如何在spring应用程序中动态修改application.properties文件？

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter</artifactId>
</dependency>

import org.springframework.boot.context.properties.ConfigurationProperties;
import org.springframework.stereotype.Component;

@Component
@ConfigurationProperties(prefix = "your.prefix")
public class AppConfig {
    private String property1;
    private int property2;

    // Getters and setters
}

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;

@Service
public class YourService {
    private final AppConfig appConfig;

    @Autowired
    public YourService(AppConfig appConfig) {
        this.appConfig = appConfig;
    }

    public void updatePropertyValues() {
        // 修改属性值
        appConfig.setProperty1("new value");
        appConfig.setProperty2(123);
    }
}

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.ResponseBody;

@Controller
public class YourController {
    private final AppConfig appConfig;

    @Autowired
    public YourController(AppConfig appConfig) {
        this.appConfig = appConfig;
    }

    @GetMapping("/property1")
    @ResponseBody
    public String getProperty1() {
        return appConfig.getProperty1();
    }
}
