}
}我断点打在controller里面，没有跑到
console里面报警告是: No mapping found for HTTP request with URI [/spring/hello.do] in DispatcherServlet with name 'springmvc'
里面哪里有问题，望指正

解决方案 »

  1.   

    <servlet-mapping>
      <servlet-name>springmvc</servlet-name>
      <url-pattern>/spring/hello.do</url-pattern>
      </servlet-mapping>
    改成
    <servlet-mapping>
      <servlet-name>springmvc</servlet-name>
      <url-pattern>*.do</url-pattern>
      </servlet-mapping>
