简介

上篇文章： Spring AI--快速入门2：上下文记忆+会话隔离-CSDN博客实现了上下文记忆，数据存放在内存。

本文实现的功能：对话记录持久化、打断对话、删除对话记录。

数据库依赖

添加数据库依赖，关键依赖是：

<!--会话记忆-->
<dependency>
    <groupId>org.springframework.ai</groupId>
    <artifactId>spring-ai-starter-model-chat-memory-repository-jdbc</artifactId>
    <version>1.1.0</version>
</dependency>
<!-- MySQL 驱动 -->
<dependency>
    <groupId>mysql</groupId>
    <artifactId>mysql-connector-java</artifactId>
    <version>8.0.32</version>
</dependency>

整个pom.xml如下：

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

        <artifactId>spring-boot-starter-parent</artifactId>

        <relativePath/> <!-- lookup parent from repository -->
    </parent>

                <version>${spring-ai.version}</version>

        </dependency>

        <!-- OpenAI 模型依赖 -->

            <groupId>org.springframework.ai</groupId>
            <artifactId>spring-ai-starter-model-openai</artifactId>
        </dependency>

        <!--spring3.x版本建议加上此依赖，否则会有启动的提示-->
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-validation</artifactId>
        </dependency>

        <!--会话记忆-->
        <dependency>
            <groupId>org.springframework.ai</groupId>
            <artifactId>spring-ai-starter-model-chat-memory-repository-jdbc</artifactId>
            <version>1.1.0</version>
        </dependency>
        <!-- MySQL 驱动 -->
        <dependency>
            <groupId>mysql</groupId>
            <artifactId>mysql-connector-java</artifactId>

        </dependency>

        <dependency>
            <groupId>org.projectlombok</groupId>
            <artifactId>lombok</artifactId>

        </dependency>
    </dependencies>

        <plugins>
            <plugin>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-maven-plugin</artifactId>
            </plugin>

            <plugin>
                <groupId>org.apache.maven.plugins</groupId>

                <!-- 指定maven编译的jdk版本。对于JDK8，写成8或者1.8都可以 -->
                <configuration>
                    <source>${java.version}</source>
                    <target>${java.version}</target>
                </configuration>
            </plugin>
        </plugins>
    </build>

</project>

数据库配置

1.创建数据库

CREATE DATABASE `spring-ai` CHARACTER SET utf8mb4 COLLATE utf8mb4_general_ci;

2.配置SQL脚本

新建sql建表文件，放到此路径：resources/sql/schema-mysql.sql

CREATE TABLE IF NOT EXISTS SPRING_AI_CHAT_MEMORY
(
    conversation_id VARCHAR(36) NOT NULL,
    content         TEXT        NOT NULL,
    type            VARCHAR(10) NOT NULL,
    `timestamp`     TIMESTAMP   NOT NULL,
    CONSTRAINT TYPE_CHECK CHECK (type IN ('USER', 'ASSISTANT', 'SYSTEM', 'TOOL'))
);

3.application.yml

需要配置数据库信息、配置使用jdbc作为持久化方式（并指定建表sql文件）。

关键配置是：

spring:
  ai:
    chat:
      memory:
        repository:
          jdbc:
            initialize-schema: always
            schema: classpath:sql/schema-mysql.sql
  
  datasource:
    url: jdbc:mysql://192.168.80.193:3306/spring-ai?characterEncoding=UTF-8&serverTimezone=Asia/Shanghai
    username: root
    password: 222333
    driver-class-name: com.mysql.cj.jdbc.Driver

整个application.yml配置如下：

spring:
  application:
    name: 1_spring_ai_alibaba
  ai:
    openai:
      # URL前缀
      base-url: https://dashscope.aliyuncs.com/compatible-mode
      api-key: sk-82e1084be1194e218f0794af9c861e39
      chat:
        # URL后缀，默认为：/v1/chat/completions。spring ai会自动将spring.ai.openai拼接到前边。
        completions-path: /v1/chat/completions
        options:
          model: qwen-plus
          temperature: 0.8
          top-p: 0.7
    chat:
      memory:
        repository:
          jdbc:
            initialize-schema: always
            schema: classpath:sql/schema-mysql.sql
  datasource:
    url: jdbc:mysql://192.168.80.193:3306/spring-ai?characterEncoding=UTF-8&serverTimezone=Asia/Shanghai
    username: root
    password: 222333
    driver-class-name: com.mysql.cj.jdbc.Driver
    
logging:
  level:
    org.springframework.ai.chat.client.advisor: debug

# knife4j的增强配置，不需要增强可以不配
