In Spring property (or yaml) files we can reference other properties using the ${..} syntax.
For example:
1 2 3 | external.host=https://api.external.comexternal.productService=${external.host}/product-serviceexternal.orderService=${external.host}/order-service |
If we now access the external.productService property (e.g. by using the @Value annotation) we will get the value https://api.external.com/product-service.
For example:
1 2 | @Value("${external.productService}") |
This way we can avoid duplication of commonly used values in property and yaml files.
