Spring cloud Gateway specify the execution filter (arranged in the filter configuration file required)

                                   Spring cloud Gateway designated to perform the filter 

                                               Configuration needed in the filter configuration file

 

gateway configuration is divided into two filter

①: global filters

Global Filters do not need to profile configuration, all requests to the service will intercept,

/**
 * @author 荡漾
 * @title: TokenFilter
 * @projectName gateway
 * @description: TODO token校验全局过滤器
 * @date 2019/6/21  12:41
 */
@Configuration
@Slf4j
public class TokenFilter implements GlobalFilter, Ordered {

    @Override
    public int getOrder() {
        return -10000;
    }

 @Override
    public Mono<Void> filter(ServerWebExchange exchange, GatewayFilterChain chain) {
       return chain.filter(exchange);
  }
}

②: Specifies the filter

Need to inherit AbstractGatewayFilterFactory  

Advantages, can be configured in the configuration file, the filter can be specified for a service,

Simply filter corresponding to the name of the configuration file as shown:

It is worth noting that if you filter name suffix is ​​GatewayFilterFactory as TestGatewayFilterFactory just write Test in configuration files if you can not then write the full name on it

@Component
@Slf4j
public class Test  extends AbstractGatewayFilterFactory<Test.NameConfig> {


    public Test() {
        super(NameConfig.class);
        log.info("Loaded GatewayFilterFactory [Authorize]");
    }

    @Override
    public GatewayFilter apply(Test.NameConfig config) {
        return (exchange, chain) -> {
            System.out.println("=  =  =  =  =  = 执行了=  =  =  =  =  =  =  =");
            return chain.filter(exchange);
        };
    }
    public static class NameConfig {

        private String name;

        public String getName() {
            return name;
        }

        public void setName(String name) {
            this.name = name;
        }

    }
}
