Define the Predicate

tip

The order of route execution is important. The first route whose predicate matches the request will be executed.

We now need to define the condition for the route's execution.

Let's go to the Predicates section.

info

ARCHWAY offers a collection of predicates, mostly derived from the framework it is based on, Spring cloud gateway.

The Path Route Predicate​

Here we will use the Path predicate. This means that if the path matches the predicate, the route will be executed.

Add a Path type predicate.

Enter:

  • Path: /**

This means that any routes starting with /** will execute this route.

create-route-predicate

This makes sense when the route is the default application managed by ARCHWAY. Normally, each route should be discriminated by different paths, such as /service1, /service2, etc...

note

If we had used a subpath, it would probably be appropriate to add a StripPrefix request filter to remove the route prefix.

tip

You can sort the routes by dragging and dropping.

warning

The /** route should always be in the last position. Make sure that the /** route is last on the list.

warning

Of course, each microservice should have a different predicate.
