Spring Boot 2.4.7升级至2.6集成Ignite、Tomcat启动报错

运行环境 #

• JDK 11
• Ignite 版本：2.13.0
• Tomcat 版本：9.0.54

故障现象 #

将Spring Boot从2.4.7版本升级到2.6版本后，应用启动失败，先后抛出两类异常：

• 启动阶段抛出java.lang.IllegalStateException: Cannot load configuration class: com.mcafee.gti.cache.config.ignite.IgniteConfig，根因为java.lang.ClassNotFoundException，无法找到Ignite配置类
• 上下文关闭阶段抛出org.springframework.beans.factory.CannotLoadBeanClassException，无法加载名称为tomcatServerCustomizer的Bean对应的类com.mcafee.gti.cache.server.TomcatServerCustomizer，根因同样是ClassNotFoundException
