Spring security 3中登录后跳转到不同页面

在spring security 3中，在登录 后，如何根据不同的需要跳转到不同的页面呢 ？ 
其中要 自定义的过滤器是 AuthenticationSuccessHandler， 

Java代码  


<?xml version="1.0" encoding="UTF-8"?>  

<beans:beans  

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

    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"  

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

    xsi:schemaLocation="  

        http://www.springframework.org/schema/security   

        http://www.springframework.org/schema/security/spring-security-3.1.xsd  

        http://www.springframework.org/schema/beans   

        http://www.springframework.org/schema/beans/spring-beans-3.2.xsd">  

   

    <http use-expressions="true" >  

        <intercept-url pattern="/login*" access="permitAll" />  

        <intercept-url pattern="/**" access="isAuthenticated()" />  

   

        <form-login login-page='/login.html'  

            authentication-failure-url="/login.html?error=true"  

            authentication-success-handler-ref="myAuthenticationSuccessHandler"/>  

   

        <logout/>  

    </http>  

   

    <beans:bean id="myAuthenticationSuccessHandler"  

        class="org.company.MySimpleUrlAuthenticationSuccessHandler" />  

   

    <authentication-manager>  

        <authentication-provider>  

            <user-service>  

                <user name="user1" password="user1Pass" authorities="ROLE_USER" />  

                <user name="admin1" password="admin1Pass" authorities="ROLE_ADMIN" />  

            </user-service>  

        </authentication-provider>  

    </authentication-manager>  

   

</beans:beans>  

  然后自定义的类要实现 AuthenticationSuccessHandler接口 ，代码如下 ： 
  

Java代码  


public class MySimpleUrlAuthenticationSuccessHandler implements AuthenticationSuccessHandler {  

    protected Log logger = LogFactory.getLog(this.getClass());  

   

    private RedirectStrategy redirectStrategy = new DefaultRedirectStrategy();  

   

    @Override  

    public void onAuthenticationSuccess(HttpServletRequest request,   

      HttpServletResponse response, Authentication authentication) throws IOException {  

        handle(request, response, authentication);  

        clearAuthenticationAttributes(request);  

    }  

   

    protected void handle(HttpServletRequest request,   

      HttpServletResponse response, Authentication authentication) throws IOException {  

        String targetUrl = determineTargetUrl(authentication);  

   

        if (response.isCommitted()) {  

            logger.debug("Response has already been committed. Unable to redirect to " + targetUrl);  

            return;  

        }  

   

        redirectStrategy.sendRedirect(request, response, targetUrl);  

    }  

   

     

    protected String determineTargetUrl(Authentication authentication) {  

        boolean isUser = false;  

        boolean isAdmin = false;  

        Collection<? extends GrantedAuthority> authorities = authentication.getAuthorities();  

        for (GrantedAuthority grantedAuthority : authorities) {  

            if (grantedAuthority.getAuthority().equals("ROLE_USER")) {  

                isUser = true;  

                break;  

            } else if (grantedAuthority.getAuthority().equals("ROLE_ADMIN")) {  

                isAdmin = true;  

                break;  

            }  

        }  

   

        if (isUser) {  

            return "/homepage.html";  

        } else if (isAdmin) {  

            return "/console.html";  

        } else {  

            throw new IllegalStateException();  

        }  

    }  

   

    protected void clearAuthenticationAttributes(HttpServletRequest request) {  

        HttpSession session = request.getSession(false);  

        if (session == null) {  

            return;  

        }  

        session.removeAttribute(WebAttributes.AUTHENTICATION_EXCEPTION);  

    }  

   

    public void setRedirectStrategy(RedirectStrategy redirectStrategy) {  

        this.redirectStrategy = redirectStrategy;  

    }  

    protected RedirectStrategy getRedirectStrategy() {  

        return redirectStrategy;  

    }  

}  

  其中要关注的是determineTargetUrl方法，传入 的参数是 Authentication类型的，然后进行权限的 判断
