Maven多模块项目和Webapp项目

Question

I have two questions about maven project structure:

1) I am creating a maven multi-module project and would like to know if I can put all the common dependencies of the modules in the parent pom? Is that the right way to do?

2) If I am creating a maven webapp project that contains all web.xml and JSP files, where should the web controllers, listeners and model objects be residing? In a separate maven jar project or in the same webapp project?

Answer 1

1) Read up on the difference between dependencyManagement and dependencies . Putting all common dependencies in the parent POM will work, but it's likely to cause spurious dependencies when you add a new module.

dependencyManagement is recommended. You can specify all versions and exclusions in a central place, and then it's enough to specify groupId and artifactId for each dependency of each module.

2) Java sources directly related to the web layer usually go into the war module (unless you want to reuse them for a different project, then it's better to factor them out into a separate jar ).
