2. 项目的启动文件介绍

每个服务模块通常包含一个启动类，用于启动Spring Boot应用程序。例如，在congomall-bff模块中，启动类可能位于congomall-bff-web包中，命名为BffApplication.java。启动类通常包含@SpringBootApplication注解，用于标识这是一个Spring Boot应用程序的主类。

package com.congomall.bff.web;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

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

3. 项目的配置文件介绍

每个服务模块通常包含一个或多个配置文件，用于配置应用程序的各种属性。常见的配置文件包括application.yml或application.properties。以下是一个示例配置文件的内容：

server:
  port: 8009

spring:
  application:
    name: congomall-bff
