如果你正在使用tomcat，你可以试试他们的utf8编码过滤器（当然把它添加到你的web.xml）。他们的过滤器名为org.apache.catalina.filters.SetCharacterEncodingFilter，或者如果您不想依赖第三方，那么您可以查看他们的源代码并编写自己的源代码，这不是很复杂。

If you're using tomcat, you can try their utf8 encoding filter (add it to your web.xml of course). Their filter is called org.apache.catalina.filters.SetCharacterEncodingFilter, or if you don't want to depend on 3rd party then you can peek at their source code and write your own, it's not very complicated.
