java ssh

String name = request.getParameter("sel");
System.out.println(name);

这是Action 里面写的，在servlet里面已经写上了

response.setContentType("text/html;charset=gb2312");
request.setCharacterEncoding("gb2312");

为什么name输入出来还是"??" ...

在web.xml文件中配置试试

<filter>
<filter-name>Spring character encoding filter</filter-name>
<filter-class>dorg.springframework.web.filter.CharacterEncodingFilter</filter-class>
<init-param>
<param-name>encoding</param-name>
<param-value>GBK</param-value>
</init-param>
<init-param>
<param-name>forceEncoding</param-name>
<param-value>true</param-value>
</init-param>
</filter>

<filter-mapping>
<filter-name>Spring character encoding filter</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>

加上response.setCharacterEncoding("gb2312");

并且都要在

String name = request.getParameter("sel");

这句前面
