import org.apache.ibatis.annotations.CacheNamespace;
import org.apache.ibatis.annotations.Select;
import org.apache.ibatis.annotations.Mapper;
import org.apache.ibatis.cache.impl.PerpetualCache;

@Mapper
@CacheNamespace(implementation = PerpetualCache.class, blocking = false)
public interface MyMapper {

    @Select("SELECT * FROM my_table WHERE id = #{id}")
    MyEntity selectById(int id);

}

上使用@CacheNamespace注解，并将implementation设置为org.apache.ibatis.cache.impl.PerpetualCache.class，blocking设置为false即可禁用二级缓存
