**org.apache.ibatis.binding.BindingException: Invalid bound statement (not found)** 问题，即在mybatis中dao接口与mapper配置文件在做映射绑定的时候出现问题，简单说，就是接口与xml要么是找不到，要么是找到了却匹配不到。

# 一、背景描述 #

# 二、问题的本质 #

dao层(又叫mapper接口)跟mapper.xml文件没有映射。

# 三、问题的原因 #

**出现 Invalid bound statement(not found) 错误的可能原因有以下几种：**

> **1、检查 xml 文件所在的 package 名称是否与 Mapper interface 所在的一致；**
> 
> **2、Mapper.xml 的 namespace 写的是否有问题？这个要特别注意哦；**
> 
>     <mapper namespace="com.iot.back.brain.platform.tunnel.database.UserMapper">
> 
> **3、UserMapper 的方法是否在 UserMapper.xml 中，如果没有也会报此错误；**
> 
> **4、UserMapper 的方法中的返回值是 List<User>，而 select 语句中没有正确配置 ResultMap，或者只配置了 ResultType 等；或者 sql 语句是否写的有问题；**
> 
> **5、检查一下，mapper 的 xml 配置路径是否正确：**
>

> 
> **6、单词拼写错误，比如漏写、少写、多写一个字母....等等；**
> 
> **7、属性类型要与数据库类型要匹配，并且数据内容长度要符合，否则也会报错；**
> 
> **8、如果你确认没有以上的问题，那么请任意修改下对应的 xml 文件，比如：增加一个空行，或者删除一个空行，保存，然后重启服务，再试一下。**

# 四、解决方法 #

> **重要说明：重复检查以上几个原因。**

完结！
