将spring boot应用程序属性绑定到java.util.properties

@ConfigurationProperties(prefix = "myapp")
public class MyAppProperties {
    private String name;
    private int port;
    
    // getter和setter方法省略
}

myapp.name=MyApp
myapp.port=8080

@SpringBootApplication
@EnableConfigurationProperties(MyAppProperties.class)
public class MyAppApplication {
    public static void main(String[] args) {
        SpringApplication.run(MyAppApplication.class, args);
    }
}

@RestController
public class MyController {
    private final MyAppProperties myAppProperties;
    
    public MyController(MyAppProperties myAppProperties) {
        this.myAppProperties = myAppProperties;
    }
    
    @GetMapping("/name")
    public String getName() {
        return myAppProperties.getName();
    }
    
    @GetMapping("/port")
    public int getPort() {
        return myAppProperties.getPort();
    }
}
