使用springmvc遇到的一些问题

1. org.springframework.web.servlet.PageNotFound noHandlerFound

servlet配置如下：

<servlet>
    <servlet-name>springmvc</servlet-name>
    <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
    <init-param>
      <param-name>contextConfigLocation</param-name>
      <param-value>classpath*:/spring/spring-servlet.xml</param-value>
    </init-param>
  </servlet>
  <servlet-mapping>
    <servlet-name>springmvc</servlet-name>
    <url-pattern>/*</url-pattern>
  </servlet-mapping>

解决方法：servlet-mapping里面的 /* 改为 / 即可。

2. 请求返回错误码：406 Not Acceptable

HTTP Status 406 -
The resource identified by this request is only capable of generating responses with characteristics not acceptable according to the request "accept" headers.

我设置的返回json格式，但是缺少支持包
