手把手教你一个maven的war项目如何引用另外一个war项目
我们都知道一个war项目可以部署到服务器，pom文件里面可以引用许多依赖jar包。但是默认的都是jar类型的，如果一个大的web项目，分模块开发，我想一个war项目引用一个另外一个war项目的jap，css和.class文件，这个可以么？？？答案是肯定的，不过需要一些特殊的配置。需求知道了，好，直接上代码！！！
1，首先创建两个war类型的maven项目。一个普通的jar类型的maven项目（忽略报错，其实里面啥都没错，就是显示x，不用管）
2，
需要在子war项目的pom和父war项目的pom文件中配置一下
这里科普一下，因为jar类型会把class文件依赖进去，而不会把jsp这些文件依赖进去，war类型的反之，所以，需要配置一下，把war文件配置成既是war又是jar的maven项目。父项目不用管，只管需要引入的子war项目，需要在子war项目里面再写一个pom-war.xml文件，大致和pom.xml一样，只需要稍微改动，可以复制pom然后修改即可。

然后再world项目中新建jsp文件
最后，更新maven项目，把fu项目部署到tomcat。
你会发现，world的jsp文件都进来了
注意，这里主要运用了maven的插件。下面把插件的功能说明一下： 主要看注释部分
