尚未定义任何SpringApplication源。重写configure方法或添加@Configuration注释

在Weblogic Server 12.2.1上部署SpringBoot Web应用程序时遇到困难

weblogic.application.ModuleException: java.lang.IllegalStateException: No SpringApplication sources have been defined. Either override the configure method or add an @Configuration annotation

我不知道为什么，但是Weblogic的一些版本要求，在使用@springbootsapplication的配置类中，显式实现WebApplicationInitializer，并覆盖springbootservletionInitializer的configure方法，如下所示：

@SpringBootApplication
public class AppConfig extends SpringBootServletInitializer implements WebApplicationInitializer {

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

请调查一下。。。。当我们在WebLogic部署战争时，它就来了。你找到解决方案了吗？
