本文详细介绍了如何将Tomcat环境彻底切换至UTF-8编码的步骤，包括配置HTTP/AJP连接器、使用字符编码过滤器、修改JSP页面、设置Servlet响应类型及内容类型、调整内容生成库、禁用可能读取请求参数的阀门或过滤器等关键操作。

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:

Set URIEncoding="UTF-8" on your <Connector> 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") or response.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.
