mybatis 中 if else 用法 mybatis中文网
在 mybaits 中,只有 if 标签,并没有 else 标签,可以使用 chose when otherwise 代替。
<choose>
<when test="">
//...
</when>
<otherwise>
//...
</otherwise>
</choose>
<select id="findActiveBlogLike"
resultType="Blog">

</when>
<when test="author != null and author.name != null">

</when>
<otherwise>
AND featured = 1
</otherwise>
</choose>
</select>
