我正在为嵌入式Jetty 9.4.3.x服务器编写POC。当我使用多个处理程序运行服务器时,只有第一个处理程序工作。在代码中如果我有'context'作为第一个处理程序,我的hello servlet工作,对于jsp我得到404错误。如果我有'webapp'作为第一个处理程序,jsp工作,我得到一个404 for servlet。这是代码。我错过了什么吗? servlet和jsp文件是简单的测试文件。如果需要,我可以添加webdefault.xml和jetty.xml文件。

答案 0 :(得分:1)
同一ServletContextHandler
上有WebAppContext
和contextPath
这两种情况都不起作用。
将它们合并在一起。
ServletContextHandler
上只有WebAppContext
或contextPath("/")
