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：
|
1
2
3
|
<update id="updatestate" parametertype="java.lang.string"> update login set state = 0 where lid = '#{value}'</update> |
正确的：
|
1
2
3
|
<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服务器之家网站的支持！
