How can Spring Boot invoke an API to save data?

The general steps for calling an API to save data in Spring Boot are as follows:

1. Create an interface class to define methods for saving data. For example:

public interface DataRepository {
    void saveData(Data data);
}

1. Create a class that implements the methods in the interface. For example:

@Repository
public class DataRepositoryImpl implements DataRepository {
    @Override
    public void saveData(Data data) {
        // 保存数据的具体逻辑
    }
}

1. In places where data needs to be stored, inject the DataRepository into the class using the @Autowired annotation. For example:

@Service
public class DataService {
    @Autowired
    private DataRepository dataRepository;

    public void saveData(Data data) {
        dataRepository.saveData(data);
    }
}

1. Call the saveData method where data needs to be stored. For example:

@RestController
public class DataController {
    @Autowired
    private DataService dataService;

    @PostMapping("/data")
    public void saveData(@RequestBody Data data) {
        dataService.saveData(data);
    }
}

The above is a basic example, and the specific implementation can be adjusted and expanded according to specific needs.
