1、资源引入：

org.springframework.boot

spring-boot-starter-websocket

2、代码调用：

public class Application extends SpringBootServletInitializer implements WebSocketConfigurer {

public static void main(String[] args) {

BladeApplication.run(CommonConstant.APPLICATION_NAME, Application.class, args);

}

@Override

public void registerWebSocketHandlers(WebSocketHandlerRegistry registry) {

registry.addHandler(jobWebSocketHandler(), "/tasks").withSockJS();

}

@Bean

public WebSocketHandler jobWebSocketHandler() {

return new PerConnectionWebSocketHandler(JobWebSocketHandler.class);

}

3、运行后遇到的问题：
