试试这个 insted of – Darshit

你的名字是什么jsp文件以及你如何映射到这个文件？请同时显示您的视图解析器。 –

@Darshit我试着用com.ezmsip。*，但仍然得到相同的错误。 – Alberto

更改web.xml如下：

<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> 
</servlet> 

<servlet-mapping> 
    <servlet-name>dispatcher</servlet-name> 
    <url-pattern>/your-mapping/*</url-pattern> 
</servlet-mapping> 

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

易卜拉欣，我试着改变为，正如你所建议的，但是我得到以下错误： cvc-complex-type.2.4.a：从元素'context-param'开始找到无效的内容。其中一个'{“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，答案已更新 – Ibrahim

我的问题是我的Eclipse Neon环境设置为使用JRE而不是JDK运行。我不得不编辑Eclipse的init文件，并设置指向JDK路径的-vm语句。
