertyPath.java:327) ~[spring-data-commons-1.11.0.RELEASE.jar:na] at org.springframework.data.mapping.PropertyPath.create(PropertyPath.java:307) ~[spring-data-commons-1.11.0.RELEASE.jar:na] at org.springframework.data.mapping.PropertyPath.from(PropertyPath.java:270) ~[spring-data-commons-1.11.0.RELEASE.jar:na] at org.springframework.data.mapping.PropertyPath.from(PropertyPath.java:241) ~[spring-data-commons-1.11.0.RELEASE.jar:na] at org.springframework.data.repository.query.parser.Part.(Part.java:76) ~[spring-data-commons-1.11.0.RELEASE.jar:na] at org.springframework.data.repository.query.parser.PartTree$OrPart.(PartTree.java:235) ~[spring-data-commons-1.11.0.RELEASE.jar:na] at org.springframework.data.repository.query.parser.PartTree$Predicate.buildTree(PartTree.java:373) ~[spring-data-commons-1.11.0.RELEASE.jar:na] at org.springframework.data.repository.query.parser.PartTree$Predicate.(PartTree.java:353) ~[spring-data-commons-1.11.0.RELEASE.jar:na] at org.springframework.data.repository.query.parser.PartTree.(PartTree.java:84) ~[spring-data-commons-1.11.0.RELEASE.jar:na] at org.springframework.data.jpa.repository.query.PartTreeJpaQuery.(PartTreeJpaQuery.java:61) ~[spring-data-jpa-1.9.0.RELEASE.jar:na] at org.springframework.data.jpa.repository.query.JpaQueryLookupStrategy$CreateQueryLookupStrategy.resolveQuery(JpaQueryLookupStrategy.java:95) ~[spring-data-jpa-1.9.0.RELEASE.jar:na] at org.springframework.data.jpa.repository.query.JpaQueryLookupStrategy$CreateIfNotFoundQueryLookupStrategy.resolveQuery(JpaQueryLookupStrategy.java:206) ~[spring-data-jpa-1.9.0.RELEASE.jar:na] at org.springframework.data.jpa.repository.query.JpaQueryLookupStrategy$AbstractQueryLookupStrategy.resolveQuery(JpaQueryLookupStrategy.java:73) ~[spring-data-jpa-1.9.0.RELEASE.jar:na] at org.springframework.data.repository.core.support.RepositoryFactorySupport$QueryExecutorMethodInterceptor.(RepositoryFactorySupport.java:408) ~[spring-data-commons-1.11.0.RELEASE.jar:na] at org.springframework.data.repository.core.support.RepositoryFactorySupport.getRepository(RepositoryFactorySupport.java:206) ~[spring-data-commons-1.11.0.RELEASE.jar:na] at org.springframework.data.repository.core.support.RepositoryFactoryBeanSupport.initAndReturn(RepositoryFactoryBeanSupport.java:251) ~[spring-data-commons-1.11.0.RELEASE.jar:na] at org.springframework.data.repository.core.support.RepositoryFactoryBeanSupport.afterPropertiesSet(RepositoryFactoryBeanSupport.java:237) ~[spring-data-commons-1.11.0.RELEASE.jar:na] at org.springframework.data.jpa.repository.support.JpaRepositoryFactoryBean.afterPropertiesSet(JpaRepositoryFactoryBean.java:92) ~[spring-data-jpa-1.9.0.RELEASE.jar:na] at org.springframework.beans.factory.support.AbstractAutowireCapableBeanFactory.invokeInitMethods(AbstractAutowireCapableBeanFactory.java:1637) ~[spring-beans-4.2.1.RELEASE.jar:4.2.1.RELEASE] at org.springframework.beans.factory.support.AbstractAutowireCapableBeanFactory.initializeBean(AbstractAutowireCapableBeanFactory.java:1574) ~[spring-beans-4.2.1.RELEASE.jar:4.2.1.RELEASE] ... 43 common frames omitted

它们在禁用任何一个时都有效。

项目基于SpringBoot 1.3.0.M5.

这是一个重现情况的示例项目：

Answer 1

Spring 中的存储库数据与数据源无关，这意味着 JpaRepository 和 ElasticsearchRepository 都汇总到 Repository 界面中。在这种情况下，Spring 引导的自动配置将导致 Spring Data JPA 尝试为项目中继承任何 Spring Data Commons 基础存储库的每个存储库配置一个 bean .

要解决此问题，您需要将 JPA 存储库和 Elasticsearch 存储库移动到单独的包中，并确保使用以下内容注释您的 @SpringBootApplication 应用程序 class：

@EnableJpaRepositories
@EnableElasticsearchRepositories

然后您需要为每个启用注释指定存储库的位置。这最终看起来像：

@SpringBootApplication
@EnableJpaRepositories("com.izeye.throwaway.data")
@EnableElasticsearchRepositories("com.izeye.throwaway.indexing")
public class Application {

    public static void main(String[] args) {
        SpringApplication.run(Application.class, args);
    }

}

然后您的应用程序将能够区分哪些存储库用于哪个 Spring 数据项目。

你可以这样使用：

@Configuration
@EnableTransactionManagement
@EnableJpaRepositories(excludeFilters = @ComponentScan.Filter(type = FilterType.ASSIGNABLE_TYPE, value = ElasticsearchCrudRepository.class))
@EnableElasticsearchRepositories(includeFilters = @ComponentScan.Filter(type = FilterType.ASSIGNABLE_TYPE, value = ElasticsearchCrudRepository.class))
public class DataConfiguration {
    ...
}

或者在SpringBoot中：

@SpringBootApplication
@EnableJpaRepositories(excludeFilters = @ComponentScan.Filter(type = FilterType.ASSIGNABLE_TYPE, value = ElasticsearchCrudRepository.class))
@EnableElasticsearchRepositories(includeFilters = @ComponentScan.Filter(type = FilterType.ASSIGNABLE_TYPE, value = ElasticsearchCrudRepository.class))
public class MyApplication {
    ...
}

如何在 Spring 引导应用程序中的同一域 class 上同时使用 Spring Data JPA 和 Spring Data Elasticsearch 存储库？

How do you use both Spring Data JPA and Spring Data Elasticsearch repositories on the same domain class in a Spring Boot application?

spring-boot

spring-data

spring-data-jpa

spring-data-elasticsearch
