【解决HTML标签问题】
<%@ page import="java.net.*, org.apache.commons.lang3.*" pageEncoding="gb2312" %><% int num; try { num = Integer.valueOf(request.getParameter("num")); } catch (NumberFormatException e) { num = 0; } %><!doctype html> <html> <head> <meta charset="gb2312"> <title>简体中文网页</title> </head> <body> <p>Tomcat8中server.xml的<Connector>标签下必须加上URIEncoding="ISO-8859-1", 否则将无法解析GB2312字符串！</p> <p><% String str = request.getParameter("value"); str = new String(str.getBytes("ISO-8859-1"), "gb2312"); str = StringEscapeUtils.escapeHtml4(str); // HTML编码 out.print(str); %></p> <form id="form1" name="form1" method="get"> <input name="value" type="text" id="value" value="<%= str %>"> <input type="submit" value="确 定"> <input name="num" type="hidden" id="num" value="<%= num + 1 %>"> </form> <p><% str = request.getQueryString(); str = URLDecoder.decode(str, "gb2312"); str = StringEscapeUtils.escapeHtml4(str); // HTML编码 out.print(str); %></p> </body> </html> 需要在WEB-INF/lib/文件夹里放入commons-lang3-3.5.jar，下载地址是： http://mirrors.hust.edu.cn/apache//commons/lang/binaries/commons-lang3-3.5-bin.tar.gz 该jar文件位于压缩包内。 这样当URL参数中含有HTML标签时网页也能正常显示： http://localhost:8080/test/get_encoding.jsp?value=%BC%F2%CC%E5%D6%D0%CE%C4%3Cscript%3E&num=10 |
