org.springframework.boot.web.servlet.ServletRegistrationBean<T>

Type Parameters:

T - the type of the Servlet to register

All Implemented Interfaces:

Aware, BeanNameAware, ServletContextInitializer, Ordered

Direct Known Subclasses:

DispatcherServletRegistrationBean

public class ServletRegistrationBean<T extends Servlet>
extends DynamicRegistrationBean<ServletRegistration.Dynamic>

A ServletContextInitializer to register Servlets in a Servlet 3.0+ container. Similar to the registration features provided by ServletContext but with a Spring Bean friendly design.

The servlet must be specified before calling RegistrationBean.onStartup(jakarta.servlet.ServletContext). URL mapping can be configured used setUrlMappings(java.util.Collection<java.lang.String>) or omitted when mapping to '/*' (unless alwaysMapUrl is set to false). The servlet name will be deduced if not specified.

Since:

1.4.0
