  • count is ambiguous in Mapped Statements collection (try using the full name including the namespace, or rename one of the entries)

    各位老铁们: 遇到这种问题怎么办?

    一般的大家第一时间想到的估计是

    是不是重复了,但是检查了一遍又一遍, count 不是一个sql的 id 啊。 这怎么会报这个错误呢,就开始纠结。

    还有一种庆魁昂可能你没有考虑到:

    Mapper.xml没有配置,或者命名空间错误,系统找不到相关的映射。

    或者你的mapper文件没有在mybatis的中得配置文件 的mapper 标签中得resource 路径中没有。 制定的路径扫描不到。
