question
java spring-boot
springboot/mybatis : test run→Failed to instantiate [org.mybatis.spring.SqlSessionFactoryBean]
(追記)  
現時点において、 Spring Boot 3 で mybatis-spring-boot-starter を利用したい場合には
[2.3.0-SNAPSHOT](https://github.com/mybatis/spring-boot-starter/issues/697)
を利用すれば良さそうです。  
(追記終わり)

mybatis-spring-boot-starter はまだ Spring Boot 3 には対応していないと考えられます。  
Spring Boot のバージョンを安定板(2.7.5 など)にして試してみてください。

* * *

例外スタックトレースに

```

    Caused by: java.lang.ClassNotFoundException: org.springframework.core.NestedIOException
    
```

と表れていますが、この `NestedIOException` は Spring Boot 3(が依存している Spring Framework 6)
で[削除されています](https://github.com/spring-projects/spring-framework/issues/28198)。

他方、 MyBatis 側では mybatis-spirng のバージョン 2.1.0
でこれに対する[対応が行われています](https://github.com/mybatis/spring/pull/663)。  
しかし mybatis-spring-boot-starter の最新版 2.2.2 ではまだ上記の対応が為されていない [mybatis-spirng
バージョン 2.0.7](https://github.com/mybatis/spring-boot-starter/blob/mybatis-
spring-boot-2.2.2/pom.xml#L71) が採用されています。
