[英]How to use UTF-8 with tomcat
Tomcat does not encode correctly String literals that contain unicode characters. Tomcat无法正确编码包含unicode字符的字符串文字。 The problem occurs at a Linux server but not on my development machine (Windows). 问题发生在Linux服务器上,但不在我的开发机器上(Windows)。 It affects ONLY String literals (not Strings read from DB or from file!!!). 它仅影响字符串文字(不是从DB或文件中读取的字符串!!!)。
URIEncoding="utf-8"
at the Connector tag (server.xml). 我在Connector标签(server.xml)上设置了URIEncoding="utf-8"
。 Nothing of the above works. 上述任何内容都无效。 Any ideas on what I might be missing? 关于我可能遗失的任何想法?
public class Test extends HttpServlet {
@Override
protected void doGet(HttpServletRequest req, HttpServletResponse resp) throws ServletException, IOException {
resp.setCharacterEncoding("utf-8");
resp.setContentType("text/plain;");
Writer w = resp.getWriter();
w.write("Μαλακία Latin"); //Some unicode characters
w.close();
}
The above shows this at the browser. 以上内容在浏览器中显示。 Îλληνικά Latin ÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎ
You can force the encoding of files when javac reads them by passing in -encoding 'utf-8' or -encoding 'iso-8859-1' when compiling. 当javac通过在编译时传入-encoding'utf-8'或-encoding'iso-8859-1'来强制读取文件时,可以强制进行文件编码。 Just make sure that it matches whatever encoding your .java files are actually encoded as. 只需确保它匹配您的.java文件实际编码为的任何编码。

-encoding encoding Set the source file encoding name, such as EUC-JP and UTF-8. -encoding encoding设置源文件编码名称,例如EUC-JP和UTF-8。 If -encoding is not specified, the platform default converter is used. 如果未指定-encoding,则使用平台默认转换器。
尝试在Linux JVM命令行上设置file.encoding系统属性,例如-Dfile.encoding=utf-8
