When creating a package under resource, there is no Package when right-clicking resource+new, only Directory
We can also use Directory to create a package, but the way of writing is different from the way of creating a package under Package
For example:
Create package in directory
while we were looking at the files
If you use (com.dao.mapper) to create a package, there will be no multi-level directory, which is equivalent to com.dao.mapper.
package name
Correct way of writing:
（com/dao/mapper)
Using (com/dao/mapper) will generate a multi-level directory
In this way, the multi-level directory can also be displayed in the compiler
Notice:
If the package is created in the directory, if the wording is wrong, the file cannot be found when running the project
The following is the problem I encountered when running a project https://blog.csdn.net/m0_67930426/article/details/131364734?spm=1001.2014.3001.5501
