SpringBoot is one of the main projects of Spring community which takes opinionated view of production ready applications. It helps you getting up and running a production grade spring application. <\/p>\n
It comes with even a CLI to get you quick started with springboot. CLI stands for Command Line Interface which gives *spring* command using which the application could be run.<\/p>\n
This CLI allows you to create a groovy script called Spring script in Springboot documentation which could be run as a spring application using simple command <\/p>\n
A simple example of a Spring script could be as below: This script just by default imports few annotation classes(e.g. Controller,ResponseBody and RequestMApping above) and add annotations when run with CLI. In normal spring application without a springboot CLI but with springboot would require to add the imports for these.<\/p>\n Below are the annotations added itself by CLI. More, you can create FAT jars(A fat jar is simply a jar that contains all the required jars within single jar and hence can be run independently) using command below<\/p>\n This will create a excutable jar which could be run using following basic java command<\/p>\n Springboot CLI could be installed if using GVM by running following command:<\/p>\n gvm is independent of OS. Though if using MAC and using Homebrew, all you need to do to install the Spring Boot CLI is:<\/p>\n Note:If you don\u2019t see the formula, your installation of brew might be out-of-date. Just execute <\/p>\n and try again.<\/p>\n If you are on a Mac and using MacPorts, all you need to do to install the Spring Boot CLI is: <\/p>\n Least but not last, springboot CLI should not be used for production stuff and just for testing and hands on purpose.<\/p>\n Finally, springboot CLI is no way required or must to run a springboot rich spring application, it is just a hands on tool.<\/p>\n","protected":false},"excerpt":{"rendered":" SpringBoot is one of the main projects of Spring community which takes opinionated view of production ready applications.

\n@Grab annotation is used to add a starter pom. A starter pom is nothing but a collection of jars dependencies and plugins grouped together.
\nAdded above is the web starter which provides sensible defaults for a spring web applications.
\n@EnableAutoConfiguration enables default confiurations and best tries to configure the application by looking up in added jar files. For example if you have embedded a tomcat-embed.jar then it considers that you want to use tomcat.<\/p>\nspring jar test.jar file_name.groovy<\/code><\/p>\njava -jar jar_file<\/code><\/p>\ngvm install springboot<\/code><\/p>\n$ brew tap pivotal\/tap
