如何将HornetQ日志记录委派给Slf4j

Question

我希望从我的应用程序中嵌入的HornetQ的所有日志记录委托给slf4j.不幸的是,任何尝 我已经尝试过了

• 添加了jul-to-slf4j
• 安装了这座桥 SLF4JBridgeHandler.install();
• 试过Log4jLogDelegateFactory("hornetq-configuration.xml"经过<log-delegate-factory-class-name>org.hornetq.integration.logging.Log4jLogDelegateFactory</log-delegate-factory-class-name>)
• 写我自己LogDelegate和LogDelegateFactory

但无论我做什么,下面的线路都没有抓住:

13.07.2011 17:42:11 org.hornetq.core.logging.impl.JULLogDelegate warn
WARNUNG: AIO wasn't located on this platform, it will fall back to using pure Java NIO. If your platform is Linux, install LibAIO to enable the AIO journal
13.07.2011 17:42:11 org.hornetq.core.logging.impl.JULLogDelegate info
INFO: Using NIO Journal
13.07.2011 17:42:11 org.hornetq.core.logging.impl.JULLogDelegate info
INFO: Started Netty Acceptor version 3.1.5.GA-r1772

我错过了什么？

我找到了一个完整的解决方案,我想与您分享.我之前已经尝试过这些,但你必须结合其他答案中提到的一些技巧.

• 你需要编写自己的LogDelegate:

import org.hornetq.spi.core.logging.LogDelegate;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
public class Slf4jLogDelegate implements LogDelegate {
    private final Logger logger;
    public Slf4jLogDelegate(Class clazz) {
        logger = LoggerFactory.getLogger(clazz);
    }
    @Override
    public void debug(Object message) {
        logger.debug(message.toString());
    }
    @Override
    public void debug(Object message, Throwable t) {
        logger.debug(message.toString(), t);
    }
    @Override
    public void error(Object message) {
        logger.error(message.toString());
    }
    @Override
    public void error(Object message, Throwable t) {
        logger.error(message.toString(), t);
    }
    @Override
    public void fatal(Object message) {
        logger.error(message.toString());
    }
    @Override
    public void fatal(Object message, Throwable t) {
        logger.error(message.toString(), t);
    }
    @Override
    public void info(Object message) {
        logger.info(message.toString());
    }
    @Override
    public void info(Object message, Throwable t) {
        logger.info(message.toString(), t);
    }
    @Override
    public boolean isDebugEnabled() {
        return logger.isDebugEnabled();
    }
    @Override
    public boolean isInfoEnabled() {
        return logger.isInfoEnabled();
    }
    @Override
    public boolean isTraceEnabled() {
        return logger.isTraceEnabled();
    }
    @Override
    public void trace(Object message) {
        logger.trace(message.toString());
    }
    @Override
    public void trace(Object message, Throwable t) {
        logger.trace(message.toString(), t);
    }
    @Override
    public void warn(Object message) {
        logger.warn(message.toString());
    }
    @Override
    public void warn(Object message, Throwable t) {
        logger.warn(message.toString(), t);
    }
}

• 然后你需要写工厂:

import org.hornetq.spi.core.logging.LogDelegate;
import org.hornetq.spi.core.logging.LogDelegateFactory;
public class Slf4jLogDelegateFactory implements LogDelegateFactory {
    // Maybe caching of delegates makes sense?
    @Override
    public LogDelegate createDelegate(Class clazz) {
        return new Slf4jLogDelegate(clazz);
    }
}

• 然后在你的hornetq-configuration.xml中添加以下行: <log-delegate-factory-class-name>yourpackage.Slf4jLogDelegateFactory</log-delegate-factory-class-name>
• 最后,在启动嵌入式服务器之前添加以下行: org.hornetq.core.logging.Logger.setDelegateFactory(new Slf4jLogDelegateFactory());

我只是想知道为什么他们不能使用经过验证的记录机制,这使得交换记录器变得容易.
