This scope is used when two-way communication between a customer and remote site is enabled using the websocket protocol. It is mainly useful when applications are used by multiple users with simultaneous actions.

Here, an HTTP request is used to do an initial handshake, and once it is established, the TCP port remains open for a client and server for communication. The websocket bean is similar to a singleton, and injected into Spring controllers. The life of a websocket bean is longer compared to a typical websocket session. The following example shows how a websocket is declared using Scope annotation and traditional XML configuration:

//Using @Scope annotation
@Scope(scopeName = "websocket")

//Using XML configuration 
<bean id="..." class="com.packt.scope.WebsocketExampleTest" scope="websocket" />
