The class in jar cannot be found in spring annotion, causing NoSuchBeanDefinitionException error.

Recently, I was maintaining an old project. As a result, I modified a jar package. After the package is repackaged, the following error occurs when the project is started:

Through analysis, we found that userService is annotated by @ service in spring, and then searched for these classes in xml and initialized beans through context: component-scan. After the experiment, it is found that the new class is put into the old jar by using the rar tool, which indicates that the packaging process is wrong.
You can solve this problem by selecting the "Add directory entries" option during packaging. For example:
