Spring5.1源码解析（一）源码编译导入idea

我就是我 2023-06-25 06:24 94阅读 0赞

## 一、编译前的准备 ##

介绍下环境

jdk使用 jdk-11.0.5

idea使用2019.2.4版本

gradle使用 gradle-5.6.3

说明idea2019.3有bug，会造成源码构建失败

### 1、下载gradle配置环境变量 ###

gradle下载地址  [gradle官网（][gradle][https://gradle.org/releases/][gradle][）][Link 1]

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2h6YXVfaXRkb2c_size_16_color_FFFFFF_t_70][]

在系统高级配置里配置环境变量

我的gradle解压到了

###  2、下载spring源码 ###

访问GitHub地址[https://github.com/spring-projects/spring-framework][https_github.com_spring-projects_spring-framework]

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2h6YXVfaXRkb2c_size_16_color_FFFFFF_t_70 1][]

解压spring源码

打开

修改后

3行

repositories {
    		maven { url "https://maven.aliyun.com/repository/spring-plugin" }
    		maven { url "https://maven.aliyun.com/nexus/content/repositories/spring-plugin" }
    		maven { url "https://repo.spring.io/plugins-release" }
    	}

150行处

repositories {
    	    maven { url "https://maven.aliyun.com/repository/central" }
    		maven { url "https://repo.spring.io/libs-release" }
    		mavenLocal()
    	}

##  二、导入源码 ##

打开导入源码

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2h6YXVfaXRkb2c_size_16_color_FFFFFF_t_70 4][]

![20191226203018554.png][]

导入之后开始编译，我第一次编译出现如下错误。

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2h6YXVfaXRkb2c_size_16_color_FFFFFF_t_70 5][]

修改配置

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2h6YXVfaXRkb2c_size_16_color_FFFFFF_t_70 6][]

，重新build

编译成功

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2h6YXVfaXRkb2c_size_16_color_FFFFFF_t_70 7][]

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2h6YXVfaXRkb2c_size_16_color_FFFFFF_t_70 8][]

编译spring-core

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2h6YXVfaXRkb2c_size_16_color_FFFFFF_t_70 9][]

编译成功

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2h6YXVfaXRkb2c_size_16_color_FFFFFF_t_70 10][]

编译spring-context

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2h6YXVfaXRkb2c_size_16_color_FFFFFF_t_70 11][]

构建成功

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2h6YXVfaXRkb2c_size_16_color_FFFFFF_t_70 12][]

三、新建子模块

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2h6YXVfaXRkb2c_size_16_color_FFFFFF_t_70 13][]

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2h6YXVfaXRkb2c_size_16_color_FFFFFF_t_70 14][]

下一步

![2019122621060481.png][]

下一步，finish

建立成功之后会自动打开各个子模块

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2h6YXVfaXRkb2c_size_16_color_FFFFFF_t_70 15][]

在spring-itdog字模块中引入其他依赖

compile(project(":spring-context"))

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2h6YXVfaXRkb2c_size_16_color_FFFFFF_t_70 16][]

新建扫描类

package com.hzau;
    
    import org.springframework.context.annotation.ComponentScan;
    
    /**
     * @ClassName MyCompentScan
     * @Description TODO
     * @Author yueyiming
     * @Date 2020/1/2 12:15
     * @Version 1.0
     * https://blog.csdn.net/hzau_itdog
     **/
    @ComponentScan(basePackages = "com.hzau.**")
    public class MyCompentScan {
    }

新建实体类

package com.hzau;
    
    import org.springframework.stereotype.Component;
    
    /**
     * @ClassName MyBean
     * @Description TODO
     * @Author yueyiming
     * @Date 2020/1/2 12:14
     * @Version 1.0
     * https://blog.csdn.net/hzau_itdog
     **/
    @Component
    public class MyBean {
    	public MyBean() {
    	}
    }

进行测试

package com.hzau;
    
    import org.springframework.context.annotation.AnnotationConfigApplicationContext;
    
    /**
     * @ClassName MyTest
     * @Description TODO
     * @Author yueyiming
     * @Date 2020/1/2 12:14
     * @Version 1.0
     * https://blog.csdn.net/hzau_itdog
     **/
    public class MyTest {
    	public static void main(String[] args) {
    		AnnotationConfigApplicationContext context = new AnnotationConfigApplicationContext(MyCompentScan.class);
    		MyBean bean = context.getBean(MyBean.class);
    		System.out.println(bean);
    	}
    }

结果如下：
