11. Route Metadata Configuration

You can configure additional parameters for each route by using metadata, as follows:spring-doc.cn

Example 65. application.yml
spring:
  cloud:
    gateway:
      routes:
      - id: route_with_metadata
        uri: https://example.org
        metadata:
          optionName: "OptionValue"
          compositeObject:
            name: "value"
          iAmNumber: 1

You could acquire all metadata properties from an exchange, as follows:spring-doc.cn

Route route = exchange.getAttribute(GATEWAY_ROUTE_ATTR);
// get all metadata properties
route.getMetadata();
// get a single metadata property
route.getMetadata(someKey);
