Spring on WebSphere URLs，404 s在所有Spring上

Question

使用WebSphere开发工具(WDT)的Eclipse氧气，Spring 4.3.14，Java8上的WebSphere Core 18.0.0.1。启用自由特性(故意不是最新的)如下：

<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JSPs运行良好，所以这是正确的。另外，ibm-web-ext.xml有<context-root uri="/webapp/gatewaymvm/" />。

Spring启动日志记录表明，我的@Controller类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
....
10:31:24,125 DEBUG org.springframework.web.servlet.mvc.method.annotation.RequestMappingHandlerMapping:1 request handler methods found on class mypackage.QueryTransactionController: {public mypackage.QueryTransResponse mypackage.QueryTransactionController.processRequest(mypackage.QueryTransRequest,javax.servlet.http.HttpServletRequest,javax.servlet.http.HttpServletResponse) throws java.io.IOException={[/QueryTransaction],methods=[POST],consumes=[application/json || application/xml],produces=[application/json || application/xml]}}
10:31:24,125 INFO org.springframework.web.servlet.mvc.method.annotation.RequestMappingHandlerMapping:Mapped "{[/QueryTransaction],methods=[POST],consumes=[application/json || application/xml],produces=[application/json || application/xml]}" onto public mypackage.QueryTransResponse mypackage.QueryTransactionController.processRequest(mypackage.QueryTransRequest,javax.servlet.http.HttpServletRequest,javax.servlet.http.HttpServletResponse) throws java.io.IOException
...
10:31:24,130 DEBUG org.springframework.web.servlet.mvc.method.annotation.RequestMappingHandlerMapping:1 request handler methods found on class mypackage.TestPostJSONDocumentController: {public java.lang.String mypackage.TestPostDocumentController.execute(javax.servlet.http.HttpServletRequest,javax.servlet.http.HttpServletResponse) throws java.io.IOException={[/testPostJSONDoc],methods=[POST]}}
10:31:24,130 INFO org.springframework.web.servlet.mvc.method.annotation.RequestMappingHandlerMapping:Mapped "{[/testPostJSONDoc],methods=[POST]}" onto public java.lang.String mypackage.TestPostDocumentController.execute(javax.servlet.http.HttpServletRequest,javax.servlet.http.HttpServletResponse) throws java.io.IOException

然而，当我访问其中任何一个URL时，它们会产生404个响应和日志条目，如下所示：

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'

同样的应用程序，当部署到“传统的”WAS时，也会像预期的那样工作。我想，对于自由、Eclipse下的自由或自由下的Spring，我显然缺少了一些东西。

在测试过程中的某个时候，我使用了从当前请求构建URL的代码，我看到了/webapp/gatewaymvm//resource，其中包含两个斜杠。

因此，我尝试从具有/webapp/gatewaymvm/上下文根的地方移除尾随斜杠，从而解决了这个问题。如果我将WAR直接安装在那里，则来自server.xml；如果我在EAR/Enterprise项目中安装了WAR，则来自application.xml。

有趣的是，JSP在那里使用尾斜杠，但是Spring路径没有。
