今天要做一个模糊查询

用的Mybatis

开始写的是:

[html] view plaincopy
select id,bookName,author,publisher,donor,status,createDate,lastUpdate from book
<where>
<if test="bookName!=null">
bookName like '%#{bookName}%'
</if>
<if test="author!=null">
and author like '%#{author}%'
</if>


最后改为:

[html] view plaincopy
select id,bookName,author,publisher,donor,status,createDate,lastUpdate from book
<where>
<if test="bookName!=null">
bookName like CONCAT('%','${bookName}','%' )
</if>
<if test="author!=null">
and author like CONCAT('%','${author}','%' )
</if>
主要还是MyBatis传值的问题啊

如果不是字符串就没法替换了
