mapper接口上的形参对象包是不是引用错了, 或者这样说引用对象所在的包里面也就是那个类是不是没有设置无参构造, 所以在构建mapper接口对象的时候, 因为形参构建失败而导致整个mapper类失败

初步怀疑 你使用了jdk 9 的特性，参考如下

module java.base does not "opens java.lang" to module_haoranhaoshi的博客-CSDN博客 1、Java9开始的JDK支持模块化，如果模块A引用模块B，模块A的module-info.java:moudle A { requires B;}但模块B并未加入module-info.java达成模块化，或者未开放外部所需部分，那么就会产生“Unable to make {member} accessible: module {模块A或模块A中的一部分} does not 'op... https://blog.csdn.net/haoranhaoshi/article/details/89975365

楼上+1，看到module就知道你最起码是jdk9，换8省事多了
