springboot整合mybatis的時候報錯Caused by: java.lang.IllegalArgumentException: Property 'sqlSessionFa...

今天閒來無事，學習springboot整合mybatis，在bilibili看視頻學的，視頻中在dao層的interface上面加上org.apache.ibatis.annotations.Mapper註解就能夠了，可是我一直報錯。這個應該是springboot整合mybatis的一個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)

 

第一個報錯的解決方式就是org.mybatis.spring.annotation.MapperScan註解

 

 

 

能夠看到報錯已經變了，說明dao層的接口已經委託給spring管理了，可是報錯變成了：

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

 

這個報錯的緣由是我以前引入oracle的座標的時候，有報錯，由於oracle不是免費的，因此在@SpringBootApplication註解後面加了一個排除數據源配置的屬性，@SpringBootApplication(exclude = DataSourceAutoConfiguration.class)，到這裏你們應該都知道問題的所在了吧。

那就是Mybatis本生就是用來管理數據源的一個東西，exclude = DataSourceAutoConfiguration.class加上後，mybatis的自動裝配就無法完成，因此就報錯：

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