Package jp.co.actoweb.core.interceptor;
Import Javax.servlet.http.HttpServletRequest;
Import Javax.servlet.http.HttpServletResponse;

Import javax.servlet.http.HttpSession;
Import Org.springframework.web.servlet.HandlerInterceptor;

Import Org.springframework.web.servlet.ModelAndView;

Import jp.co.actoweb.core.Constants;

	public class Logininterceptor implements Handlerinterceptor {private String homeurlmapping; @Override public boolean prehandle (HttpServletRequest request, httpservletresponse response, Object handler) throws Ex
		ception {HttpSession session = Request.getsession (); if (session!= null && session.getattribute (constants.session_key_auth_info)!= null) {Response.sendredirect (R
			Equest.getcontextpath () + gethomeurlmapping ());
		return false;
	return true; @Override public void Aftercompletion (HttpServletRequest request, httpservletresponse response, Object handler, EXCEP tion ex) throws Exception {} @Override public void Posthandle (HttpServletRequest request, HttpServletResponse response, Object handler, Modelandview Modelandview) throws Exception {
	Public String gethomeurlmapping () {return homeurlmapping;
	} public void Sethomeurlmapping (String homeurlmapping) {this.homeurlmapping = homeurlmapping;
 }

}

Configuration of the Interceptor in Mvc-config.xml

<bean id= "Logininterceptor" class= "Jp.co.actoweb.core.interceptor.LoginInterceptor" >
		<property name= "Homeurlmapping" value= "/admin/home/init.do"/>
	</bean>

<mvc:interceptor>
	    	<mvc:mapping path= "/**/admin/welcome.do"/>
