JSTL - c:url不使用表单操作

Question

我在使用标记在JSP中设置表单的路径时遇到了问题.我也在表格标签之外,它工作正常.但是它似乎在spring form标签内部不起作用.我做错了什么或者它在其他JSTL标签内不起作用？提前致谢!

这是表单标签外的版本打印正确的版本.

/ searchtool /用户/添加

这是表单操作设置为:

/ searchtool /用户/%3CC:URL%20value = '/用户/添加' %20 /%3E

<%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c" %>
<%@ taglib prefix="sf" uri="http://www.springframework.org/tags/form" %>
<%@ taglib prefix="spring" uri="http://www.springframework.org/tags" %>

<div class="container">
    <div class="row">
        <div class="col-xs-12 col-sm-8 col-md-6">
            <h3>User - Add</h3>
            <br>

            <spring:hasBindErrors name="user.*">
                <div class="alert alert-danger">
                    <sf:errors path="firstName"></sf:errors>
                    <sf:errors path="lastName"></sf:errors>

                    <sf:errors path="password"></sf:errors>
                </div>
            </spring:hasBindErrors>

            <sf:form commandName="user" method="post" action="<c:url value='/user/add' />"> <c:url value='/user/add' />
                <div class="form-group">

您不能在标记内使用标记.所以只需按如下方式分隔您的标签:

<c:url var="post_url"  value="/user/add" />
<sf:form commandName="user" method="post" action="${post_url}">
