ITomcat和weblogic中文乱码问题解决方案.docxVIP

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.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;import javax.servlet.http.HttpServletRequestWrapper;public class TomcatFormFilter implements Filter {class Request extends HttpServletRequestWrapper{public 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.getBytes(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){returntoChi(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++) {values[i] = toChi(values[i]);}}return values;}}public void destroy() {}public 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(request, 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?xml version=1.0 encoding=
