怎么利用shiro权限动态控制每个url资源呢?主要包括jsp(html)页面、action的url访问,而静态资源和登录资源则可直接访问。
所谓动态控制url就是url的权限控制不是手动写死在配置文件中,而是根据数据库的变化而变化。
表结构:
user2:用户表
t_role:角色表
t_user_role:用户角色表
t_privilege:权限资源表
t_role_privilege:角色权限资源表
shiro动态控制url资源:
applicationContext-shiro.xml配置chainDefinitionSectionMetaSource:

ChainDefinitionSectionMetaSource.java:
package com.test.www.web.filter; import java.text.MessageFormat; import java.util.List; import javax.annotation.Resource; import org.apache.commons.lang3.StringUtils; import org.apache.shiro.config.Ini; import org.apache.shiro.config.Ini.Section; import org.springframework.beans.factory.FactoryBean; import com.test.www.web.entity.user.TPrivilege; import com.test.www.web.service.user.TPrivilegeService; public class ChainDefinitionSectionMetaSource implements FactoryBean<Ini.Section>{ public static final String PREMISSION_STRING="perms[\"{0}\"]"; private String filterChainDefinitions; /*private PrivilegeDao privilegeDao; public PrivilegeDao getPrivilegeDao() { return privilegeDao; }*/ @Resource private TPrivilegeService tPrivilegeService; public String getFilterChainDefinitions() { return filterChainDefinitions; } @Resource public void setFilterChainDefinitions(String filterChainDefinitions) { String fiter="";//改正后的url配置 /*List<Privilege> list = privilegeDao.getAll(); for (Iterator<Privilege> it = list.iterator(); it.hasNext();) { Privilege privilege = it.next(); if(!StringUtils.isEmpty(privilege.getUrl())) { fiter+="/"+privilege.getUrl()+" = authc," +MessageFormat.format(PREMISSION_STRING,privilege.getPerms()) +"\n"; }//追加beans.xml中已经有的过滤 }*/ List<TPrivilege> tPrivilegeList = tPrivilegeService.selectAllPrivileges(); if(tPrivilegeList!=null && tPrivilegeList.size()>0){ for (TPrivilege tPrivilege : tPrivilegeList) { if(!StringUtils.isEmpty(tPrivilege.getUrl())) { fiter += tPrivilege.getUrl()+" = authc," +MessageFormat.format(PREMISSION_STRING,tPrivilege.getUrl()) +"\n"; }//追加beans.xml中已经有的过滤 } } //对url拦截 fiter += "/**"+" = authc" +"\n"; //fiter+="/test/add.html"+" = authc," +MessageFormat.format(PREMISSION_STRING,"/test/add.html") +"\n"; //fiter+="/js/**"+" = authc," +MessageFormat.format(PREMISSION_STRING,"/js/**") +"\n"; //fiter+="/js/**"+" = " +MessageFormat.format(PREMISSION_STRING,"/js/**") +"\n"; System.out.println(filterChainDefinitions+fiter); this.filterChainDefinitions = filterChainDefinitions+fiter; } /*@Resource public void setPrivilegeDao(PrivilegeDao privilegeDao) { this.privilegeDao = privilegeDao; }*/ public Section getObject(){ Ini ini = new Ini();//网上好多都是在这里配置URL的。但是发现是错误的。 ini.load(filterChainDefinitions); Ini.Section section = ini.getSection(Ini.DEFAULT_SECTION_NAME); return section; } public Class<?> getObjectType() { return this.getClass(); } public boolean isSingleton() { return false; } }
服务器启动的时候会执行ChainDefinitionSectionMetaSource类,加载系统权限资源表所有的url到filterChainDefinitions中(在filterChainDefinitions后追加),从而实现对所有url资源的权限控制的配置:
这个类就是用来在filterChainDefinitions中追加url资源权限控制的。
注意:
/** = authc应放在最后,否则会影响追加的权限资源的控制。
当访问资源的时候,例如/test/toAddUser.html,就会进入shiro授权方法中进行权限校验,如果没有权限则进入到401未授权,否则正常访问。

至此,shiro动态控制url权限资源已完成。
说明:
url资源(action、静态html或动态页面jsp的url)保存在数据库中。
