找不到 javax.servlet.http.HttpServletResponse.getStatus()

Question

我正在使用嵌入式 Jetty 服务器，部署 Jersey REST api，我正在尝试使用 log4J 记录错误。当发生错误时，例如找不到 URL，并且控制台日志显示以下错误:

和服务器初始化代码:

ServletContextHandler servletContextHandler = new ServletContextHandler();
ResourceConfig resourceConfig = new ResourceConfig();
resourceConfig.register(MultiPartFeature.class);
resourceConfig.register(GsonMessageBodyHandler.class);
resourceConfig.register(PrivateAPI.class);
resourceConfig.register(MalformedURLExceptionMapper.class);
ServletContainer sc = new ServletContainer(resourceConfig);
ServletHolder holder = new ServletHolder(sc);
servletContextHandler.addServlet(holder, "/*");


Server server = new Server(new InetSocketAddress(args[0], Integer.parseInt(args[1])));
HandlerCollection handlerCollection = new HandlerCollection();

handlerCollection.setHandlers(new Handler[] {servletContextHandler, new RequestLogHandler(), new DefaultHandler()});
server.setHandler(handlerCollection);
server.start();
server.join();

Answer 1

您的项目中有一个非常古老的 servlet-api jar。

javax.servlet.http.HttpServletResponse#getStatus()在 Servlet 3.0 中加入

添加以下内容:

<dependency>
  <groupId>javax.servlet</groupId>
  <artifactId>javax.servlet-api</artifactId>
  <version>3.1.0</version>
</dependency>

转储您的依赖项并验证您没有存在多个版本的 servlet-api jar(这很常见，因为 servlet-api jar 的 maven 坐标空间在过去 10 年中发生了几次变化)

$ mvn dependency:tree
