SpringBoot异步注释@Async的并发陷阱

@EnableAsync
@SpringBootApplication
public class Application {

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

@Service
public class CategoryService {

     @Async
     public void add(Category category) {
        // add category
     }
}

@RestController
@RequestMapping("/category")
public class CategoryController {

     @Autowired
     private CategoryService categoryService;
  
     @PostMapping("/add")
     public void add(@RequestBody category) {
        categoryService.add(category);
     }
}

executor.submit(task);

protected void doExecute(Runnable task) {
    Thread thread = (this.threadFactory != null ? this.threadFactory.newThread(task) : createThread(task));
    thread.start();
}
