之前写了一个web项目，后面需要对这个项目进行小小的修改，但是又想保留原来的项目。这个时候，我新建了一个web项目，然后把之前项目所需的jar包、三层+Servlet、jsp页面全都复制到新的项目中，启动tomcat之后，请求servlet的时候就抛出了这样的异常。

解决方式：把原来项目的web.xml文件打开，把关于servlet的配置信息全部复制到你新建项目的web.xml中。我的如下

<servlet>
        <servlet-name>CustomerServlet</servlet-name>
        <servlet-class>CRM.Servlet.CustomerServlet</servlet-class>
      </servlet>
      <servlet>
        <servlet-name>FindAllServlet</servlet-name>
        <servlet-class>CRM.Servlet.FindAllServlet</servlet-class>
      </servlet>
      <servlet>
        <servlet-name>EditServlet</servlet-name>
        <servlet-class>CRM.Servlet.EditServlet</servlet-class>
      </servlet>
      <servlet>
        <servlet-name>SaveEditServlet</servlet-name>
        <servlet-class>CRM.Servlet.SaveEditServlet</servlet-class>
      </servlet>
      <servlet>
        <servlet-name>DeleteServlet</servlet-name>
        <servlet-class>CRM.Servlet.DeleteServlet</servlet-class>
      </servlet>
      <servlet>
        <servlet-name>SouServlet</servlet-name>
        <servlet-class>CRM.Servlet.SouServlet</servlet-class>
      </servlet>
    
    
    
    
    
    
      <servlet-mapping>
        <servlet-name>CustomerServlet</servlet-name>
        <url-pattern>/CustomerServlet</url-pattern>
      </servlet-mapping>
      <servlet-mapping>
        <servlet-name>FindAllServlet</servlet-name>
        <url-pattern>/FindAllServlet</url-pattern>
      </servlet-mapping>
      <servlet-mapping>
        <servlet-name>EditServlet</servlet-name>
        <url-pattern>/EditServlet</url-pattern>
      </servlet-mapping>
      <servlet-mapping>
        <servlet-name>SaveEditServlet</servlet-name>
        <url-pattern>/SaveEditServlet</url-pattern>
      </servlet-mapping>
      <servlet-mapping>
        <servlet-name>DeleteServlet</servlet-name>
        <url-pattern>/DeleteServlet</url-pattern>
      </servlet-mapping>
      <servlet-mapping>
        <servlet-name>SouServlet</servlet-name>
        <url-pattern>/SouServlet</url-pattern>
      </servlet-mapping>

完成后重启tomcat，重新请求servlet，就不会有异常了。
