通过java代码启动和停止postgreSQL服务

import java.io.IOException;

public class StartPostgreSQL {
    public static void main(String[] args) {
        try {
            ProcessBuilder pb = new ProcessBuilder("pg_ctl", "start", "-D", "/path/to/postgresql/data");
            Process process = pb.start();
            int exitCode = process.waitFor();
            if (exitCode == 0) {
                System.out.println("PostgreSQL服务已成功启动");
            } else {
                System.out.println("启动PostgreSQL服务失败");
            }
        } catch (IOException | InterruptedException e) {
            e.printStackTrace();
        }
    }
}
