Getting current date in JSTL EL and doing arithmetic on it

问题 Without using scriptlets, what's the correct way for doing date arithmetic in JSP? Here are examples what I'm trying to do: Get current year (YYYY) Subtract current year by one to get previous year (YYYY) Thanks! 回答1: Use <jsp:useBean> to construct new Date. Use JSTL <fmt:formatDate> to get the year out of it. Use EL to substract it. <%@taglib prefix="fmt" uri="http://java.sun.com/jsp/jstl/fmt" %> <jsp:useBean id="now" class="java.util.Date" /> <fmt:formatDate var="year" value="${now}"

问题 I have an integer which I want to convert to class Date . I assume I first need to convert it to a string, but how? My attempt: v <- 20081101 date <- as.Date(v, format("%Y%m%d")) Error in charToDate(x) : character string is not in a standard unambiguous format Using paste() works, but is that really the correct way to do the conversion? date <- as.Date(paste(v), format("%Y%m%d")) date [1] "2008-11-01" class(date) # [1] "Date" 回答1: as.character() would be the general way rather than use paste(
