apache+tomcat 整合url参数乱码

解决apache+tomcat下的URL中文乱码问题的方法：
1）tomcat下的conf/server.xml
两处加上URIEncoding="UTF-8"

如下：

  <Connector
port="8080"               maxHttpHeaderSize="8192"
               maxThreads="150" minSpareThreads="25" maxSpareThreads="75"
               enableLookups="false" redirectPort="8443" acceptCount="100"
               connectionTimeout="20000" disableUploadTimeout="true" URIEncoding="UTF-8"/>

另一处：这一处很关键，因为如果与apache结合时，端口转发时也要编码成UTF-8

    <Connector port="8009"
               enableLookups="false" redirectPort="8443" protocol="AJP/1.3" URIEncoding="UTF-8" />

2）在URLEncoder.encode中指明用UTF-8编码。

<a href=tag.jsp?tag=<%=URLEncoder.encode(blog.getTags(),"UTF-8")%>><strong><font color=red><%=blog.getTags() %>
解码时直接用
java.net.URLDecoder.decode(request.getParameter("tag"));即可解决乱码问题！
