在数据库连接时添加：Connection Conn=DriverManager.getConnection("jdbc:mysql://localhost /test?useUnicode=true&characterEncoding=gb2312（或utf-8）","root","");

将mysql中的filed charset 属性设置为gbk.

添加类SetEncodingFilter

import javax.servlet.Filter;
import javax.servlet.FilterConfig;
import javax.servlet.ServletException;
import javax.servlet.ServletRequest;
import javax.servlet.ServletResponse;
import javax.servlet.FilterChain;
import java.io.IOException;

/** *//**
* 请求中中文字符串过滤类
*/

public class SetEncodingFilter
implements Filter{

public void init(FilterConfig filterConfig) throws ServletException {
}

public void doFilter(ServletRequest request, ServletResponse response,
FilterChain chain) throws IOException, ServletException {

request.setCharacterEncoding("gb2312");
chain.doFilter(request,response);
}

public void destroy(){
}
}
