Keine Zuordnung gefunden für HTTP-Anfrage mit URI [/ Simplexonline /] in DispatcherServlet mit dem Namen 'AppServlet'

Question

Den ganzen Abend versuche ich, ein Problem zu finden, aber nicht. Überarbeitete bestehende Themen hier zu diesem Problem, aber nichts half. Ich änderte <url-pattern>/*</url-pattern> Weg zu <context:component-scan base-package="com.xemyl.simplexonline" /> und in den @Controller -> ("/")

ich denke, Sie müssen Sie mvc Namespace

Versuch,

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

<mvc:annotation-driven/> 

..... 

</beans> 

und

@Controller ("/")

@Controller
