出錯部分的程式碼如下:

  <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>

引數部分修改為如下即可:

<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>
