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>

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，如果大家有任何疑问请给我留言，小编会及时回复大家的。在此也非常感谢大家对网站的支持！
