官网简介

​Spring Cloud Gateway​​该项目提供了一个用于在Spring MVC之上构建API网关的库。 Spring Cloud Gateway旨在提供一种简单而有效的方式来路由API并为他们提供横切关注点,例如:安全性,监控/指标和弹性。

Spring Cloud Gateway 官网特性


  • 基于Spring Framework 5,Project Reactor和Spring Boot 2.0构建
  • 能够匹配任何请求属性上的路由。
  • 指定路由配置属性和过滤器。
  • Hystrix Circuit Breaker集成。
  • Spring Cloud DiscoveryClient集成
  • 易于编写属性和过滤器
  • 限流
  • 路径重写

依赖

buildscript {
repositories {
maven { url = "https://plugins.gradle.org/m2/" }
maven { url = "http://maven.aliyun.com/nexus/content/groups/public/" }
jcenter()
}
dependencies {
classpath libs["spring-boot-gradle-plugin"]
}
}

apply plugin: "io.spring.dependency-management"
apply plugin: "org.springframework.boot"

bootJar {
baseName = 'capsule-gateway'
version = '1.0.0'
}

dependencyManagement {
imports {
mavenBom "org.springframework.cloud:spring-cloud-dependencies:Greenwich.SR1"
}
}

dependencies {
//compile project (":capsule-web-simple-dependency")
//implementation "org.springframework.boot:spring-boot-starter-web"
testImplementation "org.springframework.boot:spring-boot-starter-test"

//集成依赖
compile("org.springframework.cloud:spring-cloud-starter-gateway")
compile("org.springframework.cloud:spring-cloud-starter-netflix-hystrix")
compile("org.springframework.cloud:spring-cloud-starter-contract-stub-runner"){
exclude group: "org.springframework.boot", module: "spring-boot-starter-web"
}
}

注意:需要去掉​​spring-boot-starter-web​​的依赖

路由配置

​CapsuleGatewayApplication​

package com.example.gateway;

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;
import org.springframework.context.annotation.ComponentScan;

@SpringBootApplication
@ComponentScan(basePackages = "com.example")
public class CapsuleGatewayApplication {

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

​RouterConfiguration​

package com.example.gateway.router;

*/
@Configuration
public class RouterConfiguration {

@Bean
public RouteLocator myRoutes(RouteLocatorBuilder builder) {
return builder.routes()
.route(p->p.path("/get")
.filters(f->f.addRequestHeader("Hello","World"))
.uri("http://httpbin.org:80")
)
.build();
}

}

测试网关

访问​​curl http://localhost:8080/get​

返回:

{
"args": {},
"headers": {
"Accept": "*/*",
"Forwarded": "proto=http;host=\"localhost:8080\";for=\"0:0:0:0:0:0:0:1:55727\"",
//通过Filter添加的Header
"Hello": "World",
"Host": "httpbin.org",
"User-Agent": "curl/7.54.0",
"X-Forwarded-Host": "localhost:8080"
},
"origin": "0:0:0:0:0:0:0:1, 115.198.0.193, ::1",
"url": "https://localhost:8080/get"
}

设置网关跳转到自己开发的应用

@Bean
public RouteLocator myRoutes(RouteLocatorBuilder builder) {
return builder.routes()
.route(p->p.path("/get")
//过滤路由并添加Header参数
.filters(f->f.addRequestHeader("Hello","World"))
.uri("http://httpbin.org:80"))
//跳转到自定义服务的路由网关
.route(p->p.path("/capsule-flowable/demo/hi")
.uri("http://localhost:8081"))
.build();
}
