Question

我想从jsp页面的查询字符串中获取utf-8数据，因此我编写了以下简单的JSP页面

但我得到的是garbaage而不是utf-8数据。

我想知道如何从JSP

中的查询字符串中获取utf-8数据

<%@ page language="java" contentType="text/html; charset=UTF-8"
    pageEncoding="UTF-8"%>
<%@ page import="java.sql.*"%>
<%@ page import="java.util.*"%>
<%@ page import="java.util.Random.*"%>
<%
request.setCharacterEncoding("UTF-8");
String strFirstName=request.getParameter("firstname");
String strLastName=request.getParameter("lastname");
String strEmail=request.getParameter("email");
String strPassword=request.getParameter("password1");

out.println("<br/>First Name => "+strFirstName);
out.println("<br/>Last Name => "+strLastName);
out.println("<br/>Email => "+strEmail);
out.println("<br/>Password => "+strPassword);


Connection conn;
conn=null;
int rs;
int Flag=0;

String Query=null;
PreparedStatement stat = null;

Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");
conn = DriverManager.getConnection("jdbc:odbc:xe","system","mypassword"); 

Random randomGenerator = new Random();
int ID = randomGenerator.nextInt();


String sql =" INSERT INTO CONTACTS (id,firstname,lastname,email,password1) VALUES (?,?,?,?,?) ";

stat = conn.prepareStatement(sql);

stat.setInt(1,ID);
stat.setString(2,strFirstName);
stat.setString(3,strLastName);
stat.setString(4,strEmail);     
stat.setString(5,strPassword);

rs=stat.executeUpdate();

您可能正在获取ISO-8859-1编码数据，因为您的表单method是get，而您的WAS（可能是Tomcat？）正在解码URI（这是默认值）。

如果您使用的是Tomcat，请更改HTTP端口的server.xml的Connector元素以包含属性URIEncoding="UTF-8"。

如果您的表单应该更改服务器的状态（例如在数据库中注册联系人），您可以将方法更改为post，默认为请求页面的编码（是utf-8）。
