Writing Groovy Scripts and Running Applications
Spring Cloud CLI has support for most of the Spring Cloud declarative
features, such as the @Enable* class of annotations. For example,
here is a fully functional Eureka server
app.groovy
@EnableEurekaServer
class Eureka {}
which you can run from the command line like this
$ spring run app.groovy
To include additional dependencies, often it suffices just to add the
appropriate feature-enabling annotation, e.g. @EnableConfigServer,
@EnableOAuth2Sso or @EnableEurekaClient. To manually include a
dependency you can use a @Grab with the special "Spring Boot" short
style artifact co-ordinates, i.e. with just the artifact ID (no need
for group or version information), e.g. to set up a client app to
listen on AMQP for management events from the Spring CLoud Bus:
app.groovy
@Grab('spring-cloud-starter-bus-amqp')
@RestController
class Service {
@RequestMapping('/')
def home() { [message: 'Hello'] }
}
