Spring Framework

History

Chris Beams b3ff9be78f M1 cut of environment, profiles and property work (SPR-7508) Decomposed Environment interface into PropertySources, PropertyResolver objects Environment interface and implementations are still present, but simpler. PropertySources container aggregates PropertySource objects; PropertyResolver provides search, conversion, placeholder replacement. Single implementation for now is PropertySourcesPlaceholderResolver Renamed EnvironmentAwarePropertyPlaceholderConfigurer to PropertySourcesPlaceholderConfigurer <context:property-placeholder/> now registers PSPC by default, else PPC if systemPropertiesMode* settings are involved Refined configuration and behavior of default profiles See Environment interface Javadoc for details Added Portlet implementations of relevant interfaces: * DefaultPortletEnvironment * PortletConfigPropertySource, PortletContextPropertySource * Integrated each appropriately throughout Portlet app contexts Added protected 'createEnvironment()' method to AbstractApplicationContext Subclasses can override at will to supply a custom Environment implementation. In practice throughout the framework, this is how Web- and Portlet-related ApplicationContexts override use of the DefaultEnvironment and swap in DefaultWebEnvironment or DefaultPortletEnvironment as appropriate. Introduced "stub-and-replace" behavior for Servlet- and Portlet-based PropertySource implementations Allows for early registration and ordering of the stub, then replacement with actual backing object at refresh() time. Added AbstractApplicationContext.initPropertySources() method to support stub-and-replace behavior. Called from within existing prepareRefresh() method so as to avoid impact with ApplicationContext implementations that copy and modify AAC's refresh() method (e.g.: Spring DM). Added methods to WebApplicationContextUtils and PortletApplicationContextUtils to support stub-and-replace behavior Added comprehensive Javadoc for all new or modified types and members Added XSD documentation for all new or modified elements and attributes Including nested <beans>, <beans profile="..."/>, and changes for certain attributes type from xsd:IDREF to xsd:string Improved fix for detecting non-file based Resources in PropertiesLoaderSupport (SPR-7547, SPR-7552) Technically unrelated to environment work, but grouped in with this changeset for convenience. Deprecated (removed) context:property-placeholder 'system-properties-mode' attribute from spring-context-3.1.xsd Functionality is preserved for those using schemas up to and including spring-context-3.0. For 3.1, system-properties-mode is no longer supported as it conflicts with the idea of managing a set of property sources within the context's Environment object. See Javadoc in PropertyPlaceholderConfigurer, AbstractPropertyPlaceholderConfigurer and PropertySourcesPlaceholderConfigurer for details. Introduced CollectionUtils.toArray(Enumeration<E>, A[]) Work items remaining for 3.1 M2: Consider repackaging PropertySource* types; eliminate internal use of SystemPropertyUtils and deprecate Further work on composition of Environment interface; consider repurposing existing PlaceholderResolver interface to obviate need for resolve[Required]Placeholder() methods currently in Environment. Ensure configurability of placeholder prefix, suffix, and value separator when working against an AbstractPropertyResolver Add JNDI-based Environment / PropertySource implementatinos Consider support for @Profile at the @Bean level Provide consistent logging for the entire property resolution lifecycle; consider issuing all such messages against a dedicated logger with a single category. Add reference documentation to cover the featureset.		14 years ago
