一般表单提交有POST,GET方式，不过处理的时候方法有所区别一般post可以在JSP页面添加<% request.setCharacterEncoding="GBK";%> 来处理GET方式可以用转换编码方式类似的如：<%String username = new String(username.getBytes("ISO8859_1"),"GBK");%>不过这不是很好的处理方式，比较麻烦。每个页面都要写这样重复的转换。POST方式一般可以用Filter过滤的Servlet来实现创建EncodingFilter.java=======================/* * CoppyRight (c) Eays Studio * description:LoginAction */package net.eays.servlet;
import java.io.IOException;import java.io.PrintWriter;import javax.servlet.Filter;import javax.servlet.FilterChain;import javax.servlet.FilterConfig;import javax.servlet.ServletException;import javax.servlet.http.HttpServlet;import javax.servlet.http.HttpServletRequest;import javax.servlet.http.HttpServletResponse;import javax.servlet.ServletRequest;import javax.servlet.ServletResponse;import javax.servlet.ServletException;/** * @author 小林信仁 * Creation date: 05-09-2007 */public class EncodingFilter implements Filter {
/** * Constructor of the object. */ private FilterConfig config = null; private String targetEncoding = "GBK"; public EncodingFilter() { super(); }
/** * Destruction of the servlet. <br> */ public void destroy() { config = null; targetEncoding = null; }
/** * Initialization of the servlet. <br> * * @throws ServletException if an error occure */ public void init(FilterConfig config) throws ServletException { this.config = config; this.targetEncoding = config.getInitParameter("encoding"); System.out.println("init get value:"+ this.targetEncoding ); } public void doFilter(ServletRequest request,ServletResponse response,FilterChain chain) throws IOException,ServletException{ System.out.println("targetEncoding :" + targetEncoding + "/n"); request.setCharacterEncoding(targetEncoding); chain.doFilter(request, response); }
}
==============================Web.xml中EncodingFilter过滤器配置添加========================<filter> <description>EncodingFilter</description> <display-name>EncodingFilter</display-name> <filter-name>EncodingFilter</filter-name> <filter-class>net.eays.servlet.EncodingFilter</filter-class> <init-param> <description>encoding to GB2312</description> <param-name>encoding</param-name> <param-value>GB2312</param-value> </init-param> </filter> <filter-mapping> <filter-name>EncodingFilter</filter-name> <url-pattern>/*</url-pattern> </filter-mapping>=============================处理Get方式以上还是不行，Tomcat可以修改server.xml文件============================知道 <Connector最后添加属性 useBodyEncodingForURI="true"============================OK,一切的乱码问题通通解决！
