Spring WebSphere Liberty 上的 MVC，所有 Spring URL 上的 404

Question

Eclipse Oxygen with WebSphere Development Tools (WDT)，Spring MVC 4.3.14，WebSphere Liberty Core 18.0.0.1 on Java 8. 启用的 Liberty 功能（故意不是最新的）是：

<featureManager>
    <feature>adminCenter-1.0</feature>
    <feature>localConnector-1.0</feature>
    <feature>jaxrs-1.1</feature>
    <feature>concurrent-1.0</feature>
    <feature>webProfile-6.0</feature>
    <feature>jaxb-2.2</feature>
</featureManager>

上下文根上的 JSP 工作正常，所以这是正确的。此外，ibm-web-ext.xml 有 <context-root uri="/webapp/gatewaymvm/" />

Spring 启动日志记录表明我的 @Controller 类正在绑定到我期望的路径：

10:31:24,102 DEBUG org.springframework.web.servlet.mvc.method.annotation.RequestMappingHandlerMapping:Looking for request mappings in application context: WebApplicationContext for namespace 'Spring MVC Dispatcher-servlet': startup date [Thu Apr 05 10:31:22 CDT 2018]; parent: Root WebApplicationContext
....

然而，当我点击这些 URL 中的任何一个时，它们会产生 404 响应和如下日志条目：

10:32:40,067 DEBUG org.springframework.web.servlet.DispatcherServlet:DispatcherServlet with name 'Spring MVC Dispatcher' processing POST request for [/webapp/gatewaymvm/testPostJSONDoc]
10:32:40,067 DEBUG org.springframework.webflow.mvc.servlet.FlowHandlerMapping:No flow mapping found for request with URI '/webapp/gatewaymvm/testPostJSONDoc'
10:32:40,068 DEBUG org.springframework.web.servlet.mvc.method.annotation.RequestMappingHandlerMapping:Looking up handler method for path testPostJSONDoc
10:32:40,075 DEBUG org.springframework.web.servlet.mvc.method.annotation.RequestMappingHandlerMapping:Did not find handler method for [testPostJSONDoc]
10:32:40,076 WARN org.springframework.web.servlet.PageNotFound:No mapping found for HTTP request with URI [/webapp/gatewaymvm/testPostJSONDoc] in DispatcherServlet with name 'Spring MVC Dispatcher'

同一个应用程序，当部署到 "Traditional" WAS 时，按预期工作。我想对于 Liberty、Eclipse 下的 Liberty 或 Liberty 下的 Spring MVC，我明显遗漏了一些东西。

Answer 1

在我测试的某个时候，我的代码从当前请求构造了一个 URL，我看到 /webapp/gatewaymvm//resource，两个斜杠在一起。

所以我尝试从上下文根为 /webapp/gatewaymvm/ 的地方删除尾部斜杠，这解决了问题。来自 server.xml 如果我直接安装了 WAR，或者来自 application.xml 如果我在 EAR/Enterprise 项目中安装了 WAR。

有趣的是，JSP 使用尾部斜杠，但 Spring 路径没有。
