在JSPDeal.jsp文件
的
<%
String name=request.getParameter("Name");
String sex=request.getParameter("Sex");
%>
里面改为：<%
response.setContentType("text/html;charset=GBK")
String name=request.getParameter("Name");
String sex=request.getParameter("Sex");
%>
<%
response.setContentType("text/html;charset=GBK");
%>改为：<%@ page language="java"contentType="text/html; charset=gb2312" pageEncoding="GB2312" import="java.sql.*" errorPage="error.jsp" %>
<%request.setCharacterEncoding("gb2312");%>
String name=request.getParameter("Name");
String sex=request.getParameter("Sex");
%>改为<%
String name=new String(request.getParameter("Name").getBytes("iso-8859-1"),"gbk");
String sex=new String(request.getParameter("Sex").getBytes("iso-8859-1"),"gbk"); %>
2、写过滤器，设置request.setCharacterEncoding("UTF-8")。
3、javascript脚本里用encodeURI(str)。
4、适当的时候，在jsp里用java.net.URLDecoder.decode(request.getParameter("str"),"UTF-8")。
5、最容易忽略的是使用""：value=" <%=paraFiles%>"，一定要有引号。
6、new String(content.getBytes("ISO-8859-1"), "GBK");
我還添加一点就是在JSP头文件设置字符集编码:
<%page@ pageEcoding="UTF-8"%>
个人觉得还是使用过滤器过滤所有请求比较方便!
2
在请求范围要设置编码问题
request.setCharacterEncoding("gbk") ;
响应范围最好也要设置编码问题
response.setCharacterEncoding("gbk"); 3 可以用监听器filter 不过要配置 package filter ;
import javax.servlet.*; public class CharsetFilter implements Filter{
public void destroy() {
}
public void doFilter(ServletRequest request, ServletResponse response,
FilterChain chain) throws IOException, ServletException {
request.setCharacterEncoding("gbk") ;
response.setCharacterEncoding("gbk") ;
chain.doFilter(request, response) ;
}
public void init(FilterConfig config) throws ServletException {
}
}
在web.xml中配置
<filter>
<filter-name>Charset </filter-name>
<filter-class>filter.CharsetFilter </filter-class>
</filter>
<filter-mapping>
<filter-name>Charset </filter-name>
<url-pattern>/* </url-pattern>
</filter-mapping>
