文章描述了在SpringBoot项目中使用MyBatisPlus时遇到的依赖注入问题，发现是由于不同版本的Mybatis-PlusStarter之间的差异引发的。通过将版本从3.5.5降级到3.5.1解决了问题。

org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'userServiceImpl': Unsatisfied dependency expressed through field 'baseMapper'; nested exception is org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'userMapper' defined in file [E:\javaCode\userCentor\target\classes\com\example\usercentor\mapper\UserMapper.class]: Unsatisfied dependency expressed through bean property 'sqlSessionFactory'; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'sqlSessionFactory' defined in class path resource [com/baomidou/mybatisplus/autoconfigure/MybatisPlusAutoConfiguration.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.lang.BootstrapMethodError: java.lang.NoSuchMethodError: org.apache.ibatis.session.Configuration.setArgNameBasedConstructorAutoMapping(Z)V

一直提示bean对象无法注入，看了好个帖子都是说@Mapper注解的问题，检查代码从serviceImp到@Mapper以及通过My Batis X生产的mapper.xml都没有问题。

最后重新看了pom.xml，发现

<dependency>
            <groupId>com.baomidou</groupId>
            <artifactId>mybatis-plus-spring-boot3-starter</artifactId>
            <version>3.5.5</version>
        </dependency>

改为

<dependency>
    <groupId>com.baomidou</groupId>
    <artifactId>mybatis-plus-boot-starter</artifactId>
    <version>3.5.1</version>
</dependency>

后解决问题
