Key points of SSM configuration based on Java Web project and possible problems and Solutions

I found that some key points were not mentioned when explaining the configuration of Java Web project SSM (spring, spring MVC, mybatis) on the Internet. I will post some important configurations and possible problems for beginners to learn from

1. When creating a new Java Web project, you can select the relevant dependency library or import it with Maven.

2. When importing dependent libraries from outside, remember to import them in war, otherwise the relevant dependent libraries will not be found on the server and packaging will fail.

3. On the web Configuration in XML

4. After scanning the controller in ApplicationContext, you can simply access the interface in the controller

We will continue to follow up mybatis's database configuration later

The above key points of SSM configuration and possible problems and solutions based on Java Web project are all the contents shared by Xiaobian. I hope to give you a reference and support more programming tips.
