Spring Framework源代码环境搭建

2024-11-11 技术教程

概要

本文介绍使用IntelliJ IDEA搭建Spring Framework源代码环境，用于源代码阅读与debug。

环境搭建1.下载源代码

访问Spring Framework在GitHub的地址，下载最新源代码。本人在下载时，版本号为5.2.2.BUILD-SNAPSHOT

https://github.com/spring-projects/spring-framework

2.根据说明导入IntelliJ IDEA

根据源代码文件中的IDEA导入说明进行操作，说明文件为源代码根目录的import-into-idea.md

Precompile `spring-oxm` with `./gradlew :spring-oxm:compileTestJava`Import into IntelliJ (File -> New -> Project from Existing Sources -> Navigate to directory -> Select build.gradle)When prompted exclude the `spring-aspects` module (or after the import via File-> Project Structure -> Modules)Code away1.需要预编译spring-oxm，通过控制台，进入到Spring Framework目录，运行命令gradlew :spring-oxm:compileTestJava。
注：Spring Framework是通过Gradle进行的编译打包，故需要提前安装Gradle2.导入至IDEA中，操作方法：File -> New -> Project from Existing Sources -> Navigate to directory -> Select build.gradle
3.排除spring-aspects模块，因IDEA的问题该模块不会被识别，如不排除则会提示编译错误。
操作方法：spring-aspects右键 -> Load/Unload modules -> 添加spring-aspects为Unloaded modules
测试DEMO在源代码项目目录下，本人直接创建了一个Maven测试项目，并创建了一个简单的Bean注册于获取的例子。pom.xml

<?xml version="1.0" encoding="UTF-8"?><project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd"> <modelVersion>4.0.0</modelVersion> <groupId>cn.daiwuliang</groupId> <artifactId>demo</artifactId> <version>1.0-SNAPSHOT</version> <name>demo</name>  <url>http://www.example.com</url> <properties> <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding> <maven.compiler.source>1.8</maven.compiler.source> <maven.compiler.target>1.8</maven.compiler.target> </properties> <dependencies> <dependency> <groupId>junit</groupId> <artifactId>junit</artifactId> <version>4.11</version> <scope>test</scope> </dependency>  <dependency> <groupId>commons-logging</groupId> <artifactId>commons-logging</artifactId> <version>1.2</version> </dependency> </dependencies> <build> <pluginManagement> <plugins>  <plugin> <artifactId>maven-clean-plugin</artifactId> <version>3.1.0</version> </plugin>  <plugin> <artifactId>maven-resources-plugin</artifactId> <version>3.0.2</version> </plugin> <plugin> <artifactId>maven-compiler-plugin</artifactId> <version>3.8.0</version> </plugin> <plugin> <artifactId>maven-surefire-plugin</artifactId> <version>2.22.1</version> </plugin> <plugin> <artifactId>maven-jar-plugin</artifactId> <version>3.0.2</version> </plugin> <plugin> <artifactId>maven-install-plugin</artifactId> <version>2.5.2</version> </plugin> <plugin> <artifactId>maven-deploy-plugin</artifactId> <version>2.8.2</version> </plugin>  <plugin> <artifactId>maven-site-plugin</artifactId> <version>3.7.1</version> </plugin> <plugin> <artifactId>maven-project-info-reports-plugin</artifactId> <version>3.0.0</version> </plugin> </plugins> </pluginManagement> </build></project>TestDemo

package demo.test;public class TestDemo { public String test(String str) { return String.format("ECHO: %s", str); }}App.java

package demo.test;import org.springframework.context.ApplicationContext;import org.springframework.context.support.FileSystemXmlApplicationContext;public class App { public static void main(String[] args) { String XMLPath = "D:\\spring-framework-master\\demo\\src\\main\\java\\demo\\test\\spring-config.xml"; ApplicationContext applicationContext = new FileSystemXmlApplicationContext(XMLPath); TestDemo td = (TestDemo) applicationContext.getBean("testDemo"); System.out.println(td.test("Hello World!!!")); }}spring-config.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 id="testDemo" class="demo.test.TestDemo"/></beans>运行问题Demo模块需要添加相应的spring模块的依赖，添加方式：File -> Project Structure -> Dependencies，目前Demo中仅实现了简单的例子，故只添加了如下几个模块：
spring-core中缺少commons-logging的依赖
虽然已经在demo的pom中添加了依赖，但仍旧报错，本人的解决办法为在spring-core的spring-core.gradle再添加一次，并重新构建

dependencies { ...... compile("commons-logging:commons-logging:1.2")}CoroutinesRegistrar中找不到变量CoroutinesUtils
CoroutinesUtils位于spring-core目录下的kotlin-coroutines中，看结构其为一个独立的模块，并且spring-core并未关联依赖。
找到kotlin-coroutines/build/libs/kotlin-coroutines-5.2.2.BUILD-SNAPSHOT.jar->右键Add as Library

至此，运行App中的main方法，得到以下结果:

Hello World!
