一、編譯前的準備

介紹下環境

jdk使用 jdk-11.0.5

idea使用2019.2.4版本

gradle使用 gradle-5.6.3

說明idea2019.3有bug，會造成源碼構建失敗

1、下載gradle配置環境變量

gradle下載地址 gradle官網（https://gradle.org/releases/）

在系統高級配置裏配置環境變量

我的gradle解壓到了

2、下載spring源碼

訪問GitHub地址https://github.com/spring-projects/spring-framework

解壓spring源碼

打開

針對build.gradle文件第3行，150行配置國內鏡像加速，

reference 地址

倉庫名稱	代理源地址	使用地址
central	https://repo1.maven.org/maven2/	https://maven.aliyun.com/repository/central 或 https://maven.aliyun.com/nexus/content/repositories/central
jcenter	http://jcenter.bintray.com/	https://maven.aliyun.com/repository/jcenter 或 https://maven.aliyun.com/nexus/content/repositories/jcenter
public	central倉和jcenter倉的聚合倉	https://maven.aliyun.com/repository/public 或https://maven.aliyun.com/nexus/content/groups/public
google	https://maven.google.com/	https://maven.aliyun.com/repository/google 或 https://maven.aliyun.com/nexus/content/repositories/google
gradle-plugin	https://plugins.gradle.org/m2/	https://maven.aliyun.com/repository/gradle-plugin 或 https://maven.aliyun.com/nexus/content/repositories/gradle-plugin
spring	http://repo.spring.io/libs-milestone/	https://maven.aliyun.com/repository/spring 或 https://maven.aliyun.com/nexus/content/repositories/spring
spring-plugin	http://repo.spring.io/plugins-release/	https://maven.aliyun.com/repository/spring-plugin 或 https://maven.aliyun.com/nexus/content/repositories/spring-plugin
grails-core	https://repo.grails.org/grails/core	https://maven.aliyun.com/repository/grails-core 或 https://maven.aliyun.com/nexus/content/repositories/grails-core
apache snapshots	https://repository.apache.org/snapshots/	https://maven.aliyun.com/repository/apache-snapshots 或 https://maven.aliyun.com/nexus/content/repositories/apache-snapshots

修改後

3行

	repositories {
		maven { url "https://maven.aliyun.com/repository/spring-plugin" }
		maven { url "https://maven.aliyun.com/nexus/content/repositories/spring-plugin" }
		maven { url "https://repo.spring.io/plugins-release" }
	}

150行處

	repositories {
	    maven { url "https://maven.aliyun.com/repository/central" }
		maven { url "https://repo.spring.io/libs-release" }
		mavenLocal()
	}

二、導入源碼

打開導入源碼

導入之後開始編譯，我第一次編譯出現如下錯誤。

修改配置

，重新build

編譯成功

編譯spring-core

編譯成功

編譯spring-context

構建成功

三、新建子模塊

下一步

下一步，finish

建立成功之後會自動打開各個子模塊

在spring-itdog字模塊中引入其他依賴

compile(project(":spring-context"))

新建掃描類

package com.hzau;

import org.springframework.context.annotation.ComponentScan;

/**
 * @ClassName MyCompentScan
 * @Description TODO
 * @Author yueyiming
 * @Date 2020/1/2 12:15
 * @Version 1.0
 * https://blog.csdn.net/hzau_itdog
 **/
@ComponentScan(basePackages = "com.hzau.**")
public class MyCompentScan {
}

新建實體類

package com.hzau;

import org.springframework.stereotype.Component;

/**
 * @ClassName MyBean
 * @Description TODO
 * @Author yueyiming
 * @Date 2020/1/2 12:14
 * @Version 1.0
 * https://blog.csdn.net/hzau_itdog
 **/
@Component
public class MyBean {
	public MyBean() {
	}
}

進行測試

package com.hzau;

import org.springframework.context.annotation.AnnotationConfigApplicationContext;

/**
 * @ClassName MyTest
 * @Description TODO
 * @Author yueyiming
 * @Date 2020/1/2 12:14
 * @Version 1.0
 * https://blog.csdn.net/hzau_itdog
 **/
public class MyTest {
	public static void main(String[] args) {
		AnnotationConfigApplicationContext context = new AnnotationConfigApplicationContext(MyCompentScan.class);
		MyBean bean = context.getBean(MyBean.class);
		System.out.println(bean);
	}
}

結果如下：
