如何让我们的聊天内容能被ai一致记住，然后总结上下文去回答呢，这里我们要知道接口 ChatMemory,表示聊天记录的存储。它提供了向对话中添加消息、从对话中检索消息以及清除对话历史记录的方法，目前有两种实现， InMemoryChatMemory 和 CassandraChatMemory ，它们提供了聊天会话历史的存储，具体实现文档在springAi
1. 记忆实现
官网实现：
import static org.springframework.ai.chat.client.advisor.AbstractChatMemoryAdvisor.CHAT_MEMORY_CONVERSATION_ID_KEY;
import static org.springframework.ai.chat.client.advisor.AbstractChatMemoryAdvisor.CHAT_MEMORY_RETRIEVE_SIZE_KEY;
@Service
public class CustomerSupportAssistant {
private final ChatClient chatClient;
public CustomerSupportAssistant(ChatClient.Builder builder, VectorStore vectorStore, ChatMemory chatMemory) {
this.chatClient = builder
.defaultSystem("""
You are a customer chat support agent of an airline named "Funnair". Respond in a friendly,
helpful, and joyful manner.
Before providing information about a booking or cancelling a booking, you MUST always
get the following information from the user: booking number, customer first name and last name.
Before changing a booking you MUST ensure it is permitted by the terms.
If there is a charge for the change, you MUST ask the user to consent before proceeding.
""")
.defaultAdvisors(
new MessageChatMemoryAdvisor(chatMemory), // CHAT MEMORY
new QuestionAnswerAdvisor(vectorStore), // RAG
new SimpleLoggerAdvisor())
.defaultFunctions("getBookingDetails", "changeBooking", "cancelBooking") // FUNCTION CALLING
.build();
}
public Flux<String> chat(String chatId, String userMessageContent) {
return this.chatClient.prompt()
.user(userMessageContent)
.advisors(a -> a
.param(CHAT_MEMORY_CONVERSATION_ID_KEY, chatId)
.param(CHAT_MEMORY_RETRIEVE_SIZE_KEY, 100))
.stream().content();
}
}这里面的chatId就是你这个会话窗口的id，在这个id不变的情况下，它会自定义的去在总结100条对话记录，然后再回答你的问题
