1.把传的值保存在encodeURI中，记得是双encodeURI
url:'json/selectUser.action?param='+encodeURI(encodeURI("中文")),
2.在action中解码
HttpServletRequest request = ServletActionContext.getRequest();
String param = request.getParameter("param");
param = URLDecoder.decode(param,"UTF-8");
3.输出param
System.out.println(param);原文链接：https://www.f2er.com/ajax/166127.html
