io.helidon.security.CompositeProviderSelectionPolicy

All Implemented Interfaces:

ProviderSelectionPolicy

public class CompositeProviderSelectionPolicy
extends java.lang.Object
implements ProviderSelectionPolicy

A provider selection policy that supports composing multiple providers (current Authentication and Outbound) into a single virtual security provider.

Example configuration:

 security.provider-policy {
  type = "COMPOSITE"
  # explicit name of this policy (to be used when this is not the default or when we want to explicitly reference it)
  name = "composite"
  # whether this is the default provider or not (if not, must be explicitly defined by name, if yes, it is returned)
  default = true
  authentication: [
  {
      name = "first"
      flag = "REQUIRED"
  },
  {
      name = "second"
  }]
 outbound: [
  {
      name = "first"
  },
  {
      name = "second"
  }]
 }
