Spring-集成websocket异常"No adapter for handler SockJsHttpRequestHandler"
Spring-Integration websocket exception "No adapter for handler SockJsHttpRequestHandler"
我正在尝试创建一个基于 Spring-Integration 的 websockets 服务器。我正在使用以下配置文件（目前）：
<int-websocket:server-container
id="serverWebSocketContainer"
path="websocket">
<int-websocket:sockjs />
</int-websocket:server-container>
<int:channel id="receiveMessage"/>
<int-websocket:inbound-channel-adapter
channel="receiveMessage"
container="serverWebSocketContainer" />
<int:service-activator
input-channel="receiveMessage"
output-channel="nullChannel"
ref="websocketActivator"
method="onReceiveMessage"
requires-reply="true"
send-timeout="60000"/>
问题是我总是遇到以下异常：

知道如何解决这个问题吗？
您的 DispatcherServlet 似乎无法检测到 DispatcherServlet.properties defaultStrategies。
SockJsHttpRequestHandler 的 HandlerAdapter 实际上是那些默认值中的第一个：
org.springframework.web.servlet.HandlerAdapter=org.springframework.web.servlet.mvc.HttpRequestHandlerAdapter,\
org.springframework.web.servlet.mvc.SimpleControllerHandlerAdapter,\
org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter
或者您的应用程序上下文中有一些无法处理 HttpRequestHandler 实现的自定义 HandlerAdapter bean。在这种情况下，您还应该为 HttpRequestHandlerAdapter 添加一个 bean。
SockJsHttpRequestHandler/WebSocketHttpRequestHandler 是 HttpRequestHandler
的子类
所以HttpRequestHandlerAdapter可以用来做它的适配器。确保您的 DispatcherServlet 配置文件包含此类型的 bean
例如：
将以下行添加到您的 dispatch-servlet.xml（或用于您的 dispatcher-servlet 的其他 xml 文件）
<bean class="org.springframework.web.servlet.mvc.HttpRequestHandlerAdapter"/>
