Spring MVC，表单动作中的子文件夹 [英] Spring MVC, subfolder in form action

问题描述

我有问题，如何在动作属性中创建uri。

I have problem, how to create uri in action attribute. I have to use subfolders as "user", "admin" because I use Spring Security.

<form:form action="/user/reservationTour.html" method="post" commandName="bookTourForm">

结果，没有项目名称 http：// localhost：8080 / user / reservationTour.html

<form:form action="user/reservationTour.html" method="post" commandName="bookTourForm">

结果，2x链接中的用户 http：// localhost：8080 / ProjectContextTitle / user / user / reservationTour.html

Result, 2x user in link http://localhost:8080/ProjectContextTitle/user/user/reservationTour.html

<form:form action="<c:url value="/user/reservationTour.html" />" method="post" commandName="bookTourForm">

结果，例外

Result, exception

org.apache.jasper.JasperException: /jsp/user/reservationTourPage.jsp(7,33) Unterminated <form:form tag

这工作正常，但肯定不是很好的解决方案

This works fine, but sure not good solution

<form:form action="/ProjectContextName/user/reservationTour.html" method="post" commandName="bookTourForm">

推荐答案

如果您已经在用户目录中，只需要使用相对URL即可：

If you're already in the user directory, you just need to use a relative URL:

<form:form action="reservationTour.html" method="post" commandName="bookTourForm">

如果您想使用绝对网址，请使用< c：url> ; ，但不包含在另一个JSP标签的属性中：这是非法的。

If you want to use an absolute URL, use <c:url>, but don't include it in the attribute of another JSP tag: that's illegal.

<c:url value="/user/reservationTour.html" var="theAction"/>
<form:form action="${theAction}" ...>
