我在尝试使用了Servlet 3.0编程的方式来注册使用的Jetty Maven插件运行servlet得到一个Spring 3.1框架的web应用的问题。码头8 Maven插件码头：运行战争没有检测WebApplicationInitializer
这里是我的Maven插件定义（指定具有默认的servlet映射删除一个覆盖webdefault.xml）：
<plugin>
<groupId>org.mortbay.jetty</groupId>
<artifactId>jetty-maven-plugin</artifactId>
<version>8.1.1.v20120215</version>
<configuration>
<systemProperties>
<systemProperty>
<name>DEBUG</name>
<value>TRUE</value>
</systemProperty>
</systemProperties>
<scanIntervalSeconds>0</scanIntervalSeconds>
<webAppConfig>
<defaultsDescriptor>src/main/resources/webdefault.xml</defaultsDescriptor>
</webAppConfig>
<stopPort>9966</stopPort>
<stopKey>foo</stopKey>
</configuration>
</plugin>
这是我切下来的webapp：
public class GcpWebApplicationInitializer implements WebApplicationInitializer {
public void onStartup(ServletContext servletContext) throws ServletException {
AnnotationConfigWebApplicationContext root =
new AnnotationConfigWebApplicationContext();
root.scan();
servletContext.addListener(new ContextLoaderListener(root));
ServletRegistration.Dynamic servlet = servletContext.addServlet("TESTSERVLET", new DispatcherServlet(root));
servlet.setLoadOnStartup(1);
servlet.addMapping("/");
}
}
的commannd线我用这个运行起来的是：
mvn -U clean package jetty:run-war
用下面的输出（只是run-war par T）：

正如你可以看到它检测到春天的servlet SpringServletContainerInitializer但这个servlet未检测到GcpWebApplicationInitializer。但是，如果我拿起war文件并手动将其置于独立的Jetty下，它将检测到GcpWebApplicationInitializer。

另外，如果我用 MVN -U清洁套装码头：运行 那么它也将检测GcpWebApplicationInitializer，因为它应该。
那么，为什么码头：运行战争行为不如我所料？最初我以为这是造成这个问题的码头插件，但现在我认为它更像是Spring问题或类路径问题。
我试着在我的IDE来调试这一点，它与上SpringServletContainerInitializer.onStartup断点（）调用码头：运行在经过与它在我的servlet类设置正确的webAppInitializerClasses。码头：运行战争在同一断点没有webAppInitializerClasses在通过它的码头调用此方法，因此它肯定看起来像Jetty是不处理的@HandlesTypes（WebApplicationInitializer.class）注释。 – 2012-03-17 04:19:47
同样在我的webdefault.xml中，我也尝试将metadata-complete设置为false - 这没有帮助。我也尝试将web_app_2_5.xsd提升到web_app_3_0.xsd，但仍然没有帮助。 – 2012-03-17 04:23:16
