我开发了一个 Spring 应用程序，并在其中实现了 Spring 安全集成到登录和注销功能。我使用 Spring security 和 xml 配置。但是当我登录系统时，它显示404。控制台告诉我，在名称为“appServlet”的 DispatcherServlet 中未找到带有 URI [/pms/j_spring_security_check] 的 HTTP 请求的映射
但我无法理解这个错误。我错过了什么？

我的控制器方法：
@RequestMapping(value="/login", method = RequestMethod.GET)
public ModelAndView printWelcome() {
ModelAndView modelAndView = new ModelAndView();
modelAndView.addObject("message", "Spring security allows you");
modelAndView.setViewName("loginForm");
return modelAndView;
}
My spring-security.xml :
<beans:beans xmlns="http://www.springframework.org/schema/security"
xmlns:beans="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

<http auto-config="true">

<user-service>
<user name="a2ztechguide" password="123456" authorities="ROLE_USER" />

</beans:beans>
And 我的登录页面：
<body>
<table>
<tr>
<td valign="top"><c:if test="${not empty param.login_error}">
<font color="red"> Invalid user name or password, try again.
<br /> <br />
</font>
</c:if>
<form name="login_form"
action="<c:url value='j_spring_security_check'/>" method="POST">
<div>
<table width="40%" border="0" cellpadding="0" cellspacing="0">

<td valign="top">
<table border="0" cellspacing="0" cellpadding="4" width="40%">
<tr>
<td colspan="2">Custom Login Form

<td></td>
</tr>
<tr>
<td width="80">Username</td>
<td valign="top" align="left"><input type='text'
id='username' size="30" maxlength="40" name='j_username'
value='<c:if test="${not empty param.login_error}">
<c:out value="${SPRING_SECURITY_LAST_USERNAME}"/>
</c:if>' />
</td>
</tr>
<tr>
<td width="80">Password</td>
<td valign="top" align="left"><input type='password'
name='j_password' size="30" maxlength="30"></td>
</tr>
<tr>
<td></td>
<td><input type="submit" value="Submit" /></td>
</tr>
</table>
</td>
</tr>
</table>
</div>
</form></td>
</tr>
</table>
</body>
请帮我。
我最终通过修改声明自定义登录表单页面的行解决了这个问题。
添加了处理url =“/j_spring_security_check”：
<form-login login-page="/login" default-target-url="/admin" login-processing-url="/j_spring_security_check" authentication-failure-url="/login?error" username-parameter="username" password-parameter="password"/>
到我的 security-context.xml 页面
