SpringMVC的构建：https://blog.csdn.net/young_1004/article/details/82114221
1.在springmvc.xml 中配置注解的处理器映射器
<!--3.1之后注解的处理器映射器-->
<bean class="org.springframework.web.servlet.mvc.method.annotation.RequestMappingHandlerMapping"></bean>2.在springmvc.xml 中配置注解的处理器适配器
<!--3.1之后注解的处理器适配器-->
<bean class="org.springframework.web.servlet.mvc.method.annotation.RequestMappingHandlerAdapter"></bean>
3.配置视图解析器
<!--视图解析器-->
<bean class="org.springframework.web.servlet.view.InternalResourceViewResolver"></bean>4.开启注解扫描器
<context:component-scan base-package="com.uplooking.springmvc"></context:component-scan>5.springmvc.xml
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

<!--处理器映射器-->
<bean class="org.springframework.web.servlet.handler.BeanNameUrlHandlerMapping"></bean>
<!--3.1之后注解的处理器映射器-->
<bean class="org.springframework.web.servlet.mvc.method.annotation.RequestMappingHandlerMapping"></bean>
<!--处理器适配器-->
<bean class="org.springframework.web.servlet.mvc.SimpleControllerHandlerAdapter"></bean>
<!--3.1之后注解的处理器适配器-->
<bean class="org.springframework.web.servlet.mvc.method.annotation.RequestMappingHandlerAdapter"></bean>
<!--视图解析器-->
<bean class="org.springframework.web.servlet.view.InternalResourceViewResolver"></bean>
<!--开启注解扫描器-->
<context:component-scan base-package="com.ma.springmvc"></context:component-scan>
</beans>6.Handler
package com.ma.springmvc.handler;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.servlet.ModelAndView;
@Controller
public class UserController {
@RequestMapping("/findUser")
public ModelAndView findUser(){
ModelAndView modelAndView = new ModelAndView();
modelAndView.setViewName("index.jsp");
modelAndView.addObject("username","User");
return modelAndView;
}
}7.index.jsp
<html>
<body>
<h2>${username}</h2>
</body>
</html>
8.访问
http://localhost:8080/findUser.action
