今天闲来无事，学习springboot整合mybatis，在bilibili看视频学的，视频中在dao层的interface上面加上org.apache.ibatis.annotations.Mapper注解就可以了，但是我一直报错。这个应该是springboot整合mybatis的一个bug（新版的）

Description:

Field userDao in com.yuanqiao.service.impl.UserServiceImpl required a bean of type 'com.yuanqiao.dao.UserDao' that could not be found.

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

第一个报错的解决方式就是org.mybatis.spring.annotation.MapperScan注解

可以看到报错已经变了，说明dao层的接口已经委托给spring管理了，但是报错变成了：

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'userDao' defined in file \[H:\\WorkSpace\\idea20170307\\swaggerdemo\\target\\classes\\com\\yuanqiao\\dao\\UserDao.class\]: Invocation of init method failed; nested exception is java.lang.IllegalArgumentException: Property 'sqlSessionFactory' or 'sqlSessionTemplate' are required

Caused by: java.lang.IllegalArgumentException: Property 'sqlSessionFactory' or 'sqlSessionTemplate' are required

这个报错的原因是我之前引入oracle的坐标的时候，有报错，因为oracle不是免费的，所以在@SpringBootApplication注解后面加了一个排除数据源配置的属性，@SpringBootApplication(exclude = DataSourceAutoConfiguration.class)，到这里大家应该都知道问题的所在了吧。

那就是Mybatis本生就是用来管理数据源的一个东西，exclude = DataSourceAutoConfiguration.class加上后，mybatis的自动装配就没法完成，所以就报错：

Caused by: java.lang.IllegalArgumentException: Property 'sqlSessionFactory' or 'sqlSessionTemplate' are required

pom.xml内容如下：
