效果

搭建一個spring源碼調試環境，創建一個spring-demo模塊，寫一些測試代碼。

給源碼添加註釋。

給源碼打包

ubantu環境下搭建spring6.0.x源碼環境

步驟

源碼網址

Spring Framework

下載代碼

fork到自己的GitHub倉庫，然後拉代碼

git clone https://github.com/GitHubXiaoSiyuan/spring-framework-6.0.7.git

代碼拉到 ~/files/projects/kernel_projects/fr
amework 目錄下

gradle下載與配置

下載

https://gradle.org/releases/

gradle/wrapper/gradle-wrapper.properties

找到版本為7.6的 gradle

distributionUrl=https\://services.gradle.org/distributions/gradle-7.6-bin.zip

找到 7.6 的版本，點擊下載（註：點擊之後，用迅雷下載很快）

下載鏈接如下（複製即可觸發迅雷下載）

https://downloads.gradle-dn.com/distributions/gradle-7.6-all.zip

解壓

sudo unzip gradle-7.6-all.zip

配置環境變數

# 設置環境變數
sudo vi /etc/profile

# 在底部加入這一段
# gradle
export GRADLE_HOME=/home/xiaosy/files/development/gradle-7.6 
export PATH=$NODE_HOME/bin:$PATH

# 變數生效
source /etc/profile

# 設置讀寫許可權
sudo chmod -R 777 /home/xiaosy/files/development/gradle-7.6/bin

# 查看版本
# 不知道為什麼直接 gradle -v 沒用
/home/xiaosy/files/development/gradle-7.6/bin/gradle -v

idea配置

配置gradle編譯

Tools -> gradle

# 路徑
壓縮包放在 /gradle/wrapper/ 目錄下

路徑配置
/home/xiaosy/files/development/gradle-7.6

下載二進位版本

https://services.gradle.org/distributions/gradle-7.6-bin.zip

jdk

設置為 jdk17

# 設置環境變數
sudo vi /etc/profile


# 修改jdk路徑
# jdk
export JAVA_HOME=/home/xiaosy/files/development/jdk17/jdk-17.0.6


# 變數生效
source /etc/profile

gradle-wrapper.properties修改

打開 gradle/wrapper/gradle-wrapper.properties

將distributionUrld地址替換為本地gradle下載

# 修改後
distributionUrl=/home/xiaosy/files/development/gradle-7.6-all.zip

build.gradle文件修改

替換國內鏡像

	repositories {
		maven { url "https://maven.aliyun.com/repository/central" }
		mavenCentral()
		maven {
			url "https://repo.spring.io/milestone"
			content {
				// Netty 5 optional support
				includeGroup 'io.projectreactor.netty'
			}
		}
		maven { url "https://repo.spring.io/libs-spring-framework-build" }
		if (version.contains('-')) {
			maven { url "https://repo.spring.io/milestone" }
		}
		if (version.endsWith('-SNAPSHOT')) {
			maven { url "https://repo.spring.io/snapshot" }
		}
	}

setting.gradle文件修改

替換國內鏡像

	repositories {
		maven {
			url 'https://maven.aliyun.com/repository/public'
		}
		maven {
			url "https://maven.aliyun.com/repository/google"
		}
		maven { url "https://maven.aliyun.com/repository/gradle-plugin/" }

		gradlePluginPortal()
		google()
		mavenCentral()
	}

註釋

//註釋掉不然會A build scan was not published as you have not authenticated with server 'ge.spring.io'.

用idea集成的gradlereload

編譯成功

新建module

在新項目的build.gradle下添加對spring模塊的依賴，這裡我先添加了spring-beans 和spring-core的依賴。

dependencies {
    compile(project(":spring-beans"))
    compile(project(":spring-core"))
    testCompile group: 'junit', name: 'junit', version: '4.12'
}

在新項目的src/main/resource下添加spring-config.xml文件

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
	   xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
	   xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd">
	<!--把對象的創建交給spring來管理-->
	<bean id="person" class="com.wts.Person">
		<property name="id" value="1"></property>
		<property name="name" value="zhangsan"></property>
	</bean>
</beans>

創建測試bean和啟動類

public class Person {

	private int id;

	private String name;

	public int getId() {
		return id;
	}

	public void setId(int id) {
		this.id = id;
	}

	public String getName() {
		return name;
	}

	public void setName(String name) {
		this.name = name;
	}
}

public class Test {

	public static void main(String[] args) {
		ApplicationContext ac = new ClassPathXmlApplicationContext("applicationContext.xml");
		Person person = (Person) ac.getBean("person");
		System.out.println(person);
	}
}

debug

1. 更改壓縮包位置

The specified Gradle distribution 'file:/home/xiaosy/files/projects/kernel_projects/framework/spring-framework-6.0.7/gradle/wrapper/home/xiaosy/files/development/gradle-7.6-all.zip' does not exist.

2

設置文件讀寫許可權

Could not create parent directory for lock file /gradle-7.6/wrapper/dists/gradle-7.6-all/cmg34oui1skho6ogkheeq1oxe/gradle-7.6-all.zip.lck

sudo chmod -R 777 ~/files/projects/kernel_projects/framework/spring-framework-6.0.7

3

Cause: zip file is empty

4

解決：

gradle.properties

org.gradle.java.home=/home/xiaosy/files/development/jdk17/jdk-17.0.6

倆 gradle.properties 都設置了

註釋掉這段代碼，然後重寫就不報錯了，純粹的編譯問題
