本文整理了Java中org.apache.logging.log4j.message.Message.getFormattedMessage()方法的一些代码示例，展示了Message.getFormattedMessage()的具体用法。这些代码示例主要来源于Github/Stackoverflow/Maven等平台，是从一些精选项目中提取出来的代码，具有较强的参考意义，能在一定程度帮忙到你。Message.getFormattedMessage()方法的具体详情如下：
包路径：org.apache.logging.log4j.message.Message
类名称：Message
方法名：getFormattedMessage

Message.getFormattedMessage介绍

[英]Gets the Message formatted as a String. Each Message implementation determines the appropriate way to format the data encapsulated in the Message. Messages that provide more than one way of formatting the Message will implement MultiformatMessage.

When configured to log asynchronously, this method is called before the Message is queued, unless this message implements ReusableMessage or is annotated with AsynchronouslyFormattable. This gives the Message implementation class a chance to create a formatted message String with the current value of any mutable objects. The intention is that the Message implementation caches this formatted message and returns it on subsequent calls. (See LOG4J2-763.)

When logging synchronously, this method will not be called for Messages that implement the StringBuilderFormattable interface: instead, the StringBuilderFormattable#formatTo(StringBuilder) method will be called so the Message can format its contents without creating intermediate String objects.
[中]获取格式化为字符串的消息。每个消息实现都决定了格式化消息中封装的数据的适当方式。提供多种格式化方式的消息将实现多格式消息。
配置为异步日志时，在消息排队之前调用此方法，除非此消息实现ReusableMessage或使用AsynchronouslyFormattable注释。这使消息实现类有机会使用任何可变对象的当前值创建格式化的消息字符串。其目的是消息实现缓存这个格式化的消息，并在后续调用中返回它。（见LOG4J2-763。）
同步记录时，对于实现StringBuilderPerformAttable接口的消息，将不会调用此方法：相反，将调用StringBuilderPerformAttable#formatTo（StringBuilder）方法，以便消息可以格式化其内容，而无需创建中间字符串对象。
