项目结构

步骤一，创建spring+mybatis项目

参考上一篇博客

步骤二，融入SpringMVC

添加依赖

添加SpringMVC配置文件

xml 复制代码 
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xmlns:p="http://www.springframework.org/schema/p"
       xmlns:context="http://www.springframework.org/schema/context"
       xsi:schemaLocation="
        http://www.springframework.org/schema/beans
        http://www.springframework.org/schema/beans/spring-beans.xsd
        http://www.springframework.org/schema/context
        http://www.springframework.org/schema/context/spring-context.xsd">
    <!-- 1. 配置  需要扫描的控制层在哪个包  -->
    <context:component-scan base-package="com.test.controller"></context:component-scan>

    <!-- 2 配置 视图解析器 中的 前缀和后缀  -->
    <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
        <!-- 设置前缀  -->
        <property name="prefix" value="/WEB-INF/"/>
        <!-- 设置后缀 -->
        <property name="suffix" value=".jsp"/>
    </bean>

</beans>

修改web.xml

xml 复制代码 
<?xml version="1.0" encoding="UTF-8"?>

         id="WebApp_ID" version="3.0">
  <display-name>Archetype Created Web Application</display-name>
  <!-- 配置监听器  读spring的配置文件的 -->
  <!-- 配置spring...xml文件的路径 -->
  <context-param>
    <param-name>contextConfigLocation</param-name>
    <param-value>classpath:applicationContext.xml</param-value>
  </context-param>

  <!-- 配置context 加载的监听器   -->
  <!-- 加载spring 的容器 -->
  <listener>
    <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
  </listener>



  <!-- 配置前端控制器-->
  <servlet>
    <servlet-name>dispatcherServlet</servlet-name>
    <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>

    <init-param>
      <param-name>contextConfigLocation</param-name>
      <param-value>classpath:springmvc.xml</param-value>
    </init-param>

    <load-on-startup>1</load-on-startup>
  </servlet>

  <servlet-mapping>
    <servlet-name>dispatcherServlet</servlet-name>
    <url-pattern>/</url-pattern>
  </servlet-mapping>
</web-app>
