web服务处理程序防止log4j2配置

2016-07-27 56 views

环境： JDK 7中，WebLogic 12.1.3.0服务器（贴片3） Maven构建系统web服务处理程序防止log4j2配置

大厦Maven的，我具有取决于一个一个web服务WAR模块定义web服务处理程序的第二个JAR模块。 Webservice模块具有一个上下文侦听器，该侦听器稍后应该从数据库初始化log4j2（循环）。 没有在任何地方定义log4j2.xml，也不需要。

问题是，当通过在webservice端点上使用@HandlerChain批注启用处理程序时，log4j2配置在Web服务上下文侦听器初始化之前会损坏。

模块DemoWebService：

@WebService(endpointInterface = "demo.IDemoWebService") 
@HandlerChain(file = "handlers.xml") 
public class DemoWebService implements IDemoWebService { 
... 
} 

public class DemoServletContextListener implements ServletContextListener { 

    /** Status Logger */ 
    private static final Logger LOG = StatusLogger.getLogger(); 

    @Override 
    public void contextInitialized(ServletContextEvent event) { 
     System.out.println("Demo listener context intialized"); 
     System.out.println(LOG.getLevel() + " - " + LOG.isDebugEnabled() + " - " + LOG.isInfoEnabled() + " - " + LOG.isWarnEnabled()); 

     LOG.info("LOG Demo listener context intialized"); 
    } 

    @Override 
    public void contextDestroyed(ServletContextEvent event) { 
     System.out.println("Demo listener context destroyed"); 
     LOG.info("LOG Demo listener context destroyed"); 
    } 
}

的web.xml

<?xml version="1.0" encoding="UTF-8"?> 
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/javaee" 
xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" version="2.5"> 

    <display-name>DemoWebService</display-name> 

    <!-- log4j2 configuration --> 
    <context-param> 
     <param-name>isLog4jAutoInitializationDisabled</param-name> 
     <param-value>true</param-value> 
    </context-param> 

    <listener> 
     <listener-class>demo.DemoServletContextListener</listener-class> 
    </listener> 

    ... 
</web-app>

handlers.xml

<?xml version="1.0" encoding="UTF-8"?> 
<handler-chains xmlns="http://java.sun.com/xml/ns/javaee"> 
    <handler-chain> 
     <handler> 
      <handler-name>Performance</handler-name> 
      <handler-class>demo.wshandler.WebServiceDemoHandler</handler-class> 
     </handler> 
    </handler-chain> 
</handler-chains>

模块wshandler：

public class WebServiceDemoHandler { 

    private static Logger log = LogManager.getLogger(WebServiceDemoHandler.class); 

    @Override 

    public boolean handleMessage(SOAPMessageContext context) { 
     log.info("something"); 
     return true; 
    } 

    @Override 
    public boolean handlingNotRequired() { 
     return false; // this handler always handles the message 
    } 
}

现在，当我在部署过程中比较服务器日志一次当@HandlerChain（文件=“handlers.xml”）是活动的，有一次，当注释掉，在日志中的差异基本上下列行：

处理程序链未激活：

Demo listener context intialized 
TRACE - true - true - true 
INFO StatusLogger LOG Demo listener context intialized

这里发生的事情，是我想Java的类加载器变得活跃 Web上下文监听器之前，然后触发log4j2，不需要初始化。这会导致不可恢复的损坏log4j2配置，并且所有其他日志都将丢失。

的答案贴出的问题很简单，包括为类DemoServletContextListener行

StatusLogger.getLogger().reset();

和StatusLogger将再次合作。 但是，损坏的整体logj4配置不能像这样解决。然而，这里省略了初始化代码，因此最多只是另一个帖子的主题 -

或者如果你不在处理程序本身中使用log4j，可能太早 –

您是否尝试过将LOG StatusLogger字段声明为非静态的DemoServletContextListener？加载该类将导致Log4j2自行初始化。

如果你想推迟Log4j2的初始化，直到加载了WebServiceDemoHandler，那么根本不应该在DemoServletContextListener中使用StatusLogger。

另外，查看状态记录器输出的前两行，有两个类加载器，第一个（[email protected]）开始初始化Log4j2。

还有一个[email protected] finder: [email protected] annotation: [email protected]类加载器，显然不起作用。根据名称，该第二个类加载器用于Web应用程序。我想你想让Log4j2被第二个类加载器初始化。不确定第一个类加载器来自哪里，但这可能是进一步调查的好主角。

嗨Remko！非常感谢主管的答复。 是的，我试过并将WebServiceDemoHandler中的Logger定义为非静态的。它没有帮助。 什么帮助只是没有在第二个模块wshandler中使用log4j2。 我可以通过添加以下行来让StatusLogger再次在DemoServletContextListener中工作 StatusLogger.getLogger（）。reset（）; 但是，上下文侦听器中应该发生的整体日志配置无法保存。 （为简洁起见，上下文侦听器中的日志初始化代码被省略了。） –

不客气！希望它有助于解决这个谜团。 –
