配置 WebSocket
配置有两种方式：注解和 xml 。其作用就是将 WebSocket 处理器添加到注册中心。

更多配置细节可以参考：
javax.websocket如果不想使用 Spring 框架的 WebSocket API，你也可以选择基本的 javax.websocket。
首先，需要引入 API jar 包。

<!-- To write basic javax.websocket against --><dependency> <groupId>javax.websocket</groupId> <artifactId>javax.websocket-api</artifactId> <version>1.0</version></dependency>[url=][/url]
如果使用嵌入式 jetty，你还需要引入它的实现包：
[url=][/url]
<!-- To run javax.websocket in embedded server --><dependency> <groupId>org.eclipse.jetty.websocket</groupId> <artifactId>javax-websocket-server-impl</artifactId> <version>${jetty-version}</version></dependency><!-- To run javax.websocket client --><dependency> <groupId>org.eclipse.jetty.websocket</groupId> <artifactId>javax-websocket-client-impl</artifactId> <version>${jetty-version}</version></dependency> |
