javamall.manager.web是一个聚合工程的子模块，它的父工程是javamall.manager。阅读此篇文章，建议大家先看本站的这篇文章：Java购物商城系统后台管理系统的架构。

下面就是新建javamall.manager.web模块的过程。

第一步：

选中“javamall.manager”右键，依次单击“New”→“Module”。

第二步

在这一步，就和之前的新建pojo、mapper、service不一样了，因为这个是web项目，所以我们需要勾选“Create from archetype”，并且选中下面的“org.apache.maven.archetypes:maven-archetype-webapp”。

然后单击“Next”。

第三步

可以，看到，该模块的Parent（父工程）就是javamall.manager。

填写ArtifactId，内容是：javamall.manager.web。然后单击“Next”

第四步

这步是maven的一些自定义配置，默认即可，我们单击“Next”。

第五步

修改Module name为：javamall.manager.web，默认是javamallmanagerweb，我习惯加个“.”来分隔。

第六步：修改pom.xml文件，代码如下

关于pom的修改，以及依赖关系，可以看下我之前的这张图片

最后，看下web模块，新建成功后的截图吧。
