@SpringBootApplication
@ServletComponentScan(basePackages = "com.jackhu.diveinspringboot.web.servlet")
public class Application {
    public static void main(String[] args) {
        SpringApplication.run(Application.class, args);
    }
}

输出结果

2、异步Servlet 组件

protected void doGet(HttpServletRequest req, HttpServletResponse resp)
        throws ServletException, IOException {
    AsyncContext asyncContext = req.getAsyncContext();
    asyncContext.start(() -> {
        try {
resp.getWriter().print("hello hll");
        } catch (IOException e) {
            e.printStackTrace();
        }
    });
// 触发完成
asyncContext.complete();
}

提示错误：

原因：

@WebServlet默认不支持异步，需要手动开启

/**
 * @return asynchronous operation supported by this Servlet
 */
boolean asyncSupported() default false;

修改 asyncSupported = true

@WebServlet(urlPatterns = "/my/servlet",
        asyncSupported = true)
