包路径：org.apache.log4j.Logger
类名称：Logger
方法名：error

Logger.error介绍

[英]Log a message with the ERROR level with message formatting done according to the value of messagePattern and arg parameters.

This form avoids superflous parameter construction. Whenever possible, you should use this form instead of constructing the message parameter using string concatenation.
[中]使用ERROR级别记录消息，并根据messagePattern和arg参数的值设置消息格式。
这种形式避免了超级参数构造。只要有可能，您应该使用此表单，而不是使用字符串连接构造消息参数。
