Spring MVC Project Export jar package does not recognize normal mapping issues

The author of the code is very simple, the usual configuration file, Web. Xml as follows

 <servlet>       <!--name -       <Servlet-name>Springmvc</Servlet-name>       <!--servlet class -       <Servlet-class>Org.springframework.web.servlet.DispatcherServlet</Servlet-class>          <Init-param>           <!--SPRINGMVC location of configuration parameter files -           <Param-name>Contextconfiglocation</Param-name>           <!--The default name is Servletname-servlet.xml -           <Param-value>Classpath*:springmvc-servlet.xml</Param-value>       </Init-param>       <!--start sequence, the smaller the number, the earlier the start -       <Load-on-startup>1</Load-on-startup>           </servlet>   <!--all requests will be intercepted by Springmvc . -   <servlet-mapping>       <Servlet-name>Springmvc</Servlet-name>       <Url-pattern>/frontend/*</Url-pattern>   </servlet-mapping>

MyEclipse development project, according to the normal method right-click Project Export-->jar but cannot execute.

The @controller on the web said the annotations could not work in jars, and later found the answer in StackOverflow:

Spring annotation-based Controllers not working if it is inside Jar file

Workaround: When exporting the jar file, tick the following: Add directory entries check box

When you export the jar file using the Export utility in eclipse there is a option called Add directory entries. Check this option and export the jar file, this would solve the problem.
