springboot整合deepseek技术指南（2025版）

环境准备



    com.deepseek
    deepseek-java-sdk
    2.5.0


    org.springframework.boot
    spring-boot-starter-webflux

配置中心设置

# application.yml
deepseek:
  api:
    base-url: https://api.deepseek.com/v2
    token: ${deepseek_api_key} # 从环境变量读取
  timeout: 10000 # 毫秒
  retry:
    max-attempts: 3
    backoff: 2000

核心服务类实现

@service
@slf4j
public class deepseekservice {
    @value("${deepseek.api.base-url}")
    private string baseurl;
    @value("${deepseek.api.token}")
    private string apitoken;
    private final webclient webclient;
    public deepseekservice(webclient.builder webclientbuilder) {
        this.webclient = webclientbuilder.baseurl(baseurl)
                .defaultheader("authorization", "bearer " + apitoken)
                .build();
    }
    /**
     * 通用ai请求方法
     * @param request 包含prompt和参数的dto对象
     * @return 生成的文本内容
     */
    public mono generatecontent(deepseekrequest request) {
        return webclient.post()
                .uri("/generate")
                .bodyvalue(request)
                .retrieve()
                .bodytomono(deepseekresponse.class)
                .timeout(duration.ofmillis(10000))
                .retrywhen(retry.backoff(3, duration.ofseconds(2)))
                .map(response -> {
                    if (response.getcode() != 200) {
                        throw new deepseekexception(response.getmsg());
                    }
                    return response.getdata().gettext();
                });
    }
}

异常处理增强

@restcontrolleradvice
public class deepseekexceptionhandler {
    @exceptionhandler(deepseekexception.class)
    public responseentity handledeepseekexception(deepseekexception ex) {
        errorresult error = new errorresult("deepseek_error", 
            "ai服务异常: " + ex.getmessage());
        return responseentity.status(502).body(error);
    }
    @exceptionhandler(webclientresponseexception.class)
    public responseentity handlewebclientexception(webclientresponseexception ex) {
        errorresult error = new errorresult("network_error",
            "接口通信失败: " + ex.getstatuscode());
        return responseentity.status(503).body(error);
    }
}

实际应用场景

场景1：自动生成文章草稿

@postmapping("/generate-article")
public mono> generatearticle(@requestbody articlerequest request) {
    string prompt = string.format("生成一篇关于%s的技术文章，包含以下要素：%s", 
        request.gettopic(), 
        string.join(",", request.getkeywords()));
    deepseekrequest deepseekrequest = new deepseekrequest(
        prompt, 
        "technical_writing", 
        0.7, 
        1024
    );
    return deepseekservice.generatecontent(deepseekrequest)
            .map(content -> {
                string formatted = contentformatter.formatmarkdown(content);
                return responseentity.ok(formatted);
            });
}

场景2：智能内容优化

@postmapping("/optimize-content")
public mono> optimizecontent(
    @requestbody string rawcontent) {
    string optimizationprompt = "优化以下内容使其更符合新媒体传播：\n" + rawcontent;
    return deepseekservice.generatecontent(
            new deepseekrequest(optimizationprompt, "content_optimization", 0.5, 512))
        .zipwith(deepseekservice.generatecontent(
            new deepseekrequest("生成5个爆款标题", "title_generation", 0.9, 128)))
        .map(tuple -> {
            contentoptimization result = new contentoptimization();
            result.setoptimizedcontent(tuple.gett1());
            result.settitles(arrays.aslist(tuple.gett2().split("\n")));
            return responseentity.ok(result);
        });
}

测试方案

@springboottest
class deepseekservicetest {
    @autowired
    private deepseekservice deepseekservice;
    @test
    void testtechnicalwriting() {
        deepseekrequest request = new deepseekrequest(
            "用java解释量子计算基础",
            "technical_writing",
            0.6,
            800
        );
        stepverifier.create(deepseekservice.generatecontent(request))
            .assertnext(content -> {
                asserttrue(content.contains("量子比特"));
                asserttrue(content.length() > 500);
            })
            .verifycomplete();
    }
}
