- By convention, a service with an ID of users receives requests from the proxy located at /users (with the prefix stripped). 即 在无任何配置下，默认路由为：网关服务/serviceID/** 路由到 serviceID服务下
- These simple url-routes do not get executed as a HystrixCommand, nor do they load-balance multiple URLs with Ribbon. To achieve those goals, you can specify a serviceId with a static list of servers
- You can provide a convention between serviceId and routes by using regexmapper
ApplicationConfiguration.java
@Bean
public PatternServiceRouteMapper serviceRouteMapper() {
return new PatternServiceRouteMapper(
"(?<name>^.+)-(?<version>v.+$)",
"${version}/${name}");
}
The preceding example means that a serviceId of myusers-v1 is mapped to route /v1/myusers/**

In addition to the filters described earlier, the following filters are installed (as normal Spring Beans):
-
Pre filters:
-
PreDecorationFilter: Determines where and how to route, depending on the supplied RouteLocator. It also sets various proxy-related headers for downstream requests. -
Route filters:RibbonRoutingFilter: Uses Ribbon, Hystrix, and pluggable HTTP clients to send requests. Service IDs are found in the RequestContext attribute, FilterConstants.SERVICE_ID_KEY. This filter can use different HTTP clients:- Apache HttpClient: The default client.
- Squareup OkHttpClient v3: Enabled by having the com.squareup.okhttp3:okhttp library on the classpath and setting ribbon.okhttp.enabled=true.
- Netflix Ribbon HTTP client: Enabled by setting ribbon.restclient.enabled=true. This client has limitations, including that it does not support the PATCH method, but it also has built-in retry.
SimpleHostRoutingFilter: Sends requests to predetermined URLs through an Apache HttpClient. URLs are found in RequestContext.getRouteHost().
