Java基础 -＞ IDEA使用其他Module中的类,module-info文件

1.创建module-info,. 在包下new一个module-info文件

2.文件中请求使用哪个Module requires ConnectTest;

3.在被请求的Module下同样创建一个module-info文件,出口哪个包(这里是哪个包,不是Module) exports ConnectClass;

4.完成操作之后就可以new出其他Module下的类了

5.附加:创建module-info文件以后,其他的包,例如@Test,也需要在module-info文件中配置指明位置

再次附加:好像直接在标红的代码上修复,添加依赖就可以了:

可以添加junit4的依赖,和junit5的依赖,两个都可以一起用 依赖
