Format number with JSTL and no rounding

由 半城伤御伤魂 提交于 2020-01-24 01:28:16
问题 I need to format number using <fmt:formatNumber/> jstl tag. The output should be restricted to 3 places after the decimal point, but rounding isn't allowed, so using the attribute maxFractionDigits="3" isn't appropriate, cause it rounds the number. Do you have any suggestions? 回答1: You could subtract 0.0005 from the number before formatting it. That way the rounding will be equivalent to truncating the original number to 3 decimal places. <fmt:formatNumber value="${myNumber - 0.0005}"

How can you store JSP buffered output from an include/import to a variable?

由 放肆的年华 提交于 2020-01-16 08:30:09
问题 I don't want to use any Java code, I just want to use <jsp:include> or <c:import> or something to that effect. So that I can use <c:set var="myPage" value="bufferedPageOutput" /> to output the generated HTML later. How can I do this with JSP/JSTL/Struts? 回答1: The <c:import> tag can take an optional var attribute, which stores the imported content as a variable. <c:import var="myPage" url="uri/to/import"/> Very useful 来源： https://stackoverflow.com/questions/2563735/how-can-you-store-jsp
