4+
# Use this file to prevent files from being overwritten by the generator.
5+
# The patterns follow closely to .gitignore or .dockerignore.
6+
7+
# As an example, the C# client generator defines ApiClient.cs.
8+
# You can make changes and tell OpenAPI Generator to ignore just this file by uncommenting the following line:
9+
#ApiClient.cs
10+
11+
# You can match any string of characters against a directory, file or extension with a single asterisk (*):
12+
#foo/*/qux
13+
# The above matches foo/bar/qux and foo/baz/qux, but not foo/bar/baz/qux
14+
15+
# You can recursively match patterns against a directory, file or extension with a double asterisk (**):
16+
#foo/**/qux
17+
# This matches foo/bar/qux, foo/baz/qux, and foo/bar/baz/qux
18+
19+
# You can also negate patterns with an exclamation (!).
20+
# For example, you can ignore all files in a docs folder with the file extension .md:
21+
#docs/*.md
22+
# Then explicitly reverse the ignore rule for a single file:
23+
#!docs/README.md

# OpenAPI generated server
2+
3+
Spring Boot Server
4+
5+
## Overview
6+
This server was generated by the [OpenAPI Generator](https://openapi-generator.tech) project.
7+
By using the [OpenAPI-Spec](https://openapis.org), you can easily generate a server stub.
8+
This is an example of building a OpenAPI-enabled server in Java using the SpringBoot framework.
9+
10+
11+
The underlying library integrating OpenAPI to Spring Boot is [springdoc](https://springdoc.org).
12+
Springdoc will generate an OpenAPI v3 specification based on the generated Controller and Model classes.
13+
The specification is available to download using the following url:
14+
http://localhost:8080/v3/api-docs/
15+
16+
Start your server as a simple java application
17+
18+
You can view the api documentation in swagger-ui by pointing to
19+
http://localhost:8080/swagger-ui.html
20+
21+
Change default port value in application.properties
