做分頁查詢時，查詢符合條件的總記錄數報錯：

    java.lang.RuntimeException: org.mybatis.spring.MyBatisSystemException: nested exception is org.apache.ibatis.reflection.ReflectionException: There is no getter for property named 'nameText' in 'class java.lang.String'

mapper.xml的寫法為：

    <select id="getUserCount" resultMap="ResultMapWithBLOBs">
    select count(*) 
    from user 
    <if test="nameText != null">
        where name like CONCAT(CONCAT('%', #{nameText}), '%')
    </if>
  </select>

原因：介面中返回值為int，所以這裡的resultMap不可以是實體類，而應該是Integer，修改為：

<select id="getUserCount" parameterType="string" resultType="int">
    select count(*) 
    from user 
    <if test="nameText != null">
        where name like CONCAT(CONCAT('%', #{nameText}), '%')
    </if>
  </select>

int getUserCount(@Param("nameText") String nameText);
