在servlet设置 response.setContentType("text/html;charset=GBK");ajax 才能取得中文
在server.xml的
<Connector port="80" maxHttpHeaderSize="8192" maxThreads="150" minSpareThreads="25" maxSpareThreads="75" enableLookups="false" redirectPort="8443" acceptCount="100" connectionTimeout="20000" disableUploadTimeout="true" URIEncoding="GBK" /> 加上红色那段
ajax才能传中文到普通页面, 通过request.getParameter(name)取得.
