Invalid bound statement (not found)错误的可能原因

Posted 2023-04-11

参考技术A

Invalid bound statement (not found)这个问题的实质就是 mapper接口和mapper.xml没有映射起来

常见的低智商问题有下列几个：

1.mapper.xml 里面的 namespace与实际类不一样
mapper.xml 里面的 namespace应该是其对应的接口路径。这个有个快捷的检测办法就是按住ctrl键，然后点击namespace里面的包名，如果能跳到对应的类，那就说明没问题。

2.mapper接口的函数名称和mapper.xml里面的标签id不一致
这个问题也很常见，最好的办法还是复制过去，这样可以确保没得问题,1点和2点都是关于拼写错误的情况

3.构建没有进去，请看一下target文件夹下面这些是否存在，没有请重新构建

4.包扫描路径是否正确
检查mybatis的配置是否正确，需要配mapperLocations和typeAliasesPackage属性。
也可以在springboot启动类上面加@MapperScan注解，指定扫描路径

5.配置文件写错
如果你是Mybatis的话请注意yml或者properties文件里面的

如果你是Mybatis plus 这个时候你要注意了，mybatis plus是下面这样的配置,如果你发现1,2,3,4点的问题都没有问题，你需要注意一下这个东西

Mybatis 异常记录: Invalid bound statement (not found)

一般是Mapepr.xml文件中文nameapce没有和mapper接口发生映射，导致mybatis绑定失败

检查namespace 绑定mapper.java的 路径是否正确
