중요에러부분

Error creating bean with name 'sqlSessionFactory' defined in class path resource [org/mybatis/spring/boot/autoconfigure/MybatisAutoConfiguration.class]:
        Bean instantiation via factory method failed; nested exception is org.springframework.beans.BeanInstantiationException: Failed to instantiate [org.apache.ibatis.session.SqlSessionFactory]: 
        Factory method 'sqlSessionFactory' threw exception; nested exception is java.io.IOException: Failed to parse mapping resource: ''

 

'sqlSessionFactory' defined in class path resource

 [org/mybatis/spring/boot/autoconfigure/MybatisAutoConfiguration.class]:

 

 

Mybatis와 Mybatis-spring 버전이 맞지 않아서 생긴 오류인 것을 알 수 있다.

https://mvnrepository.com/ 에서 Mybatis-spring와 맞는 Mybatis의존성을 추가했다. (pox.xml에 추가)

 

 

 

수정전

<dependency>
   <groupId>org.mybatis.spring.boot</groupId>
   <artifactId>mybatis-spring-boot-starter</artifactId>
   <version>2.3.0</version>
</dependency>

수정후

<dependency>
   <groupId>org.mybatis.spring.boot</groupId>
   <artifactId>mybatis-spring-boot-starter</artifactId>
   <version>2.3.0</version>
</dependency>
<dependency>
   <groupId>org.mybatis</groupId>
   <artifactId>mybatis</artifactId>
   <version>2.3.5</version>
</dependency>

 

추가 로 해결

 

맞는 버전인 3.5.11 인거같은데 에러난다.. 그래서 2.3.5를 추개해줬다.
