Swagger not working in Chapter 10

[muradhajiyev]

First of all, thank you for the useful book.

I faced an issue in Chapter 10 and afterward. So, After implementing gateway, while trying to access swagger, it says 404. Could someone help me to solve this issue? The URL I try to access for swagger is below:

http://localhost:8080/product-composite/swagger-ui/index.html or http://localhost:8080/product-composite/swagger-ui.html

Hey @muradhajiyev,

This looks like a routing problem within the gateway. Check your application.yml (or application.properties) in the gateway project.

spring.cloud.gateway.routes:

- id: product-composite
  uri: lb://product-composite
  predicates:
  - Path=/product-composite/{segment}

- id: product-composite-swagger-ui
  uri: lb://product-composite
  predicates:
  - Path=/swagger-ui.html

- id: product-composite-swagger-v2
  uri: lb://product-composite
  predicates:
  - Path=/v2/**

- id: product-composite-swagger-resources
  uri: lb://product-composite
  predicates:
  - Path=/swagger-resources/**

- id: product-composite-swagger-jars
  uri: lb://product-composite
  predicates:
  - Path=/webjars/**

...

The reason I added the extra routers is that after swagger.html loads it will ask for various other resources like .js, .css ...etc; Those need to be routed as well.

There most likely is a way of solving this in a less verbose approach. Maybe @magnus-larsson has an input here.

@mariusmagureanu Thank you. The author already uses openapi 3.0.

• id: swagger uri: lb://product-composite predicates:

  • Path=/swagger-ui/**

• id: product-composite-swagger-v2 uri: lb://product-composite predicates:

  • Path=/v2/**

• id: product-composite-swagger-resources uri: lb://product-composite predicates:

  • Path=/swagger-resources/**

it helped.
