I am pleased to announce that Spring Batch 6.0.0-RC2 is now available from Maven Central!

What's new in Spring Batch 6.0.0-RC2?

This second release candidate introduces a long-awaited feature which is the use of contextual lambda expressions to configure batch artefacts. This new style of configuration provides a more concise and readable way to define item readers and writers.

For example, instead of using the traditional builder pattern like in the following snippet to define a delimited file reader:

var reader = new FlatFileItemReaderBuilder()
    .resource(...)
    .delimited…

This is a new blog post in the Road to GA series, this time updating everyone on the plans to integrate Spring gRPC with Spring Boot 4. The original plan was to move the autoconfiguration from Spring gRPC into Spring Boot in time for the 4.0 release. Unfortunately we haven't been able to find the time to merge that change, but the good news is that we have instead added support for Spring Boot 4 to the existing Spring gRPC project, and are planning a 1.0 release in the coming days. This arrangement will continue until the merge can finally happen, most likely in an early milestone of Spring…

I am pleased to announce that the second Spring for GraphQL 2.0 Release Candidate is now available.

The Spring AI ChatClient offers a fluent API for communicating with an AI model. The fluent API provides methods for building the constituent parts of a prompt that gets passed to the AI model as input.

Advisors are a key part of the fluent API that intercept, modify, and enhance AI-driven interactions. The key benefits include encapsulating common Generative AI patterns, transforming data sent to and from Large Language Models (LLMs), and providing portability across various models and use cases.

Advisors process ChatClientRequest and ChatClientResponse objects. The framework chains advisors by their getOrder() values (lower values execute first), with the final…
