HTTP狀態404請求的源不可用

我還是新的Java和春天，目前我試圖映射「/ buku /」到我的home.jsp，但它似乎does not工作。HTTP狀態404請求的源不可用

HomeController.java

package com.web.buku; 

import java.security.Principal; 
import org.apache.log4j.Logger; 
import org.springframework.security.core.GrantedAuthority; 
import org.springframework.security.core.context.SecurityContextHolder; 
import org.springframework.security.core.userdetails.UserDetails; 
import org.springframework.stereotype.Controller; 
import org.springframework.web.bind.annotation.RequestMapping; 
import org.springframework.ui.ModelMap; 


@Controller 
public class HomeController { 

    private static Logger logger =Logger.getLogger(HomeController.class); 

    @RequestMapping("/") 
    public String home(ModelMap model){ 

     model.addAttribute("message", "Hello Spring MVC Framework!"); 
     return "home"; 
    } 
}

針對home.jsp

<%@ page language="java" contentType="text/html; charset=ISO-8859-1" 
    pageEncoding="ISO-8859-1"%> 
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"> 
<html> 
<head> 
<meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1"> 
<title>Insert title here</title> 
</head> 
<body> 
${message} 
yosh 
</body> 
</html>

的web.xml

我跑我的Tomcat服務器，並嘗試訪問本地主機：8080 /不哭/和它不會工作，不斷給我「HTTP狀態404 - /不哭/」錯誤

嘗試在你的書，servlet.xml中添加<mvc:annotation-driven />掃描控制器

<?xml version="1.0" encoding="UTF-8"?> 
<beans xmlns="http://www.springframework.org/schema/beans" 
    xmlns:context="http://www.springframework.org/schema/context" 
    xmlns:mvc="http://www.springframework.org/schema/mvc" 
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
    xsi:schemaLocation=" 
    http://www.springframework.org/schema/beans  
    http://www.springframework.org/schema/beans/spring-beans-3.0.xsd 
    http://www.springframework.org/schema/context 
    http://www.springframework.org/schema/context/spring-context-3.0.xsd 
    http://www.springframework.org/schema/mvc 
    http://www.springframework.org/schema/mvc/spring-mvc-3.0.xsd"> 

    <context:component-scan base-package="com.web.buku" /> 
    <mvc:annotation-driven /> 
    <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver"> 
     <property name="prefix" value="/WEB-INF/jsp/" /> 
     <property name="suffix" value=".jsp" /> 
    </bean> 

</beans>

不要忘記添加MVC命名空間

更新：我有ALS o注意你沒有指定你的請求方法。 replare @RequestMapping("/")與@RequestMapping(value="/",method=RequestMethod.GET)

感謝您的回覆，但它仍然不能解決問題 – jourpool 2014-12-04 07:34:54

請看我的更新回答 – user3308224 2014-12-04 07:52:54

試過了，仍然沒有解決問題 – jourpool 2014-12-04 08:19:03

嘗試刪除requestMapping註釋上面的方法 - home？

嘗試過它，不工作 – jourpool 2014-12-04 05:25:09

啓動Web服務器時是否顯示任何錯誤？因爲你甚至不能訪問項目基礎根路徑。 – Kenti 2014-12-04 05:37:42

沒有錯誤。仍然不知道原因是什麼 – jourpool 2014-12-04 09:30:01

要將地圖"/book/home"設置爲home.jsp？我想你打算映射/電子書/ home路徑您HomeController的home方法...那就試試下面

@Controller 
public class HomeController { 

    private static Logger logger =Logger.getLogger(HomeController.class); 

    @RequestMapping("book/home") 
    public String home(ModelMap model){ 

     model.addAttribute("message", "Hello Spring MVC Framework!"); 
     return "home"; 
    } 
}

現在，當你點擊的網址：localhost:8080/buku/book/home - 你應該得到的home.jsp顯示

我很抱歉，我的意思是將'/ buku /'映射到home.jsp – jourpool 2014-12-04 07:27:43

@jourpool - 您是否嘗試使用URL：localhost：8080/buku – Arun 2014-12-04 08:20:36

當然，當然是的 – jourpool 2014-12-04 08:26:12
