Spring Boot CLI - Environment Setup


Spring is a Java-based framework; hence, we need to set up JDK first. Following are the steps needed to setup Spring Boot CLI along with JDK installation.

Step 1 - Setup Java Development Kit (JDK)

You can download the latest version of SDK from Oracle's Java site − Java SE Downloads. You will find instructions for installing JDK in downloaded files, follow the given instructions to install and configure the setup. Finally set PATH and JAVA_HOME environment variables to refer to the directory that contains java and javac, typically java_install_dir/bin and java_install_dir respectively.

If you are running Windows and have installed the JDK in C:\jdk1.6.0_15, you would have to put the following line in your C:\autoexec.bat file −

set PATH=C:\jdk1.6.0_15\bin;%PATH% 
set JAVA_HOME=C:\jdk1.6.0_15 

Alternatively, on Windows NT/2000/XP, you will have to right-click on My Computer, select Properties → Advanced → Environment Variables. Then, you will have to update the PATH value and click the OK button.

On Unix (Solaris, Linux, etc.), if the SDK is installed in /usr/local/jdk1.6.0_15 and you use the C shell, you will have to put the following into your .cshrc file −

setenv PATH /usr/local/jdk1.6.0_15/bin:$PATH 
setenv JAVA_HOME /usr/local/jdk1.6.0_15 

Step 2 - Install Spring Boot CLI

You can download the latest version of Spring Boot CLI API as ZIP archive from https://repo.spring.io/release/org/springframework/boot/spring-boot-cli/. Once you download the installation, unpack the zip distribution into a convenient location. For example, in E:\Test\spring-1.5.8.RELEASE on Windows, or /usr/local/spring-1.5.8.RELEASE on Linux/Unix.

Make sure you set your CLASSPATH variable on this directory properly otherwise you will face a problem while running your application.

Or set the path in command prompt temporarily to run the spring boot application as shown below −

E:/Test/> set path=E:\Test\spring-1.5.8.RELEASE\bin;%PATH%

Step 3 - Verify installation

Run the following command on command prompt to verify the installation −

E:/Test/> spring --version

It should print the following output confirming the successful installation −

Spring CLI v1.5.8.RELEASE
