嘗試編譯最簡單的Spring程序：
Main.java

import org.springframework.beans.factory.BeanFactory;
import org.springframework.context.support.ClassPathXmlApplicationContext;
//下面的代碼沒用
public class Main {  
    private String who = null;  
    public static void main(String[] args) {  
        BeanFactory factory = new ClassPathXmlApplicationContext("applicationContext.xml");  
        HelloWorld hw1 = (HelloWorld)factory.getBean("hello");//map.get("hello")  
        System.out.println(hw1.getInfo());  
        System.out.println(hw1);  
    }  
}

命令行：

$javac -cp /path/of/spring-beans.jar:/path/of/spring-context-support.jar Main.jar

完整的：

javac  -cp /Users/apple/Desktop/springt/sp/spring-framework-5.0.5.RELEASE/libs/spring-beans-5.0.5.RELEASE.jar:/Users/apple/Desktop/springt/sp/spring-framework-5.0.5.RELEASE/libs/spring-context-support-5.0.5.RELEASE.jar Main.java

報錯：

Main.java:3: error: package org.springframework.context.support does not exist
import org.springframework.context.support.ClassPathXmlApplicationContext;
                                      ^
Main.java:12: error: cannot find symbol
    BeanFactory factory = new ClassPathXmlApplicationContext("applicationContext.xml");  

開始我以為自己哪里出錯了，但是解壓jar開發(fā)包發(fā)現(xiàn)：
org.springframework.beans.factory.BeanFactory 正常，但是
spring-context-support-5.0.5.RELEASE根本沒有context.support

$ pwd

為什么會出現(xiàn)這種情況？
我又重新下載了幾個早些版本的Spring jar包，同樣沒有相應(yīng)的目錄，我是哪里出錯了？
