我正在使用 Maven Jetty 插件，如果任何 bean 失败，有没有办法阻止服务器启动或关闭（例如使用 maven-jetty-plugin）？

这是一个例子：

我想关闭服务器。我知道有一种方法涉及对每个 bean 中的 destroy 方法进行编码，但我希望任何 bean 都具有全局性。

这不是一件容易的事情。从 jetty 的源代码中找到所需的信息需要几个小时的艰苦工作。

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 初始化方法上抛出了 ServletException。成功的关键是将 ServletHandler 的 startWithUnavailable 属性设置为 false。

pom.xml：

<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>

上下文.xml：

<?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：

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 {
    }
}

您可以在返回后检查org.mortbay.jetty.webapp.WebAppContext.getUnavailableException()方法。org.mortbay.component.AbstractLifeCycle.start()如果不为 null，则在WebAppContext初始化时引发异常。
