我正在尝试将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,它因以下原因而开始失败:
java.lang.NoSuchMethodError: javax.servlet.http.HttpServletResponse.getStatus()I

我发现了两个相关的问题:
解释了很多,我已经升级了码头和servlet规范。但是我的应用程序不断失败。

Spring 5至少需要一个Servlet 3.1容器,但是当您使用Jetty 6.1时(最多)是Servlet 2.5容器。因此,这显然是行不通的。
您将必须升级您的Jetty版本。要升级而不是升级,maven-jetty-plugin
您将需要使用适当jetty-maven-plugin
的名称(名称已更改),并且它现在是Eclipse的一部分。
<maven-jetty-plugin.version>9.4.7.v20170914</maven-jetty-plugin.version>
<plugin>
<groupId>org.eclipse.jetty</groupId>
<artifactId>jetty-maven-plugin</artifactId>
<version>${maven-jetty-plugin.version}</version>
</plugin>
这应该同时使用插件和Jetty的最新版本。
