The purpose of setting up Classpath is to tell the Java execution environment in which directories you can find the classes or packages needed by the Java program you want to execute.

Classpath refers to the classes directory under the WEB-INF folder. When the web application is published to the server, the compiled class files and resource files of all the classes under the src directory will be placed into the classes directory under the WEB-INF folder.

The difference between 1.4.Classpath and classpath*

Classpath: only look for files in your class path.

Classpath*: contains not only the class path, but also the jar file (class path) for lookup.

1) the former will only be loaded from the first classpath, while the latter will be loaded from all classpath.

2) if the resource to be loaded is not in the current ClassLoader path, the classpath: prefix cannot be found, in which case you need to use the classpath*: prefix.

3) if a resource of the same name exists in multiple classpath and needs to be loaded, then using classpath: only the first one will be loaded, in which case you also need to use the classpath*: prefix.

4) using classpath*: needs to traverse all the classpath, so the loading speed is very slow, so when planning, you should plan the path where the resource file is located as well as possible and avoid using classpath* as much as possible.
