URL乱码有关问题处理

URL乱码问题处理
首先是过滤器，通过过滤器可以设置所有的post请求

<filter>        <filter-name>struts2</filter-name>        <filter-class>info.frady.filter.FilterDispatcher</filter-class>    </filter>    <filter-mapping>        <filter-name>struts2</filter-name>        <url-pattern>/*</url-pattern>    </filter-mapping>

此代码重写了struct2的过滤器，可以将struct2的过滤器直接用此替换

此过滤器的代码如下

package info.frady.filter;import java.io.IOException;import javax.servlet.FilterChain;import javax.servlet.ServletException;import javax.servlet.ServletRequest;import javax.servlet.ServletResponse;import javax.servlet.http.HttpServletRequest;import org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter;public class FilterDispatcher extends StrutsPrepareAndExecuteFilter {public void doFilter(ServletRequest request, ServletResponse response,FilterChain filterChain) throws IOException, ServletException {request.setCharacterEncoding("UTF-8");HttpServletRequest httpRequest = (HttpServletRequest) request;String url = httpRequest.getRequestURI();super.doFilter(request, response, filterChain);}}

以上处理后，所有的post请求都OK了，那么get请求的链接确实需要传递中文，怎么处理
自己手动加下编码处理下，以下为工具类

package info.frady.util;import java.io.UnsupportedEncodingException;import java.net.URLDecoder;import java.net.URLEncoder;public class UrlUtil {public static final String encode(String s, String encoding) {try {return URLEncoder.encode(s, encoding);} catch (UnsupportedEncodingException e) {return s;}}public static final String dncode(String s, String encoding) {try {return URLDecoder.decode(s, encoding);} catch (UnsupportedEncodingException e) {e.printStackTrace();return s;}}public static final String encodeDefault(String s) {try {return URLEncoder.encode(s, "UTF-8");} catch (UnsupportedEncodingException e) {e.printStackTrace();return s;}}}

在使用的使用，自己拼接url为UrlUtil.encodeDefault(userName)
这样url就被编码成类似这样%E4%B8%AD%E6%96%87

然后，还有然后，需要配置下tomcat

<Connector port="8080" protocol="HTTP/1.1"                connectionTimeout="20000"               redirectPort="8443"  URIEncoding="UTF-8" />

以上所说的仅为utf8，如果你的项目为GBK，请对照修改响应的文件。
