get提交
/onlineshoppingcart/servlet/addShoppingCart?id=0001&name=HP笔记本电脑&price=5999.00
public class AddShoppingCartSevlet extends HttpServlet
{
@Override
public void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException
{
String name = request.getParameter("name");
System.out.println(name);
request.setCharacterEncoding("utf-8");
System.out.println(request.getParameter("name"));
doPost(request, response);
}
}
先不说下面的业务处理了,这里打印出来的name就是乱码;
很搞不懂为什么,项目是utf-8编码
html是,request没设置和设置后打印出来也一样。
不晓得为什么get方式提交后出现这样的乱码。
自己寻得的方法,在tomcat的server.xml设置下
<Connector port="8080" protocol="HTTP/1.1" connectionTimeout="20000"redirectPort="8443"
URIEncoding="UTF-8" />
<Connector port="8009" protocol="AJP/1.3" redirectPort="8443"
URIEncoding="UTF-8"/>
加上编码,就正常显示了
在修改tomcat配置前,自己还尝试了下过滤器,过滤内容如下,但是也不行
<filter>
<filter-name>encodingFilter</filter-name>
<filter-class>com.yulei.filter.EncodeFilter</filter-class>
<init-param>
<param-name>encoding</param-name>
<param-value>UTF-8</param-value>
</init-param>
</filter>
