Class SpringBootServletInitializer

java.lang.Object

org.springframework.boot.context.web.SpringBootServletInitializer

public abstract class SpringBootServletInitializer
extends Object

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 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.
