TDD Kickstart with Spring 4.x + Maven 3.x + MongoDB 3.x - PART 1

I guess my TDD skills has slowly melted down as I was not actively programming more than six f*king months! I need a kickstart to refresh my laggy old brain and naggy Macbook Pro Yosemite OSX (upgrades needed).

What do you need?

• Maven 3.x
• MongoDB 3.x
• Java JDK 1.7.x
• Eclipse IDE Java EE Developer (mine is Luna with m2e plugin installed)

OK assuming you've all of these installed and working, let gets dirty (I mean hands).

What are the steps?

• Create a mongodb collection & document
• Create a java web project And Import to Eclipse IDE
• Add project dependencies: Spring core, Spring test, Spring data mongo etc...
• Write you TDD code. "Red -> Green -> Refactor" cycle.

A. Create a mongodb collection & document

1. Start your mongod: mongodb -dbpath <choose your db path i.e.: /usr/local/var/mongodb/data> &
2. Start your mongo shell, type: mongo --shell
3. In shell, create your db collection, type:  use <choose your db i.e.: demo>
4. In shell, create one entry, type: db.demo.insert({name: "hamid", socialSecurity: 1234567890})
5. In shell, verify your entry, type: db.demo.find()

B. Create java web project (please make sure you're connected to the internet)

1. In command line, navigate to your eclipse workspace folder. If there isn't existing, create one.
2. Create java web project (just hit enter on interactive prompt), type: mvn archetype:generate -DgroupId=<choose one i.e.: com.pointcut.demo> -DartifactId=<choose one i.e.: springmongo> -DarchetypeArtifactId=maven-archetype-webapp
3. On "BUILD SUCCESS" (after a long while), navigate to your project folder (i.e.: springmongo) to get your project eclipse ready, type: mvn eclipse:clean eclipse:eclipse
4. Import into eclipse IDE: Goto menu File->Import->Maven->Existing Maven Projects and locate your project in your workspace folder.
5. Make sure you project points to the right JDK runtime in Java Build Path: Right click on project name->Build Path->Configure Build Path...

C. Add project dependencies: Spring core, Spring test, Spring data mongo

1. Add project dependencies: Right click on project name->Maven->Add Dependency
2. In "Add Dependency" window, type "spring-core" in "Enter groupId, artifactId or sha1 prefix or pattern (*)" field
3. Choose related library from "Search Results" list choose "org.springframework spring-core"-> 4.0.2.RELEASE version
4. Repeat previous two (2) steps for spring-test (4.0.2.RELEASE), spring-context (4.0.2.RELEASE), spring-context-support (4.0.2.RELEASE), spring-beans (4.0.2.RELEASE), spring-data-mongodb (1.2.0.RELEASE), spring-beans (4.0.2.RELEASE), mongo-java-driver (2.9.1)
5. Update your maven project: Right click on project name ->Maven->Update Project...

Installation Guide

How to install? I love using command line if all possible. ok briefly this is what I did via command line, at least.

For Maven 3.x

1. Download the archive from here. In command line, wget <archive url address>
2. Unzip it. For my case at /usr/local. Depending on your archive (.zip or tar.gz) u may want to user unzip or tar zxvf in command line.
3. Set the home var and path. Update your .bash_profile (I use vi), scroll all the way down and insert the following lines: 

          export M2_HOME=/usr/local/<Maven Extracted Folder>
          export PATH=$PATH:$MAVEN_HOME/bin

For Mongo DB 3.x (recommend 64-bit)

1. Download the archive from here. Again, in command line wget <archive url address>
2. Unzip it. For my case at /usr/local. Depending on your archive (.zip or tar.gz) u may want to user unzip or tar zxvf in command line.
3. Set the home var and path. Update your .bash_profile (I use vi), scroll all the way down and insert the following:

          export MONGO_HOME=/usr/local/<Mongo Extracted Folder>
          export PATH=$PATH:$MONGO_HOME/bin

For Java JDK 1.7 here for Mac
