我有一个大字符串，需要在一行中基于“ - ”拆分成段落，下面是字符串

我已经在很多方面使用过分裂而且没有一个工作

以下是我用过的一些。

split("\n--\n");
split("^\\s");
split("\\n--\\n")

他们都没有工作

Answer 1

使用此正则表达式：(?m)^--$\R?

(?m)启用多线模式
^匹配行的开头
--匹配字符--
$匹配行尾
\R?可选择匹配换行符

即。匹配一行只包含两个短划线（-）字符，包括结束该行的换行符（如果存在）。

作为Java代码，即：

String[] paragraphs = input.split("(?m)^--$\\R?");

请参阅IDEONE以获取证明。

Java将字符串拆分为
