# 一、提前编译好Spring源码 #

## 1、安装JDK、idea、maven并做好响应的配置； ##

## 2、下载源码并编译； ##

### **[Y004番外教程-编译Spring框架-JDK13 + spring-framework v5.2.4.RELEASE + git][Y004_-_Spring_-JDK13 _ spring-framework v5.2.4.RELEASE _ git]** ###

# 二、导入IDEA #

直接主界面Import Project，选择spring-framework文件夹，IDEA经过一段时间的下载，就能导入成功；

# 三、排除 spring-aspects 模块 #

# 四、创建springdemo #

**第一步：、**

# 五、测试代码 #

# 六、第一个springdemo #

## 1、代码 ##

### IWelcomeService接口： ###

package com.zibo.service;
    
    public interface IWelcomeService {
    	String sayHello(String name);
    }

### WelcomeServiceImpl接口实现类： ###

package com.zibo.service.impl;
    
    import com.zibo.service.IWelcomeService;
    
    public class WelcomeServiceImpl implements IWelcomeService {
    	@Override
    	public String sayHello(String name) {
    		System.out.println("Hello " + name);
    		return "success";
    	}
    }

### Entrance测试类： ###

package com.zibo;
    
    import com.zibo.service.IWelcomeService;
    import org.springframework.context.support.FileSystemXmlApplicationContext;
    
    public class Entrance {
    	public static void main(String[] args) {
    		//配置文件绝对路径
    		String xmlPath = "D:\\Spring\\spring-framework\\springdemo\\src\\main\\resources\\spring\\spring-config.xml";
    		//读取配置文件
    		FileSystemXmlApplicationContext context = new FileSystemXmlApplicationContext(xmlPath);
    		//从配置文件中取出welcomeService
    		IWelcomeService welcomeService = (IWelcomeService) context.getBean("welcomeService");
    		//调用welcomeService的方法
    		welcomeService.sayHello("ZiBo");
    	}
    }

### spring-config.xml配置文件： ###

<?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">
    
    	<bean id="welcomeService" class="com.zibo.service.impl.WelcomeServiceImpl"/>
    
    </beans>

### build.gradle： ###

plugins {
        id 'java'
    }
    
    group 'io.spring.asciidoctor'
    version '5.2.5.BUILD-SNAPSHOT'
    
    sourceCompatibility = 1.8
    
    repositories {
        mavenCentral()
    }
    
    dependencies {
        compile(project(":spring-context"))
        testCompile group: 'junit', name: 'junit', version: '4.12'
    }

## 2、文件结构图 ##

## 3、运行结果 ##

# 七、学好Spring源码的建议 #

## 1、阅读Spring官方文档（Spring的文档非常详尽）； ##

## 2、多动手调试； ##

## 3、掌握设计模式，熟悉spring框架的标签和注解的作用； ##

# 八、软件版本知识点补充 #

## 1、GA：General Availability，官方正式发布的稳定版本； ##

## 2、同质的还有RELEASE，Stable，Final ##

## 3、RC：Release Candidate，发行候选版本，基本不再加入新的功能； ##

4、Alpha：内部测试版，bug较多，功能不全；

5、Beta：公开测试版，比Alpha版本晚些，还会加功能，修bug；

6、M：Milestone，开发期发行版本，边开发变发行；
