Question

我使用的是Ignite 2.6，它可以作为独立的Java应用程序很好地运行，但是不能与Spring Boot一起使用。我收到此错误

Ignite 2.6是否支持h2 DB（版本1.4.197），默认情况下在Spring-boot 2中提供

Answer 1

这是一个已知问题：

https://issues.apache.org/jira/browse/IGNITE-8197

Spring Boot父POM文件指定h2.version=1.4.197。我们已经可以通过强制降低gradle文件中的H2来解决此问题（我们使用的是Spring Boot 2.0.2，fwiw）：

ext['h2.version'] = '1.4.196'

Answer 2

尝试一下：

<properties>
    <h2.version>1.4.197</h2.version>
</properties>

将此内容放入pom文件中。 springboot 2.1.6.RELEASE的默认值为1.4.199，这会引起问题。

点燃不会从spring-boot 2.0.5开始-h2属性NESTED_JOINS不存在
