org.springframework.boot.web.servlet.support

Class SpringBootServletInitializer

  • java.lang.Object
    • org.springframework.boot.web.servlet.support.SpringBootServletInitializer
  • All Implemented Interfaces:
    org.springframework.web.WebApplicationInitializer

    public abstract class SpringBootServletInitializer
extends Object
implements org.springframework.web.WebApplicationInitializer
    An opinionated WebApplicationInitializer to run a SpringApplication from a traditional WAR deployment. Binds Servlet, Filter and ServletContextInitializer beans from the application context to the server.

    To configure the application either override the configure(SpringApplicationBuilder) method (calling SpringApplicationBuilder.sources(Class...)) 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 web server then you won't need this at all.

        protected org.springframework.web.context.WebApplicationContext createRootApplicationContext(javax.servlet.ServletContext servletContext)

      • createSpringApplicationBuilder

        protected SpringApplicationBuilder createSpringApplicationBuilder()
        Returns the SpringApplicationBuilder that is used to configure and create the SpringApplication. The default implementation returns a new SpringApplicationBuilder in its default state.

      • run

        protected org.springframework.web.context.WebApplicationContext run(SpringApplication application)
        Called to run a fully configured SpringApplication.
        Parameters:
        application - the application to run
        Returns:
        the WebApplicationContext

      • configure

        protected SpringApplicationBuilder configure(SpringApplicationBuilder builder)
        Configure the application. Normally all you would need to do is to add sources (e.g. config classes) because other settings have sensible defaults. You might choose (for instance) to add default command line arguments, or set an active Spring profile.
        Parameters:
        builder - a builder for the application context
        Returns:
        the application builder
