From b7b2169ab4997232684ace458f3ede3a4fde02c8 Mon Sep 17 00:00:00 2001 From: Lukasz Lenart Date: Sun, 1 Feb 2026 10:24:35 +0100 Subject: [PATCH] feat(conversion): WW-4291 allow Spring bean names for type converters MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Implement two-phase processing for conversion properties to enable Spring bean name resolution in struts-conversion.properties files. The issue was a timing problem: type converters were processed during bootstrap phase before SpringObjectFactory was available. Now: - Early phase: process struts-default-conversion.properties (class names) - Late phase: process user properties when SpringObjectFactory is ready Changes: - Add UserConversionPropertiesProvider interface for late initialization - Add UserConversionPropertiesProcessor to trigger late phase processing - Split StrutsConversionPropertiesProcessor.init() into early/late phases - Register new beans in DefaultConfiguration and struts-beans.xml - Add alias in StrutsBeanSelectionProvider for dependency injection - Improve JavaDocs for BeanSelectionProvider classes Closes WW-4291 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude --- .../xwork2/config/BeanSelectionProvider.java | 20 ++- .../config/impl/DefaultConfiguration.java | 62 ++++---- .../org/apache/struts2/StrutsConstants.java | 1 + .../config/AbstractBeanSelectionProvider.java | 43 +++++- .../config/StrutsBeanSelectionProvider.java | 6 +- .../StrutsConversionPropertiesProcessor.java | 28 +++- .../UserConversionPropertiesProcessor.java | 55 +++++++ .../UserConversionPropertiesProvider.java | 38 +++++ core/src/main/resources/struts-beans.xml | 3 + ...rutsConversionPropertiesProcessorTest.java | 69 +++++++++ .../spring/SpringTypeConverterTest.java | 136 ++++++++++++++++++ 11 files changed, 418 insertions(+), 43 deletions(-) create mode 100644 core/src/main/java/org/apache/struts2/conversion/UserConversionPropertiesProcessor.java create mode 100644 core/src/main/java/org/apache/struts2/conversion/UserConversionPropertiesProvider.java create mode 100644 core/src/test/java/org/apache/struts2/conversion/StrutsConversionPropertiesProcessorTest.java create mode 100644 plugins/spring/src/test/java/org/apache/struts2/spring/SpringTypeConverterTest.java diff --git a/core/src/main/java/com/opensymphony/xwork2/config/BeanSelectionProvider.java b/core/src/main/java/com/opensymphony/xwork2/config/BeanSelectionProvider.java index 687943d364..a62500a14f 100644 --- a/core/src/main/java/com/opensymphony/xwork2/config/BeanSelectionProvider.java +++ b/core/src/main/java/com/opensymphony/xwork2/config/BeanSelectionProvider.java @@ -19,7 +19,25 @@ package com.opensymphony.xwork2.config; /** - * When implemented allows to alias already existing beans + * A {@link ConfigurationProvider} that selects and aliases bean implementations. + *

+ * This class provides the {@link #alias(Class, String, ContainerBuilder, Properties, Scope)} method + * which is used to select and register bean implementations based on configuration properties. + *

+ * + *

Bean Selection Process

+ *

+ * The {@code alias} method selects a bean implementation using the following process: + *

+ *
    + *
  1. Read the property value for the given key from the configuration properties
    2. + *
  2. If no property is set, use {@value #DEFAULT_BEAN_NAME} as the default bean name
    3. + *
  3. Check if a bean with that name already exists in the container: + *
      + *
    • If found, alias it to {@link Container#DEFAULT_NAME} making it the default
      • + *
    • If not found, try to load the property value as a fully qualified class name
      • + *
    + *
    4. + *
  4. If class loading succeeds, register the class as a factory for the interface type
    5. + *
  5. If class loading fails and the name is not the default, create a delegate factory + * that will resolve the bean through {@link ObjectFactory} at runtime. This allows + * Spring bean names to be used in configuration.
    6. + *
+ * + *

Usage Example

+ * 
+ * // In struts.properties or struts.xml:
+ * // struts.objectFactory = spring
+ * // struts.converter.collection = myCustomCollectionConverter
+ *
+ * // In a subclass:
+ * alias(ObjectFactory.class, StrutsConstants.STRUTS_OBJECTFACTORY, builder, props);
