【SpringBoot】仿 spring-boot-project 自定义 starters-阿里云开发者社区

1. spring-boot-project 项目分析

spring-boot-project 为 spring-boot 核心技术包，其中包含了 spring-boot 所有基础源码。
spring-boot-test 为 springboot 的测试包，包含了系统集成测试、部署测试、冒烟测试。

本文以 spring-boot-project 工程包为模板，定制一个属于自己基础工程依赖包。下面着重介绍一下 spring-boot-project 各个模块。

spring-boot：springboot 的框架基础，其中包含了 springboot 应用启动，初始化，启动 banner，springApplication定义、构建器API、应用程序事件和侦听器、应用程序启动跟踪、管理功能。

spring-boot-dependencies：空文件包，此包是对 spring-boot 进行了依赖管理。在构建大型微服务框架时常常会引入此包，统一对依赖包进行版本管理。

spring-boot-parent：此包的父类为 spring-boot-dependencies，提供了 springBoot 快速开发，和 spring-boot-dependencies 区别在于此包适合较少自定义的应用，当自己公司有自己定义的基础框架时，springboot 官网建议使用 spring-boot-dependencies 去构架，这样有利于 maven 依赖版本的管理。

spring-boot-starters：这个模块有很多 starter 子模块，平时用的也是非常多的，Starters 可以作为一组依赖配置信息放在你项目的依赖配置中。从中您可以获得所需的所有 Spring 及其相关技术的一站式服务而无需搜索项目的配置方法并复制粘贴项目所需的依赖配置信息。如果你想使用 Spring JPA 作为数据库访问中间层，仅仅需要将 spring-boot-starter-data-jpa 加入你的项目依赖中, 即可使用 Spring JPA。

其他模块如有需要大家可以去 Github 获取相关文档或源码。

2. 自定义 starters

2.1 工程结构介绍

pointer-boot-build - 即父工程，只有一个 pom 文件，主要记录一些项目信息及版本控住，这里利用 revision 占位符来统一控制版本。

pointer-boot - 自定义的框架基础，这里封装了统一响应结果、基础异常、基础错误码枚举、校验工具类等共用类，同时也引入了一些共用依赖，原则上每个新建的工程都需要引用此 module。

pointer-boot-parent - 此包的父类为 pointer-boot-dependencies，提供了 pointer-boot 快速开发，和 pointer-boot-dependencies 区别在于此包适合较少自定义的应用，这里是我自己定义的基础框架，使用 spring-boot-dependencies 去构架，这样有利于 maven 依赖版本的管理。

pointer-boot-starters - 这个模块有很多 starter 子模块，平时用的也是非常多的，Starters 可以作为一组依赖配置信息放在你项目的依赖配置中。这里我只定义了 pointer-boot-starter-web，其封装了一些 web 相关，如：全局异常捕获处理、全局格式化配置、全局响应拦截器等等。
