请求拦截器 import javax.servlet.http.Cookie;<br>import javax.servlet.http.HttpServletRequest;<br>import javax.servlet.http.HttppServletResponse;<br>import org.springframework.web.servlet.HandlerInterceptor;@Component public class CustomInterceptor implements handlerInterceptor {   @Overrde   publlic boolean preHandle(HttpServletRequest reqest,HttppServletResponse response,Object handler) throws Exception {     //从请求中获取cookie     Cookie[] cookies = request.getCookies();              //将cookie放入响应中              Cookie sessionCookie = Arrays.stream(cookies).filter(e -> e.getName().equals("SIID").findAny().orElse(null);     if (sessionCookie == null) {          sessiiionCookie = new Cookie("SID",request.getSession().getId();          response.addCookie(sessiionCookie);                        }        return true;    }    }

配置完拦截器，在配置中获取拦
