本文已参与「新人创作礼」活动，一起开启掘金创作之路。

环境准备

• 安装jdk，idea，maven并做好相应配置
• 操作系统：windows

Spring源码下载

Spring源码Github仓库地址为：github.com/spring-proj…

首先，选择合适的RELEASE版本，然后下载ZIP包即可

软件版本介绍：

• GA：General Availability，官方正式发布的稳定版本，同质的还有RELEASE，Stable，Final
• RC：Release Candidate，发行候选版本，基本不再加入新的功能
• Alpha：内部测试版本，bug较多，功能不全
• Beta：公开测试版，比Alpha版本晚些，还会加功能，修bug
• M：Milestone，开发期发行版本，边开发边发行

导入IDEA

import-into-idea

Within your locally cloned spring-framework working directory:

0. Precompile spring-oxm with ./gradlew :spring-oxm:compileTestJava
1. Import into IntelliJ (File -> New -> Project from Existing Sources -> Navigate to directory -> Select build.gradle)
2. When prompted exclude the spring-aspects module (or after the import via File-> Project Structure -> Modules)
3. Code away

0. 在解压缩后的源码路径下执行预编译指令：./gradlew :spring-oxm:compileTestJava

2. build.gradle 文件里配置阿里云镜像加速

buildscript {
    repositories {
        maven { url 'https://maven.aliyun.com/nexus/content/groups/public/' }
        maven { url 'https://maven.aliyun.com/repository/jcenter' }
    }
    dependencies {
        classpath 'org.asciidoctor:asciidoctorj-pdf:1.5.0-alpha.16'
        classpath 'io.spring.asciidoctor:spring-asciidoctor-extensions:0.1.3.RELEASE'
    }
}

        repositories {
            maven { url 'https://maven.aliyun.com/nexus/content/groups/public/' }
            maven { url 'https://maven.aliyun.com/repository/jcenter' }
            mavenCentral()
            maven { url "https://repo.spring.io/libs-spring-framework-build" }
        }

3. 导入IntelliJ IDEA：File -> New -> Project from Existing Sources -> Navigate to directory -> Select build.gradle

4. 排除 spring-aspects，aspects包在idea中不能完成编译，只能unload

测试

0. new Module

2. 引入spring-context项目

spring-context 包含了 spring-aop、spring-beans、spring-core 等 Spring核心

3. 简单测试

接口：

package com.uestc;
​
public interface HelloService {
    void sayHello(String name);
}

实现：

package com.uestc.Impl;
import com.uestc.HelloService;
​
public class HelloServiceImpl implements HelloService {
    @Override
    public void sayHello(String name) {
        System.out.println("Hi~" + name);
    }
}

spring-config.xml:

<?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
        https://www.springframework.org/schema/beans/spring-beans.xsd">
​
    <bean id="helloService" class="com.uestc.Impl.HelloServiceImpl"/>
​
</beans>

参考：docs.spring.io/spring-fram…

调用Main方法：

package com.uestc;
​
import org.springframework.context.ApplicationContext;
import org.springframework.context.support.FileSystemXmlApplicationContext;
​
public class Main {
    public static void main(String[] args) {
        // xml文件绝对路径
        String xmlPath = "E:\Java\javaWorkSpace\spring-framework-5.2.0.RELEASE\spring-demo\src\main\resources\spring-config.xml";
        // 解析spring的配置文件
        ApplicationContext applicationContext = new FileSystemXmlApplicationContext(xmlPath);
        // 获取配置文件的 <bean id="helloService" .... />
        HelloService helloService = (HelloService)applicationContext.getBean("helloService");
        // 调用方法
        helloService.sayHello("China");
    }
}
