我正在使用Grizzly 2.3.11测试Atmosphere 2.1.3。我已经创建了一个ManagedService（path =“/ chat”），但是我收到了这个错误：'没有AtmosphereHandler映射请求/ chat状态500消息服务器错误'。如果我将路径更改为ManagedService（path =“/”），则可以正常工作。我调试了一下，似乎org.atmosphere.cpr.AtmosphereRequest.getServletPath（）返回null，因此使用默认路径“/”，这是使我的测试使用ManagedService工作的原因（path =“/” ）。
我将非常感谢您的帮助，因为我需要使用一个类似ManagedService（path =“/ chat”）的路径。
注意：这篇文章与Atmosphere + Grizzly: No AtmosphereHandler maps request for /chat Status 500 Message Server Error有关
PD：这是我的主要测试类：

[Grizzly(7) SelectorRunner] WARN org.atmosphere.websocket.protocol.SimpleHttpProtocol - org.atmosphere.cpr.AtmosphereMappingException: No AtmosphereHandler maps request for /chat Status 500 Message Server Error
阿列克谢，
我正在调试这个问题，这些是我的测试和结果：
- 。当我在内部调用'http://localhost:8181/chat/a/b/c'这个请求建立时：'AtmosphereRequest{ contextPath= servletPath=/chat pathInfo=/a/b/c requestURI=/chat/a/b/c destroyable=true}'好吧，Http Get请求似乎工作正常。
- 。当我在内部调用'new WebSocket('ws://localhost:8181/chat/a/b/c')'时，这个请求构建为'AtmosphereRequest{ contextPath= servletPath=null pathInfo=null requestURI=/chat/a/b/c destroyable=true}'我认为问题（servletPath和pathInfo为null）只在我使用websockets时发生
我正在重新编译方法org.glassfish.grizzly.websockets.WebSocketEngine.upgrade（FilterChainContext ctx，HttpContent requestContent，Mapper mapper），并且param requestContent接收到以下值：
HttpRequestPacket (
method=GET
url=/chat/a/b/c
query=null
protocol=HTTP/1.1
content-length=-1
headers=[
upgrade=websocket
connection=Upgrade
host=localhost:8181
origin=http://localhost:8080
pragma=no-cache
cache-control=no-cache
sec-websocket-key=3pRm4vKnwqvRO8G0/WUNBw==
sec-websocket-version=13
sec-websocket-extensions=permessage-deflate; client_max_window_bits, x-webkit-deflate-frame
user-agent=Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/34.0.1847.116 Safari/537.36]
)
但在我的调试会话结束时，方法org.atmosphere.util.DefaultEndpointMapper.computePath（AtmosphereRequest req）接收带有此值的param req：AtmosphereRequest {contextPath = servletPath = null pathInfo = null requestURI = / chat / a / b / c destroyable = true}
好吧，我希望这些测试对你有一些价值，无论如何你需要更多的测试随时问。
这个问题在Grizzly 2.3.12中找到并修复。
