Develop a web application with one endpoint, eg GET http://localhost:8080/users

This backend version of the User API application only provides a REST API. There is no UI.

git clone https://github.com/harinathk/user-api-rest.git
cd user-api-rest
./mvnw spring-boot:run

In its default configuration, User API uses an in-memory database (H2) which gets populated at startup with data. A similar setups is provided for MySql in case a persistent database configuration is needed. To run user api locally using persistent database, it is needed to change profile defined in application.properties file.

For MySQL database, it is needed to change param "h2db" to "mysql" in string

spring.profiles.active=h2db

defined in application.properties file.

Before do this, would be good to check properties defined in application-mysql.properties file.

spring.datasource.url = jdbc:mysql://localhost:3306/users?useUnicode=true
spring.datasource.username=ua
spring.datasource.password=userapi
spring.datasource.driver-class-name=com.mysql.jdbc.Driver
spring.jpa.database=MYSQL
spring.jpa.database-platform=org.hibernate.dialect.MySQLDialect
spring.jpa.hibernate.ddl-auto=none

GET http://localhost:8080/users/salary?from=0&to=4000

{
    "results": [
        {
            "name": "Isabella",
            "salary": 1731.0
        },
        {
            "name": "Tyler",
            "salary": 891.0
        },
        {

            "salary": 2607.0
        },

            "salary": 4000.0
        },
        {

            "salary": 698.0
        },
        {
            "name": "Chelsea",
            "salary": 3589.0
        }
    ]
}
