Spring Boot is a command-line tool for rapid prototyping with Spring to build. It allows you to run Groovy scripts, which means you can use the Java-like syntax, and not so much the template code.

Springboot-cli simple example
Run Groovy scripts
After completing the installation Spring Boot CLI, we try to use it to quickly build a Spring Boot application, the method is very simple, just do the following:
Step one: Create a Groovy script, hello.groovywhich reads as follows:
@RestController class ThisWillActuallyRun { @RequestMapping("/") String home() { "Hello World!" } }
Step 2: Use springthe command to run the Groovy script, as follows:
$ spring run hello.groovy Resolving dependencies............................................... *::::::::::::::* :::::::::::::::::::::::::: :::::::::::::::::::::::::::::::: :. *::::::::::::::::::::::::::::::::::::: :*: ::::::::::::::::::::::::::::::::::::::::::: *: .:::::::::::::::::::::::::::::::::::::::::: : ::::::::::::::::::::::::::::::::::::::::::. .: ::::::::::::::::::::::::::::::::::::::::: : :::::::::::::::::::::::::::::::::::::: *: :::::::::::::::::::::::::::::::::* : :::::::::::::::::::* : ::::::::::::::: * *: .:::::::::::: * .: :::::::::::. : : :::::::::: : .: :::::::::: :: .: .:::::::: ::: :* :::::::: ::: : :::::::: :::: :: ::::::: ::::: *: ::::::: *::::::: :: :::::::. ::::::::::: ::: :::::::::::::::::::::::* :::: .::: :::::::::* .:::::* : :::::::::::::::::::::::::::::::::::: . .::::::::::::::::::::::::::::::::::: :::::::::::::::::::::::::::::::: :::::::::::::::::::::::::: *::::::::::::::* 2018-04-04 18:11:20.571 INFO 70477 --- [ runner-0] o.s.boot.SpringApplication : Starting application on zhaiyongchaodeMacBook-Pro.local with PID 70477 (started by zhaiyongchao in /Users/zhaiyongchao/Downloads) 2018-04-04 18:11:20.574 INFO 70477 --- [ runner-0] o.s.boot.SpringApplication : No active profile set, falling back to default profiles: default 2018-04-04 18:11:20.732 INFO 70477 --- [ runner-0] ConfigServletWebServerApplicationContext : Refreshing org.springframework.boot.web.servlet.context.AnnotationConfigServletWebServerApplicationContext@3c3ad454: startup date [Wed Apr 04 18:11:20 CST 2018];

From the log, we can see a simple web application by Groovy script defines us build on the success, you can access localhost:8080to verify the above application interfaces provided by:
$ curl localhost:8080 Hello World!
Can be added in the command springconfiguration parameters, need to pay more attention to a--
$ spring run hello.groovy -- --server.port=9000
To set the JVM parameters, you can use JAVA_OPTSenvironment variables, such as:
$ JAVA_OPTS=-Xmx1024m spring run hello.groovy
Initialize a new project
Use initcommand to create a new project. Such as:
$ spring init --dependencies=web,data-jpa my-project
This command creates a named my-projectdirectory, which contains an in-based Mavenproject, and add to spring-boot-starter-weband spring-boot-starter-data-jpadependent.
You can use the --listtag to display all available dependencies.
$ spring init --list
Run spring help initcan see the specific instructions for use.
The following command creates a basis Gradleand java8packaging type warof project.
$ spring init --build=gradle --java-version=1.8 --dependencies=websocket --packaging=war sample-app.zip
Use Spring Shell
Spring Boot CLI built a shell, the implementation spring shellcan start. The shell supports ANSI color output and tabkey, if you want to perform native command, the command with !the prefix can be. More specific use, you can enter into the shell helpview.
