[超详细]JAVA接入DeepSeek保姆级教学[小白]

前言

1、获取自己在DeepSeek上的token

2、引入依赖

3、创建实体类

4、创建Controller层

5、启动项目、调用自己的接口

前言

对于目前的DeepSeek大家应该都不是很陌生，目前也是最流行的一款AI软件了，所以为了让我们开发更全面，能够在自己的项目中融入AI那就会很全面了，所以这次的文章，将模拟一个基础案例，可以在这个基础案例迭代实现出你自己的AI。

话不多说，也不介绍我的网站了，直接开始进行一下流程。

使用的：JDK 17

1、获取自己在DeepSeek上的token

网站： DeepSeek | 深度求索，点击API开放平台找到API keys 获取自己的key，注意你的key一定要保存好了

2、引入依赖

这个就不多说了，在你的pom文件中引入相对应的依赖即可。

<dependencies><!-- https://mvnrepository.com/artifact/org.springframework.boot/spring-boot-starter-web --><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-web</artifactId><version>3.4.2</version></dependency><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-test</artifactId><version>3.4.2</version></dependency><!-- https://mvnrepository.com/artifact/org.projectlombok/lombok --><dependency><groupId>org.projectlombok</groupId><artifactId>lombok</artifactId><version>1.18.30</version><scope>provided</scope></dependency><!-- HTTP客户端 --><dependency><groupId>com.squareup.okhttp3</groupId><artifactId>okhttp</artifactId><version>4.9.0</version></dependency><!-- JSON处理 --><dependency><groupId>com.google.code.gson</groupId><artifactId>gson</artifactId><version>2.10.1</version></dependency><dependency><groupId>com.mashape.unirest</groupId><artifactId>unirest-java</artifactId><version>1.4.9</version></dependency><dependency><groupId>org.apache.httpcomponents</groupId><artifactId>httpclient</artifactId><version>4.3.6</version></dependency><dependency><groupId>org.apache.httpcomponents</groupId><artifactId>httpasyncclient</artifactId><version>4.0.2</version></dependency><dependency><groupId>org.apache.httpcomponents</groupId><artifactId>httpmime</artifactId><version>4.3.6</version></dependency><dependency><groupId>org.json</groupId><artifactId>json</artifactId><version>20140107</version></dependency></dependencies>

3、创建实体类

java">@Data
@Builder
public class DeeseekRequest {private String model;private List<Message> messages;@Data@Builderpublic static class Message {private String role;private String content;}
}

4、创建Controller层

java">package com.wdc.dk;import com.google.gson.Gson;
import com.mashape.unirest.http.HttpResponse;
import com.mashape.unirest.http.Unirest;
import com.mashape.unirest.http.exceptions.UnirestException;
import okhttp3.MediaType;
import okhttp3.OkHttpClient;
import okhttp3.Request;
import okhttp3.RequestBody;
import okhttp3.Response;
import org.junit.jupiter.api.Test;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.web.bind.annotation.*;import java.io.IOException;
import java.util.ArrayList;
import java.util.Collections;
import java.util.List;@RestController
public class AIController {private final Gson gson = new Gson();@PostMapping("tall")public String tallQuestion(@org.springframework.web.bind.annotation.RequestBody String question) throws IOException, UnirestException {Unirest.setTimeouts(0, 0);//DeeseekRequest: 自己的实体类名称List<DeeseekRequest.Message> messages = new ArrayList<>();
//给deepSeek一个角色messages.add(DeeseekRequest.Message.builder().role("system").content("你是一个语言学家").build());// question：说你自己想说的话messages.add(DeeseekRequest.Message.builder().role("user").content(question).build());DeeseekRequest requestBody = DeeseekRequest.builder().model("deepseek-chat").messages(messages).build();HttpResponse<String> response = Unirest.post("https://api.deepseek.com/chat/completions").header("Content-Type", "application/json").header("Accept", "application/json").header("Authorization", "Bearer "+"自己的key").body(gson.toJson(requestBody)).asString();return  response.getBody();}
}
