springboot操作mybatis注入问题的锅

The injection point has the following annotations:
    - @org.springframework.beans.factory.annotation.Autowired(required=true)

Action:

Consider defining a bean of type 'com.hjc.bootdemo.dao.UserDao' in your configuration.

这个问题是由于jar包依赖问题引起的，springboot的jar包的依赖不对，正确的依赖是

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