hbuilderx里面的登录功能怎么从MySQL获取数据

可以在myeclipse里面搭建一个自己的过滤器，代码如下：
//过滤器
public class crossDomainFilter implements Filter{undefined

public void destroy() {undefined}
public void doFilter(ServletRequest req, ServletResponse resp, FilterChain chain)

throws IOException, ServletException {undefined

HttpServletResponse res = (HttpServletResponse) resp;
