我正在尝试使用 Iginte Hibernate L2 缓存开发 Spring Boot 应用程序。
在启动 Spring Boot 应用程序之前，我运行我的服务器节点。当我尝试运行 Spring Boot 应用程序时，出现以下错误:

我想我必须在初始化entityManagerFactory之前在Spring Boot应用程序中启动ignite。但我不知道如何才能实现这一目标。
最佳答案
首先，您的地址有一个拼写错误:127.0.0.1:47500:47509应该是127.0.0.1:47500..47509。
其次，您有两种选择将 Hibernate L2 Cache 链接到 Ignite - 在 Hibernate 初始化之前在同一 JVM 中手动启动 Ignite 节点或让 Hibernate 自动启动。
由于您使用的是 Spring Boot，并且 Ignite 始终在 Spring 上下文中最后启动，因此采用第二种方法可能会更容易。
要启用自动 Ignite 启动，您需要将 org.apache.ignite.hibernate.grid_config 属性设置为 Ignite XML 配置的路径。不幸的是，这里似乎不能使用基于Java的配置，只能使用XML。您可以将客户端配置转换为 XML，将其放入 META-INF 下的资源中，例如 META-INF/ignite-client.xml，然后引用它(现在没有 META-INF) - org.apache.ignite.hibernate.grid_config: ignite-client.xml。您还应该删除客户端应用程序中的 ignite_instance_name 属性(因为它被 grid_config 覆盖)和 Ignite bean(因为它现在由 Hibernate 启动)。
关于java - Apache Ignite Hibernate L2 缓存与 Spring Boot，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/53525023/
