Summary: ConfigProperty support for maps Key: DELTASPIKE-1441 URL: https://issues.apache.org/jira/browse/DELTASPIKE-1441 Project: DeltaSpike Issue Type: Wish Security Level: public (Regular issues) Reporter: Andrew Marinchuk Let's assume that we have the following configuration:{code}my.param.a=1 my.param.b=2 my.param.c=3 ...{code} And we want to load all the {{my.param.*}} parameters into the {{Map<String, Integer>}}. With the current configuration api there two ways to load such config: # add parameter {{my.param.all=a,b,c,...}} with complete list of {{my.param.*}} parameters, add an {{@Inject}}'ed {{List<String>}} field with {{@ConfigProperty}} annotation to read this parameter and then fill the map values by reading value by each of the provided keys. # iterate through ConfigResolver.getAllProperties() by code like [filterPropsByPrefix function|https://issues.apache.org/jira/browse/DELTASPIKE-1212?focusedCommentId=16986128&page=com.atlassian.jira.plugin.system.issuetabpanels%3Acomment-tabpanel#comment-16986128] and fill the Map with it But I think that loading such config shouldn't be a user problem, library should be capable of loading it. Of course, user can introduce the {{@ApplicationScoped}} bean which will inherits the {{org.apache.deltaspike.core.spi.config.BaseConfigPropertyProducer}} and introduce the {{@Producer}} methods for {{Map<String, ?>}} analog for producers introduced in org.apache.deltaspike.core.impl.config.DefaultConfigPropertyProducer. But it should be a library code. Another use case which should be covered is loading Map<String, Intf> where Intf - interface with {{@Configuration}} annotation, i.e.: {code}datasources.one.url=jdbc://... datasources.one.user=myuser datasources.one.password=pass datasources.two.url=jdbc://.... datasources.two.user=myuser2 datasources.two.password=pass2 ...{code} Currently we use code from [this comment|https://issues.apache.org/jira/browse/DELTASPIKE-1212?focusedCommentId=16986128&page=com.atlassian.jira.plugin.system.issuetabpanels%3Acomment-tabpanel#comment-16986128] to load such configuration, but it could be much simpler if deltaspike had ConfigProperty support for maps with ability to use @Configuration interfaces as values. -- This message was sent by Atlassian Jira (v8.3.4#803005)
