shiro

apache shiro 是一个轻量级的身份验证与授权框架，与spring security 相比较，简单易用，灵活性高，springboot本身是提供了对security的支持，毕竟是自家的东西。springboot暂时没有集成shiro，这得自己配。

shiro 内置过滤器

本文实现：

本文实现从数据库读取用户信息，获取当前用户的权限或角色，通过配置文件过滤用户的角色或权限。拥有相应的角色或者相应的权限的用户可以访问相应的url。

数据库设计

springboot集成shiro 实现权限控制（转）_spring

1. 添加依赖

  <dependency><groupId>org.apache.shiro</groupId><artifactId>shiro-spring</artifactId><version>1.2.5</version></dependency><dependency><groupId>org.apache.shiro</groupId><artifactId>shiro-ehcache</artifactId><version>1.2.5</version></dependency><dependency><groupId>com.github.theborakompanioni</groupId><artifactId>thymeleaf-extras-shiro</artifactId><version>1.2.1</version></dependency>

2. 添加shiro 配置

package com.us.shiro;import org.apache.shiro.authc.credential.HashedCredentialsMatcher;import org.apache.shiro.spring.LifecycleBeanPostProcessor;import org.apache.shiro.spring.security.interceptor.AuthorizationAttributeSourceAdvisor;import org.apache.shiro.spring.web.ShiroFilterFactoryBean;import org.apache.shiro.web.filter.authc.LogoutFilter;import org.apache.shiro.web.mgt.DefaultWebSecurityManager;import org.springframework.aop.framework.autoproxy.DefaultAdvisorAutoProxyCreator;import org.springframework.boot.autoconfigure.condition.ConditionalOnMissingBean;import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;import org.springframework.context.annotation.DependsOn;
import javax.servlet.Filter;import java.util.LinkedHashMap;import java.util.Map;
/**
 * shiro配置类
 * Created by cdyoue on 2016/10/21.
 */@Configurationpublic class ShiroConfiguration {
/**
     * LifecycleBeanPostProcessor，这是个DestructionAwareBeanPostProcessor的子类，
     * 负责org.apache.shiro.util.Initializable类型bean的生命周期的，初始化和销毁。
     * 主要是AuthorizingRealm类的子类，以及EhCacheManager类。
     */@Bean(name = "lifecycleBeanPostProcessor")public LifecycleBeanPostProcessor lifecycleBeanPostProcessor() {return new LifecycleBeanPostProcessor();
    }
/**
     * HashedCredentialsMatcher，这个类是为了对密码进行编码的，
     * 防止密码在数据库里明码保存，当然在登陆认证的时候，
     * 这个类也负责对form里输入的密码进行编码。
     */@Bean(name = "hashedCredentialsMatcher")public HashedCredentialsMatcher hashedCredentialsMatcher() {
        HashedCredentialsMatcher credentialsMatcher = new HashedCredentialsMatcher();
        credentialsMatcher.setHashAlgorithmName("MD5");
        credentialsMatcher.setHashIterations(2);
        credentialsMatcher.setStoredCredentialsHexEncoded(true);return credentialsMatcher;
    }/**ShiroRealm，这是个自定义的认证类，继承自AuthorizingRealm，
     * 负责用户的认证和权限的处理，可以参考JdbcRealm的实现。
     */@Bean(name = "shiroRealm")@DependsOn("lifecycleBeanPostProcessor")public ShiroRealm shiroRealm() {
        ShiroRealm realm = new ShiroRealm();//        realm.setCredentialsMatcher(hashedCredentialsMatcher());return realm;
    }//    /**//     * EhCacheManager，缓存管理，用户登陆成功后，把用户信息和权限信息缓存起来，//     * 然后每次用户请求时，放入用户的session中，如果不设置这个bean，每个请求都会查询一次数据库。//     *///    @Bean(name = "ehCacheManager")//    @DependsOn("lifecycleBeanPostProcessor")//    public EhCacheManager ehCacheManager() {//        return new EhCacheManager();//    }
/**
     * SecurityManager，权限管理，这个类组合了登陆，登出，权限，session的处理，是个比较重要的类。
//     */@Bean(name = "securityManager")public DefaultWebSecurityManager securityManager() {
        DefaultWebSecurityManager securityManager = new DefaultWebSecurityManager();
        securityManager.setRealm(shiroRealm());//        securityManager.setCacheManager(ehCacheManager());return securityManager;
    }
/**
     * ShiroFilterFactoryBean，是个factorybean，为了生成ShiroFilter。
     * 它主要保持了三项数据，securityManager，filters，filterChainDefinitionManager。
     */@Bean(name = "shiroFilter")public ShiroFilterFactoryBean shiroFilterFactoryBean() {
        ShiroFilterFactoryBean shiroFilterFactoryBean = new ShiroFilterFactoryBean();
        shiroFilterFactoryBean.setSecurityManager(securityManager());


        Map<String, Filter> filters = new LinkedHashMap<>();
        LogoutFilter logoutFilter = new LogoutFilter();
        logoutFilter.setRedirectUrl("/login");//        filters.put("logout",null);
        shiroFilterFactoryBean.setFilters(filters);


        Map<String, String> filterChainDefinitionManager = new LinkedHashMap<String, String>();
        filterChainDefinitionManager.put("/logout", "logout");
        filterChainDefinitionManager.put("/user/**", "authc,roles[ROLE_USER]");//用户为ROLE_USER 角色可以访问。由用户角色控制用户行为。
        filterChainDefinitionManager.put("/events/**", "authc,roles[ROLE_ADMIN]");//        filterChainDefinitionManager.put("/user/edit/**", "authc,perms[user:edit]");// 这里为了测试，固定写死的值，也可以从数据库或其他配置中读取，此处是用权限控制


        filterChainDefinitionManager.put("/**", "anon");
        shiroFilterFactoryBean.setFilterChainDefinitionMap(filterChainDefinitionManager);



        shiroFilterFactoryBean.setSuccessUrl("/");
        shiroFilterFactoryBean.setUnauthorizedUrl("/403");return shiroFilterFactoryBean;
    }
/**
     * DefaultAdvisorAutoProxyCreator，Spring的一个bean，由Advisor决定对哪些类的方法进行AOP代理。
     */@Bean@ConditionalOnMissingBeanpublic DefaultAdvisorAutoProxyCreator defaultAdvisorAutoProxyCreator() {
        DefaultAdvisorAutoProxyCreator defaultAAP = new DefaultAdvisorAutoProxyCreator();
        defaultAAP.setProxyTargetClass(true);return defaultAAP;
    }
/**
     * AuthorizationAttributeSourceAdvisor，shiro里实现的Advisor类，
     * 内部使用AopAllianceAnnotationsAuthorizingMethodInterceptor来拦截用以下注解的方法。
     */@Beanpublic AuthorizationAttributeSourceAdvisor authorizationAttributeSourceAdvisor() {
        AuthorizationAttributeSourceAdvisor aASA = new AuthorizationAttributeSourceAdvisor();
        aASA.setSecurityManager(securityManager());return aASA;
    }


}

3. 添加Realm 验证

package com.us.shiro;

import com.us.bean.Permission;
import com.us.bean.Role;
import com.us.bean.User;
import com.us.dao.PermissionDao;
import com.us.dao.UserDao;
import org.apache.shiro.SecurityUtils;
import org.apache.shiro.authc.*;
import org.apache.shiro.authz.AuthorizationInfo;
import org.apache.shiro.authz.SimpleAuthorizationInfo;
import org.apache.shiro.realm.AuthorizingRealm;
import org.apache.shiro.session.Session;
import org.apache.shiro.subject.PrincipalCollection;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.beans.factory.annotation.Autowired;
/**
 * Created by cdyoue on 2016/10/21.
 */

public class ShiroRealm extends AuthorizingRealm {
    private Logger logger =  LoggerFactory.getLogger(this.getClass());

    @Autowired
    private UserDao userService;
    @Autowired
    private PermissionDao permissionService;
    @Override
    protected AuthorizationInfo doGetAuthorizationInfo(PrincipalCollection principalCollection) {
        logger.info("doGetAuthorizationInfo+"+principalCollection.toString());
        User user = userService.getByUserName((String) principalCollection.getPrimaryPrincipal());


        //把principals放session中 key=userId value=principals
        SecurityUtils.getSubject().getSession().setAttribute(String.valueOf(user.getId()),SecurityUtils.getSubject().getPrincipals());

        SimpleAuthorizationInfo info = new SimpleAuthorizationInfo();
        //赋予角色
        for(Role userRole:user.getRoles()){
            info.addRole(userRole.getName());
        }
        //赋予权限
        for(Permission permission:permissionService.getByUserId(user.getId())){
//            if(StringUtils.isNotBlank(permission.getPermCode()))
                info.addStringPermission(permission.getName());
        }

        //设置登录次数、时间
//        userService.updateUserLogin(user);
        return info;
    }

    @Override
    protected AuthenticationInfo doGetAuthenticationInfo(AuthenticationToken authenticationToken) throws AuthenticationException {
        logger.info("doGetAuthenticationInfo +"  + authenticationToken.toString());

        UsernamePasswordToken token = (UsernamePasswordToken) authenticationToken;
        String userName=token.getUsername();
        logger.info(userName+token.getPassword());

        User user = userService.getByUserName(token.getUsername());
        if (user != null) {
//            byte[] salt = Encodes.decodeHex(user.getSalt());
//            ShiroUser shiroUser=new ShiroUser(user.getId(), user.getLoginName(), user.getName());
            //设置用户session
            Session session = SecurityUtils.getSubject().getSession();
            session.setAttribute("user", user);
            return new SimpleAuthenticationInfo(userName,user.getPassword(),getName());
        } else {
            return null;
        }
//        return null;
    }

}

4. 添加controller

package com.us.controller;import org.apache.shiro.SecurityUtils;import org.apache.shiro.authc.AuthenticationException;import org.apache.shiro.authc.UsernamePasswordToken;import org.apache.shiro.subject.Subject;import org.slf4j.Logger;import org.slf4j.LoggerFactory;
import org.springframework.web.bind.annotation.*;
import java.util.HashMap;import java.util.Map;

/**
 * Created by cdyoue on 2016/10/21.
 * 登陆控制器
 */@RestControllerpublic class LoginController {private Logger logger = LoggerFactory.getLogger(this.getClass());
@RequestMapping(value = "/login", method = RequestMethod.POST)public String login(
            @RequestParam(value = "username", required = true) String userName,@RequestParam(value = "password", required = true) String password,@RequestParam(value = "rememberMe", required = true, defaultValue = "false") boolean rememberMe
    ) {
        logger.info("==========" + userName + password + rememberMe);
        Subject subject = SecurityUtils.getSubject();
        UsernamePasswordToken token = new UsernamePasswordToken(userName, password);
        token.setRememberMe(rememberMe);
try {
            subject.login(token);
        } catch (AuthenticationException e) {
            e.printStackTrace();//            rediect.addFlashAttribute("errorText", "您的账号或密码输入错误!");return "{\"Msg\":\"您的账号或密码输入错误\",\"state\":\"failed\"}";
        }return "{\"Msg\":\"登陆成功\",\"state\":\"success\"}";
    }
@RequestMapping("/")@ResponseBodypublic String index() {return "no permission";
    }
}
