基于 Java 的 Spring WebApp 未运行 Jetty9

Question

我有一个基于Java的Spring配置(没有web.xml)的war项目，它在mvn jetty:run上完美运行，但是当我将Jetty 9放入机器中时，该项目没有运行。 jetty 9 服务器运行，但应用程序根本没有初始化。

该应用程序包含一个队列订阅者。

看来我需要一个 web.xml 文件。

有人知道我缺少什么吗？

Jetty 9 服务器上应用程序的 xml 配置文件是(编辑:使用正确的 conf 文件)

<?xml version="1.0"?>

jetty 控制台日志是

编辑:xml 配置文件现在是正确的，我必须取消注释 ${jetty.home}/start.ini

中的上述选项

# ===========================================================
# Enable additional webapp environment configurators 
# -----------------------------------------------------------
OPTIONS=plus
etc/jetty-plus.xml

# ===========================================================

Answer 1

首先要解决一些明显的问题。

1. 您使用的是 Java 8，请升级到 Jetty 9.2.6(Jetty 9.0.3 太旧，不能很好地支持 Java 8)
2. 您的 DTD 引用有问题，它来自 Jetty 7，已知它会在 Jetty 9 中导致问题。 使用<!DOCTYPE Configure PUBLIC "-//Jetty//Configure//EN" "http://www.eclipse.org/jetty/configure_9_0.dtd">相反。
3. 您的类引用错误，应该修复。 "org.eclipse.jetty_runˆy.server.Server"不存在
