构建Spring MVC 4的HelloWorld实例。
使用以下技术：
如果您已经熟悉maven使用eclipse 创建项目，请随意跳过第1步。
让我们开始。
Goto File-> New - > Maven Project，
取消选中“使用默认工作区位置”，以防您希望在其他位置创建项目
点击下一步
从选项列表中选择maven web app archetype，单击下一步
提供Group Id，Artifact Id，如上所示的版本，然后单击Finish。更新您的项目
你应该得到如下所示的文件结构
注意：如果您没有在项目结构中看到src/main/java和src/test/java文件夹，请转到Project>Properties>Java BuildPath>Libraries，选择/更改为适当的Java版本，单击确定，您应该现在看到这些文件夹。
由于它是一个maven项目，所有项目依赖关系都可以配置，pom.xml并且maven将自动下载所有相应的依赖项。以下是我们项目的pom.xml。

maven-compiler-plugin这里添加了Maven插件来明确指定我们将要使用的java版本。请注意，它也强制eclipse用于项目的jdk版本。如果不存在，eclipse将jdk-version切换回1.5，这是令人讨厌的。所以请添加它在您的项目pom.xml。import org.springframework.stereotype.Controller;
import org.springframework.ui.ModelMap;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
@Controller
@RequestMapping("/")
public class HelloWorldController {
@RequestMapping(method = RequestMethod.GET)
public String sayHello(ModelMap model) {
model.addAttribute("greeting", "Hello World from Spring 4 MVC");
return "welcome";
}
@RequestMapping(value="/helloagain", method = RequestMethod.GET)
public String sayHelloAgain(ModelMap model) {
model.addAttribute("greeting", "Hello World Again, from Spring 4 MVC");
return "welcome";
}
}
在WEB-INF下创建一个名为views的新文件夹，并添加一个简单的JSP页面welcome.jsp（WEB-INF / views / welcome.jsp），在我们的例子中，它将简单地访问从控制器发送的模型值。
