Introduces a new API key interface that allows users to customize how
API keys are provided and managed in their Spring AI applications. This
change improves security and flexibility by:
- Adding core ApiKey interface and SimpleApiKey implementation
- Adding builder pattern for OpenAiApi creation
- Deprecating public constructors in favor of builder API (since 1.0.0.M6)
- Added docs
The new system enables users to implement their own key management
strategies while maintaining backward compatibility with property-based
configuration.
Introduce a utility class `LoggingMarkers` providing an SLF4J marker for tagging log entries with Personally Identifiable Information (PII). Update `BeanOutputConverter` to use the `PII_MARKER` in error logs for invalid JSON conversions. Enhance tests to verify PII marker usage in logging.
- Set Java version dynamically and configure Kotlin compiler
- Updated Maven configurations to dynamically reference the Java version using `${java.version}`. Added Kotlin compiler settings, including `jvmTarget` alignment with Java version and enabling `javaParameters`. This ensures consistency and better compatibility across builds.
- Fix log assertion in BeanOutputConverterTest to use Java 17
- Updated the test to assert log size explicitly before accessing the first log entry. This ensures the test is more robust and avoids potential issues with accessing logs unexpectedly.
- Use placeholders in logger.error to prevent string concatenation.
- Replaced string concatenation with a placeholder in the logger.error call to improve performance and maintain consistency with logging best practices. This helps avoid unnecessary overhead when logging is disabled.
- Update logging markers and improve data classification
- Replaced `PII_MARKER` with `SENSITIVE_DATA_MARKER`. Introduced `RESTRICTED_DATA_MARKER`, `REGULATED_DATA_MARKER` and `PUBLIC_DATA_MARKER`
- Updated associated logging logic and tests to reflect these changes.
- Fix punctuation in Javadoc comments for LoggingMarkers.
- Added missing periods to improve consistency and clarity in the Javadoc comments. This change ensures proper formatting and adheres to standard writing conventions.

* Introduced ToolCallingManager to manage the tool calling activities for resolving and executing tools. A default implementation is provided. It can be used to handle explicit tool execution on the client-side, superseding the previous FunctionCallingHelper class. It’s ready to be instrumented via Micrometer, and support exception handling when tool calls fail.
* Introduced ToolCallExceptionConverter to handle exceptions in tool calling, and provided a default implementation propagating the error message to the chat morel.
* Introduced ToolCallbackResolver to resolve ToolCallback instances. A default implementation is provided (DelegatingToolCallbackResolver), capable of delegating the resolution to a series of resolvers, including static resolution (StaticToolCallbackResolver) and dynamic resolution from the Spring context (SpringBeanToolCallbackResolver).
* Improved configuration in ToolCallingChatOptions to enable/disable the tool execution within a ChatModel (superseding the previous proxyToolCalls option).
* Added unit and integration tests to cover all the new use cases and existing functionality which was not covered by autotests (tool resolution from Spring context).
* Deprecated FunctionCallbackResolver, AbstractToolCallSupport, and FunctionCallingHelper.

- Remove model specific Usage implementations
- Add `Object getNativeUsage()` to Usage interface
- This will allow the model specific Usage data to be returned
- At the client side, client needs to cast the return type of `getNativeUsage` into the corresponding Usage returned by the model API
- Rename `generationTokens` to `completionTokens`
- Since `completion` token name is more common among the models, renaming generation tokens into completion tokens
- Maintain JSON deserialization compatibility for legacy `generationTokens` field
- Remove deprecated Long-based constructors to avoid API ambiguity
- Change the prompt, completion and total token return types from Long to Integer
- This is a breaking change that requires updating all constructor calls
- Integer is sufficient for token counts and aligns better with most model APIs
- Use DefaultUsage for most of the model specific usage handling
- When initializing set the native usage to the model specific usage type
- Ensure immutability by making all fields final and removing setters
- Add comprehensive test coverage for all functionality including edge cases
Resolves#1407
* Enhanced support for functions as tools via FunctionToolCallback (deprecating the existing FunctionInvokingFunctionCallback).
* Aligned JSON Schema generation and parsing logic between function-based and method-based tools.
* Deprecated previous client-side function calling APIs.

Add string-based filter deletion alongside the Filter.Expression-based deletion
for vector stores. This provides a more convenient API for simple filter cases
while maintaining the full flexibility of expression-based filtering.
Key changes:
- Add delete(Filter.Expression) and delete(String) methods to VectorStore
- Add default string filter implementation in VectorStore interface
- Implement filter deletion in Chroma/Elasticsearch/PgVector stores
- Add integration tests for both filter APIs across implementations
This extends vector store deletion capabilities while maintaining consistent
behavior across implementations.
* Defined new APIs consolidating the “tool” naming as opposed to the current “function”, aligning with the industry and solving the confusion between “function tool” and “Java Function”: ToolCallback and ToolCallingChatOptions. They extend the current ones to ensure backward compatibility, but FunctionCallback and FunctionCallingOptions can be considered deprecated.
* Enhanced support for methods as tools, introducing support for declarative Tool-annotated methods via MethodToolCallback and MethodToolCallbackProvider (deprecating the existing MethodInvokingFunctionCallback).
* Improved tool execution logic with granular support for returning the result directly to the client and exception handling.
* Improved JSON Schema generation and parsing logic, consolidating the usage of the victools/jsonschema-generator library and dropping the non-maintained Jackson JSON Schema Module. This makes it possible to use tools with input lists/arrays, which the latter library was not supporting.
* Extended ChatClient API with new methods tools() and toolCallbacks(). The existing functions() methods can be considered deprecated.

Moving BatchingStrategy configuration from individual vector store implementations
to the base AbstractVectorStoreBuilder to reduce code duplication and provide consistent
batching behavior across all vector stores.
The default TokenCountBatchingStrategy is now set in the base builder class.
* Remove use of Document.getContext method from spring-ai-core, use getText
* Remove deprecated ChatOptionsBuilder class
* Remove deprecated FunctionCallingOptionsBuilder class
Add backwards compatibility methods from FunctionCallingOptionsBuilder
to the Builder interface in FunctionCallingOptions. This allows users
to gradually migrate from the old builder style (with* methods) to the
new style while maintaining the same functionality.
Each deprecated method is marked for removal in 1.0.0-M5 and includes
proper Javadoc directing users to the new method names. The methods
are implemented as default methods that delegate to their new
counterparts.
This change streamlines the builder implementation by removing generics
that was complicating the implementation and providing hard to
debug checkstyle warnings.
It adopts a simpler, more direct builder pattern. Key changes:
- Remove generic type parameters from builder interfaces
- Switch to concrete builder implementations with direct field access
- Make all collection getters return unmodifiable views
- Ensure proper copy semantics in builders and options
- Add comprehensive test coverage for builder behavior
- Remove references of embedding from Document
- Update the javadoc for Document#score to reflect the embedding of either text/media instead of Document embedding
Fixes: #1913
Issue: https://github.com/spring-projects/spring-ai/issues/1913
- Add lineSeparator field to ExtractedTextFormatter with configurable override
- Update deleteTopTextLines and deleteBottomTextLines methods to use custom separator
- Mark old methods as deprecated in favor of new ones with separator parameter
- Update PDF test to use explicit line separator for Windows compatibility
* Introduce CompressionQueryTransformer and RewriteQueryTransformer in the Pre-Retrieval Module.
* Extend Query with conversation history and context.
* Remove QueryRouter sub-module. New design will be considered in the next milestone.
* Update RetrievalAugmentationAdvisor accordingly.
* Add initial documentation for Modular RAG, and establish dedicated page for RAG content.

This commit refactors the builder pattern implementation across all VectorStore
implementations to make the EmbeddingModel a required constructor parameter
rather than an optional builder method. Key changes include:
- Move embeddingModel from being a builder method to a required constructor parameter
- Make embeddingModel final in AbstractVectorStoreBuilder
- Remove redundant validate() methods since EmbeddingModel validation now happens
in constructor
- Update all VectorStore builder instantiations to pass EmbeddingModel in builder
creation
- Add @Nullable annotations to appropriate methods in VectorStore interface
This change improves the API design by:
1. Enforcing that EmbeddingModel is provided at builder creation time
2. Removing the possibility of forgotten EmbeddingModel configuration
3. Simplifying the builder implementation by moving validation to construction
4. Making the dependency on EmbeddingModel more explicit in the API
Breaking Changes:
- VectorStore builders must now be created with an EmbeddingModel parameter
- The embeddingModel() builder method has been removed from all implementations
