попробуйте этот <контекст: компонент-сканирование base-package = "com.ezmsip. *" /> Insted из – Darshit

Каково имя вашего jsp-файл и то, как вы к этому клонируете? Также покажите свое разрешение. –

@ Darshit Я пробовал с com.ezmsip. * И я все равно получаю ту же ошибку. – Alberto

web.xml Изменить следующим образом:

<context-param> 
    <param-name>contextConfigLocation</param-name> 
    <param-value>/WEB-INF/todo-servlet.xml</param-value> 
</context-param> 

<servlet> 
    <servlet-name>dispatcher</servlet-name> 
     <servlet-class> 
      org.springframework.web.servlet.DispatcherServlet 
     </servlet-class> 
     <init-param> 
      <param-name>contextConfigLocation</param-name> 
      <param-value></param-value> 
     </init-param> 
     <load-on-startup>1</load-on-startup>

Ibrahim, я попытался изменить на , как вы предложили, однако я получаю следующую ошибку: cvc-complex-type.2.4.a: Недействительный контент был найден, начиная с элемента 'context-param'. Один из «{» http: // java.sun.com/xml/ns/javaee":init-param, "http://java.sun.com/xml/ns/javaee":load-on-startup , "http: // java.sun.com/xml/ns/javaee":enabled," http://java.sun.com/xml/ns/javaee":async-supported ", http: // java.sun.com/xml/ns/javaee":run-as, "http://java.sun.com/xml/ns/javaee":security-role-ref", http: // java.sun .com/xml/ns/javaee ": multipart-config} '. – Alberto

@Alberto, ответ был обновлен – Ibrahim

Моя проблема: у меня есть среда Eclipse Neon для работы с JRE вместо JDK. Мне пришлось отредактировать файл инициализации Eclipse и установить оператор -vm, указывающий на путь JDK.
