Class EnvironmentAwareModuleOptionsMetadataResolver

java.lang.Object

org.springframework.xd.module.options.EnvironmentAwareModuleOptionsMetadataResolver

All Implemented Interfaces:

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

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

A decorator around another ModuleOptionsMetadataResolver that will provide default values for module options using the environment.

Each module gets its own Environment, populated with values in the following order:

• System properties and environment variables
• Values in a properties file found at $XD_MODULE_CONFIG_LOCATION/<type>/<module>/<module>.properties. Mappings in this file shall not use the fully qualified form, but rather the simple form <optionname>=<optionvalue>
• Values in a yml file found at $XD_MODULE_CONFIG_LOCATION/$XD_MODULE_CONFIG_NAME. Mappings in this file use the fully qualified form (see below)

For each option <optionname> of a module (of type <type> and name <modulename>), this resolver will try to read a default from <type>.<modulename>.<optionname>.
