primes-generator-api

Primes Generator API implemented using Spring Boot maven

This API compute the primes between a range given by 3 different strategies:

1. BruteForce strategy

2. Sieve of Eratosthenes

3. Sieve of Sundaram

Then it records each execution in a H2 database (In memory Database) including timestamp, range, time elapsed, algorithm chosen and number of primes returned.

How to run

• Run the project using the following command line inside primegeneratorapi directory :

  mvn spring-boot:run

REST APIs Endpoint

getPrimes

Returns a list of the primes in the range and a HttpStatus.

• URL

  /getPrimes?method=:method&rLeft=:rLeft&rRight=:rRight

• getPrimes

  gets the range and the strategy.

Database

Credentials

We are using H2 Database for recording the executions.

You could set the credentials in the src/resources/application.properties file.

The default Credentials are :

• URL: jdbc:h2:mem:simscaledb

• username: sa

• password: ""

Visualize the data

To visualize the data enter the following URL and then enter the credentials.
