如何仅在log4j中从当前线程获取日志

Question

I want to intercept logs from the specific thread in my application for the certain period of time. I'm using log4j. The code below does that, but I'm getting logs from others threads too.

                WriterAppender appender = new WriterAppender(new PatternLayout("%d{ISO8601} %p - %m%n"), consoleWriter);

                appender.setName("STR_APPENDER");
                appender.setThreshold(org.apache.log4j.Level.INFO);
                Logger.getRootLogger().addAppender(appender); 
                //Some Logic here (I'm using other classes and jars here and I want to get this logs as well)
                Logger.getRootLogger().removeAppender("STR_APPENDER");

I'm aware that Logger.getRootLogger() is not a good solution here, but I don't have any other idea.

You can use MDC.put.

eg

MDC.put("threadName",Thread.currentThread().getName());

Using that you can put thread name.

Using Log4j appender you can print the thread name [%X{threadName} in logs
