public abstract class SpringBootServletInitializer
extends SpringBootServletInitializer

An opinionated WebApplicationInitializer to run a SpringApplication from a traditional WAR deployment. Binds Servlet, Filter and ServletContextInitializer beans from the application context to the servlet container.

To configure the application either override the SpringBootServletInitializer.configure(SpringApplicationBuilder) method (calling SpringApplicationBuilder.sources(Object...)) or make the initializer itself a @Configuration. If you are using SpringBootServletInitializer in combination with other WebApplicationInitializers you might also want to add an @Ordered annotation to configure a specific startup order.

Note that a WebApplicationInitializer is only needed if you are building a war file and deploying it. If you prefer to run an embedded container then you won't need this at all.
