环境：  
Spring Framework 4.3.7.RELEASE  
Servlet 3.1.0  
JDK 1.8

这里的xml版，是指spring的配置使用xml

创建maven webapp项目：maven-spring-webmvc-xml  项目结构如下：

![Center][]

各文件代码如下：  
pom.xml

    @RestController
    public class IndexController {
    
    	@GetMapping("/index")
    	public String index(){
    		return "hello index";
    	}
    }

applicationContext.xml

最后，在项目的跟目录执行mvn clean jetty:run 运行项目
