60. Developing application with the Groovy beans DSL
Spring Framework 4.0 has native support for a beans{}
“DSL” (borrowed from Grails), and you can embed bean definitions in your Groovy application scripts using the same format. This is sometimes a good way to include external features like middleware declarations. For example:
_@Configuration_ class Application implements CommandLineRunner { _@Autowired_ SharedService service _@Override_ void run(String... args) { println service.message } } import my.company.SharedService beans { service(SharedService) { message = "Hello World" } }
You can mix class declarations with beans{}
in the same file as long as they stay at the top level, or you can put the beans DSL in a separate file if you prefer.
