Second, the installation process

　　1. JDK

To install the JDK:

You can start the installation by double-clicking the Jdk-8u171-windows-x64.exe file. You can use the default configuration to continue clicking next until the installation is complete.

You can also manually specify the installation directory, for example, I install the JDK myself in the D:\JAVA\JDK1.8.0_171,JRE installation at D:\Java\jre1.8.0_171.

　　　　To configure environment variables:

　　　⑴ Right-click on the computer icon, then click on the menu item at the bottom of the menus, or open the Control Panel continuously-system and security-the system can also

⑵ Click Advanced System Settings-advanced-System Variables

⑶ the Java_path value of the new variable in the system variable is the installation root of the JDK. Example: D:\Java\jdk1.8.0_171

⑷. Continue to create a new variable CLASSPATH value of .;        %java_home%\lib; Note that the value of this variable begins with a period symbol and ends with a semicolon.

⑸ edit the path variable and add the string to the front ;%java_home%\bin;%java_home%\jre\bin; Note that there is no path variable that needs to be created manually.

　　　　Test:

　　　　　 Using the Win+r combination shortcut to open the Run tool, enter the cmd command into the DOS window, continue to enter the Java-version has the following output, that is, the installation is successful.

　　　　　　

　　2. Maven

　　　　Installation:

　　　　Unzip the downloaded file Apache-maven-3.5.3-bin.zip to the specified directory (here according to your needs). I was put in the E:\apache-maven-3.5.3, the directory has bin, Lib and other folders.

　　　　

　　　　Environment variable configuration:

　　　　Process and install the JDK, create a variable m2_path value of E:\apache-maven-3.5.3 . Find the variable path, add the string ;%m2_home%\bin;

　　　　

Test:

　　　　Open the DOS command window, the input mvn-v has the following output, that is, the installation is successful.

　　　　

　　　　Modify the Local warehouse location (this step is omitted if you do not want to modify the local warehouse location)

maven places the downloaded class library in a local directory (typically stored in the C: \ My document \.m2.\repository), and if you want to change the location of this directory, you need to modify the configuration of the Maven local repository.

1, create the local warehouse location, my location is (E:\Maven\repo)

2, locate the Conf folder in the directory where Maven is installed, locate the Settings.xml file in the folder, copy the Settings.xml file in E:\Maven, as shown in:

　　　　　　　　　　　　

3. Modify the Settings.xml file as shown in:

　　　　　　

4. Locate the Conf folder in the directory where MAVEN is installed, locate the Settings.xml file in the folder, and change the default warehouse location as shown: (Note the settings.xml in all two places to be modified)

　　　　　　

Based on this configuration, Maven will save the downloaded class library to E:/maven/repo.

5. DOS window input: mvn help:system

After executing the command, a number of files appear under E:/maven/repo, which are files that Maven downloads from the central repository to the local repository.

　　3. TOMCAT

　　　　Unzip it, my directory is E:\apache-tomcat-8.5.30

4. STS

　　　　Unzip the downloaded file, my directory is E:\sts-bundle\sts-3.9.4.RELEASE, open the tool

　　　Configure local Maven

　　　　

　　　　

　　　　

Configuring the Tomcat server
