spring - j_spring_security_check 不可用。请帮助Spring3登录

Question

我正在尝试在 Spring3 中写一些具有安全性的东西。我试图使用默认的登录屏幕，每个人都说 Spring 会为您显示该屏幕。但经过两天的尝试并收到错误:

/spring-security-login not found

我放弃并将代码更改为:

<http  auto-config="true"> 
<intercept-url pattern="/friends/**" access="ROLE_USER,ROLE_ADMIN"  />
<form-login login-page="/login.jsp" 
        default-target-url="/friends/add.html"
        authentication-failure-url="/login.jsp?authfailed=true" />
</http>

我将login.jsp添加到我的项目中，我认为我做得对。现在我收到此错误:

HTTP Status 404 - /MySpring/j_spring_security_check message /MySpring/j_spring_security_check description The requested resource (/MySpring/j_spring_security_check) is not available.

将其添加到您的 web.xml

<filter-mapping>
    <filter-name>springSecurityFilterChain</filter-name>
    <url-pattern>/*</url-pattern>
    <dispatcher>REQUEST</dispatcher>
    <dispatcher>FORWARD</dispatcher>
</filter-mapping>
