为什么我没有收到Spring Security Login错误消息？

Question

使用Spring Security 3以及Struts 2和Tiles 2,我有一个登录页面,当它应该出现并按预期执行登录时 - 但是当我输入错误的用户凭据时,我返回到登录页面而没有关于什么地方出了错.我已经检查了所有配置参数,但我看不出问题出在哪里.

我的Spring Security XML配置如下:

 <http auto-config="true" use-expressions="true">
    <intercept-url pattern="/" access="permitAll" />
    <intercept-url pattern="/css/**" access="permitAll" />
    <intercept-url pattern="/images/**" access="permitAll" />
    <intercept-url pattern="/js/**" access="permitAll" />
    <intercept-url pattern="/public/**" access="permitAll" />
    <intercept-url pattern="/home/**" access="permitAll" />
    <intercept-url pattern="/user/**" access="hasRole('AUTH_MANAGE_USERS')" />
    <intercept-url pattern="/group/**" access="hasRole('AUTH_MANAGE_USERS')" />
    <intercept-url pattern="/**" access="isAuthenticated()" />
    <access-denied-handler error-page="/403.html"/>
    <form-login  login-page="/public/login.do" always-use-default-target="false"/>
    <logout invalidate-session="true" logout-success-url="/public/home.do"/>
</http>

我的Struts Action看起来像这样:

<package name="public" namespace="/public" extends="secure">
    <action name="login">
        <result name="success" type="tiles">tiles.login.panel</result>
        <result name="input" type="tiles">tiles.login.panel</result>
        <result name="error">/WEB-INF/jsp/error.jsp</result>
    </action>
    <action name="logout">
        <result name="success" type="redirect">/j_spring_security_logout</result>
    </action>
</package>

login.jsp页面(tile的一部分)从Spring Security中查找异常...

<c:if test="${not empty param.login_error}">
   <span class="actionError">
   Your login attempt was not successful, try again.<br/><br/>
        Reason: <c:out value="${SPRING_SECURITY_LAST_EXCEPTION.message}"/>.
  </span>
</c:if>
<form id="loginForm" name="loginForm" action="/j_spring_security_check" method="post">
  ...
</form>

谁能告诉我我失踪了什么？提前感谢任何/所有回复.

Spring Security未param.login_error自动设置.您需要按照以下方式进行操作:

<form-login  
    login-page="/public/login.do" 
    authentication-failure-url = "/public/login.do?login_error=1"
    always-use-default-target="false"/>
