启用zuul
@SpringBootApplication
@EnableZuulProxy
public class DemoApplication {
public static void main(String[] args) {
SpringApplication.run(DemoApplication.class, args);
}
}
application.yaml
zuul:
routes:
demo:
path: /demo/**
url: forward:/demo
product:
path: /product/**
stripPrefix: false
product:
ribbon:
listOfServers: 192.168.99.100:8080
ribbon:
eureka:
enabled: false
其中,使用listOfServers可以配置外部服务的多个负载均衡;使用forward可以forward到外部地址,也可以forward内部的相对地址。
配置filter
@Component
public class DemoFilter extends ZuulFilter {
private static final Logger LOGGER = LoggerFactory.getLogger(DemoFilter.class);
@Override
public String filterType() {
return "pre";
}
@Override
public int filterOrder() {
return 0;
}
@Override
public boolean shouldFilter() {
return true;
}
@Override
public Object run() {
RequestContext ctx = RequestContext.getCurrentContext();
HttpServletRequest request = ctx.getRequest();
String token = request.getHeader("token");
if(StringUtils.isEmpty(token)){
requestContext.setResponseStatusCode(HttpStatus.UNAUTHORIZED.value());
requestContext.setSendZuulResponse(false);
throw new RuntimeException("UNAUTHORIZED");
}
return null;
}
}
