Servlet.init() für Servlet Spring-Dispatcher warf Ausnahme (XmlBeanDefinitionStoreException)

Question

Okay, so arbeite ich zum ersten Mal auf Feder mvc und ich weiß nicht, wie Sie diesen Fehler beheben. Ich versuche, aus einem einfachen mvc Programm

hier ist meine Datei 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" xmlns:web="http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" 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>FirstSpringMVCProject</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> 

hier ist meine Feder-Dispatcher-servlet.xml

<beans xmlns="https://www.springframework.org/schema/beans" 
     xmlns:xsi="https://www.w3.org/2001/XMLSchema-instance" 
     xsi:schemaLocation="https://www.springframework.org/schema/beans 
     https://www.springframework.org/schema/beans/spring-beans-2.5.xsd"> 

    <beans id="HandlerMapping" class="org.springframework.web.servlet.handler.BeanNameUrlHandlerMapping"/> 
    <beans name="/welcome.html" class="com.rohit.hellocontroller.HelloController"/> 

    <beans id="viewResolver" class ="org.springframework.web.servlet.view.InternalResourceViewResolver"> 

     <property name="prefix">    
      <value>/WEB-INF/</value> 
     </property> 

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

    </beans> 
</beans> 

finden meine hallo controller.java

package com.rohit.hellocontroller; 

import javax.servlet.http.*; 

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

public class HelloController extends AbstractController { 


    @Override 
    protected ModelAndView handleRequestInternal(HttpServletRequest arg0, 
      HttpServletResponse arg1) throws Exception { 

     ModelAndView modelview= new ModelAndView("HelloPage"); 
     modelview.addObject("welcomeMessage","Hi there user this is my own written message"); 

     return modelview; 
    } 

} 

und die letzte ist hellopage.jsp

Answer 1

Sie bean-Tag statt beans Tag verwenden, sollten Sie in Ihrem spring-dispatcher-servlet.xml-Datei.
