2-4 构建聚合工程

项目聚合图

项目分为三部分
common用于存放工具类 枚举类 等公共基础累
model用于存放bean entity dto等实体类
api用于存放controller接口

创建maven项目

聚合项目分为父工程和子工程 两者是子父继承关系
子模块可以使用父模块的所有资源 若子模块想使用子模块的资源的话 必须构建依赖
子模块与子模块是平级的关系 可以相互依赖
一个顶级工程由多个子工程组成

dependencyManagement的作用

dependencyManagement并不会导入将依赖直接导入到项目中
而是直接统一管理依赖版本 父工程只用于管理依赖关系和父子模块的关系

创建maven工程 作为父工程

导入依赖

根据pom结构图创建子工程
直接maven下一步即可

最后创建个news-service-user用于测试web项目是否正常
首先在里面写个controller 用于输出hello信息

新建application.yml 配置项目信息

server:
  port: 8003
  tomcat:
    accesslog:
      encoding: UTF-8
	# 默认上传最大为2MB 修改为-1 表示禁用最大上传 没有限制
    max-swallow-size: -1


spring:
  application:
    name: service-user
  jackson:
    date-format: yyyy-MM-dd HH:mm:ss
    time-zone: GMT+8

Main方法spring boot启动类 没有什么好说的
