1、新建 maven 文件

在 pom.xml 文件中添加如下依赖，基本的 jar 包都存在了，如果需要引入别的 jar 包，可以自行添加。

<dependencies>
    <!-- https://mvnrepository.com/artifact/org.springframework/spring-context -->
    <dependency>
      <groupId>org.springframework</groupId>

      <artifactId>pagehelper</artifactId>
      <version>5.0.0</version>
    </dependency>
  </dependencies>

2、创建配置文件

首先在WEB-INF下的web.xml文件中添加啊如下配置

<?xml version="1.0" encoding="UTF-8"?>
<web-app version="3.0" xmlns="http://java.sun.com/xml/ns/javaee"
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd">


    <!--配置spring上下文参数-->
    <context-param>
        <param-name>contextConfigLocation</param-name>
        <param-value>classpath:applicationContext.xml</param-value>
    </context-param>
    <!--配置监听器-->
    <listener>
        <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
    </listener>


    <servlet>
        <servlet-name>springmvc</servlet-name>
        <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
        <init-param>
            <param-name>contextConfigLocation</param-name>
            <param-value>WEB-INF/springmvc</param-value>
        </init-param>
        <load-on-startup>1</load-on-startup>
    </servlet>
    <servlet-mapping>
        <servlet-name>springmvc</servlet-name>
        <url-pattern>/</url-pattern>
    </servlet-mapping>


    <!--使用自带过滤器，解决中文乱码问题-->
    <filter>
        <filter-name>encoding</filter-name>
        <filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>
        <init-param>
            <param-name>encoding</param-name>
            <param-value>utf-8</param-value>
        </init-param>
    </filter>
    <filter-mapping>
        <filter-name>encoding</filter-name>
        <url-pattern>/*</url-pattern>
    </filter-mapping>

    <!--使用Rest风格uri 把页面普通的post转换成delete货put请求-->
    <filter>
        <filter-name>HiddenHttpMethodFilter</filter-name>
        <filter-class>org.springframework.web.filter.HiddenHttpMethodFilter</filter-class>
    </filter>
    <filter-mapping>
        <filter-name>HiddenHttpMethodFilter</filter-name>
        <url-pattern>/*</url-pattern>
    </filter-mapping>
</web-app>

在此配置文件中配置了关于web相关的配置，指定了spring容器的配置文件和springMVC的配置文件，所以先来创建在resources文件夹下的spring容器配置文件 applicationContext.xml配置文件：

<?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:context="http://www.springframework.org/schema/context"
     xmlns:tx="http://www.springframework.org/schema/tx" xmlns:aop="http://www.springframework.org/schema/aop"
     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 http://www.springframework.org/schema/tx https://www.springframework.org/schema/tx/spring-tx.xsd http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop.xsd">


  <context:component-scan base-package="com.ssm.service"></context:component-scan>


  <bean id="dataSource" class="org.springframework.jdbc.datasource.DriverManagerDataSource">
      <property name="driverClassName" value="com.mysql.cj.jdbc.Driver"></property>
      <property name="url" value="jdbc:mysql://localhost:3306/mybatis?useSSL=false"></property>
      <property name="username" value="root"></property>
      <property name="password" value="root"></property>
    </bean>
    
    <!-- 创建SqlSession工厂 -->
  <bean id="factory" class="org.mybatis.spring.SqlSessionFactoryBean">
    <property name="dataSource" ref="dataSource"></property>

    <!--指定mybatis全局配置文件地址-->
    <property name="configLocation" value="classpath:mybatis-config.xml"></property>

    <!--配置mapper.xml文件扫描路径-->
    <property name="mapperLocations" value="classpath:com/ssm/mapper/*.xml"></property>
    </bean>
    
    <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
    <!-- 扫描哪个mapper接口的包 -->
      <property name="basePackage" value="com.ssm.mapper"></property>
      <property name="SqlSessionFactory" ref="factory"></property>
    </bean>

  <!--事务管理器-->
  <bean id="txManage" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
    <property name="dataSource" ref="dataSource"></property>
  </bean>

  <!--声明式事务-->
  <tx:advice id="txAdvice" transaction-manager="txManage">
    <tx:attributes>
      <tx:method name="get*" read-only="true" />
      <tx:method name="*" />
    </tx:attributes>
  </tx:advice>

  <!--配置aop-->
  <aop:config>
    <aop:pointcut id="mypoint" expression="execution(* com.ssm.service..*(..))"></aop:pointcut>
    <aop:advisor advice-ref="txAdvice" pointcut-ref="mypoint"></aop:advisor>
  </aop:config>

  <!--配置可以执行批量插入的sqlsession-->
  <bean id="sqlSession" class="org.mybatis.spring.SqlSessionTemplate">
    <constructor-arg name="sqlSessionFactory" ref="factory"></constructor-arg>
    <constructor-arg name="executorType" value="BATCH"></constructor-arg>
  </bean>
</beans>

创建springMVC配置文件：

<?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"
       xmlns:mvc="http://www.springframework.org/schema/mvc"
       xsi:schemaLocation="http://www.springframework.org/schema/beans
   http://www.springframework.org/schema/beans/spring-beans-2.5.xsd    http://www.springframework.org/schema/context
  http://www.springframework.org/schema/context/spring-context-2.5.xsd http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc.xsd">


<!--扫描注解-->
    <context:component-scan base-package="com.ssm.controller"></context:component-scan>

    <!--注解驱动-->
    <!--相当于配置了HandlerMapping和HandlerAdapter-->
    <mvc:annotation-driven></mvc:annotation-driven>

    <!--将springmvc不能处理的交给tomcat-->
    <mvc:default-servlet-handler></mvc:default-servlet-handler>

    <!--静态资源-->
    <!--<mvc:resources mapping="/js/**" location="/js/"></mvc:resources>-->
    <!--<mvc:resources mapping="/image/**" location="/image/"></mvc:resources>-->
    <!--<mvc:resources mapping="/css/**" location="/css/"></mvc:resources>-->
    <!--<mvc:resources mapping="/file/**" location="/file/"></mvc:resources>-->

    <!--配置视图解析器-->
    <bean id="ViewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver">
        <property name="prefix" value="/WEB-INF/views/"></property>
        <property name="suffix" value=".jsp"></property>
    </bean>

</beans>

在spring容器的配置文件中指定了mybatis全局配置文件地址，所以创建mybatis配置文件，可以不用创建mybatis配置文件，spring容器可以配置相关的配置，此处创建：

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE configuration
        PUBLIC "-//mybatis.org//DTD Config 3.0//EN"
        "http://mybatis.org/dtd/mybatis-3-config.dtd">
<configuration>
    <settings>
        <setting name="mapUnderscoreToCamelCase" value="true"/>
    </settings>
    <typeAliases>
        <package name="com.ssm.pojo"></package>
    </typeAliases>
    <plugins>
        <plugin interceptor="com.github.pagehelper.PageInterceptor">
            <property name="reasonable" value="true"></property>
        </plugin>
    </plugins>
</configuration>

3、配置完成后的目录结构
