Error creating bean with name ‘adminMapper‘ Injection of resource dependencies failed

Project scenario:

SpringBoot project, unable to create bean object, unable to inject dependencies

---

Problem Description:

org.springframework.beans.factory.BeanCreationException: Error creating bean with name
'adminService': 
 Injection of resource dependencies failed; nested exception is org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 
'adminMapper' defined in file [E:\IdeaCode\toyrentalplatform\target\classes\cn\gestwr\toy\dao\AdminMapper.class]: Unsatisfied dependency expressed through bean property 
'sqlSessionFactory'; nested exception is org.springframework.beans.factory.BeanCreationException:

Cause Analysis:

After many times of querying Baidu, Stack Overflow, and self-inspection, it was finally found that it was a problem with the configuration file application.properties

---

solution:

The configuration file configuration option is wrong, for example: the following configuration is added and an error is reported

mybatis.configuration.log-impl=org.apache.ibatis.logging.stdout.StdOutImpl

In the properties file, the color of this configuration is different from that of other configurations, the correct one is light green

I don't know the reason for the time being, if you know the big guy, you can comment and let me know -0-

Pay attention to the format of the yml configuration file
