Spring Boot中通过动态键读取属性

使用Spring Boot开发应用程序时，有时候需要根据动态键来读取属性。Spring Boot提供了一种简单而灵活的方式来实现这一点。本文将介绍如何在Spring Boot中通过动态键读取属性，并提供相应的案例代码。

java
import org.springframework.beans.factory.annotation.Value;
import org.springframework.stereotype.Component;
@Component
public class MyComponent {
    @Value("${dynamic.key}")
    private String value;
    public void printValue() {
        System.out.println("Dynamic value: " + value);
    }
}

java
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
@SpringBootApplication
public class Application {
    @Autowired
    private MyComponent myComponent;
    public static void main(String[] args) {
        SpringApplication.run(Application.class, args);
    }
    public void run(String... args) {
        myComponent.printValue();
    }
}
