Java接入DeepSeek的保姆级教程(适合新手)_Java

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>

            <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>

            <version>20140107</version>
        </dependency>
 
 
    </dependencies>

3、创建实体类

@data
@builder
public class deeseekrequest {
    private string model;
    private list<message> messages;
 
    @data
    @builder
    public static class message {
        private string role;
        private string content;
    }
}

4、创建controller层

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();
 
    }
}
