gradle-spring源码构建_gradle构建spring源码

1.准备环境

1.1 下载spring源码

下载spring源码。通过idea直接打开，如果有build直接关掉build,因为在没改配置前，build会失败

1.2 gradle版本选择

打开文件gradle-wrapper.properties，可以查看spring版本需要的gradle版本

1.3 安装gradle

下载对应的gradle版本，并安装，安装教程很多，本文不在描述，本文spring版本对应的gradle版本为Gradle 4.3.1

2.改maven仓库，构建spring

在根目录下找到build.gradle文件，全局搜下这个configurations.all，把整个都注释掉然后加上阿里云的库，不然你打完王者都还没结束

//	configurations.all {
//		// Check for updates every build
//		resolutionStrategy.cacheChangingModulesFor 0, 'seconds'
//	}
	allprojects {
		repositories {
			maven{ url 'http://maven.aliyun.com/nexus/content/groups/public'}
		}
	}

保存好，build下，等几分钟就好了

3、新增module，并测试构建是否成功

步骤：【File】->【New】->【Module…】 在Spring中添加自己的module模块，同样选择gradle构建

新建user类

package com.zx;

public class User {
	private Integer id;
	private String name;

	public User(Integer id, String name) {
		this.id = id;
		this.name = name;
	}

	public Integer getId() {
		return id;
	}

	public void setId(Integer id) {
		this.id = id;
	}

	public String getName() {
		return name;
	}

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

	@Override
	public String toString() {
		return "User{" +
				"id=" + id +
				", name='" + name + '\'' +
				'}';
	}
}

import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.ComponentScan;
import org.springframework.context.annotation.Configuration;

@Configuration
@ComponentScan
public class MyConfig {

	@Bean
	public User user() {
		return new User(1, "zx");
	}

public class Demo {

		User user = (User) context.getBean("user");
		System.out.println(user);

运行结果

到这里，恭喜你，spring源码编译成功，子模块构建成功，可以开始搞你想搞的事情了
