今天在整合通过springboot2.0整合mybatis时出现了一个错误：

Caused by: org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'userInfoMapper' defined in file [F:\code\idea_work_code\test\xsignal2-saas\xsignal2-user-model\target\classes\com\yingda\xsignal\user\dao\UserInfoMapper.class]: Invocation of init method failed; nested exception is java.lang.IllegalArgumentException: Property 'sqlSessionFactory' or 'sqlSessionTemplate' are required

找了很久发现mybatis的相关jar org.mybatis 和 mybatis-spring都已经引入了，而且启动类也加上了注解@MapperScan({"com.yingda.xsignal.user.dao"})，

后来才发现少了一个springboot 和mybatis集成的jar mybatis-spring-boot-starter，此时心里有千万头xxx在奔腾.......

<dependency>
            <groupId>org.mybatis.spring.boot</groupId>
            <artifactId>mybatis-spring-boot-starter</artifactId>
            <version>1.3.2</version>
        </dependency>

        <!--mybatis-->
        <!-- https://mvnrepository.com/artifact/org.mybatis/mybatis -->
        <dependency>
            <groupId>org.mybatis</groupId>
            <artifactId>mybatis</artifactId>
            <version>3.4.5</version>
        </dependency>

        <!-- https://mvnrepository.com/artifact/org.mybatis/mybatis-spring -->
        <dependency>
            <groupId>org.mybatis</groupId>
            <artifactId>mybatis-spring</artifactId>
            <version>1.3.2</version>
        </dependency>

加入了以上jar，重新启动项目ok
