jsp不以正确的格式传递UTF-8数据 [英] jsp not passing UTF-8 data in proper format
问题描述
我想要JSP页面支持UTF8数据我可以使用struts2和jsp本地化，但是当我从本地语言的jsp从用户采取数据时，信息不会以正确的格式进行操作，它传递一些grabled数据。
这是我的jsp代码：------
I want JSP pages to support UTF8 data I am able to localization with struts2 and jsp but when I take data from user on jsp in local language the information is not going in action in proper format it is passing some grabled data. Here is my jsp code :------
<%@ page language="java" contentType="text/plain; charset=UTF-8"
pageEncoding="UTF-8"%>
<%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c" %>
<%@page import="java.util.*"%>

推荐答案
页面中指定的字符编码web.xml）应用于HTTP通信的以下阶段：
The character encoding specified in the page (or in the web.xml) is applied to the following phases of an HTTP communication:
- 准备/从客户端向服务器发送请求
-
-
在服务器中接收/读取请求 - 准备从服务器到客户端的响应
- 在客户端接收/读取响应
应用服务器只需负责第2阶段。
您需要查找您的特定应用程序服务器设置，以更改默认字符编码（可以轻松地 ISO-8859-1 ），并将其更改为 UTF-8 。
You need to look for your specific application server settings, to alter the default character encoding (that could easily be ISO-8859-1), and alter it to work in UTF-8.
例如，在Tomcat中，您需要编辑 conf / server.xml 文件，方法是添加 URIEncoding =UTF-8 / code>的 / code>参数，例如从
For example, in Tomcat you would need to edit the conf/server.xml file, by adding the URIEncoding="UTF-8" parameter to the <Connector>, for example from
<Connector port="8090" />
到
<Connector port="8090" URIEncoding="UTF-8"/>
在Apache Wiki中有一个很好的列表，要检查，以确保所有的组件都以UTF-8运行：
In the Apache Wiki there is a nice list of things to check to make sure all your components are running in UTF-8:
你能推荐什么才能使一切正常？ （如何使用UTF-8
无处不在）。
使用UTF-8作为一切的字符编码是一个安全的赌注。
这几乎适用于所有情况。
Using UTF-8 as your character encoding for everything is a safe bet. This should work for pretty much every situation.
为了完全切换到使用UTF-8，你需要使
：
In order to completely switch to using UTF-8, you need to make the following changes:
- 在server.xml中设置URIEncoding =UTF-8。参考文献： HTTP
连接器，
AJP
连接器。 - 使用字符编码过滤器和
默认编码设置为UTF-8 - 更改所有JSP以在其contentType中包含字符集名称。例如，对于通常的JSP页面使用
<％@ page contentType =text / html; charset = UTF-8％>
，对于XML语法中的页面，c $ c>< jsp：directive.page
contentType =text / html; charset = UTF-8/>
- 更改所有servlet以设置响应的内容类型，并将内容类型中的charset名称包含为UTF-8。使用
response.setContentType（text / html; charset = UTF-8）或
response.setCharacterEncoding - 更改您使用的任何内容生成库（Velocity，Freemarker等）使用UTF-8并指定UTF-
- 在您的字符编码过滤器或jsp页面有机会设置之前，禁用任何可能读取请求参数的阀门或过滤器
编码为UTF-8。有关详细信息，请参阅
http：//www.mail -archive.com/users@tomcat.apache.org/msg21117.html 。
- Set URIEncoding="UTF-8" on your in server.xml. References: HTTP Connector, AJP Connector.
- Use a character encoding filter with the default encoding set to UTF-8
- Change all your JSPs to include charset name in their contentType. For example, use
<%@page contentType="text/html; charset=UTF-8" %>for the usual JSP pages and<jsp:directive.page contentType="text/html; charset=UTF-8" />for the pages in XML syntax (aka JSP Documents). - Change all your servlets to set the content type for responses and to include charset name in the content type to be UTF-8. Use
response.setContentType("text/html; charset=UTF-8")orresponse.setCharacterEncoding("UTF-8"). - Change any content-generation libraries you use (Velocity, Freemarker, etc.) to use UTF-8 and to specify UTF-8 in the content type of the responses that they generate.
- Disable any valves or filters that may read request parameters before your character encoding filter or jsp page has a chance to set the encoding to UTF-8. For more information see http://www.mail-archive.com/users@tomcat.apache.org/msg21117.html.
