# 75.16 使用@ServerEndpoint创建WebSocket端点

如果想在使用内嵌容器的Spring Boot应用中使用`@ServerEndpoint`，你需要声明一个单独的`ServerEndpointExporter` `@Bean`：

```java
@Bean
public ServerEndpointExporter serverEndpointExporter() {
    return new ServerEndpointExporter();
}
```

该bean将使用底层的WebSocket容器注册任何被`@ServerEndpoint`注解的beans。当部署到一个单独的servlet容器时，该角色将被一个servlet容器初始化方法执行，`ServerEndpointExporter` bean也就不需要了。
