Jetty：Spring 5 运行失败并出现 NoSuchMethodError

我正在尝试将我的网络应用程序更新到当前的库。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)

我发现了两个相关问题：

• 找不到 javax.servlet.http.HttpServletResponse.getStatus()
• 调用response.getStatus()时出现NoSuchMethodError

这解释了很多，我已经升级了 jetty 和 servlet 规范。但我的应用程序总是失败。

Spring 5 至少需要 Servlet 3.1 容器，但是当您使用 Jetty 6.1 时，它（最多）是 Servlet 2.5 容器。所以这显然是行不通的。

您必须升级您的 Jetty 版本。升级而不是maven-jetty-plugin您将需要使用适当的jetty-maven-plugin（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>

这应该使用插件和 Jetty 的最新版本。
