Only a type can be imported. com.rain.bean.LabBean resolves to a package

This error typically occurs when you try to import a package instead of a specific class. To resolve this issue, make sure you are importing the correct class instead of the entire package.

For example, if you have a class called `LabBean` inside the package `com.rain.bean`, you should import it like this:

import com.rain.bean.LabBean;

Make sure that the class `LabBean` exists in the specified package and that the package is correctly defined in your project.
