Answer 1

您应该提供控制器，index.jsp和默认登录页面。以便一个人可以分析并帮助您解决问题。希望您尽快上传详细信息。

Answer 2

Looking into your code i found one mistake not related to your problem but still its need to be corrected for using the spring security for login you should use in login form

<form  name="login" action="<c:url value='j_spring_security_check'/>" method="POST" >

<input type="text" class="form-control" id="username" placeholder="Enter Username" name='j_username'>
<input type="password" class="form-control" id="password" placeholder="Password" name='j_password'>

</form>
