在RedHat里安装tomcat5写入数据库的汉字是乱码怎么回事

[wangzg30]

在RedHat里安装tomcat5写入数据库的汉字是乱码怎么回事，已经设置了request.setCharacterEncoding("GB2312");还是不行，请高手帮忙。

tomcat5默认是使用Iso8891的字符集的, 你搞个设置CharacterEncoding的Filter吧, 并在Web.xml配置一下

package util;

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 SetEncodeFilter implements Filter {

protected FilterConfig filterConfig = null;

protected String defaultEncoding = null;

/* (non-Javadoc)
* @see javax.servlet.Filter#init(javax.servlet.FilterConfig)
*/
public void init(FilterConfig arg0) throws ServletException {
// TODO Auto-generated method stub
this.filterConfig = arg0;
this.defaultEncoding = filterConfig.getInitParameter("defaultencoding");
}

/* (non-Javadoc)
* @see javax.servlet.Filter#doFilter(javax.servlet.ServletRequest, javax.servlet.ServletResponse, javax.servlet.FilterChain)
*/
public void doFilter(
ServletRequest request,
ServletResponse response,
FilterChain chain)
throws IOException, ServletException {
// TODO Auto-generated method stub
request.setCharacterEncoding(selectEncoding(request));
chain.doFilter(request, response);
}

public void destroy() {
// TODO Auto-generated method stub
this.defaultEncoding = null;
this.filterConfig = null;
}


protected String selectEncoding(ServletRequest request) {

return this.defaultEncoding;
}

}
