Spring AOP - Environment Setup


Advertisements


This chapter takes you through the process of setting up Spring AOP on Windows and Linux based systems. Spring AOP can be easily installed and integrated with your current Java environment and MAVEN by following a few simple steps without any complex setup procedures. User administration is required while installation.

System Requirements

JDK Java SE 2 JDK 1.5 or above
Memory 1 GB RAM (recommended)
Disk Space No minimum requirement
Operating System Version Windows XP or above, Linux

Let us now look at the steps to install Spring AOP.

Step 1: Verify your Java Installation

First of all, you need to have Java Software Development Kit (SDK) installed on your system. To verify this, execute any of the following two commands depending on the platform you are working on.

If the Java installation has been done properly, then it will display the current version and specification of your Java installation. A sample output is given in the following table.

Platform Command Sample Output
Windows

Open command console and type −

\>java -version

Java version "1.7.0_60"

Java (TM) SE Run Time Environment (build 1.7.0_60-b19)

Java Hotspot (TM) 64-bit Server VM (build 24.60-b09,mixed mode)

Linux

Open command terminal and type −

$java -version

java version "1.7.0_25"

Open JDK Runtime Environment (rhel-2.3.10.4.el6_4-x86_64)

Open JDK 64-Bit Server VM (build 23.7-b01, mixed mode)

We assume the readers of this tutorial have Java SDK version 1.7.0_60 installed on their system.

In case you do not have Java SDK, download its current version from https://www.oracle.com/technetwork/java/javase/downloads/index.html and have it installed.

Step 2: Set your Java Environment

Set the environment variable JAVA_HOME to point to the base directory location where Java is installed on your machine. For example,

Sr.No. Platform & Description
1

Windows

Set JAVA_HOME to C:\ProgramFiles\java\jdk1.7.0_60

2

Linux

Export JAVA_HOME = /usr/local/java-current

Append the full path of Java compiler location to the System Path.

Sr.No. Platform & Description
1

Windows

Append the String "C:\Program Files\Java\jdk1.7.0_60\bin" to the end of the system variable Path.

2

Linux

Export PATH = $PATH:$JAVA_HOME/bin/

Execute the command java -version from the command prompt as explained above.

Step 3: Download Maven Archive

Download Maven 3.3.3 from https://maven.apache.org/download.cgi

OS Archive Name
Windows apache-maven-3.3.3-bin.zip
Linux apache-maven-3.3.3-bin.tar.gz
Mac apache-maven-3.3.3-bin.tar.gz

Step 4: Extract the Maven Archive

Extract the archive, to the directory you wish to install Maven 3.3.3. The subdirectory apache-maven-3.3.3 will be created from the archive.

OS Location (can be different based on your installation)
Windows C:\Program Files\Apache Software Foundation\apache-maven-3.3.3
Linux /usr/local/apache-maven
Mac /usr/local/apache-maven

Step 5: Set Maven Environment Variables

Add M2_HOME, M2, MAVEN_OPTS to environment variables.

OS Output
Windows

Set the environment variables using system properties.

M2_HOME = C:\Program Files\Apache Software Foundation\apache-maven-3.3.3

M2 = %M2_HOME%\bin

MAVEN_OPTS = -Xms256m -Xmx512m

Linux Open command terminal and set environment variables.

export M2_HOME = /usr/local/apache-maven/apache-maven-3.3.3

export M2 = $M2_HOME/bin

export MAVEN_OPTS = -Xms256m -Xmx512m

Mac

Open command terminal and set environment variables.

export M2_HOME = /usr/local/apache-maven/apache-maven-3.3.3

export M2 = $M2_HOME/bin

export MAVEN_OPTS = -Xms256m -Xmx512m

Step 6: Add Maven Bin Directory Location to System Path

Now append M2 variable to System Path.

OS Output
Windows Append the string ;%M2% to the end of the system variable, Path.
Linux export PATH = $M2:$PATH
Mac export PATH = $M2:$PATH

Step 7: Verify Maven installation

Now open console, and execute the following mvn command.

OS Task Command
Windows Open Command Console c:\> mvn --version
Linux Open Command Terminal $ mvn --version
Mac Open Terminal machine:< joseph$ mvn --version

Finally, verify the output of the above commands, which should be something as follows −

OS Output
Windows

Apache Maven 3.3.3 (7994120775791599e205a5524ec3e0dfe41d4a06; 2015-04-22T17:27:37+05:30)

Step 8 - Set Up Eclipse IDE

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

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

Eclipse can be started by executing the following commands on Windows machine, or you can double-click on eclipse.exe

 %C:\eclipse\eclipse.exe

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

$/usr/local/eclipse/eclipse

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

Eclipse Home page

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