mybatis这边连接mysql进行模糊查询，并未更改xml文件中的sql语句。也就是说，同样的sql，在spring boot集成了druid之前是完全支持可以查询的，集成之后查询出错，报错如最上面。

感觉是druid的问题，

mapper.xml修改最后如下：

<?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="com.sxd.swapping.dao.mybatis.HuaYangAreaMapper">

    <select
            id="findByNameAndPersonAndCreateDate"
            parameterType="com.sxd.swapping.domain.HuaYangArea"
            resultType="com.sxd.swapping.base.HuaYangModelBean">


        select
            hy.uid uid,
            hy.create_date createDate,
            hy.update_date updateDate,
            hy.area_name areaName,
            hy.area_person areaPerson
        from
            hua_yang_area AS hy

        <where>
            1=1
            <if test="areaName != null">
                AND hy.area_name LIKE '%${areaName}%'
            </if>

            <if test="areaPerson != null">
                AND hy.area_person >= #{areaPerson}
            </if>

            <if test="createDate != null">
                AND <![CDATA[hy.create_date >= #{createDate}]]>
            </if>

        </where>

    </select>

也就是吧原本的

<if test="areaName != null">
                AND hy.area_name LIKE '%' #{areaName} '%'
            </if>

修改为

<if test="areaName != null">
                AND hy.area_name LIKE '%${areaName}%'
            </if>
