Build a MAVEN project in idea
Look at the online big god hair of various blogs, and then build up a simple MAVEN-STRTUS2 project for beginners to learn
New Project
The next step is to choose nothing, direct finish
2. Thejar package management in idea is implemented through Pom.xml, and the following is the configuration of the Pom.xml file to add the Struts2 jar package to the project
Many people will be confused about the dependency configuration in Pom.xml, and recommend a website with various jar dependency configurations http://maven.oschina.net/index.html#nexus-search;quick~struts
3. Save the dependent copy to Pom.xml, and idea will automatically download the jar file to the Coorey of your locally installed MAVEN configuration (Jstl package is also added here)
4. start the server that configures the project, add Web support, etc.
After you add a server on, add Web support
5. Next Configure Web.xml,struts.xml, add the action package, and the action class, I'll just paste the code
