Add web application context to Jetty
提问by mikhail
I want to create simple Spring MVC "Hello world" application that runs under Jetty (wich is a part of application).
我想创建在 Jetty 下运行的简单 Spring MVC“Hello world”应用程序（这是应用程序的一部分）。
Structure of my application is:
我的应用程序的结构是：
|-WEB-INF
| |-view
| |-layout
| |-index.jsp
| |-web.xml
|
|-jetty.xml
|-application-context.xml
I try to create Jetty server and add web application context based on web.xml file:
我尝试创建 Jetty 服务器并基于 web.xml 文件添加 web 应用程序上下文：
Resource jettyConfig = Resource.newSystemResource("jetty.xml");
XmlConfiguration configuration = new XmlConfiguration(jettyConfig.getInputStream());
Server server = (Server)configuration.configure();
WebAppContext wac = new WebAppContext();
wac.setDescriptor("WEB-INF/web.xml");
wac.setContextPath("/");
wac.setParentLoaderPriority(true);
server.setHandler(wac);
server.start();
Server starts fine, but without my context: no info about spring start up in logs, spring mvc controllers are not available. Have anybody ideas what I do wrong?
服务器启动正常，但没有我的上下文：日志中没有关于 spring 启动的信息，spring mvc 控制器不可用。有人知道我做错了什么吗？

If you are running with an exploded war directory try setting the resource base property explicitly:
如果您使用分解的 war 目录运行，请尝试显式设置资源库属性：
context.setResourceBase("/path-to-your-project/WebContent");
context.setDescriptor("/path-to-your-project/WebContent/WEB-INF/web.xml");
or if you are deploying the war itself you can just use:
或者，如果您要部署War本身，则可以使用：
context.setWar("/path-to-your-project/WebContent");
Here are the docs showing embedded Jetty samples.
以下是显示嵌入式 Jetty 示例的文档。
In the context of your app:
在您的应用程序上下文中：
Resource jettyConfig = Resource.newSystemResource("jetty.xml");
XmlConfiguration configuration = new XmlConfiguration(jettyConfig.getInputStream());
Server server = (Server)configuration.configure();
WebAppContext wac = new WebAppContext();
wac.setResourceBase(".");
wac.setDescriptor("WEB-INF/web.xml");
wac.setContextPath("/");
wac.setParentLoaderPriority(true);
server.setHandler(wac);
server.start();
This assumes that your base path where you're running your server from is the same as the path to the web content.
这假设您运行服务器的基本路径与 Web 内容的路径相同。

The application-context.xml file should be placed inside the WEB-INF directory.
application-context.xml 文件应该放在 WEB-INF 目录中。
