Chapter 1 configuration of development environment under mac, Chapter 1 mac Development Environment

Mac is similar to Linux, but different from windows.

 

1. jdk

Built-in mac, no installation required.

View the installed jdk version:

How to open a command terminal: The mac command terminal is similar to Windows cmd and Linux Command Line terminal.

Method 1:

Finder> Application> utility> Terminal

Method 2:

Click "command + space ",

Enter "java-version" on the terminal ". View the information, just like Windows.

 

Note:

• "Command + space" is the shortcut key for opening the search tool in mac. This search tool is very good.
• It is worth noting that, in fact, the default mac Input Method for switching between Chinese and English shortcuts is also "command + space", which leads to a conflict of shortcut keys, resulting in one of them being unavailable, so you need to modify the shortcut keys, the method is as follows: System Preferences --> language and region --> keyboard preferences -->

Then click the shortcut key to modify it.

 

2. maven

Download it, decompress it, configure settings. xml, and configure private servers on mac. In windows, you also need to configure "local repository" in addition to private servers ".

Finally, configure the environment variables as follows:

If no. bash_profile exists, first "mkdir. bash_profile ".

Use "vi. bash_profile" to open the file and add the following two information.

• Article 1: Set the maven decompression directory

Finally, open the terminal --> enter "mvn-v" to check whether the installation is successful.

Note:

• Ls-a: Add-a to display the hidden files.
• The use of vi is the same as that of Linux.

 

3. git

Built-in mac, no installation required.

View the git version: Open the terminal and enter "git -- version" to check whether the version is successful.

Git usage: Simply enter the command on the terminal.

 

4. eclipse

Download, decompress, and configure settings. xml to eclipse.

Open "preferences": Unlike Windows, click Eclipse next to the Apple symbol --> click "preferences" ("preferences" in mac is "preferences" in windows ")

• ~ Is/Users/enniu1/

5. The installation of MySQL, navicat, and other software has not yet been conducted and will be recorded later.
