Tomcat--怎样到处使用UTF-8编码

原文地址：https://wiki.apache.org/tomcat/FAQ/CharacterEncoding#Q3

Using UTF-8 as your character encoding for everything is a safe bet. This should work for pretty much every situation.

In order to completely switch to using UTF-8, you need to make the following changes:

1. Set URIEncoding="UTF-8" on your <Connector> in server.xml. References: HTTP Connector, AJP Connector.

2. Use a character encoding filter with the default encoding set to UTF-8

3. 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).

4. 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") or response.setCharacterEncoding("UTF-8").

5. 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.

6. 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/[e-mail]/msg21117.html.
