我用jdbc连接sql server2005中文出现乱码

Question

我写了个类，然后再web.xml配置了一下
package helper;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;
import javax.servlet.http.HttpServletRequest;public class UTF8Filter implements Filter { public void destroy() {

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

((HttpServletRequest)request).setCharacterEncoding("utf-8");
((HttpServletRequest)request).setCharacterEncoding("utf-8");
       chain.doFilter(request, response);
System.out.println("hhhhhh");
} public void init(FilterConfig arg0) throws ServletException {

}

}
下边的是我的配置
<filter>
<filter-name>UTF8Filter</filter-name>
<filter-class>helper.UTF8Filter</filter-class>
</filter>
<filter-mapping>
<filter-name>UTF8Filter</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>JDBCSQL ServerUTF-8Filter
