网关_zuul_Route三种过滤器使用方式
作者:互联网
1、网关通过url到服务
1 @Override 2 public Object run() throws ZuulException { 3 RequestContext currentContext = RequestContext.getCurrentContext(); 4 HttpServletRequest request = currentContext.getRequest(); 5 //获取访问地址 6 String remoteAddr = request.getRequestURI(); 7 8 //和老地址做匹配 9 if(remoteAddr.contains("/send/sms-test31")){ 10 //服务具体路径 11 currentContext.set(FilterConstants.REQUEST_URI_KEY,"/send/sms-test3"); 12 //服务实例 13 currentContext.set(FilterConstants.SERVICE_ID_KEY,"service-sms"); 14 } 15 16 17 return null; 18 }
2、网关访问具体url服务
访问指定url跳转具体的后端服务
@Override public Object run() throws ZuulException { RequestContext currentContext = RequestContext.getCurrentContext(); HttpServletRequest request = currentContext.getRequest(); //获取访问地址 String remoteAddr = request.getRequestURI(); //和老地址做匹配 if(remoteAddr.contains("/zuul-test")){ currentContext.set(FilterConstants.SERVICE_ID_KEY,"service-sms"); try{ currentContext.setRouteHost(new URI("http://localhost:8003/send/sms-test3").toURL()); }catch (Exception e){ } } return null; }
3、网关的自我转发
yml:
zuul: routes: aaa: path: /forward1/** url: forward:/myyml
java:
访问:http://localhost:9100/forward1,完成自我转发
@RequestMapping(value = "/myyml") public String test(){ return "myyml"; }
