有这样一个需求，就是一个文本中，需要找出指定格式的字符串进行指定的替换，当前我的真实需求是，一个sql创建触发器的文本，我需要将所有的 包含 TB_SYS 的表名后面添加一个 “_NEW”字符串！
例如：
Creating trigger TRG_TB_SYSFILE 替换后 变成 Creating trigger TRG_TB_SYSFILE_NEW
正则表达式：(TB_SYS[^.]+)
替换表达式：$1_NEW
说明：
$0,其中$0表示正则匹配的整个最大字符串值。
$1,表示在查找的表达式中查找到的第一个（）指定的字符。
$2,表示在查找的表达式中查找到的第二个（）指定的字符。
...
$n,表示在查找的表达式中查找到的第n个（）指定的字符。
特别注意：这里替换的时候，只能手动点击一个一个替换，不能全部一次替换!!!
