1. Developing Applications 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 by using the same format.
This is sometimes a good way to include external features like middleware declarations, as shown in the following example:
@Configuration(proxyBeanMethods = false)
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, if you prefer, you can put the beans DSL in a separate file.
