我使用Maven插件码头，是有办法，以防止启动或关闭（例如使用Maven的码头，插件）任何豆失败的服务器？

下面是一个例子：

我想服务器关闭。 我知道有这涉及到编码每个bean的destroy方法的一种方式，但我想的东西全球任何豆。

Answer 1:

这是不容易做到的事情。 花了艰苦的工作几个小时才能找到码头的源代码所需的信息。

这里是与抛出的ServletException上的HttpServlet init方法我简单的测试应用程序工作的解决方案。 对成功的关键是ServletHandler的startWithUnavailable属性设置为false。

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： 

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 {
    }
}


Answer 2:

您可以检查org.mortbay.jetty.webapp.WebAppContext.getUnavailableException()之后方法org.mortbay.component.AbstractLifeCycle.start()返回。 如果不为空，异常在被抛出WebAppContext初始化。
