Spring Boot - Building a RESTful Web Service with MySql access

I send a request to the rest-api to store a object into mysql database.

Which step is missing that i can store via Jpa the objects into my database?

Here is the Rest-Controller

@RestController
public class OwnerRestController {
    @Autowired
    private final OwnerRestRepository repo;

    public OwnerRestController(OwnerRestRepository repo) {this.repo = repo;}

    @RequestMapping(value="/owner/add", method=RequestMethod.POST)
    public Owner create(@RequestBody Map<String, String> body){
        Owner o = new Owner();
        o.setFirstName(body.get("firstName"));
        o.setLastName(body.get("lastName"));
        o.setAddress(body.get("address"));
        o.setCity(body.get("city"));
        o.setTelephone(body.get("telephone"));
        this.repo.save(o);
        return o;
    }
}

Here is the Repository Interface

public interface OwnerRestRepository extends CrudRepository<Owner,integer>{}

Here is the JSON-Object Owner

{
    "firstName":"fname",
    "lastName":"lname",
    "address":"address1",
    "city":"city1",
    "telephone":"4711"
}

Server Response

{
    "id": 11,
    "firstName": "fname",
    "lastName": "lname",
    "address": "address1",
    "city": "city1",
    "telephone": "4711"
}

What's wrong in the code that the data can't be stored in the database?

Best regards, Mux

By default Spring runs the in-memory database - H2, so your items only exist when your application is running.
To persist your data you need to configure the application to use another database.

To query H2 you can also use The H2 Console Application

For example if you want to configure MySQL you should have add following configuration options to your application.properties file.

spring.datasource.url=jdbc:mysql://localhost/test
spring.datasource.username=dbuser
spring.datasource.password=dbpass
spring.datasource.driver-class-name=com.mysql.jdbc.Driver

In case your are using application.yml

spring:
  datasource:
    driverClassName: com.mysql.jdbc.Driver
    url: jdbc:mysql://localhost/test
    username: dbuser
    password: dbpass
