SpringCloud Zuul：如何配置多路由指向同一服务（无**通配符）

Great question! Let's break down why your second configuration approach failed and how to fix this properly.

Why the Key-Value Format Fails #

The root issue comes down to how Zuul stores route configurations. If you look into the ZuulProperties class, you'll notice that zuul.routes is a Map with this explicit comment:

Map of route names to properties.

When you use the key-value format (zuul: routes: 服务名: 路径), you’re using the service ID as the map key. Since maps can’t have duplicate keys, adding a second route with the same service ID will overwrite the first one—this is exactly why your /first route got replaced by /second.

The Correct Solution: Object Format with Unique Route Names #

The first configuration style you tested (object format) is the right approach because it lets you define unique custom route names as the map keys. Each name maps to its own route configuration with a distinct path and shared serviceId, so multiple routes can target the same service without overwriting each other.

Example Working Configuration

zuul:
  routes:
    user-service-route-first:
      path: /first/**
      serviceId: your-target-service
    user-service-route-second:
      path: /second/**
      serviceId: your-target-service

• user-service-route-first and user-service-route-second are arbitrary but unique route names (you can name them anything, as long as they don’t repeat)
• Each route has its own specific path (no global ** wildcard required—you can use precise paths like /first/api or wildcarded paths like /second/** based on your needs)
• Both routes point to the same serviceId, so requests to either /first/... or /second/... will be routed to your target service.

Quick Summary #

• Skip the key-value format for multiple routes to the same service: it relies on service IDs as map keys, which causes overwrites.
• Stick to the object format with unique route names: this aligns with Zuul’s intended map structure (route names → route properties) and lets you configure as many routes to the same service as you need.
