Tomcat 8 - 请求的资源不可用
在java春天尝试自我，我一直试图打开页面＆＃34;问候＆＃34;并给我404，而默认页面＆＃34;索引＆＃34;正在加载。请你帮忙。
localhost：8080 / index.jsp - work
localhost：8080 /问候 - 不工作
这里是项目结构：
的web.xml
<web-app>
<servlet>
<servlet-name>DemoMavenServlet</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<init-param>
<param-name>ContextConfigLocation</param-name>
<param-value>/WEB-INF/config/servlet-config.xml</param-value>
</init-param>
</servlet>
<servlet-mapping>
<servlet-name>DemoMavenServlet</servlet-name>
<url-pattern>/</url-pattern>
</servlet-mapping>
<display-name>Archetype Created Web Application</display-name>
</web-app>
servlet的config.xml中
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:mvc="http://www.springframework.org/schema/cache"

<bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<property name="prefix" value="/WEB-INF/jsp/"></property>
<property name="suffix" value=".jsp"></property>
</bean>
</beans>
java controller：
@Controller
public class HomeController {
@RequestMapping(value = "/greeting")
public String sayHello(Model model){
model.addAttribute("greeting", "Hello World");
return "Hello";
}
}
的hello.jsp
<%@ page contentType="text/html;charset=UTF-8" language="java" %>
<html>
<head>
<title></title>
</head>
<body>
<h1>${greeting}</h1>
</body>
</html>
更新2。 现在，当我加入localhost：8080 /问候页面时，我发现了这个问题：
消息：实例化servlet类org.springframework.web.servlet.DispatcherServlet
时出错说明：服务器遇到内部错误，无法完成此请求。
例外

伙计们，我已经摧毁了一些网络服务器（tomcat）。在项目结构领域＆＃34;问题＆＃34;我有6个缺少库的问题我在IntelliJ Idea工作。添加它们并运行项目我的白页后，在这里记录：

更改您的Controller方法以返回hello，如下所示：
@RequestMapping(value = "/greeting")
public String sayHello(Model model){
model.addAttribute("greeting", "Hello World");
return "hello";
}
文件名称区分大小写，Hello和hello不同。

试试这个
返回字符串区分大小写，将在/ WEB-INF / jsp /
中查找相应的jsp@Controller
public class HomeController {
@RequestMapping(value = "/greeting")
public String sayHello(Model model){
model.addAttribute("greeting", "Hello World");
return "hello";//this would resolve to /WEB-INF/jsp/hello.jsp
}
}
答案 2 :(得分：0)
localhost:8080/greeting根本不起作用。首先，如其他答案所述，更改从 Hello 返回 hello ，如下所示：
@Controller
public class HomeController {
@RequestMapping(value = "/greeting")
public String sayHello(Model model){
model.addAttribute("greeting", "Hello World");
return "hello";
}
}
然后找到您的网络应用程序的Context，通常是应用程序的名称，否则您可以按照以下步骤查看它：
- 右键点击
Project选择Properties标签。 - 然后转到
Web Project Settings，您会在那里找到Context root您的申请。
假设您的上下文根 demomaven ，请尝试使用网址：localhost:8080/demomaven/greeting
