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
