所请求的资源（/）不可用

Question

我刚开始学习的Spring MVC 3，我在一开始与运行简单的Hello World程序

我试图让this启动和运行有问题，但我不能因为某些原因

我不断收到此错误

type Status report 

message/

description The requested resource (/) is not available. 

这里是我的servlet-context.xml文件

HomeController.java

包com.test.test;

import org.springframework.stereotype.Controller; 
import org.springframework.ui.Model; 
import org.springframework.web.bind.annotation.RequestMapping; 
import org.springframework.web.bind.annotation.RequestMethod; 


@Controller 
public class HomeController { 

    @RequestMapping(value = "/") 
    public String home() {  
     return "WEB-INF/views/home.jsp"; 
    } 

} 

我使用Tomcat 7

任何人都知道什么是余弦这个错误？

@Tenelope你不必返回"WEB-INF/views/home.jsp";你可以只返回"home"因为你已经在你的servlet上下文配置：

<beans:bean class="org.springframework.web.servlet.view.InternalResourceViewResolver"> 
     <beans:property name="prefix" value="/WEB-INF/views/" /> 
     <beans:property name="suffix" value=".jsp" /> 
    </beans:bean> 

我给你的建议是要下载春源（日食像IDE） ：

http://www.springsource.org/springsource-tool-suite-download

下载它后，你可以简单地去File > New > Spring Template Project > Spring MVC project

完成创建项目后，将为您创建工作模板项目（结构化项目，示例控制器文件，示例视图，pom.xml等）。包括你正在谈论的"/"例子。你可以构建它并将其部署到tomcat或其他任何地方。

这种方式你已经得到工作的例子，你可以从那里拿它。

Btw。检查了这一点：

https://github.com/SpringSource/spring-mvc-showcase/blob/master/MasteringSpringMVC3.pdf?raw=true

这是足以让你开始富裕与Spring MVC的。
