如何将java.util.logging发送到log4j2?

问题描述

我正在处理一个使用 NetBeans 平台的项目.在底层，NetBeans使用 java.util.logging 框架.

I'm working on a project that uses the NetBeans Platform. Under the hood, NetBeans uses the java.util.logging framework.

我想通过将 java.util.logging 绑定到 log4j2 来拦截这些日志调用.这可能吗?

I would like to intercept these log calls by binding java.util.logging to log4j2. Is this possible?

已经问过类似的先前问题，但特定于 log4j 而不是 log4j2 ！

Previous questions have been asked that are similar, but were specific to log4j and not log4j2!

推荐答案

我找到了一个解决方案:

I've found a solution:

NetBeans平台以 org.netbeans.* 命名空间命名记录器.要路由NetBeans日志调用，我只需创建一个 Handler 并将其注册到 org.netbeans 记录器中即可.

The NetBeans Platform names logger after the org.netbeans.* namespace. To route NetBeans log calls, I simply created a Handler and registered it with the org.netbeans logger:

public class CustomHandler extends Handler
{
    @Override
    public void publish(LogRecord record)
    {
        // Re-direct log calls here (e.g. send record to Log4j2 logger).
    }

    @Override
    public void flush()
    {
    }

    @Override
    public void close() throws SecurityException
    {
    }
}

请确保注册新的 Handler 并在必要时禁用父记录器:

Be sure to register the new Handler and disable parent loggers if necessary:

Logger logger = Logger.getLogger("org.netbeans");
logger.addHandler(new CustomerHandler());
logger.setUseParentHandlers(false);
