我刚刚开始学习Spring MVC 3，开始运行简单的hello world程序时遇到了问题

我试图让这个启动和运行，但我不能因为某些原因

我不断收到这个错误

type Status report
message /
description The requested resource (/) is not available.

这是我的servlet-context.xml档案

HomeController.java

打包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";
    }
}

我正在使用Tomcat 7。

有人知道这个错误是什么吗？

回答：

@Tenelope您不需要返回，"WEB-INF/views/home.jsp";您可以返回"home"它，因为您已经在servlet-

context中对其进行了配置：

    <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>

我对您的建议是下载spring源（类似于IDE的Eclipse）：

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

download

下载后，您只需转到 File > New > Spring Template Project > Spring MVC project

创建完项目后，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"/"您正在谈论的示例。您可以构建它并将其部署到tomcat或其他任何东西。

这样，您已经获得了有效的示例，您可以从那里获取它。

顺便说一句。看一下这个 ：

https://github.com/SpringSource/spring-mvc-

showcase/blob/master/MasteringSpringMVC3.pdf?raw=true

这足以使您开始使用Spring MVC。
