mybatis使用动态sql时报错：There is no getter for property named '*' in 'class java.lang.String

mybatis使用动态sql：如<if><when><trim><where>，而parameterType又恰好是string，

如下：

<select id="getP_VListWithParams" parameterType="string" resultMap="p_vMap">
       select * from p_v 
        <where>
            <if test="<span style="background-color: rgb(51, 204, 0);"><strong><span style="font-size:24px;">p_v_id</span></strong></span>!= null">
                locate (#{p_v_id},p_v_id)
            </if>
            </where>
 </select>

此时，如果程序调用到getP_VListWithParams方法，则会报错：There is no getter for property named '*' in 'class java.lang.String

临时性的解决方案，把<if>检测语句中的p_v_id替换成_parameter，即：

<span style="background-color: rgb(240, 240, 240);"><select id="getP_VListWithParams" parameterType="string" resultMap="p_vMap">
       select * from p_v 
        <where>
            <if test="</span><span style="font-size:24px;"><strong><span style="background-color: rgb(0, 153, 0);">_parameter</span><span style="color:#33cc00;background-color: rgb(240, 240, 240);"> </span></strong></span><span style="background-color: rgb(240, 240, 240);">!= null">
                locate (#{p_v_id},p_v_id)
            </if>
            </where>
    </select></span>
