Neo4j Rest读取超时异常

在静止模式下使用Neo4j 1.9和Neo4j的弹簧数据。。在我的应用程序上执行负载测试时，我遇到以下异常

我已经使用Neo4j 1.8成功地完成了这个负载测试场景

这可能与启动服务器时收到的警告有关

WARNING: Max 1024 open files allowed, minimum of 40 000 recommended. See the Neo4j manual.
WARNING! You are using an unsupported Java runtime. Please use JDK 6.

版本之间的配置是否有任何更改？出现这种异常的原因是什么

谢谢。

这可能是因为默认的读取超时为30秒。 您可以使用系统属性org.neo4j.rest.read_timeout对其进行自定义

---

将更改为100秒。如果能够在每个查询中指定它，而不是全局指定它，那就太好了。

您有任何公共代码来复制它吗？这方面有什么变化吗？否则，请遵循下面的建议。您是否有任何公共代码来复制此文件？此文件是否有任何变动？否则，请遵循下面的建议。此属性看起来仅适用于Rest Api。我们可以用neo4j java api在cypher查询中设置read_timeout属性吗？如果可以，请告诉我？这个属性看起来只适用于Rest api。我们可以用neo4j java api在cypher查询中设置read_timeout属性吗？如果可以，请告诉我？
