BindingException: Invalid bound statement (not found)

org.apache.ibatis.binding.BindingException: Invalid bound statement (not found): com...UserInfoMapper.listByRole

报错描述：

程序一直可以正常运行，本次代码修改操作添加了新的依赖，也添加了新的mapper, xml文件。之前一运行所有的数据库查询接口无论新旧都会报这个错误。

网上的百度到的大多方法主要有以下可能：

1、检查xml文件的namespace 是否和Mapper interface 所在的包名类名一致（一般ctrl + 鼠标左键可跳转即没有错误)
namespace-mapper

2、检查Mapper 接口中的方法是否和xml 中一致（包括方法个数，是否重复，方法名称，方法入参，方法返回类型）

3、查看全局的mapper xml 配置路径是否正常（这里使用的是mybatis-plus）
mybatis-xml全局配置

问题现象：所有接口操作表报错（包括新旧方法）；

本次代码变化：添加了多个新的mapper, xml 方法和文件，引入了新的pom依赖；

我是通过source tree 进行git 代码管理的，它有暂存功能（暂存修改-不保留暂存的更改）代码还原后重新启动访问相同旧接口无报错，判断该报错是因为新编写的代码影响的。

source tree暂存

上面说到我们新编写的代码主要有两部分，新的mapper,xml 方法，和新的pom依赖

进一步的判断方式有两种：

a、针对新的mapper,xml 方法针对上面百度到的1，2两点方法进行逐个检查；

b、删除引入新的pom依赖，删除对应依赖类调用直至没有报错，后重新启动应用访问。

由于使用新的依赖并不多直接检查b项，发现应用接口能访问没有报错，至此定位此问题是因为新引入的依赖，查看新引入依赖

发现依赖存在重复并有个是mybatis-plus 依赖（下图project 是新引入依赖，exclusions 去除重复）

引入新的pom依赖

备注

如果上述依赖包去除后还有问题则需要进行a项检查新的mapper,xml；根据方法1，2去进行校验；校验后启动访问，直至没有问题。

最后都无法找到问题，只能全部重写代码，一个个单元测试去跑了。555555

编程规则：永远不要想着一次写完所有代码然后运行(有问题时排查时间会几何增加)，一步一个脚印，尽可能多写单元测试！！！
