# 简述： #

1.  不能忍受慢(看到这里你就准备笑吧！！)
2.  其他大神的博客实在让我难受
3.  自己动手，下载spring，编译spring源码，导入idea,开启学习模式！！
4.  笔者环境：java1.8.0\_181，gradle 5.6.3，idea2019.2.4

## 1.下载spring源码： ##

github地址：[https://github.com/spring-projects/spring-framework][https_github.com_spring-projects_spring-framework]  
码云地址：[https://gitee.com/LSZYAB/spring-framework.git][https_gitee.com_LSZYAB_spring-framework.git]  
笔者的码云地址中:加上了测试案例，帮助断点调试源码！

github的童鞋，很慢！码云的童鞋飞起！！但是笔者给的是spring5.1.x的，想要看低版本的怎么办？  
给个老铁的链接：

## 2.安装gradle： ##

1.  官网(慢)：[http://gradle.org/downloads][http_gradle.org_downloads]
2.  下载地址(快)：[https://services.gradle.org/distributions/][https_services.gradle.org_distributions]  
    ![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3FxXzQwNjcwOTQ2_size_16_color_FFFFFF_t_70 2]
3.  解压：

4.  环境配置：  
    新建系统变量：

GRADLE_HOME
    E:\install-dev\gradle-5.6.3    ## 修改为自己的路径

![在这里插入图片描述][20191109182730412.png]  
Path中添加信息：

%GRADLE_HOME%\bin

![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3FxXzQwNjcwOTQ2_size_16_color_FFFFFF_t_70 4]

cmd查看gradle版本：`gradle -v`  
![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3FxXzQwNjcwOTQ2_size_16_color_FFFFFF_t_70 5]

1.  修改gradle配置：  
    gradle根目录:**\\init.d\\下**，新建一个：**init.gradle** 文件，添加以下内容(为了下载包更快呗！)  
    ![在这里插入图片描述][20191109183352365.png]

allprojects{ 
        repositories { 
            def REPOSITORY_URL = 'http://maven.aliyun.com/nexus/content/groups/public/'
            all {  ArtifactRepository repo ->
                def url = repo.url.toString()
                if ((repo instanceof MavenArtifactRepository) && (url.startsWith('https://repo1.maven.org/maven2') || url.startsWith('https://jcenter.bintray.com'))) { 
                    project.logger.lifecycle 'Repository ${repo.url} replaced by $REPOSITORY_URL .'
                    remove repo
                }
            }
            maven { 
                url REPOSITORY_URL
            }
        }
    }

1.  修改spring源码根目录下**build.gradle**文件：将原来的信息替换成以下的信息

allprojects { 
    			repositories { 
    				maven{  url 'http://maven.aliyun.com/nexus/content/groups/public/'}
    			}
    		}

![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3FxXzQwNjcwOTQ2_size_16_color_FFFFFF_t_70 6]

## 3.构建源码： ##

1.  在源码根目录有一个文件：**import-into-idea.md**(别理它,我们继续！！)

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

cmd到spring源码下：执行`gradlew :spring-oxm:compileTestJava`，然后体验一下速度吧！！

出现如图所示的，构建成功了！接下来导入idea了！！

## 4.导入idea: ##

1.  File -> New -> Project from Existing Sources -> 找到选择spring-framework源码 -> 选择build.gradle
2.  笔者的打开之后，idea配置gradle: File->setting->gradle  
    ![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3FxXzQwNjcwOTQ2_size_16_color_FFFFFF_t_70 8]  
    点击ok,右下角开始加载包，但是还是慢！！最后修改：**gradle.properties**配置文件：

org.gradle.daemon=true
    org.gradle.jvmargs=-Xmx2048m -XX:MaxPermSize=512m -XX:+HeapDumpOnOutOfMemoryError -Dfile.encoding=UTF-8
    org.gradle.parallel=true
    org.gradle.configureondemand=true

在JDK1.8中-XX:MaxPermSize=512m无效，因为JDK1.8没有永久代的说法，取而代之的是元空间概念，因此可以改为：-XX:MaxMetaspaceSize=512m，设置参数主要是编译下载包会占用大量的内存，可能会内存溢出。笔者会写相关的文章哦!!

好了！！笔者没有花几个小时下载包，构建的时候也没出现什么问题，人品比较好，江湖再见！！  
(如果你直接下拉我的码云：对不住了！！我已经构建好了，直接导入idea吧，但是记得走**修改gradle配置**，让它更‘快！！！’)
