This is a sample Java / Maven / Spring Boot application which provides RESTful services. It can be used as a starter project. Currently it is designed to work as this project's backend.

You can import the project as a maven application to your favorite IDE. I made my tests by using eclipse jee-2018-12.

If lombok gets in your way, by referring this answer, you can install lombok by its jar file.

Use one of the several ways of running a Spring Boot application. Below are just three options:

1. Build using maven goal (or by using maven wrapper): mvn clean package and execute the resulting artifact as follows java -jar BankApplicationBackend-0.0.1-SNAPSHOT.jar or
2. On Unix/Linux based systems: run mvn clean package then run the resulting jar as any other executable ./BankApplicationBackend-0.0.1-SNAPSHOT.jar
3. Run as a Docker container.
   1. Clone the repository.
   2. cd to project root directory.
   3. docker build -t demo/bankapp .
   • If you get a ./mvnw not found error, just run mvn -N io.takari:maven:wrapper -Dmaven=3.5.3 while in the root directory of the project.
   4. docker run --expose 8080 -p 8080:8080 demo/bankapp

1. Create a user with /api/user/create url.

`$ curl -X POST localhost:8080/api/user/create -d "{\"username\": \"yourUsername\", \"password\": \"yourPassword\", \"tcno\": \"12512561125\"}" -H "Content-Type:application/json"`

You'll get a response as in below.

`{"username":"yourUsername","tcno":"12512561125"}`

2. Generate an access token by /api/login url.

$ curl -H "Content-Type: application/json" -X POST -d "{\"username\": \"yourUsername\", \"password\": \"yourPassword\"}" http://localhost:8080/api/login

You'll be getting an access token similar to this.

3. Use the token to access content available to all authenticated users, through the RESTful API.

Http.Get request example: curl -i -H "Accept: application/json" -H "Authorization: Bearer eyJ0eXAiOiJKV1QiLCJhbGciOiJIUzUxMiJ9.eyJzdWIiOiJ5b3VyVXNlcm5hbWUiLCJleHAiOjE1NTI0NDMzNjZ9.0WSCg4vaP7BVeJz8tQnL3s-BYjBB6UWXlQKCZHm1_zqEVIiA8_71Ni7tbPDm2DbW-Qc_fPP9CQF1jKcRC9njFQ" -X GET http://localhost:8080/api/user/find/all

Http.Post request example: curl -H "Content-Type: application/json" -H "Authorization: Bearer eyJ0eXAiOiJKV1QiLCJhbGciOiJIUzUxMiJ9.eyJzdWIiOiJ5b3VyVXNlcm5hbWUiLCJleHAiOjE1NTI0NDMzNjZ9.0WSCg4vaP7BVeJz8tQnL3s-BYjBB6UWXlQKCZHm1_zqEVIiA8_71Ni7tbPDm2DbW-Qc_fPP9CQF1jKcRC9njFQ" -X POST -d "{\"username\": \"yourUsername\", \"buying\": \"true\", \"currency\": \"USD\", \"amount\": \"250\"}" http://localhost:8080/api/transaction/create
