Le préfixe "xsi" pour l'attribut "xsi: schemaLocation" associé à un type d'élément "beans" n'est pas lié. Lors de l'exécution du printemps sur Tomcat

Question

S'il vous plaît aidez-moi à sortir de cette erreur Je ne comprends pas comment puis-je résoudre ce problème?

Voici mon web.xml et les fichiers Dispatcher servlet.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_2_5.xsd" version="2.5"> 

    <display-name>AngSpring</display-name> 
    <welcome-file-list> 
    <welcome-file>index.html</welcome-file> 
    <welcome-file>index.htm</welcome-file> 
    <welcome-file>index.jsp</welcome-file> 
    <welcome-file>default.html</welcome-file> 
    <welcome-file>default.htm</welcome-file> 
    <welcome-file>default.jsp</welcome-file> 
    </welcome-file-list> 


    <display-name>Spring MVC Angular Application</display-name> 

    <servlet> 
     <servlet-name>Dispatcher</servlet-name> 
     <servlet-class> 
     org.springframework.web.servlet.DispatcherServlet 
     </servlet-class> 
     <load-on-startup>1</load-on-startup> 
    </servlet> 

    <servlet-mapping> 
     <servlet-name>Dispatcher</servlet-name> 
     <url-pattern>/*</url-pattern> 
    </servlet-mapping> 

Et Répartiteur-servlet.xml:

<?xml version="1.0" encoding="UTF-8"?> 
<beans xmlns="http://www.springframework.org/schema/beans" 
    xmlns:context="http://www.springframework.org/schema/context" 
    xmlns:aop="http://www.springframework.org/schema/aop" 
    xmlns:mvc="http://www.springframework.org/schema/mvc" 
    xsi:schemaLocation="http://www.springframework.org/schema/beans 
    http://www.springframework.org/schema/beans/spring-beans-3.0.xsd 
    http://www.springframework.org/schema/aop 
    http://www.springframework.org/schema/aop/spring-aop-3.0.xsd"> 

    <mvc:annotation-driven /> 
    <context:annotation-config /> 
    <context:component-scan base-package="com" scoped-proxy="targetClass" /> 


    <bean 
     class="org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter"> 
     <property name="messageConverters"> 
      <list> 
       <ref bean="jacksonMessageConverter" /> 
      </list> 
     </property> 
    </bean> 

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


</beans>

Vous obtenez l'erreur parce que votre préfixe xsi n'est pas lié.
