I'm trying to implement swagger for Go-lang project. How to configure both Swagger UI(http://localhost:4545/docs) and local host(http://localhost:4545) running at the same on same port 4545. I can get response only on one interface(either swagger UI or localhost via postman at a time. Even our Dev Rest API's are configured on port 4545. How to get swagger UI up and running when the API's are already using 4545?

I'm trying to use Spring Boot to serve a REST API and a NextJS server to serve the frontend which calls that API. Right now, I have 2 separate servers (Spring on port 80 and NextJS on port 3000). What I want to do is forward any GET requests that the spring server receives that don't start with /api/ to the NextJS server so that the Spring server would act as a proxy for those routes. I know that you can run next export and serve the assets from Spring's static folder, but I need to use getServerSideProps in NextJS so that isn't an option. How can I do this in Spring Boot?
I have a spring boot web service running on localhost:8000 with an embedded Apache Tomcat.
Frontend is developed using Angular and is running on nginx and port 80. Connection between front- and back-end is established with a REST API endpoint, i.e. /v1/getdata/...
We have a static IP and outside access is OK with this configuration. But after setting a DNS record, i.e. https://x.y.com for the static IP, the spring web server does not return data and ERR_TUNNEL_CONNECTION_FAILED error is occurred in Angular, although the front-end is loaded successfully on port 80.
The only server-side configurations in Spring app is server.port=8000 and CORS configs.
I have set [STATIC-IP]:8000 and https://x.y.com:8000 for the api address in Angular but neither worked. However accessing with static IP is still working.
I think there is a problem with SSL configuration.
Any Ideas?
I am trying to deploy a simple microservice application (Spring boot) in GAE. The application has 3 services -
1. Discovery Service
2. Spring Cloud Gateway
3. Customer service
I am trying to call an API through API gateway. This works fine in local machine but getting 404 in GAE hosted application.
The URL I am using is - https://Gateway-url/customer-service/version
And corresponding YAML config is :
spring:
cloud:
gateway:
routes:
-id: customer-service
uri: https://XXXXXX.customer-service.appspot.com/
predicates:
- Path=/customer-service/**
filters:
- StripPrefix=1
The URI configured in above code snippet is - target URL of GAE service.
So When I hit the https://Gateway-url/customer-service/version url in browser, I am getting 404 error but it works if I hit the direct url https://customer-service-url/version
When I changed the API Gateway configuration in the local environment, (change uri to cloud based service uri), the issue is reproducible. So I am thinking that Gateway is not able to route the requests to App Engine Service target URL.
How can I fix this problem?
I think the problem is the url that you are using in the configuration file to route your requests.
According to google cloud documentation, to call from one service to another you should use a endpoint like this
https://VERSION_ID-dot-SERVICE_ID-dot-PROJECT_ID.REGION_ID.r.appspot.com
As yo can see here
https://cloud.google.com/appengine/docs/standard/java/communicating-between-services
And it seems that the url that you are using doesn't fit int this.
Anyway I think that in a serverless environment such as app engine the best option to perform service discovery and to route requests via gateway is using the services provided by google. In case of service discovery it is done automatically and if you want a gateway you can use google cloud endpoints that have a greate integration with app engine. Because this is the gateway intended to use with these applications
I created spring boot api with gradle build. everything working fine in my local.
I deployed angular app in Sites/DefaultsTest in IIS web server. it run in https://example.app.com/app
SpringBoot API base path is '/api'
I want to deploy spring boot api in same windows server machine and should able to access through Angular App globally.
please guide me.
IIS WebServer Dashboard
As far as I know, the spring boot API is a java web application, we don't suggest you directly hosted the java web application in the IIS.
I suggest you could try to install a docker or using tomcat to host the application, then you could use IIS reverse proxy to redirect the request to that API to get the result.
More details about how host the spring boot application on the docker, you could refer to below article.

I have an Angular application deployed to/via IIS. This app is sending requests to REST endpoints exposed by a Spring Boot application which I am running as a Windows Service (The Spring Boot application is accessing a MongoDB but this should not be relevant, I think). The exposed REST interface is accessable via port 8080 on the servers localhost.
The Angular app is accessible as it should be but there seems to be a problem when the web app tries to access the Spring Application's REST interfaces. More specific: The client seems to be receiving HTML documents when he should be receiving JSON files.
I am new to working with IIS so beginner errors are not unlikely. I'm happy to share more information if needed!
Edit: I read again the question, and understood something wrong:
Looks like you were sending requests to your Angular server. For development you should use the embedded web server (https://docs.spring.io/spring-boot/docs/current/reference/html/howto-embedded-web-servers.html) in order to ease your server configuration steps. And from within the windows server, send request to localhost:springboot_port.
Once you want your service to be available for an external client, and to keep your service available/awake (something similar to systemd in Linux), you could try this: https://www.baeldung.com/spring-boot-app-as-a-service
