Spring AI Alibaba集成阿里云百炼大模型应用

文章目录

阿里云百炼推出的智能体应用、工作流应用和智能体编排应用，有效解决了大模型在处理私有领域问题、获取最新信息、遵循固定流程以及自动规划复杂项目等方面的局限，显著拓展了其应用范围。

1.准备工作

登录阿里百炼平台，新建一个appkey，然后创建一个智能体应用，获取一个appId
开发环境：JDK17+、SpringBoot3.x+

2.引入maven依赖

3.application.yml

yaml 复制代码

spring:
  ai:
    dashscope:
      agent:
        app-id: xxxx # 大模型应用ID，需要在平台发布(创建时会指定使用的模型)
      api-key: xxxx # 百炼API Key
      workspace-id: xxxx # 业务空间ID，可选，未配置时使用主账号空间

4.调用

4.1.非流式调用

java 复制代码

/**
 * 非流式调用
 */
@RestController
@RequestMapping("/ai")
public class BailianAgentRagController {
    private static final Logger logger = LoggerFactory.getLogger(BailianAgentRagController.class);
    private DashScopeAgent agent;

    @Value("${spring.ai.dashscope.agent.app-id:xxx}")
    private String appId;

    public BailianAgentRagController(DashScopeAgentApi dashscopeAgentApi) {
        this.agent = new DashScopeAgent(dashscopeAgentApi);
    }

    @GetMapping("/bailian/agent/call")
    public String call(@RequestParam(value = "message",
            defaultValue = "如何使用SDK快速调用阿里云百炼的应用?") String message) {
        ChatResponse response = agent.call(new Prompt(message, DashScopeAgentOptions.builder().withAppId(appId).build()));
        if (response == null || response.getResult() == null) {
            logger.error("chat response is null");
            return "chat response is null";
        }

        AssistantMessage app_output = response.getResult().getOutput();
        return app_output.getContent();
    }
}

4.2.流式调用

java 复制代码

/**

    private static final Logger logger = LoggerFactory.getLogger(BailianAgentRagStreamController.class);
    private DashScopeAgent agent;

    private String appId;

				DashScopeAgentOptions.builder()
						.withSessionId("current_session_id")
						.withIncrementalOutput(true)
						.withHasThoughts(true)
						.build());
    }

    @GetMapping(value="/bailian/agent/stream", produces="text/event-stream;charset=utf-8")
    public Flux<String> stream(@RequestParam(value = "message",
              defaultValue = "你好，请问你的知识库文档主要是关于什么内容的?") String message, HttpServletResponse re) {
        re.setContentType("text/event-stream;charset=utf-8");
        return agent.stream(new Prompt(message, DashScopeAgentOptions.builder().withAppId(appId).build())).map(response -> {
    	    if (response == null || response.getResult() == null) {
                  logger.error("chat response is null");
    		return "chat response is null";
    	    }
    
    	    AssistantMessage app_output = response.getResult().getOutput();
    	    String content = app_output.getContent();
    
    	    return content;
          });
    }

    @GetMapping(value="/bailian/agent/stream/html", produces="text/html;charset=utf-8")
    public Flux<String> streamHtml(@RequestParam(value = "message",
            defaultValue = "你好，请问你的知识库文档主要是关于什么内容的?") String message) {
        return agent.stream(new Prompt(message, DashScopeAgentOptions.builder().withAppId(appId).build())).map(response -> {
            if (response == null || response.getResult() == null) {

            AssistantMessage app_output = response.getResult().getOutput();
            String content = app_output.getContent();

            return content;
        });
    }
