How to use dynamic SQL query in MyBatis with annotation(how to use selectProvider)?

I am trying to avoid having an additional xml to define the mapper in mybatis3. Annotation fits right in.

I am a bit confused by the usage of @SelectProvider/@InsertProvider/etc. Don't think there are many resources online guiding me through this.

Basically, I will like to find the annotation version of alternative for in mybatis3.

For example, I have a xml mapper and I wanna convert it to use annotation

<select ...>
  <where>
    <if cause.....>
    </if>
    <if cause......>
    </if>
  </where>
</select>

Could anyone provide a concrete answer/solution including the code?

Thanks in advance!
