corsexample

This demonstrates the problem with Grails due to spring-projects/spring-boot#6180. We have a following bean:

corsexample/src/main/groovy/corsmapping/MyCorsConfiguration.groovy

Lines 1 to 9 in 1b2570c

	package corsmapping
	import org.springframework.boot.context.properties.ConfigurationProperties
	@ConfigurationProperties(prefix = "grails.cors")
	class MyCorsConfiguration {
	Map<String, Map<String, List<String>>> mappings
	}

It should correctly bind the values to field mappings from the following YAML configurations as ['/words/googleOnly':['allowedOrigins': ['https://www.google.com']]] but in actual it is bound as: ['/words/googleOnly':['allowedOrigins[0]': 'https://www.google.com']]:

corsexample/grails-app/conf/application.yml

Lines 48 to 62 in 1b2570c

	grails:
	cors:
	enabled: true
	allowedHeaders:
	- Content-Type
	mappings:
	'[/word/googleOnly]':
	allowedOrigins:
	- https://www.google.com
	'[/word/stackoverflowOnly]':
	allowedOrigins:
	- https://stackoverflow.com
	'[/word/anywhere]':
	allowedOrigins:
	- '*'

Testing

• Run the Grails application using command ./gradlew bootRun.
• The following assertion in Bootstrap.groovy is failing:

corsexample/grails-app/init/corsmapping/BootStrap.groovy

Lines 1 to 10 in 1b2570c

	package corsmapping
	class BootStrap {
	MyCorsConfiguration myCorsConfiguration
	def init = { servletContext ->
	assert myCorsConfiguration.mappings.size() == 3
	assert myCorsConfiguration.mappings['/word/googleOnly']['allowedOrigins']
	}
