引入依赖包

<dependency>
  <groupId>org.springframework</groupId>
  <artifactId>spring-webmvc</artifactId>
  <version>5.2.5.RELEASE</version>

</dependency>


web.xml

<!-- springmvc -->

    <servlet-mapping>
<!--    匹配controller的规则   -->

        <url-pattern>/</url-pattern>
    </servlet-mapping>

</beans>


Controller.java

//@Controller(功能和@Component一样;但他不仅注册了Bean并且将此类设置成了控制器);
@Controller
public class HelloHandler {
    //映射请求地址
    @RequestMapping("/index")
    public String hello(){
        System.out.println("index......");
        //return一个页面名字,由视图解析器解析成物理路径;
        return "index";
    }
}
