未知的持久性实体错误

【中文标题】未知的持久性实体错误【英文标题】:Unknown persistence entity error 【发布时间】:2015-09-09 13:14:33 【问题描述】:

我目前在生产中使用 SDN 3.0.1,但我希望从 SDN 3.3.0 的最新改进中受益(参见:http://jexp.de/blog/2014/12/spring-data-neo4j-improving-remoting-performance/)。为此,我不得不将我的 grails 项目(使用 Spring 3)迁移到最新的 grails 版本(使用 Spring Boot 和 Spring 4)。

但它没有按预期工作。我在尝试从 Neo4J 2.1.8 服务器获取数据时收到此错误:

Unknown persistent entity com.motards.nous.server.v1.dao.repository.relationship.domain.Ride. Stacktrace follows:

    ... 3 common frames omitted

这是我的 Neo4J 配置:

@Configuration
    @EnableNeo4jRepositories(basePackages = "com.motards.nous.server.v1.dao", repositoryImplementationPostfix = "Repository")
    static class MyNeo4jConfiguration extends Neo4jConfiguration 

        MyNeo4jConfiguration() 
            setBasePackage("com.motards.nous.server.v1.dao")
        

        @Bean
        GraphDatabaseService graphDatabaseService() 
            return new SpringCypherRestGraphDatabase("http://neo4j:7474/db/data")
        

        @Bean
        Neo4jMappingContext neo4jMappingContext() 
            return new Neo4jMappingContext()
        

    

我错过了什么吗?

-- 编辑--

这是我在将实体与存储库分开后更新的配置。

@Configuration
@EnableNeo4jRepositories(basePackages = "com.nousmotards.core.repositories.neo4j", repositoryImplementationPostfix = "Repository")
class MyNeo4jConfiguration extends Neo4jConfiguration 

    @Resource
    Environment environment

    MyNeo4jConfiguration() 
        setBasePackage("com.nousmotards.core.domains.neo4j")
    

    @Bean
    GraphDatabaseService graphDatabaseService() 
        return new SpringCypherRestGraphDatabase("http://$environment.getProperty("nm.neo4j.host"):$environment.getProperty("nm.neo4j.port")/db/data")
    


这是我得到的完整堆栈跟踪: https://gist.github.com/evoxmusic/615ac940186ec97d2e89

-- 编辑 2--

当我添加时

@Bean
    Neo4jMappingContext neo4jMappingContext() 
        return new Neo4jMappingContext()
    

应用程序正常启动,但当我尝试查询 neo4j 实体时出现此错误:

【问题讨论】:

这是适合您的域实体的软件包吗? "com.motards.nous.server.v1.dao" 嗨@MichaelHunger,是的。我已将其更改为单独的存储库和实体,但效果不佳......我现在在同一个项目中使用 spring data redis、mongodb、elasticsearch 和 neo4j ......我将更新帖子,因为我已经改变了这些东西使其符合文档。 我已经编辑了我的帖子,希望你能找出问题所在。 @Transient 是否与 SDN 3.3.0 一起正常工作? 我做了一些测试,似乎SDN不喜欢像“地图”这样的通用...... 【参考方案1】:

所以我发现了问题.. 奇怪的 Spring Data Neo4J... 我不得不将所有“Map”对象更改为“HashMap”之类的具体对象,它现在可以工作了。

好像是个bug……
