使用Spring Config创建泛型类型

@Configuration
public class GenericConfig<T> {

    @Bean
    public T genericBean() {
        // 返回泛型类型的Bean
        return null;
    }
}

@Configuration
public class MyConfig extends GenericConfig<MyBean> {

    @Override
    public MyBean genericBean() {
        // 返回具体的Bean
        return new MyBean();
    }
}

@SpringBootApplication
public class MyApplication {

    public static void main(String[] args) {
        SpringApplication.run(MyApplication.class, args);
    }

    @Autowired
    private MyBean myBean;

    // ...
}
