DispatcherServlet
is an actual Servlet
(it inherits from the HttpServlet
base class)有多种方法可以使得DispatcherServlet能够拦截相应的URL请求(即拦截类似“/example/*”之类的请求)
/** * @author chen * @description 此类用于初始化spring web mvc中的DispatchServlet * 使得"/example/*"之类的url请求可以被dispatchServlet拦截 * */ public class InitializeSpringMVC implements WebApplicationInitializer{ @Override public void onStartup(ServletContext container) { ServletRegistration.Dynamic registration = container.addServlet("example", new DispatcherServlet()); registration.setLoadOnStartup(1); registration.addMapping("/example/*"); } }
In the preceding example, all requests starting with /example
will be handled by the DispatcherServlet
instance named example
.
WebApplicationInitializer
is an interface provided by Spring MVC that ensures your code-based configuration is detected and automatically used to initialize any Servlet 3 container.
An abstract base class implementation of this interface named AbstractAnnotationConfigDispatcherServletInitializer
makes it even easier to register the DispatcherServlet
by simply specifying its servlet mapping and listing configuration classes - it’s even the recommended way to set up your Spring MVC application. See Code-based Servlet container initialization for more details.
<web-app> <servlet> <servlet-name>example</servlet-name> <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class> <load-on-startup>1</load-on-startup> </servlet> <servlet-mapping> <servlet-name>example</servlet-name> <url-pattern>/example/*</url-pattern> </servlet-mapping> </web-app>
In the preceding example, all requests starting with /example
will be handled by the DispatcherServlet
instance named example
.
