HTTP状态500 - 对servlet的弹簧调度Servlet.init（）抛出异常

我学习Spring MVC的，当我试图运行HTML文件也给出了错误HTTP 状态500 - Servlet.init()的servlet的春天-dispatcher抛出异常HTTP状态500 - 对servlet的弹簧调度Servlet.init（）抛出异常

这是我的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>FirstSpringMVC</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>

这是我弹簧调度员的servlet

<?xml version="1.0" encoding="UTF-8"?> 

    <beans xmlns="http://www.springframework.org/schema/beans" 
     xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
xmlns:p="http://www.springframework.org/schema/p"

        http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-2.5.xsd 
        http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-2.5.xsd"> 


    <bean id="HandlerMapping" class = "org.springframework.web.servlet.handler.BeanNameUrlHandlerMapping"/> 

    <bean name = "/welcome.html" class = "com.ankitud.hellocontroller.HelloController"/> 

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

     <property name = "suffix"> 
      <value>.jsp</value> 
     </property> 
    </bean> 
</beans>

这是我的jsp页面

<html> 
    <head> 
     <title>First MVC Application</title> 
    </head> 
    <body> 

    <h1>First MVC Application</h1> 
    <h2>${welcomemessage}</h2>  

    </body> 
</html>

这是我的HelloController类

package com.ankitud.hellocontroller; 

import javax.servlet.http.HttpServletRequest; 
import javax.servlet.http.HttpServletResponse; 

import org.springframework.web.servlet.ModelAndView; 
import org.springframework.web.servlet.mvc.AbstractController; 

public class HelloController extends AbstractController { 

    @Override 
    protected ModelAndView handleRequestInternal(HttpServletRequest request, HttpServletResponse response) throws Exception{ 

     ModelAndView modelandview = new ModelAndView("HelloPage"); 
     modelandview.addObject("welcomemessage", "Hi User, welcome to the first Spring MVC application"); 

     return modelandview; 

    } 

}

这是我得到

javax.servlet.ServletException: Servlet.init() for servlet spring-dispatcher threw exception 
org.apache.catalina.authenticator.AuthenticatorBase.invoke(AuthenticatorBase.java:502) 
    org.apache.catalina.valves.ErrorReportValve.invoke(ErrorReportValve.java:79)

我一起工作的例外Eclipse 4.5.1，Tomcat 8.0.30和Spring 4.2.3。

这是整个堆栈，或者你有在日志下面这个根源栈？ – Berger

您错过了你的web.xml文件这块尝试添加它：

<web-app...> 

    <!-------- DispatcherServlet definition goes here-----> 
    .... 
    <context-param> 
    <param-name>contextConfigLocation</param-name> 
    <param-value>/WEB-INF/spring-dispatcher-servlet.xml</param-value> 
    </context-param> 

    <listener> 
    <listener-class> 
    org.springframework.web.context.ContextLoaderListener 
    </listener-class> 
    </listener> 
</web-app>

它帮助在摆脱误差HTTP状态500 - Servlet.init（），但现在我得到 “HTTP状态404 - /FirstSpringMVC/welcome.html 型状态报告消息/FirstSpringMVC/welcome.html 描述请求的资源不可用。“ 这个错误。 –

@Ankit Jain尝试在这里指定正确的URL：/也许使用*像/*，为什么你有 .jsp但在url中你有welcome.html？ – Abdelhak

我试过/*，但它仍然无效。 Welcome.html经由结合HelloContoller最终其HelloPage.jsp其在端部正在显示。其实我正在通过YouTube教程学习Spring MVC，并遵循他们正在做的事情，这就是我所理解的，如果我错了某处，请纠正我。 –
