					# -----------------------------------------------------------------------------------------tomcat4.X 中的html显示为乱码!为什么?  
				Posted @ 2008-09-09 13:26
				 
 我的tomcat4.1.29中的加载html文件静态文件会有乱码!
 而显示jsp不会有乱码,请用怎么解决?    要配置什么tomcat的xml文件吗?
 
 我现在知道一个解决方法是把index.html文件用记事本打开然后另存为UTF-8格式后就不会乱码了。可是这只能治标不治本啊!谁有完全解决方法?  谢谢!
 =========================================================================
 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>
 
 谢谢,使用以上方法解决了!!!
 
 解决方法是,修改tomcat程序目录下的  /webapps/web_inf/web.xml  文件,
 
 添加一段配置代码:
 
 <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>
 
 即可解决tomcat中浏览html乱码问题!
 
 如果想解决所有tomcat所有工程乱码,则应修改  tomcat目录下  \conf\web.xml  文件即可。
 
 谢谢!!!!
 
 
 ---------------------------------------------------------------
 还有一种解决方法是将tomcat和Apache结合一下就行了,让Apache解释html,让tomcat解释jsp等文件。然后修改只需修改Apache配置就行了。
 在Apache的conf文件夹下,httpd.conf,里面有AddDefaultCharset  ISO-8859-1,你把它改成  AddDefaultCharset  GB2312。
