shrio 提供有jsp 标签，供在jsp 里使用，如果想在beetl中使用，有俩种方法，

一是beetl支持集成jsp页面，所以你可以在在jsp里使用shrio标签

另外，beetl 使用自定义函数写了shiro tag功能，你可以像使用shiro标签那样使用shiro

package com.ext;import java.beans.BeanInfo;import java.beans.Introspector;import java.beans.PropertyDescriptor;import java.util.Map;import org.apache.shiro.SecurityUtils;import org.apache.shiro.subject.Subject;import org.bee.tl.core.GroupTemplate;/*gt.registerFunctionPackage("so",new ShiroExt ());你可以在模板里直接调用，譬如@if(so.isGuest()) {*/public class ShiroExt {	/**	 * The guest tag	 * 	 * @return	 */	public boolean isGuest() {		return getSubject() == null || getSubject().getPrincipal() == null;	}	/**	 * The user tag	 * 	 * @return	 */	public boolean isUser() {		return getSubject() != null && getSubject().getPrincipal() != null;	}	/**	 * The authenticated tag	 * 	 * @return	 */	public boolean isAuthenticated() {		return getSubject() != null && getSubject().isAuthenticated();	}	public boolean isNotAuthenticated() {		return !isAuthenticated();	}	/**	 * The principal tag	 * 	 * @param map	 * @return	 */	public String principal(Map map) {		String strValue = null;		if (getSubject() != null) {			// Get the principal to print out			Object principal;			String type = map != null ?
