Spring Boot: read list from yaml using @Value or @ConfigurationProperties

Question

I want to read a list of hosts from a yaml file (application.yml), the file looks like this:

cors:
    hosts:
        allow: 
            - http://foo1/
             


        

Answer 1

I have been able to read list from properties like below way-

Properties-

cors.hosts.allow[0]=host-0
cors.hosts.allow[1]=host-1

Read property-

@ConfigurationProperties("cors.hosts")
public class ReadProperties {
    private List allow;

    public List getAllow() {
       return allow;
    }
    public void setAllow(List allow) {
        this.allow = allow;
    }
}
