求，SpringMVC+MyBatis免xml的纯java注解配置方式？

Question

不想做伸手党，这次实在没办法；
新项目需要用到mybatis，之前公司一直用springMvc+hibernate，
都是用一个WebApplicationInitializer实现类+WebMvcConfiguration实现类
用纯注解方式配置。
然而自己只会用xml配置mybatis，找得到注解写mybatis的sql语句，
但实在找不到SpringMVC+MyBatis的配置注解，百度的净是些挂羊头卖狗肉的
xml配置，
只能求助于各位道友了？

        configuration.addInterceptor(pageInterceptor);

        return configuration;
