2023-06-16T23:25:44.570+08:00 ERROR 15752 --- [           main] o.s.b.d.LoggingFailureAnalysisReporter   : 

Field userMapper in com.example.service.impl.UserServiceImpl required a bean of type 'com.example.mapper.UserMapper' that could not be found.

The injection point has the following annotations:
	- @org.springframework.beans.factory.annotation.Autowired(required=true)


Action:

Consider defining a bean of type 'com.example.mapper.UserMapper' in your configuration.

• 没有排除自动配置的情况下，由于Mapper接口代理对象无法创建，导致Service中需要注入该Mapper接口代理Bean对象的属性无法自动注入，最终导致Springboot程序无法启动
  • 排除自动配置：@SpringBootApplication(exclude= {DataSourceAutoConfiguration.class})
• 会导致上述错误，是由于：底层SqlSessionFactory对象无法创建，导致Mapper接口代理对象无法创建

解决方法

• 如果排除了自动配置：@SpringBootApplication(exclude= {DataSourceAutoConfiguration.class})，不要排除自动配置
• 没有排除自动配置，可以把MyBatisPlus starter版本更换为最新版
  • 此时，使用的SpringBoot版本为3.1.0，MyBatisPlus starter最新版本为3.5.3.1
