如何利用Java在各种框架下编译Scala项目？本文转载自一位外国开发人员的blog，是一篇利用Java语言在最流行的各种Java框架下调用Scala的项目的教程，从细微入手解决实际问题。

下面是一个教程文件是我在如今最佳或者说最流行的Java框架——Spring、Hibernate/JPA、Wicket、Maven和Intellij IDEA上充分利用Java语言调用Scala的项目，希望能帮助其他的Java程序员使用一个企业级的Scala项目。

在IDE上的设置

首先，下载的IntelliJ IDEA的10.0.x（社区版），因为目前它是最好的Scala的IDE。然后选择File |设置|插件(具体的安装方式请参见本博客中SCALA开发之环境搭建【IntelliJ IDEA】)，选择可用的选项卡来安装Scala插件。

创建Maven项目

在IntelliJ IDEA中，选择文件|新建项目，然后选择Maven的模块创建一个Maven项目。然后修改如下所示的pom.xml。添加所有你需要的设置，建立Scala的汇编语言：
