包路径：java.util.regex.Matcher
类名称：Matcher
方法名：appendReplacement

Matcher.appendReplacement介绍

[英]Appends a literal part of the input plus a replacement for the current match to a given StringBuffer. The literal part is exactly the part of the input between the previous match and the current match. The method can be used in conjunction with #find() and #appendTail(StringBuffer) to walk through the input and replace all occurrences of the Pattern with something else.
