tomcat的字符编码问题 [英] Character encoding problems with tomcat

问题描述

我遇到了网络应用程序的字符编码问题。有一个弹出窗口用用户输入查询数据库（按名称搜索某人）。问题是重音字符正在转换成奇怪的字母，如ó=> ó。这是一个很标准的问题，但我不知道发生了什么。

I'm having trouble with character encoding for a web application. There is a pop up that queryes the database with user input (search a person by name). The problem is that accented characters are being transformed into weird letters like ó => ó. This is a pretty standard problem but I can't figure out what is going on.

我做了什么？

主要按照

Mainly, follow this.

• 在我的tomcat的第一个过滤器设置（request& ; response.setCharacterEncoding（UTF-8）;


• 设置每个 web.xml server.xml 字符encodign参数<？xml version ='1.0'encoding ='utf-8'？> 。


• 在连接器中将URIEncoding更改为UTF-8。使用firebug，我已经看到内容类型设置为 text / html;


• 将jsp的元类型和@page更改为UTF-8。
li>

• Setting at the first filter on my tomcat (request&response).setCharacterEncoding("UTF-8");
• Setting every web.xml, server.xml the character encodign parameter <?xml version='1.0' encoding='utf-8'?>.
• Changing URIEncoding to UTF-8 in the connectors. Using firebug, I already see that content-type is set to text/html; utf-8 on the get posts (which are mainly the ones with problems)
• Change meta types and @page on the jsp's to UTF-8.

但我仍然有同样的问题，虽然有些已经解决了，例如，一些重音字母从服务器发送到客户端，正确显示。

But I still have the same problems, although some have been solved, for example, some accented letters sent from the server to the client, are displaying correctly.

我安装了apache2.2和tomcat 6.

I have apache2.2 and tomcat 6 installed.

我不知道还有什么如果你需要一些东西，请告诉我）...

I don't know what else to do nor what relevant information should I post here (if you need something please tell me)...

提前感谢。

推荐答案

确保编码也设置正确的数据库和JDBC驱动程序级别。如何做到这一点取决于DB和JDBC驱动程序make / version。有关详细信息，请参阅DB和JDBC驱动程序特定文档。例如，对于MySQL JDBC驱动程序，您需要向JDBC连接URL添加两个特定的参数。

Make sure that the encoding is also set right at the database and JDBC driver level. How to do that depends on the DB and JDBC driver make/version. Consult the DB and JDBC driver specific documentation for details. For the MySQL JDBC driver for example, you need to add two specific parameters to the JDBC connection URL.

顺便说一下，设置XML文件编码和元标记对HTTP请求/响应编码没有影响。对于基于JSP / Servlet的Web应用程序，只应最小化配置以下内容：

By the way, setting the XML file encoding and the meta tags have no effect on HTTP request/response encoding. Only the following should be minimally configured for a JSP/Servlet based web application:




• 对于HTTP GET请求，水平。在Tomcat中，这可以通过在Tomcat的< Connector> 的 URIEncoding > server.xml

• For HTTP GET requests, configure it at server level. In Tomcat, that's to be done by setting the URIEncoding attribute of <Connector> in Tomcat's server.xml.

对于HTTP POST请求，使用一个 ServletRequest＃setCharacterEncoding （）

For HTTP POST requests, use a filter which does a ServletRequest#setCharacterEncoding().

对于JSP生成的HTTP响应，请设置 pageEncoding 基于每个JSP的属性<％@ page％> ，或者更好地设置< page-encoding>

For HTTP responses generated by JSPs, set pageEncoding attribute of <%@page%> on a per-JSP basis, or, better, set <page-encoding> entry in web.xml for an application-wide basis.

对于HTTP响应，请在 web.xml 由servlet生成（其中不涉及JSP）使用 ServletResponse＃setCharacterEncoding（）。

For HTTP responses generated by servlets (wherein no JSP is been involved!) use ServletResponse#setCharacterEncoding().

最后但同样重要的是，确保您的源代码文件也保存为UTF-8。具体配置取决于所使用的编辑器。在Eclipse的情况下，您可以通过<>>窗口>属性>常规>工作区>文本文件编码来控制它。

Last but not least, make sure that your source code files are also saved as UTF-8. The exact configuration depends on the editor used. In case of Eclipse, you can control it via Window > Properties > General > Workspace > Text File Encoding.
