Mybatis中的like查询

今天要做一个模糊查询

用的Mybatis

开始写的是：

 

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：

 

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
