CAS验证成功后不能跳转到登陆成功的主页面

现在部署了CAS,有一个应用,下载输入应用的URL可以正确跳转到CAS服务的登陆界面,登陆验证通过后页面却跳转到了应用的登陆界面，不能直接进入登陆成功的主页面！
应用的web.xml如下

<!-- 用于单点登录 -->
	<filter>
		<filter-name>CASFilter</filter-name>
		<filter-class>org.jasig.cas.client.authentication.AuthenticationFilter</filter-class>
		<init-param>
			<param-name>casServerLoginUrl</param-name>
			<param-value>https://TP_1010000110011000:8443/cas/login</param-value>
		</init-param>
		<init-param>
			<param-name>serverName</param-name>
			<param-value>http://localhost:8080</param-value>
		</init-param>
	</filter>
	<filter-mapping>
		<filter-name>CASFilter</filter-name>
		<url-pattern>/*</url-pattern>
	</filter-mapping>

	<!-- 该过滤器负责Ticket的校验工作 -->
	<filter>
		<filter-name>CAS Validation Filter</filter-name>
		<filter-class>
			org.jasig.cas.client.validation.Cas20ProxyReceivingTicketValidationFilter</filter-class>
		<init-param>
			<param-name>casServerUrlPrefix</param-name>
			<param-value>https://TP_1010000110011000:8443/cas</param-value>
		</init-param>
		<init-param>
			<param-name>serverName</param-name>
			<param-value>http://localhost:8080</param-value>
		</init-param>
	</filter>
	<filter-mapping>
		<filter-name>CAS Validation Filter</filter-name>
		<url-pattern>/*</url-pattern>
	</filter-mapping>

	<!-- 该过滤器负责实现HttpServletRequest请求的包裹 -->
	  	<filter>
			<filter-name>CAS HttpServletRequest Wrapper Filter</filter-name>
			<filter-class>
				org.jasig.cas.client.util.HttpServletRequestWrapperFilter</filter-class>
		</filter>
		<filter-mapping>
			<filter-name>CAS HttpServletRequest Wrapper Filter</filter-name>
			<url-pattern>/*</url-pattern>
		</filter-mapping>

	<!--自定义cas设置user过滤器-->
		  <filter>
		<display-name>AutoSetUserAdapterFilter</display-name>
		<filter-name>AutoSetUserAdapterFilter</filter-name>
		<filter-class>com.cdt.cas.client.casClientFilter</filter-class>
	</filter>
	<filter-mapping>
		<filter-name>AutoSetUserAdapterFilter</filter-name>
		<url-pattern>/*</url-pattern>
	</filter-mapping>

casClientFilter的代码如下:

public void doFilter(ServletRequest servletRequest, ServletResponse servletResponse,
			FilterChain chain) throws IOException, ServletException {
		Date startTime = new Date();
		System.out.println("CasClient开始时间"+startTime.getTime());
		final HttpServletRequest request = (HttpServletRequest) servletRequest;
		final HttpServletResponse response = (HttpServletResponse) servletResponse;
		final HttpSession session = request.getSession(false);
		final Assertion assertion = (Assertion) (session == null ? request
				.getAttribute(AbstractCasFilter.CONST_CAS_ASSERTION) : session
				.getAttribute(AbstractCasFilter.CONST_CAS_ASSERTION));
		String username = assertion == null ? null : assertion.getPrincipal().getName();
		//_const_cas_assertion_是CAS中存放登录用户名的session标志
	    Object object = request.getSession().getAttribute("_const_cas_assertion_");
	  
	    
	    String url = request.getRequestURL().toString();
		if(object != null && username != null) {

			//存放用户类型
			session.setAttribute("userType", "2");
			//设置cookie
			Cookie cookie = new Cookie("username",username);
			int maxAge = 60*60*24*365;	//cookie存活时间1年
			cookie.setMaxAge(maxAge);
			response.addCookie(cookie);



		}
		if (chain != null) {
			chain.doFilter(request, response);
		}
		Date endTime = new Date();
		System.out.println("CasClient结束时间"+endTime.getTime());
	}

讨教各位高手！这个到底怎么弄啊！现在一直跳转到登陆页面！没有进入到登陆成功的页面啊！
