spring-boot 整合websocket

spring-boot-starter-parent   1.5.7.RELEASE版本

@ServerEndpoint(value = "/echo/{userId}", configurator = SpringConfigurator.class)

这样配置无法生效，必须加一个配置类

@Configuration
public class SimpleWebSocketConfig {


  
@Bean
  public ServerEndpointRegistration echoEndpoint() {  
    return new ServerEndpointRegistration("/echo/{userId}", EchoEndpoint.class);  
  }  
  
  @Bean  
  public ServerEndpointExporter endpointExporter() {  
    return new ServerEndpointExporter();  
  }  
  
}
