配置Spring數據和嵌入neo4j的錯誤

我正在構建Spring數據和嵌入Neo4j的POC，我遵循Spring數據文檔的配置教程，但是當我嘗試運行該項目時，出現「創建錯誤在ServletContext資源中定義名爲'graphDatabaseService'的bean。配置Spring數據和嵌入neo4j的錯誤

我在我的applicationContext.xml和一些不同版本的Spring Data和Neo4j依賴項上嘗試了一些不同的配置，但都沒有成功，只是出現了不同的錯誤。哪裏不對？

這裏是我的applicationContext.xml中，pom.xml中和堆棧跟蹤：

是否有最新的Neo4j穩定版本（2.0.1）的工作？他們似乎在里程碑版本中添加了第二個構造函數，因此可能會導致模糊。 – tstorms

不，我試過Neo4j 2.0.1和Spring Data的實際（3.0.1）和以前的版本（2.3.5）的里程碑 –

如同EmbeddedGraphDatabase類已棄用（它將隱藏在將來的版本中），已經避免它是一種很好的做法。建立GraphDatabaseSerice的最佳方法是使用GraphDatabaseFactory並在您的情況下使用相關的GraphDatabaseBuilder。如果您想配置您的Java Spring bean的，這是它可能是什麼樣子：

@Configuration 
@ImportResource("applicationContext.xml") 
class SpringConfiguration extends Neo4jConfiguration { 
    @Bean(destroyMethod = "shutdown") 
    public GraphDatabaseService graphDatabaseService() { 
     return new GraphDatabaseFactory().newEmbeddedDatabaseBuilder("db") 
      .setConfig("enable_remote_shell", "true").newGraphDatabase(); 
    } 
}

我意識到setConfig方法我使用的是過時的好，但我不認爲在同等類GraphDatabaseSettings。

如果你想使用這種方法，你必須在你的web.xml中使用AnnotationConfigWebApplicationContext。

如果您希望繼續使用XML配置，有」便利豆：

<bean id="graphDatabaseService" class="org.springframework.data.neo4j.support.GraphDatabaseServiceFactoryBean" 
     destroy-method="shutdown" scope="singleton"> 
    <constructor-arg value="db"/> 
    <constructor-arg> 
     <map> 
      <entry key="enable_remote_shell" value="true"/> 
     </map> 
    </constructor-arg> 
</bean>

我看過這個博客文章，並試過這個例子，但後來我得到了一個不同的錯誤：「無法獲取鎖定存儲鎖定文件：data/graph.db/store_lock。請確保沒有其他進程正在使用此數據庫，並且該目錄是可寫的（即使對於只讀訪問也是必需的）」，至極沒有意義，數據庫目錄是在運行時創建的，因此沒有其他進程正在使用它，並且完全有權寫入目錄及其文件。 –

也請參閱更新後的文章。你得到的異常可能與'WrappingNeoServerBootstrapper'有關。它指的是同一個'graphDatabaseService'嗎？ – tstorms

另外，使用'WrappingNeoServer'類，而不是'WrappingNeoServerBootstrapper'。 – tstorms
