如何替换在 Groovy 中有转义的字符串？

Question

I am unable to replace the string \"@salePriceAdjId@\" which is in a file in groovy. I have googled it but found no luck.

String str = new File("C:\\example.txt").getText();

Str.replaceAll("\\"+'"'@salePriceAdjId@\\"+'"',1234567890)

You should use Groovy's regexp literals for this. Also replaceAll() doesn't mutate the str , you have to reassign:

String str = 'a vvvvvvvvvvvv \"@salePriceAdjId@\" aaaaa' // new File("C:\\example.txt").text

String val = '\\"@salePriceAdjId@\\"' // get from somewhere

str = str.replaceAll( /$val/, '1234567890')

assert str == 'a vvvvvvvvvvvv 1234567890 aaaaa'
