代码如何决定使用WebSphereRequestUpgradeStrategy和TomcatRequestUpgradeStrategy?

TomcatRequestUpgradeStrategy 这个不起作用,而那个用 WebSphereRequestUpgradeStrategy 很好用。我不清楚逻辑是如何决定这一点的?我已经在我的pom中设置了spring boot starter tomcat。所以我不清楚它是如何导致它使用TomcatRequestUpgradeStrategy的。有人能帮我吗?

工作:

SRTServletRequest31.upgrade(Class<T>) line: 157 
WsocHandlerImpl.handleRequest(HttpServletRequest, HttpServletResponse, ServerEndpointConfig, Map<String,String>, boolean) line: 268 
ServerContainerExt.doUpgrade(HttpServletRequest, HttpServletResponse, ServerEndpointConfig, Map<String,String>) line: 288   
NativeMethodAccessorImpl.invoke0(Method, Object, Object[]) line: not available [native method]  
NativeMethodAccessorImpl.invoke(Object, Object[]) line: 62  
DelegatingMethodAccessorImpl.invoke(Object, Object[]) line: 43  
Method.invoke(Object, Object...) line: 498  
WebSphereRequestUpgradeStrategy.upgradeInternal(ServerHttpRequest, ServerHttpResponse, String, List<Extension>, Endpoint) line: 87  
WebSphereRequestUpgradeStrategy(AbstractStandardUpgradeStrategy).upgrade(ServerHttpRequest, ServerHttpResponse, String, List<WebSocketExtension>, Principal, WebSocketHandler, Map<String,Object>) line: 119    
DefaultHandshakeHandler(AbstractHandshakeHandler).doHandshake(ServerHttpRequest, ServerHttpResponse, WebSocketHandler, Map<String,Object>) line: 281    
WebSocketHttpRequestHandler.handleRequest(HttpServletRequest, HttpServletResponse) line: 166

不工作:

SRTServletRequest31.upgrade(Class<T>) line: 157 
RequestWrapper(HttpServletRequestWrapper).upgrade(Class<T>) line: 399   
HttpSessionSecurityContextRepository$Servlet3SaveToSessionRequestWrapper(HttpServletRequestWrapper).upgrade(Class<T>) line: 399 
HttpServlet3RequestFactory$Servlet3SecurityContextHolderAwareRequestWrapper(HttpServletRequestWrapper).upgrade(Class<T>) line: 399  
UpgradeUtil.doUpgrade(WsServerContainer, HttpServletRequest, HttpServletResponse, ServerEndpointConfig, Map<String,String>) line: 234   
WsServerContainer.doUpgrade(HttpServletRequest, HttpServletResponse, ServerEndpointConfig, Map<String,String>) line: 265    
TomcatRequestUpgradeStrategy.upgradeInternal(ServerHttpRequest, ServerHttpResponse, String, List<Extension>, Endpoint) line: 72 
TomcatRequestUpgradeStrategy(AbstractStandardUpgradeStrategy).upgrade(ServerHttpRequest, ServerHttpResponse, String, List<WebSocketExtension>, Principal, WebSocketHandler, Map<String,Object>) line: 119   
DefaultHandshakeHandler(AbstractHandshakeHandler).doHandshake(ServerHttpRequest, ServerHttpResponse, WebSocketHandler, Map<String,Object>) line: 281    
WebSocketHttpRequestHandler.handleRequest(HttpServletRequest, HttpServletResponse) line: 166

请让我知道如果你需要更多的细节。感谢您的回复。

我找到了问题的答案。这可能对将来的其他人有所帮助。

DefaultHandshakeHandler org.apache.tomcat.websocket.server.WsHttpUpgradeHandler 类加载器中存在。因为pom依赖项中有tomcat嵌入websocket,所以存在这个类。所以,即使我是在自由号上跑步,这也被触发了。从pom中删除相同的内容,帮助我解决了问题。
