本文介绍了一个简单的Spring MVC请求处理器实现方法，通过继承AbstractController类并覆盖handleRequestInternal方法来响应HTTP请求。此外，还展示了如何在spring.xml配置文件中定义处理器，并通过supportedMethods属性指定处理器支持的HTTP请求方式。

GIT

POST

HEAD

PUT

CONNECT

DELETE

TRANCE

OPTIONS等等。

创建一个类继承AbstractController类

package cn.happy.day02;

import org.springframework.web.servlet.ModelAndView;
import org.springframework.web.servlet.mvc.AbstractController;
import org.springframework.web.servlet.mvc.Controller;

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;


//处理器类
public class FirstController extends AbstractController {

    protected ModelAndView handleRequestInternal(HttpServletRequest httpServletRequest, HttpServletResponse httpServletResponse) throws Exception {
        ModelAndView mv = new ModelAndView();
        mv.setViewName("index");
        return mv;
    }
}

spring.xml配置

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

    <bean id="/hello" class="cn.happy.day02.FirstController">
        <!--限定请求方式-->
        <property name="supportedMethods" value="GET,POST"/>
    </bean>


</beans>
