springboot集成shiro 实现权限控制（转）

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

请看博文：

http://blog.csdn.net/hxpjava1/article/details/7035724

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

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;


/**

    public LifecycleBeanPostProcessor lifecycleBeanPostProcessor() {

        return new LifecycleBeanPostProcessor();

    }

    
/**

     */

    @Bean(name = "hashedCredentialsMatcher")

    public HashedCredentialsMatcher hashedCredentialsMatcher() {

        HashedCredentialsMatcher credentialsMatcher = new HashedCredentialsMatcher();

        credentialsMatcher.setHashAlgorithmName("MD5");

        return credentialsMatcher;

    }

    /**ShiroRealm，这是个自定义的认证类，继承自AuthorizingRealm，

     */

    @Bean(name = "shiroRealm")

    @DependsOn("lifecycleBeanPostProcessor")

    public ShiroRealm shiroRealm() {

        ShiroRealm realm = new ShiroRealm();

//        realm.setCredentialsMatcher(hashedCredentialsMatcher());

        return realm;

    }

//    /**

//    @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

    @ConditionalOnMissingBean

    public DefaultAdvisorAutoProxyCreator defaultAdvisorAutoProxyCreator() {

        DefaultAdvisorAutoProxyCreator defaultAAP = new DefaultAdvisorAutoProxyCreator();

        defaultAAP.setProxyTargetClass(true);

        return defaultAAP;

    }

        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

 */

@RestController

public 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("/")

    @ResponseBody

    public String index() {

        return "no permission";

    }

}

此处代码不全，只是写了springboot 整合的主要类，如果需要全部代码请移步。。。
