Spring源码本地环境搭建

- 日理万妓 2023-07-19 12:08 50阅读 0赞

### 拉取源码 ###

首先我们到GitHub上找到Spring项目：  
![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2NoZW5fY2hhbmd5aW5n_size_16_color_FFFFFF_t_70]

将版本切换到5.0.x，然后复制分支链接：[https://github.com/spring-projects/spring-framework.git][https_github.com_spring-projects_spring-framework.git]  
![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2NoZW5fY2hhbmd5aW5n_size_16_color_FFFFFF_t_70 1]

直接通过idea拉取项目或者使用命令拉取：

![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2NoZW5fY2hhbmd5aW5n_size_16_color_FFFFFF_t_70 3]

### 项目导入 ###

由于Spring 5之后都是采用Gradle构建的，所以导入项目前本地需要有Gradle环境。  
Gradle下载地址：[https://gradle.org/releases/][https_gradle.org_releases]

下载完成之后，解压并添加环境变量：  
![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2NoZW5fY2hhbmd5aW5n_size_16_color_FFFFFF_t_70 4]  
![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2NoZW5fY2hhbmd5aW5n_size_16_color_FFFFFF_t_70 5]  
配置好之后通过`gradle -v`命令查看gradle版本，如果显示了版本信息，说明配置生效了：  
![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2NoZW5fY2hhbmd5aW5n_size_16_color_FFFFFF_t_70 6]

通过Gradle导入：  
![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2NoZW5fY2hhbmd5aW5n_size_16_color_FFFFFF_t_70 7]

项目属性设置：  
![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2NoZW5fY2hhbmd5aW5n_size_16_color_FFFFFF_t_70 8]

导入之后等待项目构建完成，构建成功之后会看到下图所示：  
![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2NoZW5fY2hhbmd5aW5n_size_16_color_FFFFFF_t_70 9]  
如果中途构建出错，或者超时了，点击gradle视图中的刷新按钮，会自动重新构建：

### 编译 ###

先使用gradle进行build：  
![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2NoZW5fY2hhbmd5aW5n_size_16_color_FFFFFF_t_70 11]  
然后再对项目进行编译：  
![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2NoZW5fY2hhbmd5aW5n_size_16_color_FFFFFF_t_70 12]

### 填坑之旅 ###

1、`Kotlin: [Internal Error] java.lang.LinkageError`  
如果出现这个错可能是Kotlin版本太低或者idea版本太低导致的：  
![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2NoZW5fY2hhbmd5aW5n_size_16_color_FFFFFF_t_70 13]  
可以尝试升级Kotlin或者升级idea：  
![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2NoZW5fY2hhbmd5aW5n_size_16_color_FFFFFF_t_70 14]  
![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2NoZW5fY2hhbmd5aW5n_size_16_color_FFFFFF_t_70 15]  
GitHub上也有人遇到了这个问题：[https://github.com/spring-projects/spring-framework/issues/23354][https_github.com_spring-projects_spring-framework_issues_23354]  
![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2NoZW5fY2hhbmd5aW5n_size_16_color_FFFFFF_t_70 16]  
我的升级完`Kotlin`就不报这个错了。

2、Gradle build的过程中checkstyle校验不过  
出现这个问题我们可以把去掉checkstyle，首先找到项目根目录的`build.gradle`文件：  
![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2NoZW5fY2hhbmd5aW5n_size_16_color_FFFFFF_t_70 17]  
然后将下图所示的两处地方注释掉，然后重新build就可以了：  
![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2NoZW5fY2hhbmd5aW5n_size_16_color_FFFFFF_t_70 18]  
![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2NoZW5fY2hhbmd5aW5n_size_16_color_FFFFFF_t_70 19]  
3、Error:(43, 16) java: 找不到符号符号: 类 AnnotationCacheAspect位置: 类 org.springframework.cache.aspectj.AspectJCachingConfiguration  
![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2NoZW5fY2hhbmd5aW5n_size_16_color_FFFFFF_t_70 20]  
原因是因为`AnnotationCacheAspect`文件不是`class`而是`aspect`所以jdk识别不了无法编译。

我们需要安装`aspectj.jar`使用`Ajc`进行编译。

`aspectj.jar`下载地址：[https://www.eclipse.org/aspectj/downloads.php][https_www.eclipse.org_aspectj_downloads.php]  
![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2NoZW5fY2hhbmd5aW5n_size_16_color_FFFFFF_t_70 21]  
下载好之后，在此文件的同级目录执行`java -jar aspectj-1.9.4.jar`命令打开安装界面：  
![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2NoZW5fY2hhbmd5aW5n_size_16_color_FFFFFF_t_70 22]  
![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2NoZW5fY2hhbmd5aW5n_size_16_color_FFFFFF_t_70 23]  
选择jdk安装目录：  
![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2NoZW5fY2hhbmd5aW5n_size_16_color_FFFFFF_t_70 24]  
设置`aspectj`安装位置：  
![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2NoZW5fY2hhbmd5aW5n_size_16_color_FFFFFF_t_70 25]  
点击`install`开始安装：  
![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2NoZW5fY2hhbmd5aW5n_size_16_color_FFFFFF_t_70 26]  
对AspectJ项目添加Facets，File -> Project Structure：  
![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2NoZW5fY2hhbmd5aW5n_size_16_color_FFFFFF_t_70 27]  
选择你所需要添加的Module，点击ok：  
![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2NoZW5fY2hhbmd5aW5n_size_16_color_FFFFFF_t_70 28]  
添加好之后Apply确认：  
![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2NoZW5fY2hhbmd5aW5n_size_16_color_FFFFFF_t_70 29]  
修改编译器为`Ajc`：  
![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2NoZW5fY2hhbmd5aW5n_size_16_color_FFFFFF_t_70 30]  
找到`Java Compiler`，将`Use compiler`修改为`Ajc`并选择`Ajc`的路径，然后勾选中`Delegate to Javac`，它的作用是只编译添加了AspectJ的项目，其他则使用Jdk：  
![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2NoZW5fY2hhbmd5aW5n_size_16_color_FFFFFF_t_70 31]  
测试代码：

<?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="myTestBean" class="org.springframework.test.MyTestBean"/>
    </beans>

public class Test {
    	public static void main(String[] args) {
    		BeanFactory beanFactory = new XmlBeanFactory(new ClassPathResource("beanFactoryTest.xml"));
    		MyTestBean bean = (MyTestBean) beanFactory.getBean("myTestBean");
    		bean.outStr();
    	}
    }
    
    class MyTestBean {
    
    	public void outStr() {
    		System.out.println("myTestBean");
    	}
    }

运行，成功输出：

一波三折，Spring源码本地环境终于构建成功！
