ApiHug 整个工具链基于 Gradle, 使用 ApiHug 准备工作最先需要学习的就是 gradle. 工欲善其事,必先利其器

参考： BOM 版本open in new window + 版本字段open in new window 。

#init


gradle init

org.springframework.bootopen in new window 主要是各种Job gradle tasks 里面 boot 开头的job 都是:

打包成可执行jar、war
引入以来管理 spring-boot-dependencies 也就是： BOM_COORDINATES

public static final String BOM_COORDINATES = "org.springframework.boot:spring-boot-dependencies:"
   + SPRING_BOOT_VERSION;

gradle tasks

Application tasks
-----------------
bootRun - Runs this project as a Spring Boot application.

Build tasks
-----------
bootBuildImage - Builds an OCI image of the application using the output of the bootJar task
bootJar - Assembles an executable jar archive containing the main classes and their dependencies.
bootJarMainClassName - Resolves the name of the application's main class for the bootJar task.
bootRunMainClassName - Resolves the name of the application's main class for the bootRun task.

io.spring.dependency-managementopen in new window，主要是依赖控制： A Gradle plugin that provides Maven-like dependency management and exclusions，提供和maven 里面 pom 类似操作。

这两个插件一般是组合使用， dependency-management 依赖 boot 的 pom 版本。


plugins {
  id 'org.springframework.boot' version '2.7.0'
  id 'io.spring.dependency-management' version '1.0.11.RELEASE'
  id 'java'
}

BOM 版本open in new window + 版本字段open in new window 。两个plugin 有什么关系？

当 io.spring.dependency-management 插件被加入的时候, Spring Boot 插件将自动导入 spring-boot-dependencies bom，也就是避免导入starter 时候设置版本号（pom 的本质和好处）。

相当于自动导入了：

dependencyManagement {
  imports {
    mavenBom "org.springframework.boot:spring-boot-dependencies:${SPRING_BOOT_VERSION}"
  }
}

spring.boot 插件是避免带入版本号，如果你只想使用 spring.boot 的版本依赖，但是不想引用 spring.boot 的定制的一些task 比如 boot jar(比如定制spring starter); 有两种方式。

#第0种

plugins {
  id 'org.springframework.boot' version '2.7.0'
  id 'io.spring.dependency-management' version '1.0.11.RELEASE'
  id 'java'
}


ext {
  set('springCloudVersion', "2021.0.3")
  set('testcontainersVersion', "1.17.2")
}

dependencies {
  implementation 'org.springframework.boot:spring-boot-starter-web'
  implementation 'org.springframework.cloud:spring-cloud-starter-config'
  testImplementation 'org.springframework.boot:spring-boot-starter-test'
  testImplementation 'org.testcontainers:junit-jupiter'
}

dependencyManagement {
  imports {
    //不需要显式的导入 boot-dependencies 
    mavenBom "org.testcontainers:testcontainers-bom:${testcontainersVersion}"
    mavenBom "org.springframework.cloud:spring-cloud-dependencies:${springCloudVersion}"
  }
}

#第一种

plugins {
	id 'java'
	id("org.springframework.boot") version "2.7.0" apply false
	id("io.spring.dependency-management") version "1.0.11.RELEASE"
}

dependencyManagement {
	imports {
		mavenBom(org.springframework.boot.gradle.plugin.SpringBootPlugin.BOM_COORDINATES)
	}
}

apply false 表示不带task过来，那么下面 SpringBootPlugin.BOM_COORDINATES 同样带来导入 boot bom 效果:


public static final String BOM_COORDINATES = "org.springframework.boot:spring-boot-dependencies:"
			+ SPRING_BOOT_VERSION;

默认引入了tasks:

gradle tasks

Application tasks
-----------------
bootRun - Runs this project as a Spring Boot application.

Build tasks
-----------
bootBuildImage - Builds an OCI image of the application using the output of the bootJar task
bootJar - Assembles an executable jar archive containing the main classes and their dependencies.
bootJarMainClassName - Resolves the name of the application's main class for the bootJar task.
bootRunMainClassName - Resolves the name of the application's main class for the bootRun task.

一旦 apply false， bootRun 开头的所有任务就没有了！

#第二种

用 gradle 原生的 platform 功能

plugins {
	id 'java'
	id("org.springframework.boot") version "2.7.0" apply false
}

dependencies {
	implementation platform(org.springframework.boot.gradle.plugin.SpringBootPlugin.BOM_COORDINATES)
}

#两种方式差别

用 spring 的 dependency 或者 gradle platform 有什么差别？

#Spring Depedencies Management Plugin

Spring depedency management 提供了编辑通道:


ext['slf4j.version'] = '1.7.20'

#Gradle Platform

纯 gradle 方式:


configurations.all {
	resolutionStrategy.eachDependency { DependencyResolveDetails details ->
		if (details.requested.group == 'org.slf4j') {
			details.useVersion '1.7.20'
		}
	}
}

org.springframework.boot 和 boot 一致， io.spring.dependency-management 一般配合使用， dependency-management 会使用 boot 的版本。
