我有一个包含 4 个 Neo4j 实例（v.1.9.3）的集群，具有以下 initial_host： 

ha.initial_hosts=192.168.1.10:5001,192.168.1.10:5002,192.168.1.10:5003,192.168.1.10:5004

我正在将此集群用于我的一个 spring 应用程序（使用 Spring-data-neo4j），为此我在 applicationContext 文件中保留了以下配置： 

<bean id="graphDatabaseService" class="org.neo4j.kernel.HighlyAvailableGraphDatabase"
    destroy-method="shutdown" scope="singleton"> 
    <constructor-arg name="storeDir" index="0" value="E:/Neo4J Enterprise Edition/db1/data/graph.db" />
    <constructor-arg index="1">
        <map>
            <entry key="ha.server_id" value="5" />
            <entry key="ha.pull_interval" value="10" />
            <entry key="ha.server" value="192.168.1.10:6005" />
            <entry key="ha.initial_hosts" value="192.168.1.10:5001,192.168.1.10:5002,192.168.1.10:5003,192.168.1.10:5004" />
        </map>
    </constructor-arg>
</bean><neo4j:config graphDatabaseService="graphDatabaseService" />

集群运行正常，实例之间的数据正确同步/复制。

现在是否可以共享集群或在同一个集群上运行另一个应用程序？
为了实现这一点，我为第二个应用程序编写了另一个配置，如下所示： 

<bean id="graphDatabaseService" class="org.neo4j.kernel.HighlyAvailableGraphDatabase"
        destroy-method="shutdown" scope="singleton"> 
        <constructor-arg name="storeDir" index="1" value="E:/db_5/graph.db" />
        <constructor-arg index="2">
            <map>
                <entry key="ha.server_id" value="6" />
                <entry key="ha.pull_interval" value="10" />
                <entry key="ha.server" value="192.168.1.10:6006" />
                <entry key="ha.initial_hosts" value="192.168.1.10:5001,192.168.1.10:5002,192.168.1.10:5003,192.168.1.10:5004" />
            </map>
        </constructor-arg>
    </bean>
    <neo4j:config graphDatabaseService="graphDatabaseService" />

但它总是以异常告终。以下是它的几行：

第二个配置有什么问题吗？我访问了这个链接。并尝试更改ha.server_id和ha.server输入密钥并在同一域的两台不同机器上运行项目，但没有帮助。

谁能指出我在这里做错了什么？谢谢
