public class DefaultBeanSelectionProvider
extends AbstractBeanSelectionProvider

Selects the implementations of key framework extension points, using the loaded property constants. The implementations are selected from the container builder using the name defined in its associated property. The default implementation name will always be "struts".

The following is a list of the allowed extension points:

Type Property Scope Description

com.opensymphony.xwork2.util.TextParser struts.expression.parser singleton Used to parse expressions like ${foo.bar} or %{bar.foo} but it is up tp the TextParser's implementation what kind of opening char to use (#, $, %, etc)

Implementations are selected using the value of its associated property. That property is used to determine the implementation by:

  1. Trying to find an existing bean by that name in the container
  2. Trying to find a class by that name, then creating a new bean factory for it
  3. Creating a new delegation bean factory that delegates to the configured ObjectFactory at runtime

Finally, this class overrides certain properties if dev mode is enabled:
