Spring MVC Samples中的“Hello World”来自哪里？(Where is the “Hello World” coming from in Spring MVC Samples)

 我试图从git中查看Spring Show Case中的代码 
 
 https://github.com/SpringSource/spring-mvc-showcase 
 
 但是如果你点击简单的链接，我会在第一页上遗漏一些东西，你会得到绿色的“Hello World”。 
 
 所以我查看了JSP页面，发现了这段代码： 
 
<ul>
            <li>
                <a id="simpleLink" class="textLink" href="<c:url value="/simple" />">GET /simple</a>
            </li>
            <li>
                <a id="simpleRevisited" class="textLink" href="<c:url value="/simple/revisited" />">GET /simple/revisited</a>
            </li>
        </ul>
 
 对控制器的调用在哪里，但我没有看到JSP页面如何知道将“Hello World”置于绿色的位置。 
 
 然后我审查了控件，我发现： 
 
@Controller
public class SimpleController {

    @RequestMapping("/simple")
    public @ResponseBody String simple() {
        return "Hello world!";
    }

}
 
 其中“Hello World”出现在JSP中，但JSP如何知道放在哪里？ 我看不到任何标签 

I am trying to review the code in Spring Show Case from git
 
https://github.com/SpringSource/spring-mvc-showcase
 
But I am missing something on the first page if you click on the simple link you get back "Hello World" in green. 
 
So I looked in the JSP page and I found this code:
 
<ul>
            <li>
                <a id="simpleLink" class="textLink" href="<c:url value="/simple" />">GET /simple</a>
            </li>
            <li>
                <a id="simpleRevisited" class="textLink" href="<c:url value="/simple/revisited" />">GET /simple/revisited</a>
            </li>
        </ul>
 
Where does the call to the contoller but I dont see how the JSP page knows where to put the "Hello World" in green.
 
I then reviewed the control and I found:
 
@Controller
public class SimpleController {

    @RequestMapping("/simple")
    public @ResponseBody String simple() {
        return "Hello world!";
    }

}
 
Which sents the "Hello World" out to the JSP but how does the JSP know where to put it? I dont see any tag
