Spring Couldn’t autowired,there is more than one bean of “ type

Spring is confused between the 2 beans you have declared in you configuration class so you can use @Qualifier annotation along with @Autowired to remove the confusion by specifying which exact bean will be wired, apply these modifications on your configuration class

@Configuration
public class SpringConfig {
    @Bean(name="clazzImplA")
    public BaseInterface clazzImplA(){
        return new ClazzImplA();
    }

    @Bean(name="clazzImplB")
    public BaseInterface clazzImplB(){
        return new ClazzImplB();
    }
}

then at @autowired annotation

@Service
@SpringApplicationConfiguration(SpringConfig.class)
public class AutowiredClazz {
    @Autowired
    @Qualifier("the name of the desired bean")
    private BaseInterface baseInterface;

    private AutowiredClazz(BaseInterface baseInterface){
        this.baseInterface = baseInterface;
    }
}
