「Spring」DispatcherServletがコントローラを割り当てる方法
構文
DispatcherServlet 変数名= new DispatcherServlet(xxx);
変数名.addServlet(xxx,xxx)
サンプルコード
public class TestWebApplicationInitializer implements WebApplicationInitializer { @Override public void onStartup(ServletContext servletContext) { // web application配置を読む AnnotationConfigWebApplicationContext context = new AnnotationConfigWebApplicationContext(); context.register(AppConfig.class); // DispatcherServlet作成と登録 DispatcherServlet servlet = new DispatcherServlet(context); ServletRegistration.Dynamic registration = servletContext.addServlet("user", servlet); registration.setLoadOnStartup(1); registration.addMapping("/user/*"); } }
web.xmlの定義
<web-app> <listener> <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> </listener> <context-param> <param-name>contextConfigLocation</param-name> <param-value>/WEB-INF/app-context.xml</param-value> </context-param> <servlet> <servlet-name>user</servlet-name> <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class> <init-param> <param-name>contextConfigLocation</param-name> <param-value></param-value> </init-param> <load-on-startup>1</load-on-startup> </servlet> <servlet-mapping> <servlet-name>user</servlet-name> <url-pattern>/user/*</url-pattern> </servlet-mapping> </web-app>
