1.編譯spring源碼

本文是作者原創,版權歸作者所有.若要轉載,請注明出處

下載spring源碼,本文用的是版本如下:

springframework 5.1.x,   IDE工具idea 2019.2.3    JAVA版本 jdk1.8.0_171    構建工具gradle-4.9

1.下載springframework 5.1.x源碼

 

 2.解壓下載的壓縮包,在已有工程中導入該項目

 

 3.選擇該項目路徑

 

 4.選擇gradle導入

 

5.等待它自己構建

 

 6.編譯完,有個彈框出現,點擊ok

 

 7.如圖,設置gradle配置

 

 8.先編譯spring-core模塊

 

 9.編譯成功

 

 我們可以看到,多了存放字節碼文件的build文件夾

 

 10.編譯spring-oxm模塊,和上面一樣

 

 

 

 11.忽略spring-aspects模塊

 

 12.編譯整個spring模塊

 

 13.放開spring-aspects模塊,並編譯

 

 

 14.新建一個測試模塊,測試spring是否編譯成功

 

 

 

 

 

 

 

 

 點擊,右上角的ok

 

 加上以下代碼

//spring core
    compile(project(":spring-context"))
    //spring 對web的支持
    compile(project(":spring-webmvc"))
    //連接池
    compile(project(":spring-jdbc"))
    //mybatis core
    compile group: 'org.mybatis', name: 'mybatis', version: '3.5.0'

    //源碼 spring mybaits的插件包
    compile group: 'org.mybatis', name: 'mybatis-spring', version: '2.0.0'

    //db
    compile group: 'mysql', name: 'mysql-connector-java', version: '6.0.6'

    //tomcat 容器
    compile group: 'org.apache.tomcat.embed', name: 'tomcat-embed-core', version: '8.5.5'
    // jsp
    compile group: 'org.apache.tomcat.embed', name: 'tomcat-embed-jasper', version: '8.5.5'
    // https://mvnrepository.com/artifact/com.alibaba/fastjson
    compile group: 'com.alibaba', name: 'fastjson', version: '1.2.50'
    // https://mvnrepository.com/artifact/org.aspectj/aspectjweaver
    compile group: 'org.aspectj', name: 'aspectjweaver', version: '1.9.0'

最后build.gradle文件內容如下

plugins {
    id 'java'
}

group 'org.springframework'
version '5.1.10.BUILD-SNAPSHOT'

sourceCompatibility = 1.8

repositories {
    mavenCentral()
}

dependencies {
    testCompile group: 'junit', name: 'junit', version: '4.12'
    //spring core
    compile(project(":spring-context"))
    //spring 對web的支持
    compile(project(":spring-webmvc"))
    //連接池
    compile(project(":spring-jdbc"))
    //mybatis core
    compile group: 'org.mybatis', name: 'mybatis', version: '3.5.0'
    //源碼 spring mybaits的插件包
    compile group: 'org.mybatis', name: 'mybatis-spring', version: '2.0.0'
    //db
    compile group: 'mysql', name: 'mysql-connector-java', version: '6.0.6'
    //tomcat 容器
    compile group: 'org.apache.tomcat.embed', name: 'tomcat-embed-core', version: '8.5.5'
    // jsp
    compile group: 'org.apache.tomcat.embed', name: 'tomcat-embed-jasper', version: '8.5.5'
    // https://mvnrepository.com/artifact/com.alibaba/fastjson
    compile group: 'com.alibaba', name: 'fastjson', version: '1.2.50'
    // https://mvnrepository.com/artifact/org.aspectj/aspectjweaver
    compile group: 'org.aspectj', name: 'aspectjweaver', version: '1.9.0'
}

15.編寫demo

package demo01;

import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;


public class HelloSpring {

    private String input_str = null;

    public String getMyStr() {
        return this.input_str;
    }

    public void setMyStr(String strParam) {
        this.input_str = strParam;
    }

    public void Print() {
        System.out.println("Hello," + this.getMyStr());
    }

    public static void main(String[] args) {
        ApplicationContext context = new ClassPathXmlApplicationContext("applicationContext.xml");
        HelloSpring helloSpring = (HelloSpring) context.getBean("myFirstSpringDemo");
        helloSpring.Print();
        

    }

}

xml配置

<?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
        https://www.springframework.org/schema/beans/spring-beans.xsd"
    default-autowire="byType">

    <bean id="myFirstSpringDemo" class="demo01.HelloSpring">
        <property name="myStr">
            <value>I am Spring</value>
        </property>
    </bean>
</beans>

 

 

16.運行,報錯

 

 

可以看到錯誤信息提示我們在spring-context里找不到類,我們重新運行一下這個模塊的所有java下的test文件

 

 其他的問題也是一樣的處理方式,全部處理完

 

繼續運行demo

 

 好,編譯成功了,可以寫注釋了

 

 至此,我們的spring源碼編譯成功.下面我會繼續更新spring相關的應用和源碼博客,歡迎大家繼續關注,可以的話隨手點個贊吧,謝謝大家
