使用Zuul和Eureka自动配置路由

问题描述

通过阅读各种书籍/教程，当将其与Eureka服务发现结合使用时，似乎可以在Zuul中自动配置路由.这意味着我不必显式添加到Zuul的application.properties的路由.

Through reading various books / tutorials, it appears that it is possible to auto-configure routes in Zuul when using it in combination with Eureka service discovery. That means that I don't have to explicitly add routes to Zuul's application.properties.

所以我正确理解了吗?还是我仍然需要显式添加到Zuul的路由才能使其用作网关?

So I understand this correctly? Or do I still need to add routes explicitly to Zuul in order it to work as a gateway?

我希望它根据在Eureka中注册的应用程序名称自动创建路由.这可能吗?

I would like it to automatically create routes from the application name's that are registered with Eureka. Is this possible?

(注意:我实际上已经尝试过，但是当我进入 http://localhost:8762/路线，我只会看到一个错误页面.)

(Note: I have actually tried this, but when I go to http://localhost:8762/routes I just get an error page.)

推荐答案

好的.在大多数微服务实现中，内部微服务端点不会暴露在外部.一组公共服务将使用API​​网关向客户端公开.

Sure. In most microservices implementations, internal microservices endpoints are not exposed outside. A set of public services will be exposed to the clients using an API gateway.

zuul代理内部使用 Eureka服务器进行服务发现.

The zuul proxy internally uses the Eureka Server for service discovery.

好的.我将向您展示网关示例.

Sure. I will show you gateway example.

1.创建您的服务项目(用户服务)

创建application.properties文件

create application.properties file

# --- Spring Config
spring:
  application:
    name: OVND-USER-SERVICE

# Eureka client
eureka:
  client:
    serviceUrl:
      defaultZone: ${EUREKA_URL:http://localhost:8761/eureka/}

2.设置Zuul项目(网关服务)

1. @ EnableZuulproxy告诉Spring Boot这是一个Zuul代理

1.@EnableZuulproxy to tell Spring Boot that this is a Zuul proxy

@SpringBootApplication
@EnableZuulProxy
@EnableDiscoveryClient
public class GatewayServiceApplication {

2.创建一个application.properties文件

2.create an application.properties file

# =======================================
# Gateway-service Server Configuration
# =======================================

# --- Spring Config
spring:
  application:
    name: gateway-service

server:
  port: ${PORT:8080}

# Eureka client
eureka:
  client:
    serviceUrl:
      defaultZone: ${EUREKA_URL:http://localhost:8761/eureka/}

zuul:
  host:
  routes:
    ## By default, all requests to user service for example will start with: "/user/"
    ## What will be sent to the user service is what comes after the path defined,
    ## So, if request is "/user/v1/user/tedkim", user service will get "/v1/user/tedkim".
    user-service:
      path: /user/**
      service-id: OVND-USER-SERVICE
    another-service:
      path: /another/**
      service-id: OVND-ANOTHER-SERVICE

Eureka网站(localhost:8761)
