我用smartupload.getRequest().getRequest()乱码，怎么处理。
request.setCharacterEncoding()不好用。
------解决方案--------------------
你是输出 的JSP 页面乱码？
我使用的是 MYECLIPSE
JSP 头 使用 setchar=UTF-8
然后 MYECLIPSE 设置 JSP HTML 都已 UTF-8 格式打开 重来没有出现过问题。
如果页面是乱码 那么右击IE 的WEB页面 然后选择 字符-》UTF-8
------解决方案--------------------
写一个过滤器 可以用ＵＴＦ－８ 我的过滤器很好用，试试我这个吧
package org.ｐｐｐｐ.filter;
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;
public class SetCharacterEncodingFilter implements Filter {
protected String encoding = null;
protected FilterConfig filterConfig = null;
protected boolean ignore = true;
public void destroy() {
this.encoding = null;
this.filterConfig = null;
}
public void doFilter(ServletRequest request, ServletResponse response,
FilterChain chain)
throws IOException, ServletException {
// Conditionally select and set the character encoding to be used
if (ignore || (request.getCharacterEncoding() == null)) {
String encoding = selectEncoding(request);
if (encoding != null)
request.setCharacterEncoding(encoding);
}
// Pass control on to the next filter
chain.doFilter(request, response);
}
public void init(FilterConfig filterConfig) throws ServletException {
this.filterConfig = filterConfig;
this.encoding = filterConfig.getInitParameter( "encoding ");
String value = filterConfig.getInitParameter( "ignore ");
if (value == null)
this.ignore = true;
else if (value.equalsIgnoreCase( "true "))
this.ignore = true;
else if (value.equalsIgnoreCase( "yes "))
this.ignore = true;
else
this.ignore = false;
}
protected String selectEncoding(ServletRequest request) {
return (this.encoding);
}
}
在web.xml那里配置一下就可以用了.然后页面上统一采用UTF-8编码
------解决方案--------------------
<%@ page language= "java " pageEncoding= "GBK "%>
------解决方案--------------------
<%@ page contentType= "text/html; charset=utf-8 " %>
<meta http-equiv= "Content-Type " content= "text/html; charset=utf-8 ">
