SpringBoot整合MyBatis报错IllegalArgumentException

描述

  • 场景：

先在Mapper接口里添加了一个查询方法，然后在service层中使用该查询方法，最后由控制器方法返回该查询结果。

结果运行的时候报错：

异常原因

大概率是因为mybatis启动器依赖不兼容，然后去Spring官网的spring initializr里创建相同SpringBoot版本的项目，发现里面引入的mybtais启动器版本为3.0.3，而我手动引入的版本为3.0.0。

		</plugins>
	</build>

</project>

在将pom.xml里的myabtis启动器版本改为3.0.3后就成功运行了。
在这里插入图片描述
所以，以后添加依赖还是直接使用spring initializr创建项目，并选中对应的依赖启动器。

道可道，非常道；名可名，非常名。 无名，天地之始，有名，万物之母。 故常无欲，以观其妙，常有欲，以观其徼。 此两者，同出而异名，同谓之玄，玄之又玄，众妙之门。
