总结解决JSP开发Web程序中文显示三种方法方法一：最简单也是用的最多的方法 % page language="javapageEncoding="GBK%或者% page contenttype="text/html;charset=gbk"这里可以用gb2312或者gbk，只是gbk比gb2312支持跟多的字符。这个方法用于jsp页面中的中文显示。方法二：使用过滤器过滤器使用主要针对表单提交，插入数据库的数据都是？号。这也是应为tomcat不按request所指定的编码进行编码，还是自作主张的采用默认编码方式iso-8859-1编码。编写一个SetCharacterEncodingFilter类。importjava.io.IOException;importjavax.servlet.Filter;importjavax.servlet.FilterChain;importjavax.servlet.FilterConfig;importjavax.servlet.ServletException;importjavax.servlet.ServletRequest;importjavax.servlet.ServletResponse;publicclassSetCharacterEncodingFilterimplementsFilterprotectedStringencoding=null;protectedFilterConfigfilterConfig=null;protectedbooleanignore=true;publicvoidinit(FilterConfigfilterConfig)throwsServletExceptionthis.filterConfig=filterConfig;this.encoding=filterConfig.getInitParameter("encoding");Stringvalue=filterConfig.getInitParameter("ignore");if(value=null)this.ignore=true;elseif(value.equalsIgnoreCase("true")this.ignore=true;elsethis.ignore=false;publicvoiddoFilter(ServletRequestrequest,ServletResponseresponse,FilterChainchain)throwsIOException,ServletException/TODO自动生成方法存根if(ignore (request.getCharacterEncoding()=null)Stringencoding=selectEncoding(request);if(encoding!=null)request.setCharacterEncoding(encoding);chain.doFilter(request,response);publicvoiddestroy()/TODO自动生成方法存根this.encoding=null;this.filterConfig=null;protectedStringselectEncoding(ServletRequestrequest)return(this.encoding);然后再web.xml加上!-SetCharacterEncoding-filterfilter-nameSetCharacterEncoding/filter-namefilter-classmon.SetCharacterEncodingFilter/filter-classinit-paramparam-nameencoding/param-nameparam-valueUTF-8/param-value/init-param/filterfilter-mappingfilter-nameSetCharacterEncoding/filter-nameurl-pattern/*/url-pattern/filter-mapping!-SetCharacterEncoding-使用过滤器的好处很多，特别是项目之中。而且在使用国际化时就更有用了，只要在页面指定 % page language="javapageEncoding="UTF-8%，服务器就会根据本地Locale来显示正确的字符集。所以我特别推荐使用过滤器。方法三：修改tomcat的server.xml文件中URIEncodingConnectordebug="0"acceptCount="100"connectionTimeout="20000"disableUploadTimeout="true"port="80"redirectPort="8443"enableLookups="false"minSpareThreads="25"maxSpareThreads="75"maxThreads="150"maxPostSize="0"URIEncoding="GBK"/Connector这个方法主要针对从url中获取字符串的问题。在tomcat5.
