Spring源码分析(一) -- 环境搭建

1. 环境搭建

• 第一步搭建项目，根据下面项目详情的内容先把project建好，IDEA如何搭建Spring项目，这个靠自己了
• 第二步源码下载，在 Spring源码下载 下载对应版本的Spring源码，本文基于4.3.11.RELEASE版本
• 第三部导入源码，如何导入看这篇Intellij idea关联jar包和源码

2. 项目详情

• Applicaton.java

public class Application {
    public static void main(String[] args) {
        ClassPathXmlApplicationContext context = new ClassPathXmlApplicationContext("classpath:application.xml");
        MessageService messageService = (MessageService) context.getBean("messageService");
        System.out.println(messageService.getMessage());
    }
}

• MessageService.java

public interface MessageService {
    String getMessage();
}

• MessageServiceImpl.java

public class MessageServiceImpl implements MessageService {
    public String getMessage() {
        return "hello world";
    }
}

• application.xml

<?xml version="1.0" encoding="UTF-8" ?>
<beans xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xmlns="http://www.springframework.org/schema/beans"
       xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd" default-autowire="byName">

    <bean id="messageService" class="com.ktcatv.springmvc.service.impl.MessageServiceImpl"/>
</beans>

• 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">
