如何解决UTF-8在java中 [英] How to solve UTF-8 in java

问题描述

我目前使用

 <％@ page language =javacontentType =text / html; charset = UTF -8pageEncoding =UTF-8％> 
 
 
  $ b  
 
 
当我使用 request.getParameter（...）; 从文本框中获取数据时，它会检索像ÉÉ？ öİ。我看到这个问题，当我使用字符不是英语字符。我在tomcat中将 URIEncoding =UTF-8添加到 server.xml 。但它检索了同样的（ÉÉÉÉÉÉÉÉÄÄ°）。如何解决？
 
 
 
谢谢

感谢您的回答。 
 
 
 
以下是我所做的：
 
 
 
 
 
 
我在server.xml中添加了< Connector URIEncoding =UTF-8... />  
 
 
 
 < meta ... charset = utf-8> 标记正常，我尝试 request.setCharacterEncoding（UTF-8）;  
 
 
 
我也试过了< filter> 在web.xml中的标记
 
 
 
 
 
这些操作都无法解决问题。我想知道这是否有其他错误...（记住：我使用< form method ='post'> 。点击提交按钮，当我使用 request.getParameter（..）获取数据的格式不正确。
 
 
 
执行以下操作：
 
 
 
 1）HTML代码
 < meta contentType =text / html; charset =UTF- 8/> 
  
 2）IE 
的浏览器设置View  -  Encoding  - Unicode（UTF-8）
 
 
 
 3）Tomcat服务器
 server.xml  - 在连接器标记中添加了URIEncoding属性
 < Connector port =8080protocol =HTTP / 1.1
 connectionTimeout =20000
 redirectPort =8443URIEncoding =UTF-8/> 
  
 catalina.sh/catalina.bat  - p> 
 
 
  set JAVA_OPTS =  -  Xms256m -Xmx1024m -Xss268k -server -XX：MaxPermSize = 256m -XX：-UseGCOverheadLimit -Djava.awt。 headless = true -Djavax.servlet.request.encoding = UTF-8 -Dfile.encoding = UTF-8 
 
 set CATALINA_OPTS = -Dfile.encoding =UTF-8
  
 4）MIME类型的响应应该是application / x-www-form-urlencoded
 
I currently use
<%@ page language="java" contentType="text/html; charset=UTF-8" pageEncoding="UTF-8"%>
in my jsp page.

And when I get data from textbox using request.getParameter("..."); it retrieves data like that öÉ?É?É?öİ . I saw this problem when I used characters that are not english chars. I add URIEncoding="UTF-8" to server.xml in tomcat. But it retrieved the same (öÉ?É?É?öİ). How to solve it?

Thank you

EDIT

Thanks for your answers. I tried a few things, but nothing has fixed the problem.

Here's what I've done:


I added <Connector URIEncoding="UTF-8" .../> in server.xml.
<meta ... charset=utf-8> tag is ok and I tried request.setCharacterEncoding("UTF-8");
I also tried <filter> tag in web.xml


None of these actions fixes the problem. I'm wondering if there's something else wrong with this...(remembering: I used <form method='post'>. I click submit button and when I get data using request.getParameter("..") the format of this data is not the correct format. )
解决方案
UTF 8 should be set at all the layers of the application.

Do following

1) HTML Code
 <meta contentType="text/html; charset="UTF-8"/>
2) Browser Setting for IE
 View -- Encoding -- Unicode (UTF-8)

3) Tomcat Server
 server.xml - In Connector tag added "URIEncoding" attribute as 
<Connector port="8080" protocol="HTTP/1.1" 
           connectionTimeout="20000" 
           redirectPort="8443" URIEncoding="UTF-8"/>
catalina.sh/catalina.bat - added following  
set JAVA_OPTS=--Xms256m -Xmx1024m -Xss268k -server -XX:MaxPermSize=256m -XX:-UseGCOverheadLimit -Djava.awt.headless=true -Djavax.servlet.request.encoding=UTF-8 -Dfile.encoding=UTF-8

set CATALINA_OPTS=-Dfile.encoding="UTF-8"
4) MIME type of response should be "application/x-www-form-urlencoded"
