请问在login.jsp
页面中,参数param.error
和param.logout
的变量来源在哪里?
我使用了Spring Boot框架的Spring Security。
<c:if test="${param.error != null}">
<div class="alert alert-danger">
Invalid username and password.
</div>
</c:if>
<c:if test="${param.logout != null}">
<div class="alert alert-success">
You have been logged out successfully.
</div>
</c:if>
