# 导入依赖

<dependency>

<groupId>org.springframework.boot</groupId>

<artifactId>spring-boot-starter-websocket</artifactId>

</dependency>

# 注册Bean

* ServerEndpointExporter

@Configuration

public class WebSocketConfiguration {

@Bean

public ServerEndpointExporter serverEndpointExporter (){

return new ServerEndpointExporter();

}

}

# 使用注解开发WebSocket端点

@Component

@ServerEndpoint("/websocket") //必须以斜线开头,不然启动报错

public WebSocketEndpoint{

@OnMessage

@OnOpen

@OnClose

@OnError

}

# 注意

* Endpoint 被 @Component 注解标识,被IOC管理,但是每次连接请求都会创建新的对象

* @OnError 要添加参数:Throwable ,不然启动异常
