You're using double quotes around your string literal but also including double-quotes in the string literal body… As the (J)UEL specification says:

In section 1.3, "Literals", the specification states that "Quotes only need to be escaped in a string value enclosed in the same type of quote". This suggests that, e.g., "You could escape a single quote in a double-quoted string, but it's not necessary". JUEL guesses that you can't and that the above should read as "Quotes can only be escaped in a string value enclosed in the same type of quote".

Try something like this instead:


${userService.findUsers("{'id':'12'}")

or

${userService.findUsers('{"id":"12"}')

or even

${userService.findUsers("{\"id\":\"12\"}")
