具有高可用性的嵌入式Neo4j

我在一个POC中使用了最近嵌入的Spring数据Neo4j。它在一台机器上快速工作。在投入生产之前，我想将数据库与应用服务器分离。我配置了三个Neo4j服务器实例和HA代理，并使用Spring数据Neo4j Rest进行连接。但速度最差。每个查询的执行时间超过30秒

我正在考虑使用嵌入HA的Neo4j？有人能给我提供链接/教程，用HA代理在嵌入式模式下配置Spring Data Neo4j吗

我希望有3台neo4j服务器和多台应用服务器。 谢谢

我尝试将其设置如下：

<bean id="graphDatabaseService" class="org.neo4j.kernel.HighlyAvailableGraphDatabase" destroy-method="shutdown" scope="singleton">
        <constructor-arg name="storeDir" index="0" value="data/graph.db" />
         <constructor-arg index="1"> 
                        <map>
                                <entry key="ha.server_id" value="${server.id}"></entry>
                                <entry key="ha.server" value="${ha.server.address}:${ha.server.port}"></entry>
                                <entry key="ha.coordinators" value="${coordinators}"></entry>
                                <entry key="enable_remote_shell" value="port=1331"></entry>
                                <entry key="ha.pull_interval" value="1"></entry>
                        </map>
                </constructor-arg>

    </bean> 

仍然不走运，它会以下面的日志停止

下面是一个关于如何将嵌入式HA的参数传递到

HighlyAvailableGraphDatabase

的示例

<neo4j:config graphDatabaseService="graphDatabaseService" />

<context:property-placeholder 
        location="file:/etc/neo4j-ha.properties" />

<bean id="graphDatabaseService" class="org.neo4j.kernel.HighlyAvailableGraphDatabase"
                destroy-method="shutdown" scope="singleton">
                <constructor-arg index="0" value="${database.path}" />
                <constructor-arg index="1"> 
                        <map>
                                <entry key="ha.server_id" value="${server.id}"></entry>
                                <entry key="ha.server" value="${ha.server.address}:${ha.server.port}"></entry>
                                <entry key="ha.coordinators" value="${coordinators}"></entry>
                                <entry key="enable_remote_shell" value="port=1331"></entry>
                                <entry key="ha.pull_interval" value="1"></entry>
                        </map>
                </constructor-arg>
</bean>

不久前我曾就此写过一篇博文。应该给你想要的。（尽管我决定使用Java配置）

迈克尔，这不管用。更新了跟踪问题。它会在中间停止，然后tomcat不会启动。
