1.新建一个filter‘包

2.新建一个类，实现ZuulFilter，重写里面的方法

3.在顶部类添加注解，@Component，让Spring扫描

/** * 登陆过滤器 */@Componentpublic class LoginFilter extends ZuulFilter { @Override public String filterType() { //前置过滤器 return PRE_TYPE; } @Override public int filterOrder() { //过滤器顺序，越小越先执行 return 3; } @Override public boolean shouldFilter() { //过滤器是否生效 RequestContext requestContext = RequestContext.getCurrentContext(); HttpServletRequest request = requestContext.getRequest(); System.out.println(request.getRequestURI()); System.out.println(request.getRequestURL()); if ("/apizuul/order/api/v1/order/save".equalsIgnoreCase(request.getRequestURI())){ //拦截 return true; } return false; } /** * 业务逻辑 * @return * @throws ZuulException */ @Override public Object run() throws ZuulException { System.out.println("拦截..."); RequestContext requestContext = RequestContext.getCurrentContext(); HttpServletRequest request = requestContext.getRequest(); String token = request.getHeader("token"); if (StringUtils.isBlank(token)){ token = request.getParameter("token"); } //登陆校验逻辑 jwt生成token if (StringUtils.isBlank(token)){ requestContext.setSendZuulResponse(false); //不会往下执行 requestContext.setResponseStatusCode(HttpStatus.UNAUTHORIZED.value()); } return null; }
