在SpringBoot项目中整合Mybatis时遇到错误：'deptController'的bean创建失败，原因是'departmentMapper'字段的依赖未满足。错误深入到'DepartmentMapper'的bean定义，指出'sqlSessionFactory'的bean创建失败，因为'mybatis/mybatis-config.xml'资源无法打开。解决方案包括检查XML映射文件的命名空间和结果类型全限定名是否正确，以及YML配置文件中Mybatis的config和mapper路径设置。

Error creating bean with name 'deptController': Unsatisfied dependency expressed through field 'departmentMapper'; nested exception is org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'departmentMapper' defined in file [D:\demo16\target\classes\com\example\demo\mapper\DepartmentMapper.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 [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.FileNotFoundException: class path resource [mybatis/mybaties-config.xml] cannot be opened because it does not exist

出错情况分析：

1.映射xml文件中的namespace和resultType全类名注意引用正确；

2.yml文件中mybatis的config和mapper地址注意，最好直接引用，不手打。
