MyBatis报错笔记——Could not find parameter map XXX.XXX.xml

出错问题是 XXX-XXX.xml中相应的关键字写错了：将parameterType写错成parameterMap。这才会出错。

解决办法就是将写错的parameterMap改为parameterType

<select id="selectDynamicEmployee" resultType="com.qst.bean.Employee" parameterMap="com.qst.bean.Employee">
        select * from tb_employee where 1=1
        <if test="name!=null and name!=''">
            and name =#{name}
        </if>
        <if test="gender!=null and gender!=''">
            and gender =#{gender}
        </if>
    </select>

改为

  <select id="selectDynamicEmployee" resultType="com.qst.bean.Employee" parameterType="com.qst.bean.Employee">
        select * from tb_employee where 1=1
        <if test="name!=null and name!=''">
            and name =#{name}
        </if>
        <if test="gender!=null and gender!=''">
            and gender =#{gender}
        </if>
    </select>

正常输出结果
