J2EE开发中，网址链接中存在中文如何正常显示。
在web.xml中增加过滤器 <filter> <filter-name>urlFilter</filter-name> <filter-class>com.dj.filter.UrlFilter</filter-class> <init-param> <param-name>DEFAULT_URI_ENCODE</param-name> <param-value>UTF-8</param-value> </init-param> </filter> <filter-mapping> <filter-name>urlFilter</filter-name> <url-pattern>/*</url-pattern> </filter-mapping> 在src中增加过滤器代码 package com.dj.filter; import java.io.IOException; import java.net.URLDecoder; import javax.servlet.Filter; import javax.servlet.FilterChain; import javax.servlet.FilterConfig; import javax.servlet.ServletException; import javax.servlet.ServletRequest; import javax.servlet.ServletResponse; import javax.servlet.http.HttpServletRequest; public class UrlFilter implements Filter { public final static String DEFAULT_URI_ENCODE = "UTF-8"; private FilterConfig config = null; private String encode = null; public void init(FilterConfig config) throws ServletException { this.config = config; this.encode = config.getInitParameter("DEFAULT_URI_ENCODE"); if(this.encode == null) { this.encode = DEFAULT_URI_ENCODE; } } public void doFilter(ServletRequest req, ServletResponse res, FilterChain chain) throws IOException, ServletException { HttpServletRequest request = (HttpServletRequest) req; String uri = request.getRequestURI(); String ch = URLDecoder.decode(uri, encode); if(uri.equals(ch)) { chain.doFilter(req, res); return; } ch = ch.substring(request.getContextPath().length()); config.getServletContext().getRequestDispatcher(ch).forward(req, res); } public void destroy() { config = null; } }
