Java 包与文件夹结构?有什么区别 [英] Java Package Vs Folder-Structure? what is the difference

问题描述

我想知道 Eclipse IDE 中用于 Java EE 开发的文件夹结构和包之间有什么区别.

I would like to know What are the difference between folder-structure and package used in Eclipse IDE for Java EE development.

我们什么时候使用哪个，为什么?.

When do we use which one and why?.

应该怎么做

• 创建一个像src/com/utils这样的文件夹结构，然后在里面创建一个类
• 创建一个像 src.com.util 这样的包，然后在里面创建一个类

如果我以后必须编写 ant 脚本进行部署，哪个选项会更好且易于部署?

which option would be better and easy to deploy if i have to write a ant script later for deployment ?

如果我采用文件夹结构，部署是否会像将文件从开发复制到部署目标一样简单?

if i go for the folder-structure will the deployment is as easy as copying files from development to deployment target ?

推荐答案

如果你正确配置了东西.在 src 中添加文件夹，与从 File > 中添加包相同.新包.

If you configured stuffs correctly. Adding a folder inside src, is same as adding a package from File > New Package.

因此，这取决于您，无论您感觉如何——添加文件夹或创建包.此外，当您将东西放在 src 下时，包名称从子文件夹开始.所以，src/com/naishe/test 将是包 com.naishe.test.

So, it's up to you, whatever feels comfortable to you -- add a folder or create a package. Also, when you put stuffs under src the package name starts from subfolder. So, src/com/naishe/test will be package com.naishe.test.
