log4j2 - Log4j2 不通过附加程序记录 Faces 异常

Question

我有一个带有不同应用程序的tomcat服务器，每个都有它自己的log4j2附加程序，它记录到它自己的文件中，每个java类都正确记录它的异常，以及JSF异常，例如未关闭的标签、错误的类/方法/我制作的属性名称一个记录 FacesExceptions 的 defaultexceptionhandler，但由于某种原因我找不到它根本没有记录。

这是环境 Ubuntu 18.04 和 16.04 的规格（以防万一）tomcat 8.0.47 oracle jdk 1.8.0_181 myfaces 2.3.1 log4j2 2.11.0

所以问题是，即使在通过打开标签等方式强制异常来调试 handle() 时，它确实会到达 logger.error() 调用上的断点，但它只是不会附加到文件中。

这是该项目的 faces-config.xml 中的处理程序声明（我保留了所有导航案例和其他垃圾，到目前为止所有这些都有效，如果需要，我将全部编辑）

    <faces-config version="2.0"
                      xmlns="http://java.sun.com/xml/ns/javaee" 
                      xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
                      xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-facesconfig_2_0.xsd">

        <factory>
            <exception-handler-factory>
                gescoweb.tools.DefaultExceptionHandlerFactory
            </exception-handler-factory>
        </factory>       

    </faces-config>

这是 DefaultExceptionHandler.java

package gescoweb.tools;

import java.util.Iterator;
import javax.faces.FacesException;
import javax.faces.context.ExceptionHandler;
import javax.faces.context.ExceptionHandlerWrapper;
import javax.faces.context.FacesContext;
import javax.faces.event.ExceptionQueuedEvent;
import org.apache.log4j.LogManager;
import org.apache.log4j.Logger;

/**
 *
 */
public class DefaultExceptionHandler extends ExceptionHandlerWrapper {

    private ExceptionHandler wrapped;

    public static final Logger LOGGER = LogManager.getLogger("gescoweb");

    public DefaultExceptionHandler(ExceptionHandler wrapped) {
        this.wrapped = wrapped;
    }

    @Override
    public ExceptionHandler getWrapped() {
        return this.wrapped;
    }

    /** Recibe la lista de excepciones y las procesa según su tipo.
     * @throws FacesException 
     */
    @Override
    public void handle() throws FacesException {
        for (Iterator<ExceptionQueuedEvent> i = getUnhandledExceptionQueuedEvents().iterator(); i.hasNext();) {
            Throwable t = i.next().getContext().getException();
            if (t != null) {
                LOGGER.error("Error inesperado.", new Exception(t));
            } else {
                LOGGER.error("", new Exception(t));
            }
        }
        getWrapped().handle();
    }

    /**
     * Tratamiento especial de otras excepciones.
     * @param facesContext
     * @param t
     * @return 
     */
    protected String handleUnexpected(FacesContext facesContext, final Throwable t) {
        if (t instanceof IllegalStateException) {
            return "key.exception.IllegalStateException";
        } else {
            super.handle();
            return "";
        }
    }
}

这是处理程序工厂

package gescoweb.tools;

import javax.faces.context.ExceptionHandler;
import javax.faces.context.ExceptionHandlerFactory;

/**
 *
 */
public class DefaultExceptionHandlerFactory extends ExceptionHandlerFactory {

    private ExceptionHandlerFactory parent;

    public DefaultExceptionHandlerFactory(ExceptionHandlerFactory parent) {
        this.parent = parent;
    }

    /**
     * Crea los handlers modificados.
     *
     * @return
     */
    @Override
    public ExceptionHandler getExceptionHandler() {
        ExceptionHandler eh = parent.getExceptionHandler();
        eh = new DefaultExceptionHandler(eh);
        return eh;

    }
}   

最后这是 log4j2.xml 配置文件

没关系，我在 DefaultExceptionHandler 中导入了错误的 log4j 库，将导入更改为

import org.apache.logging.log4j.LogManager;
import org.apache.logging.log4j.Logger;

现在一切正常......
