效果演示

DeepSeek key获取

第一步进入官网 DeepSeek官网https://www.deepseek.com/

 第二步使用手机号注册或登录

 第三步创建API keys并复制保存

Java调用官网DeepSeek

添加配置(properties/yml)

##官方DeepSeek对话补齐AIP
deepSeek.chat.url=https://api.deepseek.com/chat/completions
##DeepSeek key
deepSeek.key=you deepseek key

关键调用DeepSeek代码

    @Value("${deepSeek.chat.url}")
    private String deepSeekChatUrl;

    @Value("${deepSeek.key}")
    private String deepSeekKey;
