本文整理了Java中org.apache.commons.lang.StringEscapeUtils.unescapeCsv()方法的一些代码示例，展示了StringEscapeUtils.unescapeCsv()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。StringEscapeUtils.unescapeCsv()方法的具体详情如下：
包路径：org.apache.commons.lang.StringEscapeUtils
类名称：StringEscapeUtils
方法名：unescapeCsv

StringEscapeUtils.unescapeCsv介绍

[英]Returns a String value for an unescaped CSV column.

If the value is enclosed in double quotes, and contains a comma, newline or double quote, then quotes are removed.

Any double quote escaped characters (a pair of double quotes) are unescaped to just one double quote.

If the value is not enclosed in double quotes, or is and does not contain a comma, newline or double quote, then the String value is returned unchanged.

see Wikipedia and RFC 4180.
[中]返回一个String值，该值用于一个未转换的CSV列。
如果该值用双引号括起来，并且包含逗号、换行符或双引号，则会删除引号。
任何双引号转义字符（一对双引号）都不会转换为一个双引号。
如果该值未包含在双引号中，或者不包含逗号、换行符或双引号，则返回的字符串值将保持不变。
见Wikipedia和{$1$}。
