IDEA 搭建Spring源码环境

参考链接：Idea 搭建Spring源码环境

clone项目

1. 项目地址：Spring-Framework；
2. 切换分支：git checkout -b 5.2.x origin/5.2.x
3. 源码目录下有个import-into-idea.md，介绍关于导入idea的步骤以及注意事项；

IDEA导入

编译spring-oxm模块

源码目录下执行./gradlew :spring-oxm:compileTestJava

将源码导入IDEA

File -> New -> Project from Existing Sources -> build.gradle，项目将自动下载依赖包并编译：

导入后验证

注：引入自定义模块放入SpringFramework项目下

右击项目 -> New -> Module...，选择gradle项目，新建项目spring-demo，在dependencies中增加如下依赖

dependencies {
    testImplementation \'org.junit.jupiter:junit-jupiter-api:5.6.0\'
    testRuntimeOnly \'org.junit.jupiter:junit-jupiter-engine\'

    compile(project(":spring-beans"))
    compile(project(":spring-context"))
    compile(project(":spring-core"))
    compile(project(":spring-expression"))
}

然后检查settings.gradle是否有include \'spring-demo\'，有的话说明新加模块被添加进来了。

最后编写测试代码验证：

// Persion.java
public class Person {
	private String name;
	private int age;

	public String getName() {
		return name;
	}

	public void setName(String name) {
		this.name = name;
	}

	public int getAge() {
		return age;
	}

	public void setAge(int age) {
		this.age = age;
	}

	@Override
	public String toString() {
		return "Person{" +
				"name=\'" + name + \'\\\'\' +
				", age=" + age +
				\'}\';
	}
}
//Main.java
public class Main {
	public static void main(String[] args) {
		ApplicationContext context = new ClassPathXmlApplicationContext("spring.xml");
		Person person = context.getBean(Person.class);
		System.out.println(person);
	}
}

resource目录下添加配置文件spring.xml

<?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 class="org.springframework.demo.Person" id="person">
		<property name="name" value="johnny"/>
		<property name="age" value="10"/>
	</bean>
</beans>

输出如下内容表示环境搭建成功：

后面就可以在此基础上debug调试代码了:)
