- - org.springframework.boot.web.servlet.DynamicRegistrationBean<javax.servlet.ServletRegistration.Dynamic>
  - - org.springframework.boot.web.servlet.ServletRegistrationBean<T>

Type Parameters:
T - the type of the Servlet to register
All Implemented Interfaces:
ServletContextInitializer, org.springframework.core.Ordered
```
public class ServletRegistrationBean<T extends javax.servlet.Servlet>
extends DynamicRegistrationBean<javax.servlet.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(javax.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

- Constructor Detail
  - ServletRegistrationBean
```
public ServletRegistrationBean()
```
    Create a new ServletRegistrationBean instance.
  - ServletRegistrationBean
```
public ServletRegistrationBean(T servlet,
                               String... urlMappings)
```
    Create a new ServletRegistrationBean instance with the specified Servlet and URL mappings.
    Parameters:
    servlet - the servlet being mapped
    urlMappings - the URLs being mapped
  - ServletRegistrationBean
```
public ServletRegistrationBean(T servlet,
                               boolean alwaysMapUrl,
                               String... urlMappings)
```
    Create a new ServletRegistrationBean instance with the specified Servlet and URL mappings.
    Parameters:
    servlet - the servlet being mapped
    alwaysMapUrl - if omitted URL mappings should be replaced with '/*'
    urlMappings - the URLs being mapped
- Method Detail
