Quickly set up Spring source reading environment

Install gradle environment

Prerequisites Gradle environment reference installation blog

Clone Spring source code

GitHub’s Spring projectCloning from GitHub may be too slow. Use the code cloud to pull and then clone

The installation

Build a Gradle project

Execute gradlew. Bat down from the project directory

Configuring a Mirror Source

Go to the build.gradle directory of your project. In order to quickly download the related packages, it is best to add a domestic image source

repositories {
	mavenCentral()
	maven { url "https://maven.aliyun.com/repository/public" }
	maven { url "https://repo.spring.io/libs-spring-framework-build" }
}
Copy the code

The idea of configuration

Idea After configuring gradle tool, configure and import the project. Gradle tool automatically downloads the packageOnce the download is complete, proceed to build ProjectWhen done, the source code should be in the post-build folderInside is the compiled class file

test

After setting up the reading environment, write a test case

Create a submodule

Configure the required modules

Locate the module you created and go to build.gradle in the module directory

Plugins {id 'Java'} group 'org. springFramework 'version '5.2.15. build-snapshot' sourceCompatibility = 1.8 repositories  { mavenCentral() } dependencies { compile(project(":spring-context")) testCompile group: 'junit', name: 'junit, version:' 4.12 '}Copy the code

Run the test
