这里以调用GPT4o为例

SpringAI调用OpenAI Demo插图(2)

后来为了测试JDK8是否可用将版本调整成了2.7.2 结果不能使用

SpringAI调用OpenAI Demo插图(3)

因国内无法直接访问按了个nginx代理

配置ChatClient另外种方式

SpringAI调用OpenAI Demo插图(6)

SpringAI调用OpenAI Demo插图(7)

特定的对话风格或角色，通常建议详细定义你希望模型如何回应，然后在你的应用中相应地构建提示其实就是对话之前

SpringAI调用OpenAI Demo插图(11)

你也可以为每一个接口设置单独的预定义角色例如

SpringAI调用OpenAI Demo插图(12)

以流的方式返回

SpringAI调用OpenAI Demo插图(13)

这个在postMan中不好提现

可以直接在浏览器

可以看到它是以流的方式返回的,但是乱码

除了使用nginx转发还可以用本地代理只要在应用启动前配置好就行

关于ChatClient和ChatModel

ChatClient:较为通用

ChatModel:设置模型独有功能

SpringAI调用OpenAI Demo插图(19)

SpringAI调用OpenAI Demo插图(20)

SpringAI调用OpenAI Demo插图(24)

下面使用ChatModel演示调用

可以参数中指定, 也可以application.properties中指定

文生语音

SpringAI调用OpenAI Demo插图(31)

下面做法是有问题的,因为你保存到resources目录下的话项目是打包之后运行的因此你第一次运行保存之后是读不到的要读只能重新启动,这里只是演示就先这样了

关于语音转文本

SpringAI调用OpenAI Demo插图(36)

SpringAI调用OpenAI Demo插图(37)

关于多模态(意思就是你可以要发文本,要发图片,要发语音)

SpringAI调用OpenAI Demo插图(38)

意思只能用GPT4或4o模型才能用多模态

关于Function call 应对大模型无法获取实时信息的弊端

比如说,我现在问今天杭州火车东站的客流量是多少,这样GPT肯定无法回答

那么需要怎么办呢我们可以调用第三方接口得到信息再告知GPT 然后GPT回答问题

SpringAI调用OpenAI Demo插图(43)

SpringAI调用OpenAI Demo插图(44)

大概解释

例如我问杭州有多少人口

这类问题,GPT是无法回答的,当然现在GPT会查阅相关资料回答,假设

这句话里有 location和count两个关键

Function Call的作用是当问GPT一个类似问题之后,GPT用Function Call来回调我们的应用并携带关键信息 location和count信息,我们的应用去查数据库也好,去调用第三方接口也好,再告诉GPT 那么GPT就可以回答这个问题了

当GPT携带参数过来的时候会调用Function.apply(){}这个方法,那么我们在这个方法里写我们自己的逻辑可以查数据库,可以调用第三方接口

创建一个实现Function接口的类
