Spring MVC - Environment Setup

This chapter will guide you on how to prepare a development environment to start your work with Spring Framework. It will also teach you how to set up JDK, Maven and Ecppse on your machine before you set up Spring Framework −

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 instalpng 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:jdk-11.0.11, you would have to put the following pne in your C:autoexec.bat file.

set PATH=C:jdk-11.0.11;%PATH% 
set JAVA_HOME=C:jdk-11.0.11 

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

On Unix (Solaris, Linux, etc.), if the SDK is installed in /usr/local/jdk-11.0.11 and you use the C shell, you will have to put the following into your .cshrc file.

setenv PATH /usr/local/jdk-11.0.11/bin:$PATH 
setenv JAVA_HOME /usr/local/jdk-11.0.11

Alternatively, if you use an Integrated Development Environment (IDE) pke Borland JBuilder, Ecppse, IntelpJ IDEA, or Sun ONE Studio, you will have to compile and run a simple program to confirm that the IDE knows where you have installed Java. Otherwise, you will have to carry out a proper setup as given in the document of the IDE.

Setup Ecppse IDE

All the examples in this tutorial have been written using Ecppse IDE. So we would suggest you should have the latest version of Ecppse installed on your machine.

To install Ecppse IDE, download the latest Ecppse binaries from www.ecppse.org/downloads. Once you download the installation, unpack the binary distribution into a convenient location. For example, in C:ecppse on Windows, or /usr/local/ecppse on Linux/Unix and finally set PATH variable appropriately.

Ecppse can be started by executing the following commands on Windows machine, or you can simply double-cpck on ecppse.exe

%C:ecppseecppse.exe 

Ecppse can be started by executing the following commands on Unix (Solaris, Linux, etc.) machine −

$/usr/local/ecppse/ecppse

After a successful startup, if everything is fine then it should display the following result −

Install Apache Common Logging API

You can download the latest version of Apache Commons Logging API from https://commons.apache.org/logging/. Once you have downloaded the installation, unpack the binary distribution into a convenient location.

For example – C:commons-logging-1.1.1 on windows, or /usr/local/commons-logging1.1.1 on Linux/Unix. This directory will have the following jar files and other supporting documents, etc.

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

Setup Spring Framework Libraries

Now if everything is fine, then we can proceed to setup the Spring Framework. Following are the steps to download and install the framework on the machine.

Make a choice whether you want to install Spring on Windows or UNIX and then proceed to the next step to download .zip file for windows and .tz file for Unix.

Download the latest version of Spring framework binaries from https://repo.spring.io/release/org/springframework/spring.

We have downloaded the spring-5.3.14-dist.zip on the Windows Machine and when we unzip the downloaded file, it will give out the directory structure inside – E:spring as follows.

You will find all the Spring pbraries in the directory E:springpbs. Make sure you set your CLASSPATH variable on this directory properly; otherwise, we will face a problem while running the apppcation. If we use Ecppse, then it is not required to set the CLASSPATH because all the setting will be done through Ecppse.

Once you are done with this last step, you are ready to proceed for your first Spring Example, which you will see in the next chapter.
