【问题描述】:
我正在尝试将我的 Web 应用程序更新为当前库。当我将 Spring 从 3.1.1 升级到 5.0.0 时,它开始失败:
java.lang.NoSuchMethodError: javax.servlet.http.HttpServletResponse.getStatus()I
at org.springframework.web.servlet.FrameworkServlet.publishRequestHandledEvent(FrameworkServlet.java:1083)
at org.springframework.web.servlet.FrameworkServlet.processRequest(FrameworkServlet.java:1009)

at org.mortbay.jetty.handler.ContextHandler.handle(ContextHandler.java:766)
at org.mortbay.jetty.webapp.WebAppContext.handle(WebAppContext.java:450)
我发现了两个相关的问题:
- javax.servlet.http.HttpServletResponse.getStatus() not found
- NoSuchMethodError while calling response.getStatus()
这解释了很多,我已经升级了码头和 servlet 规范。但是我的应用总是失败。

【问题讨论】:
-
Spring 5 需要 servlet 3.1 或更高版本的容器,Jetty 6 是 2.5 的容器。所以它根本行不通,你需要升级到最新的 Jetty 版本。您将需要切换到
jetty-maven-plugin而不是旧的maven-jetty-plugin。 -
你能把它写成答案吗?我现在可以启动它而不会出错。但我必须为我的 servlet 解决 404。 RequestMappingHandlerMapping 将“{[/handshake],methods=[POST],produces=[application/json;charset=UTF-8]}”映射到 public void controller.DeviceJsonController.performHandShake(java.lang.String,javax.servlet.http .HttpServletResponse) 抛出 java.io.IOException
