Java UsernamePasswordAuthenticationFilter问题

我有一个SpringSecurity3应用程序，我登录和注销都很好。我想为我的应用程序实现我自己的用户名PasswordAuthenticationFilter。我遵循了那个教程：

我的过滤类是：

package security;

import org.springframework.security.core.Authentication;
import org.springframework.security.core.AuthenticationException;
import org.springframework.security.web.authentication.UsernamePasswordAuthenticationFilter;

import javax.servlet.ServletException;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import java.io.IOException;

public class CustomUsernamePasswordAuthenticationFilter extends UsernamePasswordAuthenticationFilter {
    @Override
    protected void successfulAuthentication(HttpServletRequest request, HttpServletResponse response, Authentication authResult) throws IOException, ServletException {
        super.successfulAuthentication(request, response, authResult);
        System.out.println("==successful login==");
    }

    @Override
    protected void unsuccessfulAuthentication(HttpServletRequest request, HttpServletResponse response, AuthenticationException failed) throws IOException, ServletException {
        super.unsuccessfulAuthentication(request, response, failed);
        System.out.println("==failed login==");
    }
}

我的安全xml配置文件：

<beans:beans xmlns="http://www.springframework.org/schema/security"
             xmlns:beans="http://www.springframework.org/schema/beans"

    </beans:bean>
    <beans:bean id="failureHandler"
                class="org.springframework.security.web.authentication.SimpleUrlAuthenticationFailureHandler">

                      authorities="ROLE_USER"/>
            </user-service>
        </authentication-provider>
    </authentication-manager>

</beans:beans>

我所有的网页。有什么想法吗？我的应用程序配置好了吗

PS:在教程中写道：

注意：由于我们正在替换默认的FORM\u LOGIN\u过滤器，因此我们应该 不用 所以我删除了：

    <form-login
            login-page="/login3.html"
            login-processing-url="/j_spring_security_check"
            default-target-url="/index.html"
            always-use-default-target="true"/>
    <logout logout-url="/j_spring_security_logout"
            logout-success-url="/login.html"/>

从我的XML文件

还需要定义successHandler和failureHandler，因为我没有覆盖它们。如果我这样做是因为我正在更换过滤器（或者因为-

http auto-config=“false”

我不知道这句话的真正目的，如果你解释你是受欢迎的）我应该定义任何其他的安全吗

我是Spring Security 3和Spring的新手。

我解决了以下问题：入口点ref=“loginUrlAuthenticationEntryPoint”不应位于不同的http标记处

    <form-login
            login-page="/login3.html"
            login-processing-url="/j_spring_security_check"
            default-target-url="/index.html"
            always-use-default-target="true"/>
    <logout logout-url="/j_spring_security_logout"
            logout-success-url="/login.html"/>
