# tomcat4.X 中的html顯示為亂碼！為什么？
Posted @ 2008-09-09 13:26
-----------------------------------------------------------------------------------------
我的tomcat4.1.29中的加載html文件靜態文件會有亂碼！
而顯示jsp不會有亂碼，請用怎么解決？ 要配置什么tomcat的xml文件嗎?
我現在知道一個解決方法是把index.html文件用記事本打開然后另存為UTF-8格式后就不會亂碼了。可是這只能治標不治本啊！誰有完全解決方法？ 謝謝！
=========================================================================
加入配置:
<mime-mapping>
<extension>htm</extension>
<mime-type>text/html;charset=gb2312</mime-type>
</mime-mapping>
<mime-mapping>
<extension>html</extension>
<mime-type>text/html;charset=gb2312</mime-type>
</mime-mapping>
謝謝,使用以上方法解決了！！！
解決方法是,修改tomcat程序目錄下的 /webapps/web_inf/web.xml 文件,
添加一段配置代碼:
<mime-mapping>
<extension>htm</extension>
<mime-type>text/html;charset=gb2312</mime-type>
</mime-mapping>
<mime-mapping>
<extension>html</extension>
<mime-type>text/html;charset=gb2312</mime-type>
</mime-mapping>
即可解決tomcat中瀏覽html亂碼問題！
如果想解決所有tomcat所有工程亂碼，則應修改 tomcat目錄下 \conf\web.xml 文件即可。
謝謝！！！！
---------------------------------------------------------------
還有一種解決方法是將tomcat和Apache結合一下就行了,讓Apache解釋html,讓tomcat解釋jsp等文件。然后修改只需修改Apache配置就行了。
在Apache的conf文件夾下，httpd.conf，里面有AddDefaultCharset ISO-8859-1，你把它改成 AddDefaultCharset GB2312。
