javaweb项目的lib中没有放jar包，为什么部署到tomcat后，在lib下有jar包呢？

Question

Answer 1

Haha, guys, use Eclipse. Pay attention to your project. There is a "Java EE6 Libraries", which is a Java EE library that Eclipse automatically adds for you when you create a Web Project. It will automatically copy to the tomcat directory for you.

The web project you created is automatically imported. Look at the names of the jar packages and Baidu to find out the specific contents.

Answer 4

This is the jar package that eclipse automatically imports based on the project you built

Answer 5

This is the function of IDE. You should be using MyEclipse, which comes with JavaEE6 library, which is some jar packages related to Java WEB development.

IDE It will automatically introduce these jar packages for you, and the jar packages in your own lib should be placed in the external jar packages that are not provided by the IDE. The external jar packages that you imported manually
