从JAVA类到JSP的乱码解决问题

Question

楼主用什么方法把参数传到页面的呢？加JSP页面里加一句这个呢：
request.setCharencoding="gb2312“

Answer 1

struts.xml里面加
<constant name="struts.i18n.encoding" value="GBK" />struts2 中最好统一用utf-8
页面统一用UTF-8
看看你的 WEB.XML中这里的设置
<init-param>
<param-name>encoding</param-name>
<param-value>UTF-8</param-value>
</init-param>

Answer 2

上面方法不行
可以在试试这个在 action中加
HttpServletResponse response = null;  
HttpServletRequest request=null;
response = ServletActionContext.getResponse();    
request.setCharacterEncoding("utf-8");     
response.setContentType("text/html;charset=utf-8");

Answer 3

写个过滤器吧，有的时候直接转换是不行的，得写个过滤器。呵呵
code
package com.web.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 EncodingFilter implements Filter {
protected String encoding = null; protected FilterConfig filterConfig = null; public void doFilter(ServletRequest request, ServletResponse response,
FilterChain chain) throws IOException, ServletException {
String encoding = selectEncoding(request);
if (encoding != null) {
request.setCharacterEncoding(encoding);
}
chain.doFilter(request, response);
}
public void init(FilterConfig filterConfig) throws ServletException {
this.filterConfig = filterConfig;
this.encoding = filterConfig.getInitParameter("encoding");
System.out.println("ok");
}
public void destroy() {
this.encoding = null;
this.filterConfig = null;
}
protected String selectEncoding(ServletRequest request) {
return (this.encoding);
}}
这个是web. xml中的配置文件，直接考上去就可以用了
          <filter>
<filter-name>Encoding</filter-name>
<filter-class>com.web.filter.EncodingFilter</filter-class>
<init-param>
<param-name>encoding</param-name>
<param-value>GBK</param-value>
</init-param>
</filter>
<filter-mapping>
<filter-name>Encoding</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>
记得结贴哦，呵呵！

Answer 4

用这个最省心~~
String src = new String(src.getBytes("ISO8859_1"),"GBK");当然,最好整合spring;
<filter>
  <filter-name>Spring character encoding filter</filter-name> 
  <filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class> 
<init-param>
  <param-name>encoding</param-name> 
  <param-value>GBK</param-value> 
</init-param>
</filter>
顺便问句,struts2是把值存在map里,然后再jsp用el或者struts2标签取,怎么可能乱码;
Map voPut= ActionContext.getContext().getSession();
voPut.put("user", this);

Answer 5

request.setCharacterEncoding(GBK); 
  
response.setContentType(text/html; charset=GBK);

Answer 6

把发送的参数编一下码，比如做一下加密处理，在页面上再解密，Base64即可解决
