出错部分的代码如下：

  <select id="getCurrentMaxNodeValue" parameterType="java.lang.String" resultType="java.lang.String">        SELECT id FROM tableA        <where>            <choose>                <when test="id != null">                    parent_id=${id}                </when>                <otherwise>                    IFNULL(parent_id,'')=''                </otherwise>            </choose>        </where>        ORDER BY id DESC LIMIT 1    </select>

参数部分修改为如下即可：

<select id="getCurrentMaxNodeValue" parameterType="java.lang.String" resultType="java.lang.String">        SELECT id FROM tableA        <where>            <choose>                <when test="_parameter != null">                    parent_id=${_parameter}                </when>                <otherwise>                    IFNULL(parent_id,'')=''                </otherwise>            </choose>        </where>        ORDER BY id DESC LIMIT 1    </select>
