How to get lastIndex in Thymeleaf
0
In my application, I have to extract a file name from its path. I want to get the last index of '/' to extract the file name. But I have not seen any #strings function for lastIndex.
The file name has a prefix of a number and -. If I use ${#strings.substringAfter(string, '-' )}, I get the file name but not the number pdefix. Please suggest.

You can use the arraySplit function that belongs to #strings and get the last array's element using the #arrays.length method.
Something like this:
${#strings.arraySplit(yourString, '/')[#arrays.length(#strings.arraySplit(yourString, '/')) - 1]}
I didn't test the code but it should work.

excellent stuff. It works perfectly. I am also trying to get the number before the underscore using substringBefore but without success. th:text="${#strings.substringBefore(#strings.arraySplit(file, '/')[#arrays.length(#strings.arraySplit(file, '/')) -1]), '_'}"

So, do a newarraySplit(${#strings.arraySplit(yourString, '/')[#arrays.length(#strings.arraySplit(yourString, '/')) - 1]} , '_')[0]and get the first array's element.

th:text="${#strings.arraySplit({#strings.arraySplit(myString, '/')[#arrays.length(#strings.arraySplit(myString, '/')) - 1]}, '_')[0]}" I am getting the number but it is coming as [23 instead of 23
