环境

jdk 17
springboot 3.0.2
maven 3.6.3

需求

需要让大模型根据输入的姓名首字母和目标长度生成推荐的姓名和对应的寓意，要求返回如下的JSON数组给前端：

[
    {
        "name": "吴海",
        "meaning": "寓意胸怀宽广，如大海般包容，志向远大。"
    },
    {
        "name": "吴阳",
        "meaning": "寓意光明磊落，前程似锦，充满希望。"
    },
   ......
]

踩坑记录

已经配置好了大模型和AiService：

@Configuration
public class LLMConfig {

    @Bean(name = "qwen")
    public ChatModel QwenChatModel() {
        return OpenAiChatModel.builder()
                .baseUrl("https://dashscope.aliyuncs.com/compatible-mode/v1")
                .apiKey(System.getenv("qwen-api-key"))
                .modelName("qwen-plus")
                .logRequests(true)
                .logResponses(true)
                .build();
    }


    @Bean
    public ChatAssistant chatAssistant(@Qualifier("qwen") ChatModel chatModel) {
        return AiServices.builder(ChatAssistant.class)
                .chatModel(chatModel)
                .inputGuardrails()
                .build();
    }
}

AiSercice对应的接口：

public interface ChatAssistant {


    String chat(String prompt);

    @SystemMessage("你是一个专业的起名专家，需要根据用户指定的姓名长度和姓名的第一个字生成10个中文名字，并给出每个名字的寓意")
    List<NameOutput> generateNames(String prompt);

}

解决方法

参考GitHub上的issue：Structured outputs: Support List with prompting
1、如果需要结构化输出，配置ChatModel的时候需要配置JSON响应格式支持并严格输出JSON响应格式：

@Bean(name = "qwen")
    public ChatModel QwenChatModel() {
        return OpenAiChatModel.builder()
                .baseUrl("https://dashscope.aliyuncs.com/compatible-mode/v1")
                .apiKey(System.getenv("qwen-api-key"))
                .modelName("qwen-plus")
                .logRequests(true)
                .logResponses(true)
                .supportedCapabilities(Capability.RESPONSE_FORMAT_JSON_SCHEMA) // 添加 JSON 响应格式支持
                .strictJsonSchema(true) // 严格输出 JSON 响应格式
                .build();
    }

2、需要在输出映射类中添加无参构造方法，springboot中可以通过@NoArgsConstructor注解实现

@Data
@AllArgsConstructor
@NoArgsConstructor
public class NameOutput {
    @Description("名称")
    private String name;
    @Description("寓意")
    private String meaning;
}

注意：不是所有大模型都支持以配置的方式规定格式化输出，目前测试下来Qwen、gemini、gork是没问题的，对于那些不支持的大模型，就只能在SystemMessage里对其输出格式进行提示，但这种方式不能保证稳定性

效果

整体的项目结构：
在这里插入图片描述
控制层：

@Slf4j
@RestController
@RequestMapping("/chat")
public class ChatController {

    @Autowired
    private ChatAssistant chatAssistant;

    @PostMapping(value = "/generateNames", produces = "application/json;charset=utf-8")
    public List<NameOutput> generateNames(@RequestBody NameRequest request) {
        String prompt = String.format("请根据以下条件生成中文名字：第一个字是'%s'，总长度为%d个字", request.getFirstChar(), request.getLength());
        return chatAssistant.generateNames(prompt);
    }

}
