Java 使用Spring引导的异步服务

我正在尝试使用springboot运行基本异步服务。
我在调用请求时遇到异常。我不知道为什么会这样，我使用了oracle网站和jersey网站上的所有说明和代码片段。这里有我遗漏的东西吗？ 如果您需要更多信息，请询问我，我将相应地更新问题。多谢各位

SpringBoot默认情况下使用SpringMVC提供服务（您已经配置好使用），但是您正试图混用Jax-RS，因为这种混用，我只想回答如何用SpringMVC的方式来实现这一点

我是凭记忆写这封信的，所以如果我手指发胖，请告诉我

您的配置类应具有@enablesync

@SpringBootApplication
@EnableAsync
public class Application {
    public static void main(String[] args) {
        SpringApplication.run(Application.class, args);
    }
} 

这是你的控制器

@RestController
public class MyController {
    @Autowired
    MyService myService;

    //DeferredResult does not send a response until .setResult or setErrorResult is called
    public DeferredResult<String> myService() {
        DeferredResult<String> result = new DeferredResult<>();
        //I'm using Java8 lambda for brevity use an anonymous class instead if using less than java8
        myService.asyncLongOperation((operationResult) -> result.setResult(operationResult))
        return result;
    }
}

@RestController
公共类MyController{
@自动连线
我的服务我的服务；
//在调用.setResult或setErrorResult之前，DeferredResult不会发送响应
公共延迟结果myService（）{
DeferredResult=新的DeferredResult（）；
//为了简洁起见，我使用Java8 lambda，如果使用少于Java8，则使用匿名类
myService.asyncLongOperation（（operationResult）->result.setResult（operationResult））
返回结果；
}
}

我认为@Async需要在另一个类中才能正常工作，但请随意挑战我的假设，并将此方法保留在MyController中

@Service
public class MyService {
    @Async //This annotation replaces building your own thread
    public void asyncLongOperation(Consumer<String> consumer) {
        String pie = calculatePieWhichIsShorterThanPi();
        consumer.accept(pie);
    }
}

@服务
公共类MyService{
@Async//此注释替换构建自己的线程
公共void操作（使用者）{
字符串pie=CalculatePie，其长度短于Pi（）；
消费者接受（馅饼）；
}
}

您说过要使用JAX-RS，但您有一个带有Spring注释的Spring RestController。您必须选择是否要对REST端点使用Spring MVC或JAX-RS。您说过要使用JAX-RS，但您有一个带有Spring注释的Spring RestController。您必须选择是否要对REST端点使用SpringMVC或JAX-RS。
