JSP中将数据存入数据库的时候乱码。将网页的编码方式用GB2312或者UTF-8都是乱码
用的是JDBC的连接方式连接的数据库。具体的代码如下
第一页gengxin.jsp
<%@ page language="java" contentType="text/html; charset=GB2312"
pageEncoding="GB2312"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<%
request.setCharacterEncoding("GB2312");
%>
添加商品信息
添加新商品信息
商品编号:
商品类别:
商品名称:
商品价格:
商品数量:
第二页 转码的
<%!public String Bytes(String str) {
try {
String strOld = str;
byte[] strNew = strOld.getBytes("GB2312");
String bytes = new String(strNew);
return bytes;
} catch (Exception e) {
}
return null;
}%>
第三页
<%@ page language="java" contentType="text/html; charset=GB2312"
pageEncoding="GB2312"%>
<%@ page import="java.util.*"%>
<%@ page import="java.sql.*"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<%
request.setCharacterEncoding("GB2312");
