spring security custome登录页面未显示

Question

我在jsf中使用spring security。

我想要Home.xhtml，login.xhtml显示。

这是我的applicationContext.xml

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xmlns:security="http://www.springframework.org/schema/security"
       xsi:schemaLocation="http://www.springframework.org/schema/beans
       http://www.springframework.org/schema/beans/spring-beans.xsd
              http://www.springframework.org/schema/security
       http://www.springframework.org/schema/security/spring-security.xsd">

    <security:http auto-config="true">
        <security:form-login login-page="/login.xhtml" default-target-url="/"/>
        <security:intercept-url pattern="/login.xhtml" access="IS_AUTHENTICATED_ANONYMOUSLY"/>
        <security:intercept-url pattern="/Home.xhtml" access="hasRole('ROLE_USER')"/>
    </security:http>

    <security:authentication-manager>
        <security:authentication-provider>
            <security:user-service>
                <security:user name="sajjad" password="200200" authorities="ROLE_USER"/>
            </security:user-service>
        </security:authentication-provider>
    </security:authentication-manager>
</beans>

这是web.xml：

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns="http://xmlns.jcp.org/xml/ns/javaee"
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-app_3_1.xsd"
         version="3.1">

    <context-param>
        <param-name>contextConfigLocation</param-name>
        <param-value>/WEB-INF/applicationContext.xml</param-value>
    </context-param>

    <filter>
        <filter-name>springSecurityFilterChain</filter-name>
        <filter-class>org.springframework.web.filter.DelegatingFilterProxy</filter-class>
    </filter>

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

    <listener>
        <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
    </listener>

    <servlet>
        <servlet-name>Faces Servlet</servlet-name>
        <servlet-class>javax.faces.webapp.FacesServlet</servlet-class>
        <load-on-startup>1</load-on-startup>
    </servlet>

    <servlet-mapping>
        <servlet-name>Faces Servlet</servlet-name>
        <url-pattern>*.xhtml</url-pattern>
    </servlet-mapping>
</web-app>

LoginBean.java：

@ManagedBean
@SessionScoped
public class LoginBean {

    private String name;
    private String pwd;

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public String getPwd() {
        return pwd;
    }

    public void setPwd(String pwd) {
        this.pwd = pwd;
    }

    public String login() throws IOException {
        FacesContext.getCurrentInstance().getExternalContext().dispatch("j_spring_security_check");
        FacesContext.getCurrentInstance().responseComplete();
        return null;
    }
}

但是当我请求http://localhost:8080/Home.xhtml时，显示的Home.xhtml没有使用定义的login.xhtml页面进行身份验证。
