使用Spring Tool Suite(STS)和Tomcat v8.0,我按照this教程学习并获得了一些关于Spring的知识。我的目的是展示一个简单的" Hello World"什么的,从那里开始。
这是我的代码。大多数这些文件是在启动项目时自动创建的:
HomeController.java :
public class HomeController {
private static final Logger logger = LoggerFactory.getLogger(HomeController.class);
/**
* Simply selects the home view to render by returning its name.
*/
@RequestMapping(value = "/", method = RequestMethod.GET)
public String home(Locale locale, Model model) {
logger.info("Welcome home! The client locale is {}.", locale);
Date date = new Date();
DateFormat dateFormat = DateFormat.getDateTimeInstance(DateFormat.LONG, DateFormat.LONG, locale);
String formattedDate = dateFormat.format(date);
model.addAttribute("serverTime", formattedDate );
model.addAttribute("welcomeMessage", "Spring MVC trial: Welcome!");
return "home";
}
}
针对home.jsp :
<%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c" %>
<%@ page session="false" %>
<html>
<head>
<title>Home</title>
</head>
<body>
<h1>
Hello world!
</h1>
<P> The time on the server is ${serverTime}. </P>
<P> ${welcomeMessage} </P>
</body>
</html>
的web.xml :
<?xml version="1.0" encoding="UTF-8"?>
<web-app version="2.5" xmlns="http://java.sun.com/xml/ns/javaee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

我与本教程的唯一不同之处在于使用了Tomcat v8.0服务器。
问题:
这是内部浏览器的结果,设置为(默认情况下,在运行项目时):
http://localhost:8080/spring/WEB-INF/views/home.jsp
这是我在运行项目时获得的。从我从日志中收集到的内容,服务器运行正常。
但是,根据教程,我应该得到一个:
"Welcome home! The client locale is XXXXX"
在控制台日志中,我没有看到。
我做错了什么?
答案 0 :(得分:2)
您的请求应为http://localhost:8080/{applicationname}
return "home"
您的HomeController
将会自动调用名为home.jsp
如何查找http请求的真实应用程序名称?
所以浏览器网址现在是http://localhost:8080/mvc
