2. springboot+shiro+redis(单机redis版)整合教程

3. springboot+shiro+redis(集群redis版)整合教程

参考此教程前请先阅读 2.springboot+shiro+redis(单机redis版)整合教程，此教程是在其基础上进行修改添加动态角色权限的。

本教程整合环境: java8 maven redis(单机)

开发工具: idea

版本: springboot 1.5.15.RELEASE

注：

1.本教程数据操作是模拟数据库操作，并没有真正进行持久化，自行修改即可。

项目结构，在 springboot+shiro+redis(单机redis版)整合教程基础上进行的添加和修改结构如下：

首先添加角色权限实体类RolesPermissions.java

package webapp.model;

import lombok.Data;

import java.io.Serializable;

@Data
public class RolesPermissions implements Serializable {
    private static final long serialVersionUID = 1L;

    /**
     * @备注:
     * @字段:id BIGINT(19)
     */
    private Long id;


    /**
     * @备注:创建时间
     * @字段:create_time DATETIME(19)
     */
    private java.util.Date createTime;


    /**
     * @备注:更新时间
     * @字段:update_time DATETIME(19)
     */
    private java.util.Date updateTime;

    /**
     * @备注:角色id
     * @字段:roles_id BIGINT(19)
     */
    private Long rolesId;


    /**
     * @备注:权限id
     * @字段:permissions_id BIGINT(19)
     */
    private Long permissionsId;


    /**
     * @备注:角色名称
     * @字段:roles_name VARCHAR(100)
     */
    private String rolesName;


    /**
     * @备注:api接口
     * @字段:url VARCHAR(512)
     */
    private String url;


}

添加service层 RolesPermissionsService.java和 RolesPermissionsServiceImpl.java

RolesPermissionsService.java:

package webapp.service;

import webapp.model.RolesPermissions;

import java.util.List;

public interface RolesPermissionsService {
    List selectList();
    List selectByAuserName(String auserName);
}

RolesPermissionsServiceImpl.java:

package webapp.service.impl;

import org.springframework.stereotype.Service;
import webapp.model.RolesPermissions;
import webapp.service.RolesPermissionsService;

import java.util.LinkedList;
import java.util.List;

@Service
public class RolesPermissionsServiceImpl implements RolesPermissionsService {
    @Override
    public List selectList() {
        List rolesPermissionsList = new LinkedList();

        RolesPermissions rolesPermissions = new RolesPermissions();
        rolesPermissions.setId(1L);
        rolesPermissions.setPermissionsId(1L);
        rolesPermissions.setRolesId(1L);
        rolesPermissions.setRolesName("超级管理员");
        rolesPermissions.setUrl("/index.html");
        rolesPermissionsList.add(rolesPermissions);

        RolesPermissions rolesPermissions2 = new RolesPermissions();
        rolesPermissions2.setId(2L);
        rolesPermissions2.setPermissionsId(1L);
        rolesPermissions2.setRolesId(2L);
        rolesPermissions2.setRolesName("管理员");
        rolesPermissions2.setUrl("/test.html");
        rolesPermissionsList.add(rolesPermissions2);

        RolesPermissions rolesPermissions3 = new RolesPermissions();
        rolesPermissions3.setId(3L);
        rolesPermissions3.setPermissionsId(1L);
        rolesPermissions3.setRolesId(2L);
        rolesPermissions3.setRolesName("超级管理员");
        rolesPermissions3.setUrl("/test.html");
        rolesPermissionsList.add(rolesPermissions3);

        RolesPermissions rolesPermissions4 = new RolesPermissions();
        rolesPermissions4.setId(4L);
        rolesPermissions4.setPermissionsId(3L);
        rolesPermissions4.setRolesId(1L);
        rolesPermissions4.setRolesName("超级管理员");
        rolesPermissions4.setUrl("/core/user/findUser");
        rolesPermissionsList.add(rolesPermissions4);

        return rolesPermissionsList;
    }

    @Override
    public List selectByAuserName(String auserName) {
        List rolesPermissionsList = new LinkedList();
        RolesPermissions rolesPermissions = new RolesPermissions();
        rolesPermissions.setId(1L);
        rolesPermissions.setPermissionsId(1L);
        rolesPermissions.setRolesId(1L);
        rolesPermissions.setRolesName("运营管理员");
        rolesPermissions.setUrl("/index.html");
        rolesPermissionsList.add(rolesPermissions);
        return rolesPermissionsList;
    }
}

修改登录相关接口 UserController.java:

package webapp.controller;

import org.apache.shiro.SecurityUtils;
import org.apache.shiro.authc.UsernamePasswordToken;
import org.apache.shiro.session.Session;
import org.apache.shiro.subject.PrincipalCollection;
import org.apache.shiro.subject.Subject;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.data.redis.core.RedisTemplate;
import org.springframework.web.bind.annotation.*;
import webapp.service.UserService;

import javax.annotation.Resource;
import java.io.Serializable;

/**
 * Created by Administrator on 2018/9/5.
 */
@RestController
@RequestMapping("/core/user")
public class UserController {
    @Autowired
    private UserService userService;

    /**
     * 登录
     * @param
     * @return
     */
    @GetMapping("/login")
    public String login(String userName, String password) {
        System.out.println("登录" + userName);

        Subject subject = SecurityUtils.getSubject();

        UsernamePasswordToken token = new UsernamePasswordToken("admin-pc==" + userName, password);
        subject.login(token);

        Session session = subject.getSession();
        Serializable sessionId = session.getId();
        System.out.println("登录成功 -> " + sessionId);

        return userName + "[" + sessionId + "]";
    }

    @GetMapping("/logout")
    public String logout() {
        SecurityUtils.getSubject().logout();
        return "退出登录成功";
    }

    /**
     * 获取当前登录用户
     * @return
     */
    @GetMapping("/findUser")
    public String findUser() {
        Subject subject = SecurityUtils.getSubject();
        PrincipalCollection collection = subject.getPrincipals();
        if (null != collection && !collection.isEmpty()) {
            String userName = (String) collection.iterator().next();
            System.out.println("获取当前登录用户" + userName);
            return userService.findOneByUserName(userName).toString();
        }
        return "{\n" +
                "    \"codeEnum\": \"OVERTIME\",\n" +
                "    \"code\": 0,\n" +
                "    \"data\": null,\n" +
                "    \"msg\": \"未登陆/登陆超时\",\n" +
                "    \"success\": false\n" +
                "}";
    }
}

修改授权相关 UserShiroRealm.java:

package webapp.shiro;

import org.apache.shiro.SecurityUtils;
import org.apache.shiro.authc.AuthenticationException;
import org.apache.shiro.authc.AuthenticationInfo;
import org.apache.shiro.authc.AuthenticationToken;
import org.apache.shiro.authc.SimpleAuthenticationInfo;
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.session.mgt.eis.SessionDAO;
import org.apache.shiro.subject.PrincipalCollection;
import org.apache.shiro.subject.Subject;
import org.apache.shiro.subject.support.DefaultSubjectContext;
import org.springframework.beans.factory.annotation.Autowired;
import webapp.model.RolesPermissions;
import webapp.model.User;
import webapp.service.RolesPermissionsService;
import webapp.service.UserService;

import java.util.Collection;
import java.util.List;
import java.util.stream.Collectors;

/**
 * Created by Administrator on 2018/9/5.
 */
public class UserShiroRealm extends AuthorizingRealm {
    @Autowired
    private UserService userService;
    @Autowired
    private SessionDAO sessionDAO;
    @Autowired
    private RolesPermissionsService rolesPermissionsService;

    /**
     * 角色权限和对应权限添加
     * @param principalCollection
     * @return
     */
    @Override
    protected AuthorizationInfo doGetAuthorizationInfo(PrincipalCollection principalCollection) {
        String userName = (String) principalCollection.getPrimaryPrincipal();

        if (userName == null || "".equals(userName)) {
            return null;
        }else{
            userName = userName.split("==")[1];
            SimpleAuthorizationInfo authorizationInfo = new SimpleAuthorizationInfo();
            try{
                List rolesPermissions = rolesPermissionsService.selectByAuserName(userName);
                //当前用户具有的权限
                List roles = rolesPermissions.stream().map(RolesPermissions::getRolesName).collect(Collectors.toList());
                authorizationInfo.addRoles(roles);
            }catch(Exception e){
                e.printStackTrace();
            }
            return authorizationInfo;
        }
    }

    /**
     * 用户认证
     * @param authenticationToken
     * @return
     * @throws AuthenticationException
     */
    @Override
    protected AuthenticationInfo doGetAuthenticationInfo(AuthenticationToken authenticationToken) throws AuthenticationException {
        //加这一步的目的是在Post请求的时候会先进认证，然后在到请求
        if (authenticationToken.getPrincipal() == null) {
            return null;
        }

        String userName = authenticationToken.getPrincipal().toString();

        //只允许同一账户单个登录
        Subject subject = SecurityUtils.getSubject();
        Session nowSession = subject.getSession();
        Collection sessions = sessionDAO.getActiveSessions();
        if(sessions != null && sessions.size() > 0) {
            for (Session session : sessions) {
                if (!nowSession.getId().equals(session.getId()) && (session.getTimeout() == 0
                        || userName.equals(String.valueOf(session.getAttribute(DefaultSubjectContext.PRINCIPALS_SESSION_KEY))))) {
                    sessionDAO.delete(session);
                }
            }
        }

        User user = userService.findOneByUserName(userName.contains("admin-pc==") ? userName.split("==")[1] : userName);
        if (user == null) {
            return null;
        } else {
            //这里验证authenticationToken和simpleAuthenticationInfo的信息
            return new SimpleAuthenticationInfo(userName, user.getPassword(), getName());
        }
    }
}

自定义角色权限校验器roleOrFilter(注:默认的roles为and关系，由于实际项目需要更多为或者关系，故自定义此类) CustomRolesAuthorizationFilter.java:

package webapp.shiro;

import org.apache.shiro.subject.PrincipalCollection;
import org.apache.shiro.subject.Subject;
import org.apache.shiro.web.filter.authz.AuthorizationFilter;
import webapp.model.RolesPermissions;
import webapp.redis.RedisCache;
import webapp.service.RolesPermissionsService;

import javax.servlet.ServletRequest;
import javax.servlet.ServletResponse;
import java.util.Arrays;
import java.util.Collections;
import java.util.List;
import java.util.Set;
import java.util.stream.Collectors;

public class CustomRolesAuthorizationFilter extends AuthorizationFilter {
    //项目名-用于多项目共用redis缓存时区分项目
    private static final String PROJECTNAME = "shiro5";
    private RolesPermissionsService rolesPermissionsService;
    private RedisCache redisCache;

    public CustomRolesAuthorizationFilter(RolesPermissionsService rolesPermissionsService, RedisCache redisCache) {
        this.rolesPermissionsService = rolesPermissionsService;
        this.redisCache = redisCache;
    }

    @Override
    public boolean isAccessAllowed(ServletRequest request, ServletResponse response, Object mappedValue) throws Exception {
        Subject subject = getSubject(request, response);
        PrincipalCollection principals = subject.getPrincipals();

        //未登录情况
        if (null == principals) {
            return false;
        }

        String userName = principals.toString();
        String userName0 = userName.split("==")[0];

        String[] rolesArray = (String[]) mappedValue;
        if (rolesArray == null || rolesArray.length == 0) {
            return true;
        }

        //当前请求URI所需要的角色
        List rolesList = Arrays.asList(rolesArray);

        String userName1 = "";
        //redis缓存中当前登录用户的角色(注:更改用户角色时需要更新此缓存)
        Object cache = redisCache.getCache(PROJECTNAME + "==isAccessAllowed==" + userName);

        if ("admin-pc".equals(userName0)) {
            if (null != cache) {
                Set cache1 = (Set) cache;
                boolean disjoint = Collections.disjoint(cache1, rolesList);
                return !disjoint;
            }
            userName1 = userName.split("==")[1];
        }

        List rolesPermissions;
        if ("admin-pc".equals(userName0)) {
            rolesPermissions = rolesPermissionsService.selectByAuserName(userName1);
        } else {
            return true;
        }

        //当前用户具有的权限
        Set roles = rolesPermissions.stream().map(RolesPermissions::getRolesName).collect(Collectors.toSet());

        //往redis缓存中存储当前登录用户的角色(注:更改用户角色时需要更新此缓存)
        redisCache.putCacheWithExpireTime(PROJECTNAME + "==isAccessAllowed==" + userName, roles, 86400); //24小时过期

        boolean disjoint = Collections.disjoint(roles, rolesList);

        return !disjoint;

    }

}

使用自定义的角色权限校验器roleOrFilter，ShiroPermissionFactory.java:

package webapp.shiro;

import org.apache.shiro.config.Ini;
import org.apache.shiro.spring.web.ShiroFilterFactoryBean;
import org.apache.shiro.web.config.IniFilterChainResolverFactory;
import org.springframework.util.CollectionUtils;
import webapp.model.RolesPermissions;
import webapp.service.RolesPermissionsService;

import java.util.*;

public class ShiroPermissionFactory extends ShiroFilterFactoryBean {
    /**记录配置中的过滤链*/
    public static String definition = "";
    private RolesPermissionsService rolesPermissionsService;

    public ShiroPermissionFactory(RolesPermissionsService rolesPermissionsService){
        this.rolesPermissionsService = rolesPermissionsService;
    }

    /**
     * 初始化设置过滤链
     */
    @Override
    public void setFilterChainDefinitions(String definitions) {

        definition = definitions;//记录配置的静态过滤链

        List rolesPermissions = rolesPermissionsService.selectList();
        Set urls = new LinkedHashSet();
        for (RolesPermissions rolesPermission : rolesPermissions) {
            urls.add(rolesPermission.getUrl());
        }

        Map otherChains = new HashMap();
        for (String url : urls) {
            StringBuilder roleOrFilters = new StringBuilder();
            int j = 0;
            for (int i = 0; i ) {
                if (Objects.equals(url, rolesPermissions.get(i).getUrl())) {
                    if (j == 0) {
                        j = 1;
                        roleOrFilters.append(rolesPermissions.get(i).getRolesName());
                    } else {
                        roleOrFilters.append(",").append(rolesPermissions.get(i).getRolesName());
                    }
                }
            }
            String rolesStr = roleOrFilters.toString();
            if (!"".equals(rolesStr)) {
                otherChains.put(url, "roleOrFilter[" + rolesStr + "]");
            }
        }
        //加载配置默认的过滤链
        Ini ini = new Ini();
        ini.load(definitions);
        Ini.Section section = ini.getSection(IniFilterChainResolverFactory.URLS);
        if (CollectionUtils.isEmpty(section)) {
            section = ini.getSection(Ini.DEFAULT_SECTION_NAME);
        }
        //加上数据库中过滤链
        section.putAll(otherChains);
        setFilterChainDefinitionMap(section);
    }
}

shiro配置类ShiroConfig.java修改如下：

                    chains.forEach((url, definitionChains) -> {
                        manager.createChain(url, definitionChains.trim().replace(" ", ""));
                    });
                }
            } catch (Exception e) {
                e.printStackTrace();
            }
        }
    }
}

角色权限刷新器FilterChainDefinitions.java的使用示例TestController.java:

package webapp.controller;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;
import webapp.shiro.FilterChainDefinitions;

@RestController
@RequestMapping("/core/test")
public class TestController {
    @Autowired
    private FilterChainDefinitions filterChainDefinitions;


    @GetMapping("/test")
    public void test() {
        //设置用户权限
        //...
        //刷新权限
        filterChainDefinitions.reloadFilterChains();
    }
}

然后启动项目，RolesPermissionsServiceImpl.java类中的获取数据库(模拟)中所有角色权限和获取用户角色权限可自行修改测试。实际应用于项目也只需要修改这个类为查询实际数据库数据即可。
