Ollama provides multiple LLM AI models for specific purposes. The Spring AI supports almost all the AI LLM Models provided by Ollama. The Spring Ai Ollama Chat Properties allows one to set the basic properties of Ollama Chat such as the model, keep-alive, and format as well as the Ollama model options properties.
package com.example.springai.controller;
import org.springframework.ai.chat.client.ChatClient;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RestController;
@RestController
public class SpringAiController {
private final ChatClient chatClient;
public SpringAiController(ChatClient.Builder chatClient) {
this.chatClient = chatClient.build();
}
@GetMapping("/hello")
String hello() {
String helloPrompt = "Hello, I am learning Ai with Spring";
return this.chatClient.prompt().user(helloPrompt).call().content();
}
}
package com.example.springai;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
@SpringBootApplication
public class SpringAiApplication {
