在Spring Cloud Gateway中,可以通过配置文件或编程方式设置每条路由的超时时间。
metadata
属性来设置超时时间,单位为毫秒。GatewayFilterFactory
接口的自定义过滤器类,例如TimeoutGatewayFilterFactory
:import org.springframework.cloud.gateway.filter.GatewayFilter;
import org.springframework.cloud.gateway.filter.factory.GatewayFilterFactory;
import org.springframework.stereotype.Component;import java.util.Arrays;
import java.util.List;
@Component
public class TimeoutGatewayFilterFactory implements GatewayFilterFactory<TimeoutGatewayFilterFactory.Config> {
@Override
public GatewayFilter apply(Config config) {
return (exchange, chain) -> {
// 设置超时时间
exchange.getAttributes().put("timeout", config.getTimeout());
return chain.filter(exchange);
};
}
@Override
public List<String> shortcutFieldOrder() {
return Arrays.asList("timeout");
}
@Override
public Class<Config> getConfigClass() {
return Config.class;
}
public static class Config {
private int timeout;
public int getTimeout() {
return timeout;
}
public void setTimeout(int timeout) {
this.timeout = timeout;
}
}
}
然后,在路由配置中使用该自定义过滤器:
@Configuration
public class GatewayConfig {
@Bean
public RouteLocator customRouteLocator(RouteLocatorBuilder builder) {
return builder.routes()
.route("route1", r -> r.path("/example/**")
.filters(f -> f.filter(new TimeoutGatewayFilterFactory().apply(new TimeoutGatewayFilterFactory.Config(5000))))
.uri("http://example.com"))
.route("route2", r -> r.path("/example2/**")
.filters(f -> f.filter(new TimeoutGatewayFilterFactory().apply(new TimeoutGatewayFilterFactory.Config(10000))))
.uri("http://example2.com"))
.build();
}
}
在上述代码中,通过TimeoutGatewayFilterFactory.Config
类来设置超时时间,单位为毫秒。
无论是通过配置文件还是编程方式设置超时时间,都可以根据具体需求来灵活配置每条路由的超时时间。
