1、Tomcat和weblogic中文乱码问题解决方案乱码的根本原因是编码和解码的不一致，所以只要把它们置成一样的就可以了。解决乱码最好的方法是增加过滤器。关键代码只有三行：response.setCharacterEncoding(UTF-8);response.setContentType(text/html;charset=UTF-8); request.setCharacterEncoding(UTF-8);使用tomcat服务器可以用一下过滤器先添加一个java类package com;import java.io.IOException;import javax.servlet.Fil

2、ter;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;import javax.servlet.http.HttpServletRequestWrapper;public class TomcatFo

3、rmFilter implements Filter class Request extends HttpServletRequestWrapperpublic Request(HttpServletRequest request) super(request);/* 转换由表单读取的数据的内码.* 从 ISO 字符转到 GBK.*/public String toChi(String input) try /byte bytes = input.getBytes(ISO8859-1);/return new String(bytes, GBK);byte bytes = input.getB

4、ytes(ISO8859-1);return new String(bytes, GBK);catch (Exception ex) return null;/* Return the HttpServletRequest holded by this object.*/private HttpServletRequest getHttpServletRequest()return (HttpServletRequest)super.getRequest();/* 读取参数 - 修正了中文问题.*/public String getParameter(String name)returntoC

5、hi(getHttpServletRequest().getParameter(name);/* 读取参数列表 - 修正了中文问题.*/public String getParameterValues(String name)String values =getHttpServletRequest().getParameterValues(name);if (values != null) for (int i = 0; i values.length; i+) valuesi = toChi(valuesi);return values;public void destroy() publi

6、c void doFilter(ServletRequest request, ServletResponseresponse,FilterChain chain) throws IOException, ServletException HttpServletRequest httpreq = (HttpServletRequest)request;if(httpreq.getMethod().equals(POST) request.setCharacterEncoding(GBK); else request = new Request(httpreq);chain.doFilter(r

7、equest, response);public void init(FilterConfig filterConfig) throwsServletException 再在web.xml中注册这个过滤器，注意红色字体为添加的部分web-app xmlns= xmlns:xsi=http:/www.w3.org/2001/XMLSchema-instance version=2.4 xsi:schemaLocation= action org.apache.struts.action.ActionServlet config /WEB-INF/struts-config.xml debug 3

8、 detail 3 0 TomcatFormFiltercom.TomcatFormFilterTomcatFormFilter/* action *.do weblogic.httpd.inputCharset./*GBK UserSearch/UserSearch.jsp 然而当我们将项目一到weblogic的时候，又有可能出现乱码，那么如何调整过滤器呢？weblogic中的过滤器如下：package com;import java.io.IOException;import javax.servlet.Filter;import javax.servlet.FilterChain;imp

9、ort javax.servlet.FilterConfig;import javax.servlet.ServletException;import javax.servlet.ServletRequest;import javax.servlet.ServletResponse;public class weblogicfilter implements Filter public void init(FilterConfig arg0) throws ServletException public void doFilter(ServletRequest request, Servlet

10、Response response, FilterChain filterChain) throws IOException, ServletException response.setCharacterEncoding(UTF-8); response.setContentType(text/html;charset=UTF-8); request.setCharacterEncoding(UTF-8); filterChain.doFilter(request, response); filterChain.doFilter(request, response); public void

11、destroy() 然后再web.xml中注册过滤器web-app xmlns= xmlns:xsi=http:/www.w3.org/2001/XMLSchema-instanceversion=2.4xsi:schemaLocation= actionorg.apache.struts.action.ActionServletconfig/WEB-INF/struts-config.xmldebug3detail30!- TomcatFormFiltercom.TomcatFormFilter TomcatFormFilter/* -weblogicfiltercom.weblogicfi

12、lteraction*.doweblogic.httpd.inputCharset./*GBKUserSearch/UserSearch.jsp这样的话在weblogic中就不会出现乱码了。这个过滤器理论上在tomcat和weblogic中都适用，但是我试了一下，在weblogic中好用，在tomcat中会乱码，估计是tomcat中编码的问题，可以尝试一下将项目编码该为“utf-8”另外，下面的方法也可以参考一下：1、所有文件的编码格式统一设成UTF-82、tomcat的server.xml文件中有个connector，增加一个属性URIEncoding=utf-83、jsp之间传递参数时，如

13、果包含中文字符，需要用encodeURI(URIString)转换一下这样基本也不会出现乱码的问题。4 配置weblogic.xml pageCheckSeconds 1 compilerSupportsEncoding true encoding GBK / GBK PhoneNumber 过滤器filter1、web.xml PageFilter com.xxxx.PageFilter encoding UTF-8 2、过滤器类import java.io.IOException;import javax.servlet.Filter;import javax.servlet.Filter

14、Chain;import javax.servlet.FilterConfig;import javax.servlet.ServletException;import javax.servlet.ServletRequest;import javax.servlet.ServletResponse;public class PageFilter implements Filter static String encoding = ;public void init(FilterConfig filterConfig) encoding = filterConfig.getInitParameter(encoding);public void doFilter(ServletRequest request, ServletResponse response,FilterChain filterChain) throws IOException, ServletException request.setCharacterEncoding(encoding);filterChain.doFilter(request, response);public void destroy()
