我目前正在使用SDN 3.0.1，但我想从SDN 3.3.0的最后一次改进中受益（参见：http://jexp.de/blog/2014/12/spring-data-neo4j-improving-remoting-performance/）。为此我必须将我的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服务器获取数据时遇到此错误：
Unknown persistent entity com.motards.nous.server.v1.dao.repository.relationship.domain.Ride. Stacktrace follows:

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 -
将实体与存储库分开后，我的更新配置。
@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")
}
}
这里是我得到的完整堆栈跟踪： https://gist.github.com/evoxmusic/615ac940186ec97d2e89
- 编辑2 -
当我添加
@Bean
Neo4jMappingContext neo4jMappingContext() {
return new Neo4jMappingContext()
}
应用程序正确启动，但是当我尝试查询neo4j实体时，我收到此错误：

答案 0 :(得分：0)
所以我发现了问题..奇怪的Spring Data Neo4J ...... 我不得不改变所有＆＃34; Map＆＃34;反对像＆＃34; HashMap＆＃34;它现在有效。
似乎是一个错误...
