如何在 grails 和 spring-security-core 中设置 gsp 片段？

Question

我有一个 gsp 块，我想重用并制作一个小 gsp 片段：

<sec:ifLoggedIn>
    <g:link controller="user" action="showProfile">My Profile</g:link> |
    <g:link controller="privateMessage" action="list">Inbox</g:link> |
    <g:link controller="user" action="showPreferences">Preferences</g:link> |
    <g:link controller="logout" action="index">Logout</g:link>
</sec:ifLoggedIn>
<sec:ifNotLoggedIn>
    <form id="loginForm" action="/myproject/j_spring_security_check" method="POST">
        <fieldset>
            <input type='text' name='j_username' id='username' size="15" />
            <input type='password' name='j_password' id='password' size="15" />
            <input type="submit" value="Login" class="button" />
            <a href="#">Register</a>
        </fieldset>
    </form>
</sec:ifNotLoggedIn>

我了解到可以使用 g:render template="_loginStuff" 将模板与其余标记合并。然而，使用 Spring Security 这样做会导致错误：

我不知道我是否使用不正确，或者我的模板是否需要位于特殊文件夹中...或者 Spring-security-core 是否不允许根本用过。帮助？
