先导入项目的相关依赖（IDEA），在整个项目下的pop.xml文件下导入，这样建立的module也会自动添加相关依赖。
pop.xml文件下的相关依赖：

                <filtering>true</filtering>
            </resource>
        </resources>
    </build>

注：中主要是放置放在非resources文件夹下的文件识别不到的问题。
2. 整合Mybatis层，在resources下创建mybatis-config.xml文件。（mybatis配置文件下主要配置日志、扫描接口类、定位实体类的包所在位置等）。

<?xml version="1.0" encoding="UTF8" ?>
<!DOCTYPE configuration
        PUBLIC "-//mybatis.org//DTD Config 3.0//EN"
        "http://mybatis.org/dtd/mybatis-3-config.dtd">
<configuration>
   <!--日志-->
    <settings>
        <setting name="logImpl" value="STDOUT_LOGGING"/>
    </settings>
	<!--扫描实体类的包所在位置-->
    <typeAliases>
        <package name="com.whut.pojo"/>
    </typeAliases>
	<!--指定接口包中的接口（实现CRUD各种方法的接口）-->
    <mappers>
        <mapper class="com.whut.Mapper.BookMapper"/>
    </mappers>
</configuration>

整合Spring层，在resources下创建spring-dao.xml文件，该层主要是连接数据库（可以通过spring提供的接口，也可以是c3p0、dbcp等连接池）、通过连接数据库获取的数据源来获取SqlSessionFactory（产生sqlsession对象来实现CRUD）、扫描接口包，动态实现Dao接口可以注入到Spring容器中等。
可以将连接数据库信息的文件单独放在一个文件里，然后再spring-dao.xml中扫描识别。
比如：先在resources下创建database.properties文件

driver=com.mysql.jdbc.Driver
url=jdbc:mysql://localhost:3306/your database?useSSL=true&amp;useUnicode=true&amp;characterEncoding=utf-8
jdbc.username=root
password=root

<?xml version="1.0" encoding="UTF8"?>

<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:aop="http://www.springframework.org/schema/aop"
       xmlns:tx="http://www.springframework.org/schema/tx"
       xsi:schemaLocation="http://www.springframework.org/schema/beans
       http://www.springframework.org/schema/beans/spring-beans-3.0.xsd
       http://www.springframework.org/schema/context
       https://www.springframework.org/schema/context/spring-context.xsd
       http://www.springframework.org/schema/aop
       http://www.springframework.org/schema/aop/spring-aop.xsd
       http://www.springframework.org/schema/tx
       http://www.springframework.org/schema/tx/spring-tx.xsd">

    <!--关联数据库配置文件-->
    <context:property-placeholder location="classpath:database.properties"/>
    <!--通过spring api来获取datasource-->
    <bean id="dataSource" class="org.springframework.jdbc.datasource.DriverManagerDataSource">
        <property name="driverClassName" value="${driver}"/>
        <property name="url" value="${url}"/>
        <property name="username" value="${jdbc.username}"/>
        <property name="password" value="${password}"/>
    </bean>

    <!--SqlsessionFactory-->
    <bean id="sqlsessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
        <property name="dataSource" ref="dataSource"/>
        <!--绑定mybatis的配置文件-->
        <property name="configLocation" value="classpath:mybatis-config.xml"/>
    </bean>

    <!--配置Mapper接口扫描包，动态实现了Dao接口可以注入到Spring容器中-->
    <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
        <!--注入SqlsessionFactory-->
        <property name="sqlSessionFactoryBeanName" value="sqlsessionFactory"/>
        <!--要扫秒的包-->
        <property name="basePackage" value="com.whut.Mapper"/>
    </bean>
</beans>

整合spring mvc层,在resources文件夹下创建spring-mvc.xml。该层主要是注解驱动、扫描Controller包、定义视图解析器的前后缀等。

<?xml version="1.0" encoding="UTF8"?>

<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:aop="http://www.springframework.org/schema/aop"
       xmlns:tx="http://www.springframework.org/schema/tx"
       xmlns:mvc="http://www.springframework.org/schema/mvc"
       xsi:schemaLocation="http://www.springframework.org/schema/beans
       http://www.springframework.org/schema/beans/spring-beans-3.0.xsd
       http://www.springframework.org/schema/context
       https://www.springframework.org/schema/context/spring-context.xsd
       http://www.springframework.org/schema/aop
       http://www.springframework.org/schema/aop/spring-aop.xsd
       http://www.springframework.org/schema/tx
       http://www.springframework.org/schema/tx/spring-tx.xsd
       http://www.springframework.org/schema/mvc
       http://www.springframework.org/schema/mvc/spring-mvc.xsd">
    <!--1.注解驱动-->
    <mvc:annotation-driven/>
    <!--2.静态资源过滤-->
    <mvc:default-servlet-handler/>
    <!--3.扫描包-->
    <context:component-scan base-package="com.whut.Controller"/>
    <!--视图解析器-->
    <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
        <property name="prefix" value="/WEB-INF/JSP/"/>
        <property name="suffix" value=".jsp"/>
    </bean>
</beans>

此外还可以再编写一个service层的配置文件，来将实现类注入到spring中、在这里声明事务等。

<?xml version="1.0" encoding="UTF8"?>
<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:aop="http://www.springframework.org/schema/aop"
       xmlns:tx="http://www.springframework.org/schema/tx"
       xsi:schemaLocation="http://www.springframework.org/schema/beans
       http://www.springframework.org/schema/beans/spring-beans-3.0.xsd
       http://www.springframework.org/schema/context
       https://www.springframework.org/schema/context/spring-context.xsd
       http://www.springframework.org/schema/aop
       http://www.springframework.org/schema/aop/spring-aop.xsd
       http://www.springframework.org/schema/tx
       http://www.springframework.org/schema/tx/spring-tx.xsd">
    <!--1.扫描service下的包-->
    <context:component-scan base-package="com.whut.Service"/>
    <!--2.将我们的业务类，注入到spring，可以通过配置，或者注解实现-->
    <bean id="BookServiceImpl" class="com.whut.Service.BookServiceImpl">
        <property name="bookMapper" ref="bookMapper"/>
    </bean>
    <!--3.声明式事务配置-->
    <bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
        <!--注入数据源-->
        <property name="dataSource" ref="dataSource"/>
    </bean>
</beans>

整体整合，就是将刚才各个层的配置文件整合在一起，在resources文件夹下创建application.xml，将其他配置文件引入到这里。

<?xml version="1.0" encoding="UTF8"?>

<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:aop="http://www.springframework.org/schema/aop"
       xmlns:tx="http://www.springframework.org/schema/tx"
       xsi:schemaLocation="http://www.springframework.org/schema/beans
       http://www.springframework.org/schema/beans/spring-beans-3.0.xsd
       http://www.springframework.org/schema/context
       https://www.springframework.org/schema/context/spring-context.xsd
       http://www.springframework.org/schema/aop
       http://www.springframework.org/schema/aop/spring-aop.xsd
       http://www.springframework.org/schema/tx
       http://www.springframework.org/schema/tx/spring-tx.xsd">
    <import resource="classpath:spring-dao.xml"/>
    <import resource="classpath:spring-service.xml"/>
    <import resource="classpath:spring-mvc.xml"/>
</beans>
