孙池暝
本文向大家介绍Mabatis错误提示Parameter index out of range的处理方法，包括了Mabatis错误提示Parameter index out of range的处理方法的使用技巧和注意事项，需要的朋友参考一下
这个问题把小编急毁了，捣腾了好几天还没有结果出来，今天终于捣腾出来了，下面小编把经过分享给大家，大家多多提出宝贵意见。
错误信息如下

错误信息关键描述
Parameter index out of range (1 > number of parameters, which is 0)
反正就是说我的参数存在问题
业务代码描述
修改班级信息时可以修改班级对应班主任，所以需要查询出对应的非班主任教师。
Handler
@RequestMapping(value="edit/class/{classId}", method=RequestMethod.GET)
public ModelAndView preUpdateClass(@PathVariable("classId") Integer classId) {
logger.info("预修改班级处理");
ModelAndView model = new ModelAndView();
//获取要修改班级
ClassInfo classInfo = classInfoService.getClassById(classId);
model.setViewName("/admin/classedit");
model.addObject("editClass", classInfo);
List<GradeInfo> grades = gradeInfoService.getGrades();
//获取不是班主任的教师
teacher.setIsWork(0); // isWork为0就不是班主任
List<TeacherInfo> teachers = teacherInfoService.getTeachers(null); //通过下面配置文件可知，该方法需要传入一个 Map 集合，而我这里传入一个 null
//如果没有可用班主任
if (teachers.size() == 0 || teachers == null) {
teacher.setTeacherId(classInfo.getTeacher().getTeacherId());
teacher.setTeacherName("暂无剩余教师");
teachers.add(teacher);
}
model.addObject("teachers", teachers);
model.addObject("grades", grades);
return model;
}
映射文件
Statement会接收一个 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">
<!-- 教师对象 -->
<parameter property="teacher" resultMap="getTeacherResultMap"/>
<!-- 起始位置索引 -->
<parameter property="startIndex" resultMap="getTeacherResultMap"/>
<!-- 每页显示数据量 -->
<parameter property="pageShow" resultMap="getTeacherResultMap"/>
</parameterMap>
<!-- 使用 paramenterMap 查询 -->
<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()方法我传入的是 null，那么，在下面进行条件判断的时候并不能找到 teacher、startIndex、pageShow，所以抛出异常
-->
<where>
<if test="teacher != null">
isWork=#{teacher.isWork}
</if>
</where>
<if test="startIndex != null and pageShow != null">
LIMIT #{startIndex}, #{pageShow}
</if>
</select>
总结
通过之前犯过类似的错误，以及这次错误，我发现 今后只要是 Parameter index out of range (1 > number of parameters, which is 0) 类似的错误大致定位在 映射文件和调用方法传入参数，
映射文件
如果使用了 parameterMap, resultMap，或是返回集合，就要检查参数名称和属性名称是否一致
调用方法
针对使用了 parameterMap 或 parameterType，需要检查传入Map中的键是否存在、匹配，或传入对象是否存在指定属性
下面看下在数据库中遇到Parameter index out of range 错误该如何处理？
最近学ssm框架的时候，遇到了这个错误，找了半天的原因，最后发现原来是sql语句中多了一对单引号。传入值的类型为String类型，就以为还要加引号以表示传入的是字符串，其实是错的，还是初学对其还不太了解。
如下：
错误的：
<update id="updateState" parameterType="java.lang.String">
UPDATE login SET State = 0 WHERE LID = '#{value}'
</update>
正确的：
<update id="updateState" parameterType="java.lang.String">
UPDATE login SET State = 0 WHERE LID = #{value}
</update>
