java - 初始化上下文时不会调用 ServletContextListener.contextInitialized

Question

我正在创建一个 war 文件 (progressReporter.war) 并将其部署在 Jetty7.2.2.v20101205 上。我在 contextInitialized 方法上有一个系统输出，我应该在 jetty 启动时看到它。我开始使用
jetty java -jar 开始.jar

Java版本是1.6

同样的事情，当我在 tomcat 上运行时，它运行得非常好。对于 jetty ，我已经包括在内

• jetty-client-7.2.2.v20101205.jar
• jetty-continuation-7.2.2.v20101205.jar
• jetty -http-7.2.2.v20101205.jar
• jetty-io-7.2.2.v20101205.jar
• jetty-servlets-7.2.2.v20101205.jar
• jetty-util-7.2.2.v20101205.jar

下面是我的内容

@Override  
public void contextInitialized(ServletContextEvent servletContextEvent) {  
    ApplicationContext applicationContext = new ClassPathXmlApplicationContext(new String[] {"spring-http-config.xml", "test-spring-http-config.xml", "spring-ibatis.xml" });  
    System.out.println("setting attribute now ............... " + servletContextEvent.getServletContext());  
}  

以下是我在 web.xml 中的内容

<listener>  
    <listener-class>org.springframework.web.context.ContextLoaderListener  
    </listener-class>  
    <listener-class>com.client.BatchProgressorContextListener  
   </listener-class>  
</listener>

你能帮我看看这里出了什么问题吗？

以下是我启动jetty时的输出:

你能帮我看看我做错了什么以及需要做什么才能在 Jetty 上运行吗？如果您还需要任何其他详细信息，请务必告诉我。

提前致谢。

Answer 1

一些事情:

• 我在日志中看到上下文正在上升:

3   [main] INFO  org.springframework.beans.factory.xml.XmlBeanDefinitionReader

- Loading XML bean definitions from class path resource [spring-http-config.xml ] 203 [main] INFO org.springframework.beans.factory.xml.XmlBeanDefinitionReader - Loading XML bean definitions from class path resource [test-spring-http-confi g.xml] 218 [main] INFO org.springframework.beans.factory.xml.XmlBeanDefinitionReader - Loading XML bean definitions from class path resource [spring-ibatis.xml]

所以您的代码可以正常工作。

• 您写入控制台而不是写入日志文件。可能这就是你看不到它的原因。尝试使用 commons-logging 来记录您的消息。

• 为什么在 web.xml 中同时有 ContextLoaderListener 和 BatchProgressorContextListener？ (我假设 BatchProgressorContextListener 是你在帖子开头给出的代码，对吧？)可能您只需要一个上下文监听器来加载您的上下文，而 ContextLoaderListener 就足够了。从 web.xml 中删除 BatchProgressorContextListener 并改为添加

 <context-param>
    <param-name>contextConfigLocation</param-name>
    <param-value> 
       classpath:spring-http-config.xml
       classpath:test-spring-http-config.xml
       classpath:spring-ibatis.xml
    </param-value>
</context-param>
