Spring Boot 4 & Spring AI 2.0 Helper Skill

Overview

Provides expert guidance on Spring Boot 4, Spring Framework 7, and Spring AI 2.0.

Spring Boot 4 Key Changes

  • Requires Java 17+ (Java 25 fully supported)
  • Built on Spring Framework 7
  • Jakarta EE 11 namespace (jakarta.* everywhere)
  • Virtual threads auto-configured via spring.threads.virtual.enabled=true

Spring AI 2.0 ChatClient

java
ChatClient chatClient = chatClientBuilder
    .defaultSystem("You are a helpful assistant")
    .defaultTools(myTool)
    .build();

String response = chatClient.prompt()
    .user("Hello!")
    .call()
    .content();

Tool Calling

java
@Bean
@Description("Get the current weather for a city")
public Function<WeatherRequest, WeatherResponse> weatherFunction() {
    return request -> new WeatherResponse(72.0, "sunny");
}

Advisors

  • MessageChatMemoryAdvisor - conversation memory
  • ToolCallAdvisor - tool execution
  • Custom advisors implement CallAroundAdvisor

Agent Patterns

  • Skill-based agents: Use SkillsTool with Markdown skill files
  • Sub-agents: Delegate tasks via TaskTool to specialized models
  • Memory: MessageWindowChatMemory for conversation history

Auto-configuration

  • Set OPENAI_API_KEY env var
  • Property: spring.ai.openai.chat.options.model=gpt-4o

Virtual Threads with Spring Boot 4

properties
spring.threads.virtual.enabled=true

Automatically uses virtual threads for Tomcat and @Async tasks.
