Question

是JSP吗？
在传输过程中加一个过滤器Filter
把内容转换成UTF就可以了

Answer 1

页面什么编码a
filter  a->utf-8

Answer 2

public class EncodingFilter extends HttpServlet implements Filter { String encoding; ServletContext context; private static final String DEFAULT_CHARACTER_ENCODING = "gb2312"; public void init(FilterConfig arg0) throws ServletException {
// TODO 自动生成方法存根
context = arg0.getServletContext();
encoding = arg0.getInitParameter("encoding");
// System.out.println("init........");
} public void doFilter(ServletRequest arg0, ServletResponse arg1,
FilterChain arg2) throws IOException, ServletException {
// TODO 自动生成方法存根
try {
if (encoding != null && encoding.length() > 0) {
arg0.setCharacterEncoding(encoding);
// System.out.println("in filter encoding=" + encoding);
context.log("in filter.encoding=" + encoding); } else {
arg0.setCharacterEncoding(DEFAULT_CHARACTER_ENCODING);
}
} catch (UnsupportedEncodingException e) {
// TODO 自动生成 catch 块
arg0.setCharacterEncoding(DEFAULT_CHARACTER_ENCODING);
e.printStackTrace();
}
arg2.doFilter(arg0, arg1);

} // public void destroy() {
// // TODO 自动生成方法存根
//
// }}

Answer 3

加个过滤器简单点
要么就在jsp页面用中文编码 像GBK，然后在后后台的源码中设置request为中文编码，再插入库中

Answer 4

过滤器代码如下：以前写的，
import javax.servlet.ServletResponse;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;public class EncodingFilter implements Filter { public void destroy() { } public void doFilter(ServletRequest request, ServletResponse response,
FilterChain chain) throws IOException, ServletException {

request.setCharacterEncoding("GBK");
HttpServletRequest httpRequest = (HttpServletRequest)request;
HttpServletResponse httpResponse = (HttpServletResponse)response;
String url= httpRequest.getRequestURI();
Object object = httpRequest.getSession().getAttribute("userSession");
if(object!=null || url.endsWith("login.jsp") || url.startsWith(httpRequest.getContextPath()+"/LoginServlet") 
|| url.startsWith(httpRequest.getContextPath()+"/css")){
chain.doFilter(request, response);
}else{
httpResponse.sendRedirect(httpRequest.getContextPath()+"/login.jsp");
}


} public void init(FilterConfig arg0) throws ServletException { }}web.xml配置如下：
 <filter>
<filter-name>EncodingFilter</filter-name>
<filter-class>com.s10.rg.util.EncodingFilter</filter-class>  
  </filter>   <filter-mapping>
   <filter-name>EncodingFilter</filter-name>
   <url-pattern>/*</url-pattern>
  </filter-mapping>
