我正在尝试在 Neo4j Graph DB 中创建一个示例节点，但在启动 tomcat 时出现异常。我正在使用 Neo4j+HA+Spring Data Graph Repository 创建一个节点。我确定我的配置方式有问题。我越来越低于异常。我的所有 3 个 neo4j 集群都已配置并启动。我使用了Neo4j HA Conf Tutorial链接中指定的精确配置
如果您希望我粘贴任何其他代码/类，请告诉我。
我看到下面的异常。
Could not instantiate bean class [org.neo4j.kernel.HighlyAvailableGraphDatabase]:
Constructor threw exception; nested exception is java.lang.IllegalArgumentException:
Missing mandatory setting 'ha.initial_hosts'
以下是完整的例外。
