springboot启动报错：java.lang.IllegalArgumentException: Property 'sqlSessionFactory' or 'sqlSessionTempla

参考了这篇博文：https://www.cnblogs.com/dbaxyx/p/10663485.html

报错信息：

Caused by: java.lang.IllegalArgumentException: Property 'sqlSessionFactory' or 'sqlSessionTemplate' are required
    at org.springframework.util.Assert.notNull(Assert.java:198)
    at org.mybatis.spring.support.SqlSessionDaoSupport.checkDaoConfig(SqlSessionDaoSupport.java:74)

 这是因为没有引入一个包：

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

引入就可以了（要注意jar包冲突）
