A step by step guide to create a HelloWorld java application using Spring framework.
\n<\/p>\n

Generate project structure with Maven<\/h1>\n
mvn archetype:generate -DgroupId=net.qstation.springapp -DartifactId=HelloWorld -DarchetypeArtifactId=maven-archetype-quickstart -DinteractiveMode=false<\/pre>\n
Add Spring dependency<\/h1>\n
In pom.xml<\/strong>, add<\/p>\n

Create the bean<\/h1>\n
