创建项目

  • 使用Spring Initializr创建项目，依赖选择Gateway、Resilience4J、Contract Stub Runner

创建简单路由

  • Spring Cloud Gateway使用路由（routes）来处理服务请求，本文档中使用HTTPBin作为请求目标，所有请求都被路由到HTTPBin。
  • 可以使用多种方式配置路由，本文档使用网关提供的Java API
  • 在src/test/java/com/example/springcloudgatewayofficialdemo/SpringCloudGatewayOfficialDemoApplicationTests.java创建一个RouteLocator类型的Bean
package com.example.springcloudgatewayofficialdemo;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.cloud.gateway.route.RouteLocator;
import org.springframework.cloud.gateway.route.builder.RouteLocatorBuilder;
import org.springframework.context.annotation.Bean;

/**
 * @author histonevon
 */
@SpringBootApplication
public class SpringCloudGatewayOfficialDemoApplication {

    public static void main(String[] args) {
        SpringApplication.run(SpringCloudGatewayOfficialDemoApplication.class, args);
    }

    @Bean
    public RouteLocator myRoutes(RouteLocatorBuilder builder) {
        return builder.routes().build();
    }

}
  • myRoutes方法采用可创建路由的RouteLocatorBuilder，它也允许我们添加谓词（predicates）和过滤器（filters），这样我们就可以根据特定条件路由句柄根据需要更改请求与响应
  • 创建路由：当向网关发送请求/get时，该路由将请求到http://httpbin.org/get（非https），在此路由的配置中，添加一个过滤器（filters），在路由请求之前将"Hello": "World"添加到请求头
    @Bean
    public RouteLocator myRoutes(RouteLocatorBuilder builder) {
        // return builder.routes().build();
        return builder.routes()
                .route(p -> p
                        .path("/get") // 请求路径
                        .filters(f -> f.addRequestHeader("Hello", "World")) // 拦截器
                        .uri("http://httpbin.org:80") // 统一资源定位符（Uniform Resource Identifier）
                ).build();
    }
  • 在8080端口运行项目，向http://localhost:8080/get发送请求，我这里使用开源的Httpie Desktop发送请求，响应如下

image-20230718133753525

{
  "args": {},
  "headers": {
    "Accept": "*/*",
    "Content-Length": "0",
    "Forwarded": "proto=http;host=\"localhost:8080\";for=\"[0:0:0:0:0:0:0:1]:60612\"",
    "Hello": "World",
    "Host": "httpbin.org",
    "User-Agent": "HTTPie",
    "X-Amzn-Trace-Id": "Root=1-64b624ca-31c2fc67027c89542b850b66",
    "X-Forwarded-Host": "localhost:8080"
  },
  "origin": "0:0:0:0:0:0:0:1, 112.96.226.72",
  "url": "http://localhost:8080/get"
}
  • 注意：值为World的请求标头Hello已经在headers中发送
  • 如果使用https://localhost:8080/get则会出现以下问题

使用CircuitBreaker

  • 通过Resilience4J使用，CircuitBreaker是Resilience4J的组件

  • Resilience4J是一个断路器，其**是如果我们知道调用可能会失败或超时，则阻止对远程服务的调用。这是为了我们的远程服务不必浪费关键资源，这样的退出也给了远程服务一些时间来恢复。

  • 通过跟踪对远程服务发出的先前请求的结果，我们就会知道一个调用是否会失败 。例如，如果前10次调用中有8次导致失败或超时，则下一次调用也很可能会失败。

  • 断路器通过包装对远程服务的调用来跟踪响应

    • 在正常运行期间，当远程服务成功响应时，我们说断路器处于“闭合”状态，断路器正常将请求传递给远程服务。
    • 当远程服务返回错误或超时时，断路器会增加一个内部计数器。如果错误计数超过配置的阈值，断路器将切换到“断开”状态，断路器立即向调用者返回错误，甚至无需尝试远程调用。
    • 经过一段配置的时间后，断路器从断开状态切换到“半开”状态。在这种状态下，它允许一些请求传递到远程服务以检查它是否仍然不可用或缓慢。 如果错误率或慢呼叫率高于配置的阈值，则切换回断开状态。但是，如果错误率或慢呼叫率低于配置的阈值，则切换到关闭状态以恢复正常操作。

  • 使用HTTPBin的延迟API，它在发送响应之前等待一定的秒数。由于此API可能需要很长时间才能发送其响应，因此我们可以将使用此API的路由包装在断路器中

  • 按照官网Guide，添加依赖，否则不行（我看漏了，浪费了一些时间）

<dependency>
    <groupId>org.springframework.cloud</groupId>
    <artifactId>spring-cloud-starter-circuitbreaker-reactor-resilience4j</artifactId>
</dependency>
  • 按照官网Guide，添加路由
@SpringBootApplication
public class SpringCloudGatewayOfficialDemoApplication {

    public static void main(String[] args) {
        SpringApplication.run(SpringCloudGatewayOfficialDemoApplication.class, args);
    }

    @Bean
    public RouteLocator myRoutes(RouteLocatorBuilder builder) {
        // return builder.routes().build();
        return builder.routes()
                .route(p -> p
                        .path("/get") // 请求路径
                        .filters(f -> f.addRequestHeader("Hello", "World")) // 拦截器
                        .uri("http://httpbin.org:80")) // 统一资源定位符（Uniform Resource Identifier）
                .route(p -> p
                        .host("*.circuitbreaker.com") //只要主机是 *.circuitbreaker.com ，就将请求路由到httpbin
                        .filters(f -> f.circuitBreaker(config -> config.setName("mycmd"))) // 使用配置对象设置circuitBreaker，此处设置名称
                        .uri("http://httpbin.org:80"))
                .build();
    }

}
  • 请求地址：http://localhost:8080/delay/3，注意在请求头中修改Host为www.circuitbreaker.com
  • 请求结果如下，出现504 Gateway Timeout，即断路器在等待来自 HTTPBin 的响应时超时

![image-20230718165239580](./Spring Cloud Gateway学习及Demo项目.assets/image-20230718165239580.png)

  • 当断路器超时，可以选择回退（fallback），以便客户端不会收到更有意义的东西。例如，在生产方案中，缓存中返回一些数据，本文档中返回带有正文的响应
  • 设置超时使用的url
@Bean
public RouteLocator myRoutes(RouteLocatorBuilder builder) {
    // return builder.routes().build();
    return builder.routes()
        .route(p -> p
               .path("/get") // 请求路径
               .filters(f -> f.addRequestHeader("Hello", "World")) // 拦截器
               .uri("http://httpbin.org:80")) // 统一资源定位符（Uniform Resource Identifier）
        .route(p -> p
               .host("*.circuitbreaker.com") //只要主机是 *.circuitbreaker.com ，就将请求路由到httpbin
               .filters(f -> f.circuitBreaker(config -> config
                                              .setName("mycmd") // 使用配置对象设置circuitBreaker，此处设置名称
                                              .setFallbackUri("forward:/fallback"))) // 设置超时时使用的url
               .uri("http://httpbin.org:80"))
        .build();
}
  • 当断路器包装的路由超时时，它会在网关应用程序中调用/fallback。现在我们可以将/fallback端点（endpoint）添加到我们的应用程序中
  • 给执行类添加RestController注解，并在执行类中添加如下内容
@RequestMapping("/fallback")
public Mono<String> fallback() {
    return Mono.just("fallback");
}
  • 重启服务，重新请求http://localhost:8080/delay/3，获得响应正文fallback

使用可配置的URI

  • 刚才的URI是写死在代码里的，现在改成可配置的
  • 在src/main/java/com/example/springcloudgatewayofficialdemo/SpringCloudGatewayOfficialDemoApplication.java中添加UriConfiguration类
  • 为启用ConfigurationProperties，在主类中添加注解@EnableConfigurationProperties(UriConfiguration.class)
@ConfigurationProperties
class UriConfiguration {

    private String httpBin = "http://httpbin.org:80";

    public String getHttpBin() {
        return httpBin;
    }

    public void setHttpBin(String httpBin) {
        this.httpBin = httpBin;
    }
}
  • 在方法中使用配置类
@SpringBootApplication
@RestController
@EnableConfigurationProperties(UriConfiguration.class) // 启用配置类
public class SpringCloudGatewayOfficialDemoApplication {

    public static void main(String[] args) {
        SpringApplication.run(SpringCloudGatewayOfficialDemoApplication.class, args);
    }

    @Bean
    public RouteLocator myRoutes(RouteLocatorBuilder builder, UriConfiguration uriConfiguration) {
        String httpUri = uriConfiguration.getHttpBin(); // 使用配置类
        // return builder.routes().build();
        return builder.routes()
                .route(p -> p
                        .path("/get") // 请求路径
                        .filters(f -> f.addRequestHeader("Hello", "World")) // 拦截器
                        .uri(httpUri)) // 使用配置类
                .route(p -> p
                        .host("*.circuitbreaker.com") //只要主机是 *.circuitbreaker.com ，就将请求路由到httpbin
                        .filters(f -> f.circuitBreaker(config -> config
                                .setName("mycmd") // 使用配置对象设置circuitBreaker，此处设置名称
                                .setFallbackUri("forward:/fallback"))) // 设置超时时使用的url
                        .uri(httpUri)) // 使用配置类
                .build();
    }

    @RequestMapping("/fallback")
    public Mono<String> fallback() {
        return Mono.just("fallback");
    }
}
  • 请求测试正常

编写测试

  • 修改src/test/java/com/example/springcloudgatewayofficialdemo/SpringCloudGatewayOfficialDemoApplicationTests.java
package com.example.springcloudgatewayofficialdemo;

import org.junit.jupiter.api.Test;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.test.context.SpringBootTest;
import org.springframework.cloud.contract.wiremock.AutoConfigureWireMock;
import org.springframework.test.web.reactive.server.WebTestClient;

import static com.github.tomakehurst.wiremock.client.WireMock.aResponse;
import static com.github.tomakehurst.wiremock.client.WireMock.get;
import static com.github.tomakehurst.wiremock.client.WireMock.stubFor;
import static com.github.tomakehurst.wiremock.client.WireMock.urlEqualTo;
import static org.assertj.core.api.Assertions.assertThat;

@SpringBootTest(webEnvironment = SpringBootTest.WebEnvironment.RANDOM_PORT,
        properties = {"httpbin=http://localhost:${wiremock.server.port}"})
@AutoConfigureWireMock(port = 0)
class SpringCloudGatewayOfficialDemoApplicationTests {

    @Autowired
    private WebTestClient webClient;

    @Test
    public void contextLoads() throws Exception {
        //Stubs
        stubFor(get(urlEqualTo("/get"))
                .willReturn(aResponse()
                        .withBody("{\"headers\":{\"Hello\":\"World\"}}")
                        .withHeader("Content-Type", "application/json")));
        stubFor(get(urlEqualTo("/delay/3"))
                .willReturn(aResponse()
                        .withBody("no fallback")
                        .withFixedDelay(3000)));

        webClient
                .get().uri("/get")
                .exchange()
                .expectStatus().isOk()
                .expectBody()
                .jsonPath("$.headers.Hello").isEqualTo("World");

        webClient
                .get().uri("/delay/3")
                .header("Host", "www.circuitbreaker.com")
                .exchange()
                .expectStatus().isOk()
                .expectBody()
                .consumeWith(
                        response -> assertThat(response.getResponseBody()).isEqualTo("fallback".getBytes()));
    }
}
  • 测试利用了Spring Cloud Contract的WireMock，建立了一个可以模拟HTTPBin的API的服务器。注意@AutoConfigureWireMock(port = 0)，这个注解为我们在一个随机端口上启动 WireMock
  • 接下来利用 UriConfiguration 类，将@SpringBootTest注释中的 httpbin 属性设置为本地运行的 WireMock 服务器。在测试中，我们为通过网关调用的 HTTPBin API 设置“存根”，并模拟我们预期的行为。
  • 运行测试，使用WebTestClient向网关发出请求并验证响应，测试结果如下
