错误信息关键描述

Parameterindexoutofrange(1>numberofparameters,whichis0)

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)
publicModelAndViewpreUpdateClass(@PathVariable("classId")IntegerclassId){
logger.info("预修改班级处理");
ModelAndViewmodel=newModelAndView();
//获取要修改班级
ClassInfoclassInfo=classInfoService.getClassById(classId);
model.setViewName("/admin/classedit");
model.addObject("editClass",classInfo);
Listgrades=gradeInfoService.getGrades();
//获取不是班主任的教师
teacher.setIsWork(0);//isWork为0就不是班主任
Listteachers=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);
returnmodel;
}

映射文件

Statement会接收一个Map集合























SELECTa.*,b.classId,b.classNameFROMTeacherInfoa
INNERJOINClassInfobONa.teacherId=b.teacherId



isWork=#{teacher.isWork}



LIMIT#{startIndex},#{pageShow}

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Parameterindexoutofrange(1>numberofparameters,whichis0)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Parameterindexoutofrange 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：


UPDATEloginSETState=0WHERELID='#{value}'

正确的：


UPDATEloginSETState=0WHERELID=#{value}
