How to define configuration file information in java

Sometimes we put some variables into the yml configuration file for unified management

For example

Use @ConfigurationProperties Instead of @Value

Use method

Define the entity of the corresponding field

@Data
// 指定前缀
@ConfigurationProperties(prefix = "developer")
@Component
public class DeveloperProperty {
    private String name;
    private String website;
    private String qq;
    private String phoneNumber;
}

Inject this bean when using

@RestController
@RequiredArgsConstructor
public class PropertyController {
 
    final DeveloperProperty developerProperty;
 
    @GetMapping("/property")
    public Object index() {
       return developerProperty.getName();
    }
}
