传统结构项目中，shiro从cookie中读取sessionId以此来维持会话，在前后端分离的项目中（也可在移动APP项目使用），我们选择在ajax的请求头中传递sessionId，因此需要重写shiro获取sessionId的方式。自定义MySessionManager类继承DefaultWebSessionManager类，重写getSessionId方法，代码如下    

import org.apache.shiro.web.servlet.ShiroHttpServletRequest;
import org.apache.shiro.web.session.mgt.DefaultWebSessionManager;
import org.apache.shiro.web.util.WebUtils;
import org.springframework.util.StringUtils;
import javax.servlet.ServletRequest;
import javax.servlet.ServletResponse;
import java.io.Serializable;
 
/**
 * Created by Administrator on 2017/12/11.
 * 自定义sessionId获取
 */
public class MySessionManager extends DefaultWebSessionManager {
 
    private static final String AUTHORIZATION = "Authorization";
 
    private static final String REFERENCED_SESSION_ID_SOURCE = "Stateless request";
 
    public MySessionManager() {
        super();
    }
 
    @Override
    protected Serializable getSessionId(ServletRequest request, ServletResponse response) {
        String id = WebUtils.toHttp(request).getHeader(AUTHORIZATION);
        //如果请求头中有 Authorization 则其值为sessionId
        if (!StringUtils.isEmpty(id)) {
            request.setAttribute(ShiroHttpServletRequest.REFERENCED_SESSION_ID_SOURCE, REFERENCED_SESSION_ID_SOURCE);
            request.setAttribute(ShiroHttpServletRequest.REFERENCED_SESSION_ID, id);
            request.setAttribute(ShiroHttpServletRequest.REFERENCED_SESSION_ID_IS_VALID, Boolean.TRUE);
            return id;
        } else {
            //否则按默认规则从cookie取sessionId
            return super.getSessionId(request, response);
        }
    }
}

如何配置让shiro执行我们的自定义sessionManager呢？下面看ShiroConfig类。 

package com.xxx.shiro.config;
 
import org.apache.shiro.authc.credential.HashedCredentialsMatcher;
import org.apache.shiro.mgt.SecurityManager;
import org.apache.shiro.session.mgt.SessionManager;
import org.apache.shiro.spring.security.interceptor.AuthorizationAttributeSourceAdvisor;
import org.apache.shiro.spring.web.ShiroFilterFactoryBean;
import org.apache.shiro.web.mgt.DefaultWebSecurityManager;
import org.crazycake.shiro.RedisCacheManager;
import org.crazycake.shiro.RedisManager;
import org.crazycake.shiro.RedisSessionDAO;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.web.servlet.HandlerExceptionResolver;
import java.util.LinkedHashMap;
import java.util.Map;
 
/**
 * Created by Administrator on 2017/12/11.
 */
@Configuration
public class ShiroConfig {
 
    @Value("${spring.redis.shiro.host}")
    private String host;
    @Value("${spring.redis.shiro.port}")
    private int port;
    @Value("${spring.redis.shiro.timeout}")
    private int timeout;
    @Value("${spring.redis.shiro.password}")
    private String password;
 
    @Bean
    public ShiroFilterFactoryBean shirFilter(SecurityManager securityManager) {
        System.out.println("ShiroConfiguration.shirFilter()");
        ShiroFilterFactoryBean shiroFilterFactoryBean = new ShiroFilterFactoryBean();
        shiroFilterFactoryBean.setSecurityManager(securityManager);
 
        Map<String, String> filterChainDefinitionMap = new LinkedHashMap<String, String>();
        //注意过滤器配置顺序 不能颠倒
        //配置退出 过滤器,其中的具体的退出代码Shiro已经替我们实现了，登出后跳转配置的loginUrl
        filterChainDefinitionMap.put("/logout", "logout");
        // 配置不会被拦截的链接 顺序判断
        filterChainDefinitionMap.put("/static/**", "anon");
        filterChainDefinitionMap.put("/ajaxLogin", "anon");
        filterChainDefinitionMap.put("/login", "anon");
        filterChainDefinitionMap.put("/**", "authc");
        //配置shiro默认登录界面地址，前后端分离中登录界面跳转应由前端路由控制，后台仅返回json数据
        shiroFilterFactoryBean.setLoginUrl("/unauth");
        // 登录成功后要跳转的链接
//        shiroFilterFactoryBean.setSuccessUrl("/index");
        //未授权界面;
//        shiroFilterFactoryBean.setUnauthorizedUrl("/403");
        shiroFilterFactoryBean.setFilterChainDefinitionMap(filterChainDefinitionMap);
        return shiroFilterFactoryBean;
    }
 
    /**
     * 凭证匹配器
     * （由于我们的密码校验交给Shiro的SimpleAuthenticationInfo进行处理了
     * ）
     *
     * @return
     */
    @Bean
    public HashedCredentialsMatcher hashedCredentialsMatcher() {
        HashedCredentialsMatcher hashedCredentialsMatcher = new HashedCredentialsMatcher();
        hashedCredentialsMatcher.setHashAlgorithmName("md5");//散列算法:这里使用MD5算法;
        hashedCredentialsMatcher.setHashIterations(2);//散列的次数，比如散列两次，相当于 md5(md5(""));
        return hashedCredentialsMatcher;
    }
 
    @Bean
    public MyShiroRealm myShiroRealm() {
        MyShiroRealm myShiroRealm = new MyShiroRealm();
        myShiroRealm.setCredentialsMatcher(hashedCredentialsMatcher());
        return myShiroRealm;
    }
 
 
    @Bean
    public SecurityManager securityManager() {
        DefaultWebSecurityManager securityManager = new DefaultWebSecurityManager();
        securityManager.setRealm(myShiroRealm());
        // 自定义session管理 使用redis
        securityManager.setSessionManager(sessionManager());
        // 自定义缓存实现 使用redis
        securityManager.setCacheManager(cacheManager());
        return securityManager;
    }
 
    //自定义sessionManager
    @Bean
    public SessionManager sessionManager() {
        MySessionManager mySessionManager = new MySessionManager();
        mySessionManager.setSessionDAO(redisSessionDAO());
        return mySessionManager;
    }
 
    /**

     *
     * @return
     */
    public RedisManager redisManager() {
        RedisManager redisManager = new RedisManager();
        redisManager.setHost(host);
        redisManager.setPort(port);
        redisManager.setExpire(1800);// 配置缓存过期时间
        redisManager.setTimeout(timeout);
        redisManager.setPassword(password);
        return redisManager;
    }

    @Bean
    public RedisCacheManager cacheManager() {
        RedisCacheManager redisCacheManager = new RedisCacheManager();
        redisCacheManager.setRedisManager(redisManager());
        return redisCacheManager;
    }
 
    /**

        RedisSessionDAO redisSessionDAO = new RedisSessionDAO();
        redisSessionDAO.setRedisManager(redisManager());
        return redisSessionDAO;
    }
 
    /**
     * 开启shiro aop注解支持.
     * 使用代理方式;所以需要开启代码支持;
     *
     * @param securityManager
     * @return
     */
    @Bean
    public AuthorizationAttributeSourceAdvisor authorizationAttributeSourceAdvisor(SecurityManager securityManager) {
        AuthorizationAttributeSourceAdvisor authorizationAttributeSourceAdvisor = new AuthorizationAttributeSourceAdvisor();
        authorizationAttributeSourceAdvisor.setSecurityManager(securityManager);
        return authorizationAttributeSourceAdvisor;
    }
 
    /**
     * 注册全局异常处理
     * @return
     */
    @Bean(name = "exceptionHandler")
    public HandlerExceptionResolver handlerExceptionResolver() {
        return new MyExceptionHandler();
    }
}

在定义的SessionManager的Bean中返回我们的MySessionManager，然后在SecurityManager的Bean中调用setSessionManager(SessionManager sessionManager)方法加载我们的自定义SessionManager。


MyShiroRealm的代码

package com.xxx.shiro.config;
 
import com.xxx.shiro.entity.SysPermission;
import com.xxx.shiro.entity.SysRole;
import com.xxx.shiro.entity.UserInfo;
import com.xxx.shiro.service.UserInfoService;
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.subject.PrincipalCollection;
import org.apache.shiro.util.ByteSource;
 
import javax.annotation.Resource;
 
/**
 * Created by Administrator on 2017/12/11.
 * 自定义权限匹配和账号密码匹配
 */
public class MyShiroRealm extends AuthorizingRealm {
    @Resource
    private UserInfoService userInfoService;
 
    @Override
    protected AuthorizationInfo doGetAuthorizationInfo(PrincipalCollection principals) {
//        System.out.println("权限配置-->MyShiroRealm.doGetAuthorizationInfo()");
        SimpleAuthorizationInfo authorizationInfo = new SimpleAuthorizationInfo();
        UserInfo userInfo = (UserInfo) principals.getPrimaryPrincipal();
        for (SysRole role : userInfo.getRoleList()) {
            authorizationInfo.addRole(role.getRole());
            for (SysPermission p : role.getPermissions()) {
                authorizationInfo.addStringPermission(p.getPermission());
            }
        }
        return authorizationInfo;
    }
 
    /*主要是用来进行身份认证的，也就是说验证用户输入的账号和密码是否正确。*/
    @Override
    protected AuthenticationInfo doGetAuthenticationInfo(AuthenticationToken token)
            throws AuthenticationException {
//        System.out.println("MyShiroRealm.doGetAuthenticationInfo()");
        //获取用户的输入的账号.
        String username = (String) token.getPrincipal();
//        System.out.println(token.getCredentials());
        //通过username从数据库中查找 User对象，如果找到，没找到.
        //实际项目中，这里可以根据实际情况做缓存，如果不做，Shiro自己也是有时间间隔机制，2分钟内不会重复执行该方法
        UserInfo userInfo = userInfoService.findByUsername(username);
//        System.out.println("----->>userInfo="+userInfo);
        if (userInfo == null) {
            return null;
        }
        if (userInfo.getState() == 1) { //账户冻结
            throw new LockedAccountException();
        }
        SimpleAuthenticationInfo authenticationInfo = new SimpleAuthenticationInfo(
                userInfo, //用户名
                userInfo.getPassword(), //密码
                ByteSource.Util.bytes(userInfo.getCredentialsSalt()),//salt=username+salt
                getName()  //realm name
        );
        return authenticationInfo;
    }
 
}

传统项目中，登录成功后应该重定向请求，但在前后端分离项目中，通过ajax登录后应该返回登录状态标志以及相关信息。Web层登录方法代码如下

    /**
     * 登录方法
     * @param userInfo
     * @return
     */
    @RequestMapping(value = "/ajaxLogin", method = RequestMethod.POST)
    @ResponseBody
    public String ajaxLogin(UserInfo userInfo) {
        JSONObject jsonObject = new JSONObject();
        Subject subject = SecurityUtils.getSubject();
        UsernamePasswordToken token = new UsernamePasswordToken(userInfo.getUsername(), userInfo.getPassword());
        try {
            subject.login(token);
            jsonObject.put("token", subject.getSession().getId());
            jsonObject.put("msg", "登录成功");
        } catch (IncorrectCredentialsException e) {
            jsonObject.put("msg", "密码错误");
        } catch (LockedAccountException e) {
            jsonObject.put("msg", "登录失败，该用户已被冻结");
        } catch (AuthenticationException e) {
            jsonObject.put("msg", "该用户不存在");
        } catch (Exception e) {
            e.printStackTrace();
        }
        return jsonObject.toString();
    }
