方法名：put

MDC.put介绍

[英]Put a context value (the o parameter) as identified with the key parameter into the current thread's context map.

If the current thread does not have a context map it is created as a side effect.
[中]将用key参数标识的上下文值（o参数）放入当前线程的上下文映射中。
如果当前线程没有上下文映射，它将作为副作用创建。

/**
 * Put a context value (the <code>val</code> parameter) as identified with
 * the <code>key</code> parameter into the current thread's context map. The
 * <code>key</code> parameter cannot be null. Log4j does <em>not</em>
 * support null for the <code>val</code> parameter.
 * 
 * <p>
 * This method delegates all work to log4j's MDC.
 * 
 * @throws IllegalArgumentException
 *             in case the "key" or <b>"val"</b> parameter is null
