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
我要评论
@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>
以上所述是小编给大家介绍的mabatis错误提示parameter index out of range的处理方法，希望对大家有所帮助
