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 ? (String) map.get("type") : null; if (type == null) { principal = getSubject().getPrincipal(); } else { principal = getPrincipalFromClassName(type); } String property = map != null ? (String) map.get("property") : null; // Get the string value of the principal if (principal != null) { if (property == null) { strValue = principal.toString(); } else { strValue = getPrincipalProperty(principal, property); } } } if (strValue != null) { return strValue; } else { return null; } } /** * The hasRole tag * * @param roleName * @return */ public boolean hasRole(String roleName) { return getSubject() != null && getSubject().hasRole(roleName); } /** * The lacksRole tag * * @param roleName * @return */ public boolean lacksRole(String roleName) { boolean hasRole = getSubject() != null && getSubject().hasRole(roleName); return !hasRole; } /** * The hasAnyRole tag * * @param roleNames * @return */ public boolean hasAnyRole(String roleNames) { boolean hasAnyRole = false; Subject subject = getSubject(); if (subject != null) { // Iterate through roles and check to see if the user has one of the // roles for (String role : roleNames.split(",")) { if (subject.hasRole(role.trim())) { hasAnyRole = true; break; } } } return hasAnyRole; } /** * The hasPermission tag * * @param p * @return */ public boolean hasPermission(String p) { return getSubject() != null && getSubject().isPermitted(p); } /** * The lacksPermission tag * * @param p * @return */ public boolean lacksPermission(String p) { return !hasPermission(p); } @SuppressWarnings({ "unchecked" }) private Object getPrincipalFromClassName(String type) { Object principal = null; try { Class cls = Class.forName(type); principal = getSubject().getPrincipals().oneByType(cls); } catch (ClassNotFoundException e) { } return principal; } private String getPrincipalProperty(Object principal, String property) { String strValue = null; try { BeanInfo bi = Introspector.getBeanInfo(principal.getClass()); // Loop through the properties to get the string value of the // specified property boolean foundProperty = false; for (PropertyDescriptor pd : bi.getPropertyDescriptors()) { if (pd.getName().equals(property)) { Object value = pd.getReadMethod().invoke(principal, (Object[]) null); strValue = String.valueOf(value); foundProperty = true; break; } } if (!foundProperty) { final String message = "Property [" + property + "] not found in principal of type [" + principal.getClass().getName() + "]"; throw new RuntimeException(message); } } catch (Exception e) { final String message = "Error reading property [" + property + "] from principal of type [" + principal.getClass().getName() + "]"; throw new RuntimeException(message, e); } return strValue; } protected Subject getSubject() { return SecurityUtils.getSubject(); } public static void main(String[] args) { GroupTemplate gt = new GroupTemplate(); gt.registerFunctionPackage("shiro", new ShiroExt()); } }
