由 本秂侑毒 提交于 2019-12-22 03:38:07
问题 This question already has answers here : Convert and format a Date in JSP (6 answers) Closed 3 years ago . I want to take date from DB and display on jsp: 2014-04-02 instead of: 2014-04-02 00:00:00.0 On jsp I tried to use c:fmt tag for formatting date: <div class="form-group"> <span><fmt:message key="task.start"/></span> <input class="form-control" id="firstDate" placeholder="<fmt:message key="task.start"/>" name="start_date-${task.taskId}" <fmt:formatDate value="${task.startDate}" var=

How to debug JSTL?

由 天涯浪子 提交于 2019-12-22 01:39:29
问题 I'm using SpringSource Tool Suite (with Roo) and have some success. What bothers me though is that I don't know how to debug tag library-stuff. I may add breakpoints but it never stops at them. What I'm looking for is a dump of all current variables in the context. Up until now I did something like: <c:forEach items="${data}" var="item"> <c:out value="${item}"></c:out><br /> </c:forEach> Sadly, that's difficult to read and also not pretty straightforward. What can I do to improve this? 回答1:

maven中pom.xml引入jar包小结

由 拟墨画扇 提交于 2019-12-22 00:43:53
用maven中的pom.xml引入包非常方便，在这我就记录一下我经常用的几个设置，配完pom.xml后只需reimport即可（不断更新中）： junit： 用于测试 <dependency> <groupId>junit</groupId> <artifactId>junit</artifactId> <version>4.10</version> <scope>test</scope> </dependency> guava：google用于优化java原生类的扩展包 <dependency> <groupId>com.google.guava</groupId> <artifactId>guava</artifactId> <version>18.0</version> </dependency> log4j： 日志相关扩展包，用system.out.print和printstacktrace在实际中是不被允许的 <dependency> <groupId>log4j</groupId> <artifactId>log4j</artifactId> <version>1.2.9</version> </dependency> servlet：不多说，web相关 <dependency> <groupId>javax.servlet</groupId> <artifactId

calling another variable using a variable value as parameter in jstl

由 耗尽温柔 提交于 2019-12-21 23:10:34
问题 the logic is somehow like this: <c:set var="vehicle" value="car"> <c:set var="car" value="ferrari"> since the value of ${vehicle} = "car" which is also the name of the variable with the value of "ferrari" i access it indirectly using ${'${vehicle}'} but it doesn't seem to work. Can someone help me with this. thanks 回答1: This kind of things doesn't usually work in java (there's no eval statement). In this case however, the variables are bound to the request context, so I guess you could access

What's the difference between the various JSTL libraries out there and which to use?

由 南楼画角 提交于 2019-12-21 17:18:43
问题 I'm puzzled because of build and run errors that mislead me. From them, I can't quite figure out what the distinction is between the various JavaServer Page Standard Tag Libraries. For instance, I see: jstl.jar (in Apache Tomcat) jstl-1.2.jar (in Tomahawk examples) jstl-impl.jar (in GlassFish) In times past, I've used (and recently recovered and have stored privately against disaster) from javax.servlet.jsp.jstl jstl-api-1.2.jar jstl-impl-1.2.jar These latter are the only ones I seem to be

Using java.time.LocalDate with JSTL <fmt:formatDate> action

由 折月煮酒 提交于 2019-12-21 13:03:26
问题 I haven't been able to figure out how to display a java.time.LocalDate value in a JSP. In my JSP, I have this: <fmt:formatDate value="${std.datum}" type="date" pattern="dd.MM.yyyy" var="stdDatum" /> The std.datum is of type java.time.LocalDate. When rendering the JSP I get this exception: javax.el.ELException: Cannot convert 2015-02-14 of type class java.time.LocalDate to class java.util.Date I'm assuming it's the conversion? So is it possible to format an instance of LocalDate class with
