struts 关于从数据库读出数据,页面汉字乱码

Question

在server.xml文件找到<Connector .../>，然后加上<Connector ... URIEncoding="GBK"/>
,你试一试吧！

Answer 1

我自己测试没问题的..给个例子你试一下!
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 {
      
        if (ignore || (request.getCharacterEncoding() == null)) {
            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");
        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);    }
}
web.xml中配置一下..就OK了..不需要在 Action中在设置编码了
 <filter>   <filter-name>setCharsEncoding</filter-name>
  <filter-class>SetCharacterEncodingFilter</filter-class>
  <init-param>
     <param-name>encoding</param-name>
     <param-value>gb2312</param-value>
   </init-param>
 </filter>

哦忘了贴了  过滤/*就可以了   <filter-mapping>
   <filter-name>setCharsEncoding</filter-name>
   <url-pattern>/*</url-pattern>
  </filter-mapping>
