Spring源碼解析：獲取源碼

Spring工程採用Gradle作項目管理，因此咱們須要在本地安裝Gradle，個人的本地環境以下：

Windows 10 Professional
java 1.8.0_102
Gradle 3.4.1
git version 2.11.0

一. 從git上下載源碼

$ git clone https://github.com/spring-projects/spring-framework.git

二. 構建工程

2.1 導入eclipse工程

第一步，運行import-into-eclipse.bat，雙擊運行便可，Linux系統運行運行import-into-eclipse.sh

-----------------------------------------------------------------------
Spring Framework Eclipse/STS project import guide
This script will guide you through the process of importing the
Spring Framework sources into Eclipse/STS. It is recommended that you
have a recent version of the SpringSource Tool Suite (this script has
been tested against STS '2.9.2.RELEASE'), but at the minimum you will
need Eclipse + AJDT.

If you need to download and install STS, please do that now by
visiting http://springsource.org/downloads/sts

Otherwise, press enter and we will begin.
Press any key to continue. . .

-----------------------------------------------------------------------
STEP 1: Generate subproject Eclipse metadata

The first step will be to generate Eclipse project metadata for each
of the spring-* subprojects. This happens via the built-in
"Gradle wrapper" script (./gradlew in this directory). If this is your
first time using the Gradle wrapper, this step may take a few minutes
while a Gradle distribution is downloaded for you.

The command run will be:

    gradlew cleanEclipse :spring-oxm:compileTestJava eclipse -x :eclipse

Press enter when ready.
Press any key to continue. . .

第二步，導入到eclipse，按照提示的步驟操做便可：

-----------------------------------------------------------------------
STEP 2: Import subprojects into Eclipse/STS
Within Eclipse/STS, do the following:
File > Import... > Existing Projects into Workspace
     > When prompted for the 'root directory', provide E:\dev_workspace\git\zhenchao\java\workspace\eclipse\spring-framework\
     > Press enter. You will see the modules show up under "Projects"
     > All projects should be selected/checked. Click Finish.
     > When the project import is complete, you should have no errors.
When the above is complete, return here and press the enter key.

2.2 導入IntelliJ工程

第一步，在項目的spring-framework/spring-oxm目錄下，執行./gradle cleanIdea :spring-oxm:compileTestJava

$ gradle cleanIdea :spring-oxm:compileTestJava
Starting a Gradle Daemon (subsequent builds will be faster)
Generating JAR file 'gradle-api-3.4.1.jar'
:buildSrc:clean UP-TO-DATE
:buildSrc:compileJava NO-SOURCE
:buildSrc:compileGroovy
:buildSrc:processResources
:buildSrc:classes
:buildSrc:jar
:buildSrc:assemble
:buildSrc:compileTestJava NO-SOURCE
:buildSrc:compileTestGroovy NO-SOURCE
:buildSrc:processTestResources NO-SOURCE
:buildSrc:testClasses UP-TO-DATE
:buildSrc:test NO-SOURCE
:buildSrc:check UP-TO-DATE
:buildSrc:build

BUILD SUCCESSFUL

Total time: 8 mins 23.728 secs

第二步，導入IntelliJ工程:

File -> New -> Project from Existing Sources -> Navigate to directory -> Select build.gradle
