一、需要引入Mybatis 和Spring 整合需要的jar

        mybatis需要的jar：

  <!--引入工程需要的jar-->
        <!-- 实体注解-->
        <dependency>
            <groupId>org.projectlombok</groupId>
            <artifactId>lombok</artifactId>
            <version>1.18.24</version>
        </dependency>
        <!--mybatis-->
        <dependency>
            <groupId>org.mybatis</groupId>
            <artifactId>mybatis</artifactId>
            <version>3.5.9</version>
        </dependency>
        <!--mybatis分页插件的jar-->
        <dependency>
            <groupId>com.github.pagehelper</groupId>

            <artifactId>log4j</artifactId>
            <version>1.2.17</version>
        </dependency>
        <!--junit-->
        <dependency>
            <groupId>junit</groupId>
            <artifactId>junit</artifactId>
            <version>4.13</version>
        </dependency>
        <!--servlet-->
        <dependency>
            <groupId>javax.servlet</groupId>
            <artifactId>javax.servlet-api</artifactId>

        </dependency>
        <!--jsp-->
        <dependency>
            <groupId>javax.servlet.jsp</groupId>
            <artifactId>javax.servlet.jsp-api</artifactId>
            <version>2.3.1</version>
        </dependency>
        <!--jstl-->
        <dependency>
            <groupId>jstl</groupId>
            <artifactId>jstl</artifactId>
            <version>1.2</version>
        </dependency>
        <!--fastjson-->
        <dependency>
            <groupId>com.alibaba</groupId>
            <artifactId>fastjson</artifactId>
            <version>1.2.50</version>
        </dependency>

        spring本身需要以及和mybatis整合需要的jar

<dependency>
            <groupId>org.mybatis</groupId>
            <artifactId>mybatis-spring</artifactId>
            <version>2.0.3</version>
        </dependency>
        <dependency>
            <groupId>com.alibaba</groupId>
            <artifactId>druid</artifactId>
            <version>1.2.8</version>
        </dependency>
        <dependency>
            <groupId>org.springframework</groupId>
            <artifactId>spring-context</artifactId>
            <version>5.2.4.RELEASE</version>
        </dependency>

        <!--https://mvnrepository.com/artifact/org.springframework/spring-core -->
        <dependency>
            <groupId>org.springframework</groupId>
            <artifactId>spring-core</artifactId>
            <version>5.2.9.RELEASE</version>
        </dependency>

        <!--https://mvnrepository.com/artifact/org.springframework/spring-beans -->
        <dependency>
            <groupId>org.springframework</groupId>
            <artifactId>spring-beans</artifactId>
            <version>5.2.9.RELEASE</version>
        </dependency>

        <dependency>
            <groupId>org.springframework</groupId>
            <artifactId>spring-aspects</artifactId>
            <version>5.2.4.RELEASE</version>
        </dependency>

        <dependency>
            <groupId>org.springframework</groupId>
            <artifactId>spring-jdbc</artifactId>
            <version>5.2.4.RELEASE</version>
        </dependency>

        <dependency>
            <groupId>org.springframework</groupId>
            <artifactId>spring-webmvc</artifactId>
            <version>5.2.4.RELEASE</version>
        </dependency>
        <!-- https://mvnrepository.com/artifact/commons-logging/commons-logging -->
        <dependency>
            <groupId>commons-logging</groupId>
            <artifactId>commons-logging</artifactId>
            <version>1.2</version>
        </dependency>

二、创建spring配置文件中的内容

        Mybatis的使用：

                1、加载Mybatis的配置文件

                2、三个核心对象

                        -SqlSessionFactoryBuilder

                        -SqlSessionFactory

                        -SqlSession（CRUD）

                                -直接调用SqlSession中的CRUD

                                -直接使用Mapper调用

                3、使用注解开发

         1）在头文件配置创建context相关命名空间

                 开启创建实体类对象的注解扫描

         2）引入德鲁伊连接池的dateSource数据源对象

        3）创建sqlSessionFactory线程工厂对象装配数据源对象，同时引入mybatis.xml配置文件

          4）在指定com.xja.mapper包扫描mapper接口，并生成接口类型class为对应mybatis的mapper类型对象。

         5）mybatis 添加需要的对应持久层的设置
