mybatis实现模糊查询

记录一下mybatis实现模糊查询的实现

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE mapper
        PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN"
        "http://mybatis.org/dtd/mybatis-3-mapper.dtd">
<mapper namespace="org.ruiskey.mapper.UserMapper">
    <select id="getPage" resultType="org.ruiskey.entity.User">
        select * from user where username like '%${username}%' limit #{pageNum}, #{pageSize}
    </select>
</mapper>

注意这里是%${username}%, 而不是%#{username}%
