我正在尝试使用Iginte Hibernate L2 Cache开发Spring Boot应用程序。
在启动Spring Boot应用程序之前，请先运行服务器节点。当我尝试运行Spring Boot Application时，出现以下错误：

我认为我必须在初始化EntityManagerFactory之前在Spring Boot Application中开始点火。但是我不知道该如何实现。
谢谢。
答案 0 :(得分：0)
首先，您在addresses中有一个错字：127.0.0.1:47500:47509应该是127.0.0.1:47500..47509。
第二，您有两个选择可将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，或使Hibernate自动启动。
由于您使用的是Spring Boot，并且Ignite总是在Spring上下文中最后一次启动，因此使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，您似乎无法在此处使用基于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ignite_instance_name属性（因为它被grid_config覆盖）和客户端应用程序中的Ignite bean（因为它现在由Hibernate启动）。
答案 1 :(得分：0)
我知道这是旧帖子。但是，让我在这里对这个问题发表看法。
此问题的原因是Spring Boot在Ignite之前凝视。要修复它，我们需要确保Ignite在Spring Boot之前启动。
如果按以下方式更改“ Application.java”，则它应该可以工作。
@SpringBootApplication
public class Application {
public static void main(String[] args) {
IgniteSpringBean igniteSpringBean = new IgniteSpringBean();
igniteSpringBean.setConfiguration(ClientConfigurationFactory.createConfiguration());
SpringApplication.run(Application.class, args);
}
}
