這個問題把小編急毀了，搗騰了好幾天還沒有結果出來，今天終于搗騰出來了，下面小編把經過分享給大家，大家多多提出寶貴意見。

錯誤信息關鍵描述
Parameter index out of range (1 > number of parameters, which is 0)
反正就是說我的參數存在問題
業務代碼描述
修改班級信息時可以修改班級對應班主任，所以需要查詢出對應的非班主任教師。
Handler
@RequestMapping(value="edit/class/{classId}", method=RequestMethod.GET)
public ModelAndView preUpdateClass(@PathVariable("classId") Integer classId) {
logger.info("預修改班級處理");
ModelAndView model = new ModelAndView();
//獲取要修改班級
ClassInfo classInfo = classInfoService.getClassById(classId);
model.setViewName("/admin/classedit");
model.addObject("editClass", classInfo);
List<GradeInfo> grades = gradeInfoService.getGrades();
//獲取不是班主任的教師
teacher.setIsWork(0); // isWork為0就不是班主任
List<TeacherInfo> teachers = teacherInfoService.getTeachers(null); //通過下面配置文件可知，該方法需要傳入一個 Map 集合，而我這里傳入一個 null
//如果沒有可用班主任
if (teachers.size() == 0 || teachers == null) {
teacher.setTeacherId(classInfo.getTeacher().getTeacherId());
teacher.setTeacherName("暫無剩余教師");
teachers.add(teacher);
}
model.addObject("teachers", teachers);
model.addObject("grades", grades);
return model;
}
映射文件
Statement會接收一個 Map 集合
<resultMap type="com.taohan.online.exam.po.TeacherInfo" id="getTeacherResultMap">
<id column="teacherId" property="teacherId"/>
<result column="teacherName" property="teacherName" />
<result column="teacherAccount" property="teacherAccount"/>
<result column="teacherPwd" property="teacherPwd"/>
<result column="adminPower" property="adminPower"/>
<result column="isWork" property="isWork"/>
<association property="classInfo" javaType="com.taohan.online.exam.po.ClassInfo">
<id column="classId" property="classId"/>
<result column="className" property="className"/>
</association>
</resultMap>
<parameterMap type="java.util.Map" id="getTeachersParameterMap">
<!-- 教師對象 -->
<parameter property="teacher" resultMap="getTeacherResultMap"/>
<!-- 起始位置索引 -->
<parameter property="startIndex" resultMap="getTeacherResultMap"/>
<!-- 每頁顯示數據量 -->
<parameter property="pageShow" resultMap="getTeacherResultMap"/>
</parameterMap>
<!-- 使用 paramenterMap 查詢 -->
<select id="getTeachers" parameterMap="getTeachersParameterMap" resultMap="getTeacherResultMap">
SELECT a.*,b.classId,b.className FROM TeacherInfo a
INNER JOIN ClassInfo b ON a.teacherId=b.teacherId
<!--
getTeachers()方法我傳入的是 null，那么，在下面進行條件判斷的時候并不能找到 teacher、startIndex、pageShow，所以拋出異常
-->
<where>
<if test="teacher != null">
isWork=#{teacher.isWork}
</if>
</where>
<if test="startIndex != null and pageShow != null">
LIMIT #{startIndex}, #{pageShow}
</if>
</select>
總結
通過之前犯過類似的錯誤，以及這次錯誤，我發現 今后只要是 Parameter index out of range (1 > number of parameters, which is 0) 類似的錯誤大致定位在 映射文件和調用方法傳入參數，
映射文件
如果使用了 parameterMap, resultMap，或是返回集合，就要檢查參數名稱和屬性名稱是否一致
調用方法
針對使用了 parameterMap 或 parameterType，需要檢查傳入Map中的鍵是否存在、匹配，或傳入對象是否存在指定屬性
下面看下在數據庫中遇到Parameter index out of range 錯誤該如何處理？
最近學ssm框架的時候，遇到了這個錯誤，找了半天的原因，最后發現原來是sql語句中多了一對單引號。傳入值的類型為String類型，就以為還要加引號以表示傳入的是字符串，其實是錯的，還是初學對其還不太了解。
如下：
錯誤的：
<update id="updateState" parameterType="java.lang.String">
UPDATE login SET State = 0 WHERE LID = '#{value}'
</update>
正確的：
<update id="updateState" parameterType="java.lang.String">
UPDATE login SET State = 0 WHERE LID = #{value}
</update>
以上所述是小編給大家介紹的Mabatis錯誤提示Parameter index out of range的處理方法，希望對大家有所幫助，如果大家有任何疑問請給我留言，小編會及時回復大家的。在此也非常感謝大家對億速云網站的支持！
