Class DefaultModuleOptionsMetadataResolver

java.lang.Object

org.springframework.xd.module.options.DefaultModuleOptionsMetadataResolver

All Implemented Interfaces:

org.springframework.beans.factory.Aware, org.springframework.context.ResourceLoaderAware, ModuleOptionsMetadataResolver

public class DefaultModuleOptionsMetadataResolver
extends java.lang.Object
implements ModuleOptionsMetadataResolver, org.springframework.context.ResourceLoaderAware

The default implementation of ModuleOptionsMetadataResolver that deals with simple modules and reads the companion .properties file sitting next to the module definition.

The following strategies will be applied in turn:

• look for a file named <modulename>.properties next to the module xml definition file
• if that file exists
  • look for an "options_class" property. If found, use a PojoModuleOptionsMetadata backed by that POJO class name
  • use a SimpleModuleOptionsMetadata backed by keys of the form options.<name>.description. Additionally, one can provide options.<name>.default and options.<name>.type properties.
• return an instance of PassthruModuleOptionsMetadata.
