用SpringMVC控制器無法與在SprinvMVC章請求

Question

1. 我遵循書中的指示「春天行動」對付

2. 當我運行Tomcat服務器，並嘗試演示它返回錯誤，如：

   HTTP狀態404 - 找不到

   類型狀態報告

   說明原始服務器沒有找到噸當前表示他瞄準資源或不願意透露存在的資源。

我使用的MacOS，tomcat9，的Intellij 2017.1，JDK 1.9 這裏是我的代碼。

web.xml中：

<?xml version="1.0" encoding="UTF-8"?> 
<web-app xmlns="http://xmlns.jcp.org/xml/ns/javaee" 
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
    xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-app_3_1.xsd" 
    version="3.1"> 

<context-param> 
    <param-name>contextConfigLocation</param-name> 
    <param-value>/WEB-INF/applicationContext.xml</param-value> 
</context-param>

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

spitter.xml：

<?xml version="1.0" encoding="UTF-8"?> 
<beans xmlns="http://www.springframework.org/schema/beans"

<!--static resources getting--> 
<mvc:resources mapping="/resources/**" location="/WEB-INF/resources"/> 

<!--use annotations to create the mapping between--> 
<!-- url and class deal with request(Controller) --> 
<mvc:annotation-driven/> 

<!--scan the component and auto regist as bean--> 
<context:component-scan base-package="com.springmvc"/> 

<!--Use this bean to map the jsp file according to the name return by Controller--> 
<!--It will automatically add the prefix and suffix to the name string--> 
<bean class="org.springframework.web.servlet.view.InternalResourceViewResolver"> 
    <property name="prefix" value="/WEB-INF/views/"/> 
    <property name="suffix" value=".jsp"/> 
</bean> 

控制器：

package com.springmvc.controller; 

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

/** 
* Created by xwh on 29/3/2017. 
*/ 
@Controller 
    public class HomeController { 
// public static final int DEAFAULT_SPITTLES_PER_PAGE = 25; 


public HomeController() { 
    System.out.println("-------HomeController init-------"); 
} 

@RequestMapping("/") 
public String showHomePage() { 

    System.out.println("-------showHomePage Method show-------"); 


    return "home"; 
    } 
}

Answer 1

您的contextConfigLocation文件是spitter-servlet.xml嗎？ 在你的web.xml文件中，你定義的上下文配置文件是applicationContext.xml。這意味着您的配置在spitter.xml中不被使用。 嘗試將contextConfigLocation更改爲/WEB-INF/spitter-servlet.xml
