java - 嵌入式 jetty - 503

标签 java embedded-jetty http-status-code-503

我从 https://www.eclipse.org/jetty/documentation/current/embedded-examples.html#embedded-one-webapp 开始

然后尝试了这个 Add web application context to Jetty 但我仍然得到 503。

我创建了一个简单的index.html用于测试...

<html>
<head>
</head>
<body>
Nothing to see here!
</body>
</html>

我的代码是...

public class WebTest {

    public static void main(String args[]) {

        Server server = new Server(8080);

        WebAppContext webapp = new WebAppContext();
        webapp.setContextPath("/test");
        webapp.setResourceBase("D:\\testProject\\src\\main\\webapp");
        webapp.setDescriptor("D:\\testProject\\src\\main\\webapp\\WEB-INF\\web.xml");
        webapp.setParentLoaderPriority(true);

        server.setHandler(webapp);
        try {
            server.start();
            server.join();
        } catch (Exception ex) {
            ex.printStackTrace();
        }
    }
}

以及控制台摘录...

最佳答案

转储显示...

o.e.j.w.WebAppContext@1372ed45{/test,file:///D:/testProject/src/main/webapp/,UNAVAILABLE} - STARTED

这表明您位于 /test 的 Web 应用程序已启动，但最终处于“不可用”状态。

这就是为什么你会收到 503 错误，如果上下文被标记为 UNAVAILABLE，Jetty Server 将响应 503。 (甚至从未尝试与您的网络应用程序进行通信)

接下来，我们需要注意 Web 应用程序的启动日志记录，在 Web 应用程序的部署和/或初始化阶段，某些内容引发了错误。

首次升级到更现代的 Jetty 9.4.x 版本，您的 9.4.8 很旧，并且还存在多个已知漏洞。请使用9.4.18.v20190429。

我看到一些非 jetty jar，因此您可能需要设置多个日志记录框架才能与您的 slf4j-api 层一起使用。

添加Java Util Logging to Slf4J bridge至少(捕获 jsf 和 el 层)。然后处理 OSGi 日志记录，最后处理 j2mod、jSerialComm 和 eclipse-kura 库与 slf4j 类似的桥使用的任何日志记录。
