官方说明：MyBatis Spring-Boot-Starter will help you use MyBatis with Spring Boot  
其实就是myBatis看spring boot这么火热也开发出一套解决方案来凑凑热闹,但这一凑确实解决了很多问题，使用起来确实顺畅了许多。mybatis-spring-boot-starter主要有两种解决方案，一种是使用注解解决一切问题，一种是简化后的老传统。  
当然任何模式都需要首先引入mybatis-spring-boot-starter的pom文件

<dependency>
        <groupId>org.mybatis.spring.boot</groupId>
        <artifactId>mybatis-spring-boot-starter</artifactId>
        <version>1.1.1</version>
    </dependency>

有两种配置方式  
1.注解 简单快速  
2.xml 更灵活,与传统适用方式相似

———————————————我使用xml的形式————————–  
1.准备好相关所需要的依赖

<dependencies>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter</artifactId>
        </dependency>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-test</artifactId>
            <scope>test</scope>
        </dependency>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-web</artifactId>
        </dependency>
        <dependency>
            <groupId>org.mybatis.spring.boot</groupId>
            <artifactId>mybatis-spring-boot-starter</artifactId>
            <version>1.1.1</version>
        </dependency>
         <dependency>
            <groupId>mysql</groupId>
            <artifactId>mysql-connector-java</artifactId>
        </dependency>
         <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-devtools</artifactId>
            <optional>true</optional>
        </dependency>
    </dependencies>

2.application,properties添加配置  
mybatis.type-aliases-package=com.dongshuo.springboottest.entity  
mybatis.config-locations=classpath:mybatis/mybatis-config.xml  
mybatis.mapper-locations=classpath:mybatis/\*Mapper.xml  
spring.datasource.url=jdbc:mysql://127.0.0.1:3306/dongshuo  
spring.datasource.username=root  
spring.datasource.password=root  
spring.datasource.driver-class-name=com.mysql.jdbc.Driver

注意:!!xml文件头验证 可选择忽略ignore

3.程序入口application.java  
需要使用@MapperScan(“package”) 进行扫描接口
