空ModelAndView返回到DispatcherServlet

我試圖運行我的Web應用程序使用Spring，Hibernate和Apache瓷磚。看來代碼沒有錯誤，但我只是得到一個404頁面。空ModelAndView返回到DispatcherServlet

/var/log/tomcat7/catalina.out：

DEBUG: org.springframework.web.servlet.DispatcherServlet - Servlet 'dispatcher' configured successfully 
DEBUG: org.springframework.web.servlet.DispatcherServlet - DispatcherServlet with name 'dispatcher' processing GET request for [/example/index.html]

的Servlet：

<servlet> 
    <servlet-name>dispatcher</servlet-name> 
    <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class> 
    <init-param> 
     <param-name>contextConfigLocation</param-name> 
     <param-value>classpath:/META-INF/spring/dispatcher-servlet.xml</param-value> 
    </init-param> 
    <load-on-startup>1</load-on-startup> 
</servlet> 

<servlet-mapping> 
    <servlet-name>dispatcher</servlet-name> 
    <url-pattern>/</url-pattern> 
</servlet-mapping>

上下文：

<mvc:annotation-driven /> 
<tx:annotation-driven />

在添加所有休眠的東西之前，我嘗試了網絡應用程序，它工作得很好。但是沒有數據庫的webapp是什麼？

我已經花了這個時間，只是不能找到問題...

UPDATE

控制器：

package com.example.controller; 

import java.util.Map; 

import org.springframework.stereotype.Controller; 
import org.springframework.web.bind.annotation.RequestMapping; 

@Controller 
@RequestMapping("/") 
public class BlogController { 
    @RequestMapping("/index.html") 
    public String posts(Map<String, Object> map) { 
     return "posts"; 
    } 
}

這個請求（index.html）是否應該通過控制器？或者它只是一個靜態的HTML文件？我看到'沒有找到處理程序方法'，所以如果你試圖使用控制器 - 春天找不到它' – jeff

在'web.xml'中，我看到映射到'/'，你可能是指'/ *'？你想要達到什麼網址？ – nobeh

我們能否看到你的控制器 - 整件事情？ – jeff

我解決它。

有兩種上下文：根（應用寬）和servlet上下文我在根上下文中定義viewResolver，tilesConfigurer，tx:annotation-driven和mvc:annotation-driven。

將它移動到servlet上下文解決了這個問題。

更新我搬到viewResolver，tilesConfigurer，tx:annotation-driven和applicationContext.xml到contextConfigLocation（dispatcher-servlet.xml）

您能詳細說明一下嗎？我也曾在那裏服務過。 – Stephane

嘿，我面臨同樣的問題。請您詳細說明一下，或者示例代碼也可以使用！ – Femina

對不起，很久以前。檢查你的上下文配置。我剛纔提到了所提到的內容。 – dtrunk

mvc:annotation-driven定義嘗試發送，而不是字符串或者

的ModelAndView

您可以將地圖對象作爲參數到ModelandView方法（已經過載）

@Controller 
@RequestMapping("/") 
public class BlogController { 
    @RequestMapping("/index.html") 
    public ModelAndView posts(Map<String, Object> map) { 
     return new ModelAndView("/index.jsp", "status", status); 
    } 
}
