基于 Annotation 的 Servlet API

Servlet 是一套用于处理 HTTP 请求的 API 标准
配置: SpringMVC里有接口 WebApplicationInitializer

package com.skyline;
import javax.servlet.*;
import org.springframework.web.WebApplicationInitializer;
import org.springframework.web.servlet.DispatcherServlet;
public class MyWebApplicationInitializer implements WebApplicationInitializer {
    @Override
    public void onStartup(ServletContext container) {
        ServletRegistration.Dynamic registration = container.addServlet("MyFirstServletName", new DispatcherServlet());
        registration.setLoadOnStartup(1);
        registration.addMapping("/");
    }
}

把MyWebApplicationInitializer.class扔到Tomcat目录下就行了
对应

<servlet>
    <servlet-name>MyFirstServletName</servlet-name>
    <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
    <load-on-startup>1</load-on-startup>
</servlet>

<servlet-mapping>
    <servlet-name>MyFirstServletName</servlet-name>
    <url-pattern>/*</url-pattern>
</servlet-mapping>
