+# Spring AI Alibaba Elasticsearch Memory 模块
+
+[English](./README.md)
+
+## 简介
+
+Spring AI Alibaba Elasticsearch Memory 模块是 Spring AI Alibaba 项目的核心组件之一，
+专门提供基于 Elasticsearch 的存储解决方案。该模块利用 Elasticsearch 的全文检索和分布式特性，为 AI 应用提供快速、可靠的对话历史和上下文数据存储服务，使 AI 系统能够"记住"之前的交互，从而提供更连贯、更个性化的用户体验。
+
+## 主要特性
+
+- **Elasticsearch 存储**：利用 Elasticsearch 的高性能和分布式特性，实现对话历史和上下文数据的快速存取
+- **与 Spring 生态无缝集成**：完美兼容 Spring 框架和 Spring Boot 应用
+- **灵活的记忆管理**：支持设置对话记忆大小限制，自动清理过期对话
+
+## 快速开始
+
+### Maven 依赖
+
+将以下依赖添加到你的项目中：
+
+```xml
+<dependency>
+    <groupId>com.alibaba.cloud.ai</groupId>
+    <artifactId>spring-ai-alibaba-starter-memory-elasticsearch</artifactId>
+    <version>${latest.version}</version>
+</dependency>
+```
+
+### 基本配置
+
+在`application.properties`或`application.yml`中添加 Elasticsearch 配置：
+
+```yaml
+elasticsearch:
+  host: localhost
+  port: 9200
+  scheme: http
+  # 如果有认证需求
+  # username: elastic
+  # password: password
+```
+
+### 示例代码
+
+```java
+import org.springframework.ai.chat.client.ChatClient;
+import org.springframework.beans.factory.annotation.Autowired;
+import org.springframework.web.bind.annotation.*;
+import reactor.core.publisher.Flux;
+import com.alibaba.cloud.ai.memory.elasticsearch.ElasticsearchChatMemoryRepository;
+import org.springframework.ai.chat.memory.ChatMemory;
+import org.springframework.ai.chat.memory.MessageWindowChatMemory;
+
+import javax.servlet.http.HttpServletResponse;
+
+@RestController
+public class ChatController {
+
+    @Autowired
+    private ElasticsearchChatMemoryRepository elasticsearchChatMemoryRepository;
+
+    @Autowired
+    private ChatClient chatClient;
+
+    /**
+     * 流式聊天接口（基于 Elasticsearch 存储对话历史）
+     *
+     * @param prompt 用户输入的问题或提示
+     * @param chatId 对话 ID，用于标识当前会话
+     * @param response HttpServletResponse 对象，用于设置响应编码
+     * @return 返回流式响应内容（Flux<String>），逐步输出 AI 回答
+     */
+    @GetMapping("/chat")
+    public Flux<String> elasticsearchChat(
+            @RequestParam("prompt") String prompt,
+            @RequestParam("chatId") String chatId,
+            HttpServletResponse response) {
+
+        // 设置响应字符编码为 UTF-8，确保中文等字符正确显示
+        response.setCharacterEncoding("UTF-8");
+
+        // 构建带消息窗口的记忆组件，最多保留最近 10 条消息
+        ChatMemory chatMemory = MessageWindowChatMemory.builder()
+                .chatMemoryRepository(elasticsearchChatMemoryRepository)
+                .maxMessages(10)
+                .build();
+
+        // 发起 AI 模型调用，并启用记忆功能
+        return chatClient.prompt(prompt)
+                .advisors(new MessageChatMemoryAdvisor(chatMemory))
+                .advisors(a -> a
+                        .param("chatMemoryConversationId", chatId)
+                        .param("chatMemoryRetrieveSize", 100)
+                )
+                .stream()     // 使用流式响应
+                .content();   // 获取内容流
+    }
+}
+```
+
+## 高级特性
+
+### 自定义 Elasticsearch 配置
+
+可以通过`ElasticsearchConfig`类来自定义更复杂的 Elasticsearch 配置：
+
+```java
+ElasticsearchConfig config = new ElasticsearchConfig();
+config.setHost("localhost");
+config.setPort(9200);
+config.setScheme("https"); // 使用HTTPS
+config.setUsername("elastic");
+config.setPassword("password");
+
+// 使用集群多节点配置
+List<String> nodes = new ArrayList<>();
+nodes.add("node1:9200");
+nodes.add("node2:9200");
+config.setNodes(nodes);
+
+ElasticsearchChatMemoryRepository repository = new ElasticsearchChatMemoryRepository(config);
+```
+
+### 管理记忆大小
+
+```java
+// 为特定对话清理过期消息，保留最新的消息
+// 参数：对话ID，最大消息数量，要删除的消息数量
+repository.clearOverLimit("conversation-123", 10, 5);
+```
