@MapperScanner 没有

在提到SpringBoot中的@MapperScanner时，可以看到它的注解上加了@Import注解，且引入的MapperScannerRegistrar类是ImportBeanDefinitionRegistrar的子类。如果在SpringBoot的启动主类中没有定义@MapperScan注解，那么SpringBoot的BeanDefinitionRegistry组件将不会加载MapperFactoryBean和MapperScannerConfigurer类，而是会加载MapperScannerRegistrarNotFoundConfiguration内部类。这就意味着，如果没有显式使用@MapperScan注解，SpringBoot会使用自动配置类AutoConfiguredMapperScannerRegistrar来进行Mapper的扫描注册。所以，如果没有使用@MapperScan注解，@MapperScanner仍然能够生效，只是会使用自动配置的方式来注册Mapper接口。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
