Spring Boot WAR包部署WebSphere Liberty成功但无法启动问题

我尝试通过IntelliJ IDEA的WebSphere/Liberty Server运行配置，将Spring Boot应用以WAR包形式部署并运行在WebSphere Liberty 23.0.0.9上。当前使用Java 11和Spring Boot 2.4.5版本，WAR包已成功构建并部署，但Spring Boot应用无法启动。该应用以独立Jar包在Spring Boot内嵌Tomcat上运行无异常，无法确定是Maven依赖、Spring配置还是server.xml中缺失了必要配置。

SpringBootApplication类代码 #

@SpringBootApplication(scanBasePackages = "main.package", exclude = { JmxAutoConfiguration.class })
@EntityScan(basePackages = "main.package.domain.model")
@EnableJpaRepositories(basePackages = "main.package.domain.repository")
public class Application extends SpringBootServletInitializer {

    public static void main(String[] args) {
        SpringApplication.run(Application.class, args);
    }

    @Override
    protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
        return application.sources(Application.class);
    }

}
