spring boot项目如何使用Filter拦截指定地址

[Tokisaki__Kurumi]

我想在项目里面拦截像www.baidu.com这种链接，应该怎么做呢

@WebFilter(urlPatterns = "/*")
public class UrlFilter implements Filter {
}

    public void doFilter(ServletRequest servletRequest, ServletResponse servletResponse, FilterChain filterChain)
            throws IOException, ServletException {
        String remoteAddr = servletRequest.getRemoteAddr();
        System.out.println("remoteAddr:"+remoteAddr);
        if(remoteAddr.contains("www.baidu.com")){
            // todo
        }
        filterChain.doFilter(servletRequest,servletResponse);
    }
