最近在学习java接入AI大模型
记录下java接入AI大模型的方式,比较典型的有4种。
1.sdk接入：就是AI大模型中有相关的文档，利用官方提供的工具包接口即可，下面是提供的示例

<!-- https://mvnrepository.com/artifact/com.alibaba/dashscope-sdk-java -->
<dependency>
    <groupId>com.alibaba</groupId>
    <artifactId>dashscope-sdk-java</artifactId>
    <version>2.19.1</version>
</dependency>

2.http接入

public class HttpAiInvoke {
    public static void main(String[] args) {
        // 替换为你的实际 API 密钥
        String url = "https://dashscope.aliyuncs.com/api/v1/services/aigc/text-generation/generation";

        // 设置请求头
        Map<String, String> headers = new HashMap<>();
        headers.put("Authorization", "Bearer " + TestApiKey.API_KEY);
        headers.put("Content-Type", "application/json");

        // 设置请求体
        JSONObject requestBody = new JSONObject();
        requestBody.put("model", "qwen-plus");

        JSONObject input = new JSONObject();
        JSONObject[] messages = new JSONObject[2];

        JSONObject systemMessage = new JSONObject();
        systemMessage.put("role", "system");
        systemMessage.put("content", "You are a helpful assistant.");
        messages[0] = systemMessage;

        JSONObject userMessage = new JSONObject();
        userMessage.put("role", "user");
        userMessage.put("content", "你是谁？");
        messages[1] = userMessage;

        input.put("messages", messages);
        requestBody.put("input", input);

        JSONObject parameters = new JSONObject();
        parameters.put("result_format", "message");
        requestBody.put("parameters", parameters);

        // 发送请求
        HttpResponse response = HttpRequest.post(url)
                .addHeaders(headers)
                .body(requestBody.toString())
                .execute();

        // 处理响应
        if (response.isOk()) {
            System.out.println("请求成功，响应内容：");
            System.out.println(response.body());
        } else {
            System.out.println("请求失败，状态码：" + response.getStatus());
            System.out.println("响应内容：" + response.body());
        }
    }
}

3.Spring AI接入
引用对应的依赖接口

<dependency>
    <groupId>com.alibaba.cloud.ai</groupId>
    <artifactId>spring-ai-alibaba-starter</artifactId>
    <version>1.0.0-M6.1</version>
</dependency>

4.Langchain4j方式
和Spring AI差不多

<!-- https://mvnrepository.com/artifact/dev.langchain4j/langchain4j-community-dashscope -->
<dependency>
    <groupId>dev.langchain4j</groupId>
    <artifactId>langchain4j-community-dashscope</artifactId>
    <version>1.0.0-beta2</version>
</dependency>
