IDEA工具导入Spring 源码工程

IDEA工具导入Spring 源码工程

前提条件

• JDK1.8版本
• 安装Gradle

---

下载Spring源码

进入Github，找到spring-framework源码地址。或者直接登陆到GitHub - spring-projects/spring-framework: Spring Framework这个地址官网，下载到本地磁盘

修改配置信息，为编译做准备工作

使用idea打开我们刚刚下载的Spring工程项目，使用Gradle 对Spring项目进行编译

1. 修改工程中最外边的settings.gradle文件，修改文件中的插件中的仓库信息，修改如下：

   pluginManagement {
   	repositories {
   		gradlePluginPortal()
   		mavenLocal()
   		maven { url 'https://mirrors.huaweicloud.com/repository/maven/' }
   		maven { url 'https://maven.aliyun.com/repository/public' }
   		maven { url 'https://nexus.bsdn.org/content/groups/public/' }
   		maven { url 'https://maven.aliyun.com/repository/google' }
   		maven { url 'https://maven.aliyun.com/repository/spring' }
   		maven { url 'https://maven.aliyun.com/repository/gradle-plugin' }
   		maven { url 'https://maven.aliyun.com/repository/spring-plugin' }
   		maven { url 'https://repo.huaweicloud.com/repository/maven/' }
   		maven { url 'https://repo.spring.io/plugins-release' }
   	}
   }
   

2. 修改工程中最外边的build.gradle文件，同上边修改setting.gradle一样，同样修改的也是仓库信息，具体如下：

   		repositories {
   			mavenLocal()
   			maven { url 'https://mirrors.huaweicloud.com/repository/maven/' }
   			maven { url 'https://maven.aliyun.com/repository/public' }
   			maven { url 'https://nexus.bsdn.org/content/groups/public/' }
   			maven { url 'https://maven.aliyun.com/repository/google' }
   			maven { url 'https://maven.aliyun.com/repository/spring' }
   			maven { url 'https://maven.aliyun.com/repository/gradle-plugin' }
   			maven { url 'https://maven.aliyun.com/repository/spring-plugin' }
   			maven { url 'https://repo.huaweicloud.com/repository/maven/' }
   		    maven { url "http://repo.springsource.org/plugins-release" }
   		    mavenCentral()
   		}
   

3. 修改工程中gradle目录下的build-cache-settings.gradle文件，我们使用本地缓存，关闭远端缓存信息

   buildCache {
   	local {
   		enabled = true
   	}
   	remote(HttpBuildCache) {
   		enabled = false  ## 关闭远端缓存
   		url = 'https://ge.spring.io/cache/'
   		def cacheUsername = System.getenv('GRADLE_ENTERPRISE_CACHE_USERNAME')
   		def cachePassword = System.getenv('GRADLE_ENTERPRISE_CACHE_PASSWORD')
   		if (cacheUsername && cachePassword) {
   			push = true
   			credentials {
   				username = cacheUsername
   				password = cachePassword
   			}
   		}
   	}
   }
   

---

编译工程，导入到idea中

1. 我们在下载的目录中开启cmd命令窗口，执行一下gradlew编译命令，看一下是否可以通过编译，具体执行如下命令：

   gradlew :spring-oxm:compileTestJava
   
   BUILD SUCCESSFUL in 33s
   40 actionable tasks: 22 executed, 18 up-to-date
   

2. 将结果导入到idea中，File -> New -> Project from Existing Sources -> Navigate to directory -> Select build.gradle

3. 启动时记得要排除spring-aspects module

---

在源码中创建自己的工程

1. 在源码的父工程下创建一个Gradle的子module，名称为my-spring-demo子模块。在我们修改的第一个配置文件setting.gradle的下边添加我们相关的子模块信息。

   include "spring-websocket"
   include "framework-bom"
   include "integration-tests"
   include "my-spring-demo"   ## 我们自己的项目模块
   rootProject.name = "spring"
   rootProject.children.each {project ->
   	project.buildFileName = "${project.name}.gradle"
   }
   

2. 在我们的子模块中修改自己模块中的gradle配置信息，注意： 该gradle文件必须和你的项目模块名称一致，比如我们的是my-spring-demo.gradle文件

   plugins {
       id 'java'
   }
   
   group 'org.springframework'
   version '5.2.14.BUILD-SNAPSHOT'
   
   sourceCompatibility = 1.8
   
   repositories {
       mavenCentral()
   }
   
   dependencies {
       compile(project(":spring-beans"))
       compile(project(":spring-context"))
       testCompile group: 'junit', name: 'junit', version: '4.12'
   }
   

3. 我们还是使用配置xml的方式创建一个测试案例

   public class User {
   
   	private String name;
   	private String address;
   
   	public String getName() {
   		return name;
   	}
   
   	public void setName(String name) {
   		this.name = name;
   	}
   
   	public String getAddress() {
   		return address;
   	}
   
   	public void setAddress(String address) {
   		this.address = address;
   	}
   
   	@Override
   	public String toString() {
   		return "User{" +
   				"name='" + name + '\'' +
   				", address='" + address + '\'' +
   				'}';
   	}
   }
   

   <?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="user" class="com.tenic.spring.demo1.User">
   		<property name="name" value="tenic"/>
   		<property name="address" value="www.cnblogs.com/tenic"/>
   	</bean>
   
   </beans>
   

   
   public class AppTest {
   
   	public static void main(String[] args) {
   		ClassPathXmlApplicationContext ac = new ClassPathXmlApplicationContext("applicationContext.xml");
   		User bean = ac.getBean(User.class);
   		System.out.println(bean.toString());
   
   		TestBean testBean = (TestBean) ac.getBean("testBean");
   		System.out.println(testBean.getTestStr());
   	}
   }
   

4. 直接运行该main方法，可以看到控制台中输出了我们想要的信息，如下图片展示
