How to set a base url in a springboot graphql app - spring-boot

Question

How can we set a base url in springboot graphql-server app .
By default the graphiql api-console opens on http://localhost:8080/graphiql
Trying to access http://localhost:8080 through postman with a post -query as below :
{
bookings {
name
}
}
gives an error saying :
{
"timestamp": 1549913598497,
"status": 404,
"error": "Not Found",
"message": "No message available",
"path": "/"
}
Q1 what should be the path to the server i should be using to invoke it.
Q2 is there a way to provide a custom base path something loke http://localhost:8080/service/api/query

Answer 1

Usually the server path for graphql endpoints is at http://localhost:8080/graphql. If not just inspect the network tab on your browser when you run a query on your GraphiQL interface, it will run the query on the api endpoint.
In order to change the base path you would need to change application.properties into something like:
graphql.servlet.mapping: /service/api/query
graphiql.mapping: /graphiql
graphiql.endpoint: /service/api/query

Answer 2

If you are using Spring Boot Property file you can change the base url like below:
spring.graphql.path=/service/api/query
Example:
When I changed the base url like below.:
spring.graphql.path=/api/projects/graphql
It reflected like below in console:
2022-11-05 08:58:14.964 INFO 17336 --- [ main] s.b.a.g.s.GraphQlWebMvcAutoConfiguration : GraphQL endpoint HTTP POST /api/projects/graphql
