关于JBoss的Log4j的输出问题

使用Web应用中的Log4j配置，而非使用JBoss自身的Log4j配置，具体修改如下：1、修改log4j.xml文件添加<appender-ref ref="fileAppender" />，修改为<logger name="com.travelsky.pss"> <level value="info" /> <appender-ref ref="fileAppender" /></logger>其余<logger name="org.springframework"> 和<logger name="org.hibernate"> 可酌情修改。将<root>中的内容注释掉。生成的log日志以\jboss-eap-5.0\jboss-as\bin\为根目录2、修改web.xml文件增加下面配置 <servlet> <servlet-name>Log4jInit</servlet-name> <servlet-class>com.travelsky.pss.abframe.base.log.Log4jInit</servlet-class> <init-param> <param-name>log4j-init-file</param-name> <param-value>/WEB-INF/classes/log4j.xml</param-value> </init-param> <load-on-startup>1</load-on-startup> </servlet><load-on-startup>中的值如果为2，在Tomcat下正常启动，但JBoss会启动报错。3、增加Log4j的初始化类Log4jInit

public class Log4jInit extends HttpServlet {

private static final long serialVersionUID = 1L;

/**

     * 初始化Log4j的配置

     * @param 

     * Date: 2012-5-15上午10:40:49

     */

public void init() {

String prefix = getServletContext().getRealPath("/");

String file = getInitParameter("log4j-init-file");

if (file != null) {

DOMConfigurator.configure(prefix + file);

//this.listCofig();   // 调试用

}

}

private void listCofig() {

LoggerRepository logRp = org.apache.log4j.LogManager

.getLoggerRepository();

Logger root = logRp.getRootLogger();

showLogger(root);

Enumeration<?> enumeration = logRp.getCurrentLoggers();

if (enumeration != null) {

while (enumeration.hasMoreElements()) {

Logger log = (Logger) enumeration.nextElement();

showLogger(log);

}

}

}

private void showLogger(Logger log) {

Enumeration<?> enumeration = log.getAllAppenders();

if (enumeration != null && enumeration.hasMoreElements()) {

System.out.println(">>>log name():" + log.getName());

while (enumeration.hasMoreElements()) {

Appender append = (Appender) enumeration.nextElement();

System.out.println(" append ref.getName():" + append.getName());

}

System.out.println(">>>log name end");

}

}

}
