使用DeferredResult时响应主体为空 [英] Response body is empty when using DeferredResult

问题描述

在Java Config中使用DeferredResult时，响应主体为空.

Response body is empty when using DeferredResult with Java Config.

控制器:

@Controller
public class HomeController {

    @RequestMapping("/")
    public DeferredResult<ModelAndView> home() {
        final DeferredResult<ModelAndView> result = new DeferredResult<>();

        Timer timer = new Timer();
        timer.schedule(new TimerTask() {
            @Override
            public void run() {
                result.setResult(new ModelAndView("home", Collections.singletonMap("name", "World")));
            }
        }, 2);

        return result;
    }
}

配置:

@Configuration
@ComponentScan(basePackages = "to.talk.gzip.test")
@PropertySource(value = "classpath:/application.properties")
@EnableWebMvc
public class AppConfig {

    @Bean
    public ViewResolver mustacheViewResolver() {
        MustacheViewResolver resolver = new MustacheViewResolver();
        resolver.setPrefix("views/");
        resolver.setSuffix(".html");
        return resolver;
    }
}
