我已经使用 Spring MVC、Restful webservices 为移动客户端实现了服务器后端。我想用弹簧安全保护应用程序。我已经放置了一个自定义 login.jsp 来处理登录,如下所示。
<body onload='document.f.j_username.focus();'>
<h3>Login with Username and Password (Custom Page)</h3>
<c:if test="${not empty error}">
<div class="errorblock">
Your login attempt was not successful, try again.<br /> Caused :
${sessionScope["SPRING_SECURITY_LAST_EXCEPTION"].message}
</div>
</c:if>
<form name='f' action="<c:url value='j_spring_security_check' />"
method='POST'>
<table>
<tr>
<td>User:</td>
<td><input type='text' name='j_username' value=''>
</td>
</tr>
<tr>
<td>Password:</td>
<td><input type='password' name='j_password' />
</td>
</tr>
<tr>
<td colspan='2'><input name="submit" type="submit"
value="submit" />
</td>
</tr>
<tr>
<td colspan='2'><input name="reset" type="reset" />
</td>
</tr>
</table>
</form>
我的 web.xml 如下。
<display-name>Spring MVC Application</display-name>
<!-- Spring MVC -->

spring-security-context.xml 如下所示。

但我收到关于日食的警告
在 Java 构建路径上找不到“c:if”的标记处理程序类 (org.apache.taglibs.standard.tag.rt.core.IfTag)
当我提交表单时,在 j_spring_security_check 上得到一个 not found 错误。我在类路径中包含了 jstl1.2。为什么即使我包含了标记库,我也会收到未找到标记处理程序的警告?
