1、首先配置好web.xml  
**`web.xml:文件`**

<?xml version="1.0" encoding="UTF-8"?>
    <web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://xmlns.jcp.org/xml/ns/javaee" xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-app_4_0.xsd" id="WebApp_ID" version="4.0">
        <display-name>MyBatis_first</display-name>
        <welcome-file-list>
            <welcome-file>index.html</welcome-file>
            <welcome-file>index.htm</welcome-file>
            <welcome-file>index.jsp</welcome-file>
            <welcome-file>default.html</welcome-file>
            <welcome-file>default.htm</welcome-file>
            <welcome-file>default.jsp</welcome-file>
        </welcome-file-list>
        
        <context-param>
            <param-name>contextConfigLocation</param-name>
            <param-value>/WEB-INF/applicationContext.xml</param-value>
        </context-param>
        
        <listener>
            <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
        </listener>
        
        <servlet>
            <servlet-name>spring-dispatcher</servlet-name>
            <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
            
            <init-param>
                <param-name>contextConfigLocation</param-name>
                <param-value>WEB-INF/dispatcher-servlet.xml</param-value>
            </init-param>
            <load-on-startup>1</load-on-startup>
        </servlet>
        <servlet-mapping>
            <servlet-name>spring-dispatcher</servlet-name>
            <url-pattern>/</url-pattern>
        </servlet-mapping>
    </web-app>

2、**`applicationContext.xml 文件`**  
该文件中也添加了一些分页的相关配置

<?xml version="1.0" encoding="UTF-8"?>
    <beans xmlns="http://www.springframework.org/schema/beans"
           xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
           xmlns:context="http://www.springframework.org/schema/context"
           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
    ">
    
        
        <context:component-scan base-package="com.gx"></context:component-scan>
    
        
        <context:property-placeholder location="classpath:db.properties"/>
    
        
        <bean id="dataSource" class="com.alibaba.druid.pool.DruidDataSource">
            <property name="driverClassName" value="${database.driver}"></property>
            <property name="url" value="${database.url}"></property>
            <property name="username" value="${database.username}"></property>
            <property name="password" value="${database.password}"></property>
        </bean>
    
        
        <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
            
            <property name="dataSource" ref="dataSource"></property>
            <property name="configLocation" value="classpath:mybatis-config.xml"></property>
            
            <property name="plugins">
                <list>
                    <bean class="com.github.pagehelper.PageInterceptor">
                        <property name="properties">
                            <value>
                                helperDialect=mysql
                                reasonable=true
                            </value>
                        </property>
                    </bean>
                </list>
            </property>
        </bean>
    
        
        <bean id="sqlSession" class="org.mybatis.spring.SqlSessionTemplate">
            <constructor-arg index="0" ref="sqlSessionFactory"></constructor-arg>
        </bean>
    
        
        <bean id="mapperScannerConfigurer" class="org.mybatis.spring.mapper.MapperScannerConfigurer">
            <property name="sqlSessionFactoryBeanName" value="sqlSessionFactory"></property>
            <property name="basePackage" value="com.gx.mapper"></property>
        </bean>
    </beans>

3、`dispatcher-servlet.xml文件`

4、`连接数据库的相关文件db.properties`

database.driver = com.mysql.cj.jdbc.Driver
    database.url= jdbc:mysql://localhost:3306/a_test?characterEncoding=utf-8&&serverTimezone=PRC
    database.username = root
    database.password = root

5、`mybatis-config.xml文件`

<?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>
        <typeAliases>
            
            <package name="vo" />
        </typeAliases>
        <mappers>
            <mapper resource="com/gx/mapper/EmpMapper.xml"></mapper>
        </mappers>
    </configuration>

最后检测一下pom.xml的配置文件的 jar包,(本人的jar包比较多，并非单个配置)  
`pom.xml:`该文件是用来管理jar包的

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