サーブレットクラスのインスタンス化エラー。org.springframework.web.servlet.Dispatcherservlet

Question

私はspring 4.0.4 RELEASE.jarを使用していますが、クラスが見つかりませんでした。 ここにここに私のweb.xml

<?xml version="1.0" encoding="UTF-8"?> 
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
xmlns="http://java.sun.com/xml/ns/javaee" 
xsi:schemaLocation="http://java.sun.com/xml/ns/javaee 
http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd" id="WebApp_ID" 
version="3.0"> 
<display-name>SpringMvcApplication</display-name> 
<servlet> 
    <servlet-name>spring-dispatcher</servlet-name> 
    <servlet-class>org.springframework.web.servlet.Dispatcherservlet</servlet-class> 
</servlet> 
    <servlet-mapping> 
<servlet-name>spring-dispatcher</servlet-name> 
    <url-pattern>/</url-pattern> 
    </servlet-mapping> 
</web-app> 

である私のspring-dispatcher-servlet.xmlコード

<beans xmlns="http://www.springframework.org/schema/beans" 
    xmlns:context="http://www.springframework.org/schema/context" 
    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-4.0.xsd 
    http://www.springframework.org/schema/context 
    http://www.springframework.org/schema/context/spring-context-4.0.xsd"> 
<context:component-scan base-package="com.javahash.spring.controller" /> 
     <bean id="HandlerMapping" name="/welcome.html" 
    class="org.springframework.web.servlet.handler.BeanNameUrlHandlerMapping"  /> 
    <bean name="/welcome.html" 
     class="com.manikant.hellocontroller.HelloController"/>  
    <bean id= "viewResolver" 

class="org.springframework.web.servlet.view.InternalResourceViewResolver"> 
      <property name="prefix" value="/WEB-INF/" /> 
     <property name="suffix" value=".jsp" /> 
    </bean> 
</beans> 

そして、ここでスタックトレースです：

Answer 1

お知らせエラーメッセージ：

Error instantiating servlet class org.springframework.web.servlet.Dispatcherservlet 
                      ^

以降スタックトレースに：

java.lang.ClassNotFoundException: org.springframework.web.servlet.Dispatcherservlet 

正しいスペルは大文字SとDispatcherServletです。

Answer 2

長期的な解決策

上記春4.Xとを使用している間、常にそれらによって提供さBill of Materialsを使用することをお勧めします。それは関連する依存関係を引き出し、アプリケーションによって引き起こされるすべての種類のビルドパス/ランタイムエラーを回避するのに役立ちます。あなたのケースでは

、あなたがより多くのスタックトレースを追加でき
