今天的内容:
学习Mybatis的choose、when、otherwise标签(可以在多条件中选择一个相当于ifelse):
官方示例:
<select id="findActiveBlogLike" resultType="Blog"> SELECT * FROM BLOG WHERE state = ‘ACTIVE’ <choose> <when test="title != null"> AND title like #{title} </when> <when test="author != null and author.name != null"> AND author_name like #{author.name} </when> <otherwise> AND featured = 1 </otherwise> </choose> </select>
问题:无
明天的打算:继续学习Mybatis
