如何从java代码修改现有docker-compose文件

import java.io.BufferedReader;
import java.io.BufferedWriter;
import java.io.FileReader;
import java.io.FileWriter;
import java.io.IOException;

public class DockerComposeModifier {
    public static void main(String[] args) {
        String filePath = "path/to/docker-compose.yml";
        
        try {
            // 读取docker-compose文件
            BufferedReader reader = new BufferedReader(new FileReader(filePath));
            StringBuilder content = new StringBuilder();
            String line;
            while ((line = reader.readLine()) != null) {
                content.append(line).append("\n");
            }
            reader.close();
            
            // 修改docker-compose文件的配置
            String modifiedContent = content.toString().replace("old_value", "new_value");
            
            // 写入修改后的内容到docker-compose文件
            BufferedWriter writer = new BufferedWriter(new FileWriter(filePath));
            writer.write(modifiedContent);
            writer.close();
            
            System.out.println("docker-compose文件修改成功！");
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
}
