如果WebAppContext无法启动，如何取消启动或关闭jetty
[英]How to cancel start or shutdown jetty if WebAppContext fails to start
问题描述
I am using Maven Jetty Plugin, is there a way to prevent the server from starting up or shutting down (for example with maven-jetty-plugin) if ANY bean fails? 
我正在使用Maven Jetty插件，有没有办法防止服务器启动或关闭（例如使用maven-jetty-plugin）如果任何bean失败？
Here's an example: 这是一个例子：

I'd like the server to shutdown. 我想让服务器关机。 I know there's a way that involves coding the destroy method in each bean, but i'd like something global for any bean. 我知道有一种方法涉及在每个bean中编写destroy方法，但我想为任何bean提供全局的东西。

This wasn't easy to thing to accomplish. 要完成这件事并不容易。 It took few hours of hard work to find the required information from jetty's source code. 从jetty的源代码中找到所需信息需要花费几个小时的努力。
Here's the solution that worked with my simple test application that threw ServletException on HttpServlet init method. 这是与我的简单测试应用程序一起使用的解决方案，该应用程序在HttpServlet init方法上抛出ServletException。 The key to the success is to set ServletHandler's startWithUnavailable property to false. 成功的关键是将ServletHandler的startWithUnavailable属性设置为false。
pom.xml: pom.xml中：
<plugin>
<groupId>org.mortbay.jetty</groupId>
<artifactId>jetty-maven-plugin</artifactId>
<version>8.1.10.v20130312</version>
<configuration>
<contextXml>src/main/resources/context.xml</contextXml>
<webAppConfig>
<throwUnavailableOnStartupException>true</throwUnavailableOnStartupException>
</webAppConfig>
</configuration>
</plugin>
context.xml: context.xml中：
<?xml version="1.0"?>
<!DOCTYPE Configure PUBLIC "-//Mort Bay Consulting//DTD Configure//EN" "http://jetty.mortbay.org/configure.dtd">
<Configure>
<Set name="throwUnavailableOnStartupException">true</Set>
<Set name="servletHandler">
<New class="org.eclipse.jetty.servlet.ServletHandler">
<Set name="startWithUnavailable">false</Set>
</New>
</Set>
</Configure>
TestServlet.java: TestServlet.java：
public class TestServlet extends HttpServlet {
private static final long serialVersionUID = 1L;
@Override
public void init() throws ServletException {
super.init();
throw new ServletException("FAIL!");
}
@Override
protected void doGet(HttpServletRequest req, HttpServletResponse resp)
throws ServletException, IOException {
}
}

You can check org.mortbay.jetty.webapp.WebAppContext.getUnavailableException() method after org.mortbay.component.AbstractLifeCycle.start() returned. 您可以在org.mortbay.component.AbstractLifeCycle.start()返回后检查org.mortbay.jetty.webapp.WebAppContext.getUnavailableException()方法。 If it is not null, an exception was thrown in the WebAppContext initialization. 如果它不为null，则在WebAppContext初始化中抛出异常。
